NOMENCLATURAL COMMENTS Schelpe (1967) cited two sheets at K as the lectotype of Blechnum bakeri, and only conducted the valid first-step lectotypification of the name (Art. 9.17 of ICN; Turland et al. 2018). Since those two sheets at K are not clearly labeled as being part of a single specimen (Art. 8.3 of ICN; Turland et al. 2018), we here conducted the second-step lectotypification, selecting the sheet with two isolated sterile fronds (annotated E, F). From the same sheet K000424012, the two fertile fronds (annotated G, H) are excluded from the lectotype, as they must be following the first-step lectotypification (Schelpe 1967); we however ascribed the fertile frond H to Cranfillia bakeri Vázquez Ferreira & S.Molino, comb. nov., while frond G was ascribed to Lomaridium biforme (Baker) Gasper & V.A.O.Dittrich. In the protologue of Blechnum bakeri var. glabrum, Bonaparte (1918) cited C. d’Alleizette 82 (in the Bonaparte’s Herbarium) as the type. This gathering is represented by a single sheet at P, which is the holotype; Rakotondrainibe et al. (2013) erroneously cited P00483199 as an isotype, as this latter sheet in fact belongs to the distinct gathering C. d’Alleizette 82m (i.e. including “m” as a suffix)., Published as part of Bauret, Lucie, Vázquez, Rubén, Molino, Sonia, Gaudeul, Myriam, Rakotondrainibe, France, Gasper, André Luís de & Rouhan, Germinal, 2020, New molecular and morphological evidences favor a combination of Blechnum bakeri C.

107. Systematics and Plastome Evolution in Schizaeaceae.

Abstract

While the family Schizaeaceae (Schizaeales) represents only about 0.4% of the extant fern species diversity, it differs from other ferns greatly in gross morphologies, niche preferences, and life histories. One of the most notable features in this family is its mycoheterotrophic life style in the gametophytic stage, which appears to be associated with extensive losses of plastid genes. However, the limited number of sequenced plastomes, and the lack of a wellresolved phylogenetic framework of Schizaeaceae, makes it difficult to gain any further insight. Here, with a comprehensive sampling of ~77% of the species diversity of this family, we first inferred a plastid phylogeny of Schizaeaceae using three DNA regions. To resolve the deep relationships within this family, we then reconstructed a plastome-based phylogeny focusing on a selection of representatives that covered all the major clades. From this phylogenomic backbone, we traced the evolutionary histories of plastid genes and examined whether gene losses were associated with the evolution of gametophytic mycoheterotrophy. Our results reveal that extant Schizaeaceae is comprised of four major clades--Microschizaea, Actinostachys, Schizaea, and Schizaea pusilla. The loss of all plastid NADH-like dehydrogenase (ndh) genes was confirmed to have occurred in the ancestor of extant Schizaeaceae, which coincides with the evolution of mycoheterotrophy in this family. For chlorophyll biosynthesis genes (chl), the losses were interpreted as convergent in Schizaeaceae, and found not only in Actinostachys, a clade producing achlorophyllous gametophytes, but also in S. pusilla with chlorophyllous gametophytes. In addition, we discovered a previously undescribed but phylogenetically distinct species hidden in the Schizaea dichotoma complex and provided a taxonomic treatment and morphological diagnostics for this new species--Schizaea medusa. Finally, our phylogenetic results suggest that the current PPG I circumscription of Schizaea is non-monophyletic, and we therefore proposed a three-genus classification moving a subset of Schizaea species sensu PPG I to a third genus--Microschizaea.

Abstract

Host-parasite coevolution can maintain high levels of genetic diversity in traits involved in species interactions. In many systems, host traits exploited by parasites are constrained by use in other functions, leading to complex selective pressures across space and time. Here, we study genome-wide variation in the staple crop Sorghum bicolor (L.) Moench and its association with the parasitic weed Striga hermonthica (Delile) Benth., a major constraint to food security in Africa. We hypothesize that geographic selection mosaics across gradients of parasite occurrence maintain genetic diversity in sorghum landrace resistance. Suggesting a role in local adaptation to parasite pressure, multiple independent loss-of-function alleles at sorghum LOW GERMINATION STIMULANT 1 (LGS1) are broadly distributed among African landraces and geographically associated with S. hermonthica occurrence. However, low frequency of these alleles within S. hermonthica-prone regions and their absence elsewhere implicate potential trade-offs restricting their fixation. LGS1 is thought to cause resistance by changing stereochemistry of strigolactones, hormones that control plant architecture and below-ground signaling to mycorrhizae and are required to stimulate parasite germination. Consistent with trade-offs, we find signatures of balancing selection surrounding LGS1 and other candidates from analysis of genome-wide associations with parasite distribution. Experiments with CRISPR-Cas9-edited sorghum further indicate that the benefit of LGS1-mediated resistance strongly depends on parasite genotype and abiotic environment and comes at the cost of reduced photosystem gene expression. Our study demonstrates long-term maintenance of diversity in host resistance genes across smallholder agroecosystems, providing a valuable comparison to both industrial farming systems and natural communities.

113. New insights into the diversity, taxonomy and history of the fern genus Trichomanes (Hymenophyllaceae, Polypodiidae), with a focus on Africa and the western Indian Ocean.

Abstract

The filmy fern genus Trichomanes mainly comprises Neotropical species and a few taxa in Africa and the western Indian Ocean. The aim of this study is to infer the phylogenetic placement of all five Afro-Malagasy taxa in the genus and to investigate their history via an expanded and dated phylogenetic analysis including 39 species representing over half the diversity of the genus. The results support the monophyly of Trichomanes including all the sampled species attributed to the genus, but also suggest the inclusion of the species Abrodictyum cellulosum , revealing a morphological diversity of the genus greater than what was traditionally recognized, and highlighting the importance of the campanulate sorus as a generic diagnostic character. To accommodate those new phylogenetic results and morphological investigations, we describe a new subgenus Afrotrichomanes grouping the Afro-Malagasy taxa (except T. crenatum). The dated history of the genus among the trichomanoids suggests at least two origins for the Palaeotropical species. A recent Cainozoic colonization from the Neotropics towards Africa gave rise to the West African taxon T. crenatum , and a possible Mesozoic vicariance event gave rise to subgenus Afrotrichomanes. The low species diversity of the genus in the Afro-Malagasy region is discussed. [ABSTRACT FROM AUTHOR]

Abstract

Two East Asian Lomariopsis (Lomariopsidaceae, Polypodiales) species, Lomariopsis moorei and Lomariopsis longini, which were previously misidentified as L. spectabilis, are here described as new species based on evidence from morphological characters and a molecular phylogeny. The two species differ from the three other described species in East Asia by their venation, pinna shapes, and perine morphology. A phylogeny based on a combined dataset of three chloroplast regions (rbcL+ rps4-trnS + trnL-L-F) showed that L. moorei and L. longini each formed a well-supported monophyletic group which was distantly related to both L. spectabilis and the other morphologically similar East Asian species, L. boninensis.

Abstract

Ceradenia pseudodevoluta Rakotondr. & Parris, sp. nov. (Fig. 2 A-G) Ceradenia pseudodevoluta Rakotondr. & Parris , sp. nov., differs from Zygophlebia devoluta (Baker) Parris in having paraphyses which produce whitish waxy exudate (vs paraphyses which produce grey sticky exudate) and membranaceous rhizome scales with flattened, shortly acuminate apex (vs turgescent rhizome scales with cylindrical, long acuminate apex). Ceradenia pseudodevoluta Rakotondr. & Parris , sp. nov. differs from Ceradenia comorensis (Baker) Parris in having glandulous rhizome scales with cells 1-3 times longer than wide (vs eglandular scales with cells 4-6 times longer than wide).

121. Diversity and taxonomy of the fern genus VandenboschiaCopel. (Hymenophyllaceae, Polypodiidae) in the Afro-Malagasy region and description of a new species

Abstract

ABSTRACTVandenboschia radicans(supposedly Neotropical and African), V. speciosa(supposedly European and Macaronesian) and V. gigantea(supposedly from western Indian Ocean) are morphologically close species and often confused in collections and in floras. Moreover, the status of African populations is still strongly debated. We undertook to combine morphological, morphometrics and molecular phylogenetic analyses, on these three species, by also including the Neotropical V. collariata, morphologically close to V. radicans, to try to discriminate putative geographical lineages and discuss their taxonomic status. Our results show that V. collariatais distinct from the other species, and that V. radicans, V. speciosa, V. giganteaand the African specimens remain morphologically and morphometrically indistinguishable. Nevertheless, the Neotropical specimens of V. radicans, V. speciosaand V. giganteaare each genetically strongly distinct and are thus clearly supported as distinct species. African specimens are all grouped into a distinct clade sister to V. giganteaand are distinguished by the presence of a well-developed wing on the stipe, lacking in V. gigantea. Taking into account this stipe feature as well as genetic differences, we describe here Vandenboschia confusaas a new species corresponding to the African populations. The origin of this species in the region is discussed, in addition to the complex taxonomy of European-Macaronesian V. speciosa.

122. (3006) Proposal to conserve the name Sticherus (Gleicheniaceae) with a conserved type.

Author

Lima, Lucas Vieira, Almeida, Thaís Elias, Kessler, Michael, Rouhan, Germinal, and Salino, Alexandre

Abstract

The article proposes to conserve the name Sticherus in the Gleicheniaceae family. Sticherus is the largest genus in the family, with approximately 95 recognized species found in Africa, Asia, Oceania, and the Americas. The genus was established in 1836 and initially included two species, but one of them is now recognized as belonging to a different genus. A recent phylogenomic study found Sticherus to be paraphyletic, with two distinct clades. To achieve monophyletic genera, the authors propose either recognizing both clades as separate genera or conserving the name Sticherus with a new type species. The authors argue for conserving the name Sticherus due to its widespread usage and the large number of specimens and publications associated with it. [Extracted from the article]

Abstract

International audience; Within the context of the revision of grammitid ferns from Madagascar, eleven new taxa (ten species and one variety) are described and illustrated: Ceradenia ivohibensis Rakotondr. & Parris, sp. nov., Ceradenia pseudodevoluta Rakotondr. & Parris, sp. nov., Ctenopterella lastii Parris & Rakotondr., sp. nov., Enterosora sinuata Rakotondr. & Parris, sp. nov., Grammitis anisophylla Rakotondr. & Parris, sp. nov., Grammitis coriaceifolia Rakotondr. & Parris, sp. nov., Grammitis dauphinensis Rakotondr. & Parris, sp. nov., Grammitis membranifolia Rakotondr. & Parris, sp. nov., Melpomene flabelliformis (Poir.) A.R. Sm. & R.C. Moran var. circumvoluta Rakotondr. & Parris, var. nov., Moranopteris madagascarica Rakotondr. & Parris, sp. nov., and Zygophlebia rouxii Rakotondr. & Parris, sp. nov. The nomenclature adopted here follows PPG1 (2016) except for the genus Grammitis, which is considered here in its broad sense: it includes all species with lamina entire to lobate, those with a sclerotic margin (= Grammitis s. str.) and those with an undifferentiated margin. The discriminating morphological characters of the eleven genera present in Madagascar are specified in the original determination key given at the beginning of the treatment. In the context of a still unsettled classification of grammitid ferns, the purpose of this key is to argue the choice of the generic classification of the new species described.A new presumed hybrid, Zygophlebia devoluta (Baker) Parris × Ceradenia pseudodevoluta Rakotondr. & Parris, sp. nov., is also described and compared with its putative parents. Three new combinations are proposed: Ctenopterella boivinii (Mett. ex Kuhn) Rakotondr. & Parris, comb. nov., Enterosora uluguruensis (Reimers) Rakotondr. & Parris, comb. nov., and Stenogrammitis micropecten (C. Chr.) Rakotondr. & Parris, comb. nov.; Enterosora uluguruensis (Reimers) Rakotondr. & Parris, comb. nov., an African species, is recorded for the first time in Madagascar. Finally, a new synonymy is published: Ceradenia alboglandulosa (Bonap.) Parris, synonym of Ceradenia deltodon (Baker) Parris.; Dans le cadre de la révision des fougères grammitides (Pteridophyta, Polypodiaceae, Grammitidoideae) de Madagascar, onze taxons nouveaux (dix espèces et une variété) sont décrits et illustrés: Ceradenia ivohibensis Rakotondr. & Parris, sp. nov., Ceradenia pseudodevoluta Rakotondr. & Parris, sp. nov., Ctenopterella lastii Parris & Rakotondr., sp. nov., Enterosora sinuata Rakotondr. & Parris, sp. nov., Grammitis anisophylla Rakotondr. & Parris, sp. nov., Grammitis coriaceifolia Rakotondr. & Parris, sp. nov., Grammitis dauphinensis Rakotondr. & Parris, sp. nov., Grammitis membranifolia Rakotondr. & Parris, sp. nov., Melpomene flabelliformis (Poir.) A.R. Sm. & R.C. Moran var. circumvoluta Rakotondr. & Parris, var. nov., Moranopteris madagascarica Rakotondr. & Parris, sp. nov., et Zygophlebia rouxii Rakotondr. & Parris, sp. nov. La nomenclature adoptée est conforme à celle du PPG1 (2016) sauf pour le genre Grammitis qui est considéré ici dans son sens large, c’est-à-dire qui inclut toutes les espèces à limbe entier à lobé, celles présentant une marge scléreuse (= Grammitis s. str.) et celles avec une marge indifférenciée. Les caractères morphologiques discriminants des onze genres présents à Madagascar sont précisés dans une clé de détermination originale donnée en début du traitement. Dans le contexte d’une classification des fougères grammitides non encore stabilisée, le but de cette clé est d’argumenter le choix du classement générique des nouvelles espèces décrites. Un hybride présumé, Zygophlebia devoluta (Baker) Parris × Ceradenia pseudodevoluta Rakotondr. & Parris, sp. nov., est également décrit et comparé à ses deux parents potentiels. Trois combinaisons nouvelles sont proposées: Ctenopterella boivinii (Mett. ex Kuhn) Rakotondr. & Parris, comb. nov., Enterosora uluguruensis (Reimers) Rakotondr. & Parris, comb. nov., et Stenogrammitis micropecten (C. Chr.) Rakotondr. & Parris, comb. nov.; Enterosora uluguruensis (Reimers) Rakotondr. & Parris, comb. nov.,espèce africaine, est signalée pour la première fois à Madagascar. Enfin, une synonymie nouvelle est publiée: Ceradenia alboglandulosa (Bonap.) Parris synonyme de Ceradenia deltodon (Baker) Parris.

Abstract

International audience; Background: The present work proposes, for the first time, a study exclusively focused on the diversity of Pteridophytes in Togo.The study was based on fieldwork that resulted in 869 new collections gathered between 2013 and 2017 in the country and on yet existing herbarium specimens kept at the Herbaria of Lomé and Paris. Thus, a total number of 1092 specimens collected throughout the country served as a basis for this work, to which were added the known, published occurrences of Pteridophytes for the country.New information: At the end of this study, a total diversity of 134 species belonging to 53 genera and 25 families and 12 orders were recorded and documented for the country. It results in 73 newly cited species for Togolese flora, including 61 spontaneous species. Lycopodiopsida (18 species) and Polypodiopsida (116 species) classes are both represented. The Polypodiales order is the most represented with 97 species. The Pteridaceae and Aspleniaceae families are the most diverse with 24 and 22 species respectively. Finally, notes were provided on species distribution at national level.

Abstract

The thelypteroid fern genus Stegnogramma s.l. contains around 18–35 species and has a global, cross‐continental distribution ranging from tropical to temperate regions. Several genera and infrageneric sections have been recognized previously in Stegnogramma s.l., but their phylogenetic relationships are still unclear. In this study, we present a global phylogeny of Stegnogramma s.l. with the most comprehensive sampling to date and aim to pinpoint the phylogenetic positions of biogeographically and taxonomically important taxa. Based on the reconstructed historical biogeography and character evolution, we propose a new (infra)generic classification and discuss the diversification of Stegnogramma s.l. in a biogeographical context. New names or combinations are made for 12 (infra)species, including transferring the monotypic species of Craspedosorus to Leptogramma. Finally, we discuss a possible link between leaf architecture and ecological adaptation, and hypothesize that the increase in leaf dissection and free‐vein proportion is an adaptive feature to cool climates in Stegnogramma s.l.

Abstract

International audience; We provide a quantitative description of the French national herbarium vascular plants collection dataset. Held at the Muséum national d'histoire naturelle, Paris, it currently comprises records for 5,400,000 specimens, representing 90% of the estimated total of specimens. Ninety nine percent of the specimen entries are linked to one or more images and 16% have field-collecting information available. This major botanical collection represents the results of over three centuries of exploration and study. The sources of the collection are global, with a strong representation for France, including overseas territories, and former French colonies. The compilation of this dataset was made possible through numerous national and international projects, the most important of which was linked to the renovation of the herbarium building. The vascular plant collection is actively expanding today, hence the continuous growth exhibited by the dataset, which can be fully accessed through the GBIF portal or the MNHN database portal (available at: https://science.mnhn.fr/institution/mnhn/collection/p/item/search/form). This dataset is a major source of data for systematics, global plants macroecological studies or conservation assessments.

Abstract

International audience; Phylogeny has long informed pteridophyte classification. As our ability to infer evolutionary trees has improved, classifications aimed at recognizing natural groups have become increasingly predictive and stable. Here, we provide a modern, comprehensive classification for lycophytes and ferns, down to the genus level, utilizing a community-based approach. We use monophyly as the primary criterion for the recognition of taxa, but also aim to preserve existing taxa and circumscriptions that are both widely accepted and consistent with our understanding of pteridophyte phylogeny. In total, this classification treats an estimated 11 916 species in 337 genera, 51 families, 14 orders, and two classes. This classification is not intended as the final word on lycophyte and fern taxonomy, but rather a summary statement of current hypotheses, derived from the best available data and shaped by those most familiar with the plants in question. We hope that it will serve as a resource for those wanting references to the recent literature on pteridophyte phylogeny and classification, a framework for guiding future investigations, and a stimulus to further discourse.

Abstract

The inventory of biodiversity in the Comoros archipelago is still in progress. We propose here to contribute to this effort by assessing the diversity of the Hymenophyllaceae family, which forms one of the most diverse and emblematic fern communities in rainforests of the region. Data were extracted from floras, literature, recent collects and observations, and from an exhaustive investigation of the Paris herbarium collection. We also completed an online knowledge database including a computeraided identification (CAI) tool by using the Xper platform. Our checklist recognizes 21 taxa involving 1 endemic and 7 species newly reported for the archipelago. The taxonomy and discrimination of each taxon is discussed and a dichotomous key is provided. We also defined 80 morphological characters and their corresponding states into the Xper database and CAI that could be easily enriched for neighbouring areas and additional taxa.

Abstract

The fern flora of the Seychelles archipelago remains relatively poorly known. Recent projects involving the development of the Seychelles National Herbarium and study of key biodiversity areas have resulted in extensive explorations of the ferns on the granitic islands. Historical literature, newly collected specimens and older collections have been revised for the fern family Hymenophyllaceae as a prelude for a fern checklist, resulting in several discoveries. In Didymoglossum, specimens were found with a very unusual character: exsert sori. Revision of the specimens, including phylogenetic analyses, revealed that these belong to two distinct species: Didymoglossum beccarianum comb. nov. (until now only known from Southeast Asia) and a new species endemic to Seychelles, which is described as D. beaverianum below. The exact identity of the Southeast Asian species required to review a complex of species previously considered synonymous to D. motleyi. As a result, we propose a taxonomic hypothesis where Didymoglossum motleyi is in fact known from the type only (from Borneo); D. beccarianum includes the synonyms Trichomanes cognatum, T. sayeri and T. minutissimum and is widely distributed from Seychelles to the western Pacific Ocean and finally Didymoglossum (Trichomanes) cultratum comb. nov. which is maintained as a separate species (endemic to Fiji and known from the type only). We conclude by emphasizing the main diagnostic characters in this complex of species, including characters that have been neglected in the past., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

Rumohra is a fern genus comprising seven species, three in South America, three in Madagascar and one (R. adiantiformis) which is widely distributed across the Southern Hemisphere. Our goals were to assess species delimitation based on molecular data and to infer the biogeographical history that led to such contrasting distributions among species. We sampled all Rumohra spp. with 46 samples including 28 R. adiantiformis accessions from 14 regions, and sequenced eight plastid DNA regions: atpA, atpB, atpB-rbcL, rbcL, rps4-trnS, trnG-trnR, trnH-psbA and trnL/trnLtrnF. The resulting phylogenetic trees showed R. adiantiformis to be polyphyletic, with at least six lineages found in distinct geographical regions. Given the apparent absence of distinctive morphological characters among lineages, they are best understood as cryptic species. Such genetically distinct but morphologically similar populations may result from a recurrent history of hybridization, morphological convergence or (most probably) morphological stasis. Molecular dating and ancestral area estimations showed that Rumohra diverged from the genus Megalastrum c. 46.4 Mya in the Neotropics, and started to diversify 11.2 Mya. Its biogeographical history was probably shaped by seven long-distance dispersal (LDD) events including three initial events from the Neotropics to southern Africa, the Malagasy region and southern South America. The Australasian lineage resulted from a LDD from southern South America, and the three species endemic to Madagascar diversified in situ., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

The filmy fern Abrodictyum cupressoides, initially reported from Madagascar and the Seychelles (locus classicus), is often confused in the field and in collections with similar local species, especially the pantropical A. rigidum. A comparative morphological investigation of Malagasy and Seychellois specimens finds strong differences between A. cupressoides and A. rigidum as well as between Malagasy and Seychellois A. cupressoides, suggesting three distinct morpho-species. A molecular phylogeny based on rbcL sequences focused on the genus Abrodictyum shows the polyphyly of both A. cupressoides and A. rigidum, and reveals that A. cupressoides should be excluded from Abrodictyum, would belong to Trichomanes and is restricted to the Seychelles. A new description for Seychellois Trichomanes cupressoides is thus proposed. In addition, generic treatments for Malagasy T. pachyphlebium, T. madagascariense, T. boivinii and African A. guineense are discussed., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

Abstract: Deparia, including the previously recognized genera Lunathyrium, Dryoathyrium (=Parathyrium), Athyriopsis, Triblemma, and Dictyodroma, is a fern genus comprising about 70 species in Athyriaceae. In this study, we inferred a robust Deparia phylogeny based on a comprehensive taxon sampling (~81% of species) that captures the morphological diversity displayed in the genus. All Deparia species formed a highly supported monophyletic group. Within Deparia, seven major clades were identified, and most of them were characterized by inferring synapomorphies using 14 morphological characters including leaf architecture, petiole base, rhizome type, soral characters, spore perine, and leaf indument. These results provided the morphological basis for an infra‐generic taxonomic revision of Deparia. [ABSTRACT FROM AUTHOR]
