Note. – The type of Iresine edmonstonei that was collected by Edmonston might have been from a plant introduced by early settlers or the specimen was mislabeled to originate from Galapagos (Eliasson, 1985). The folder of I. elatior in the Willdenow herbarium (B) contains four sheets, only two of which have labels. Sheet 0 4 is the only one with a label saying “ Iresine – spec. nova”. The fact that the folder itself contains on its inside three more labels, out of the hand of Bonpland as well as Schlechtendahl (H.W. Lack, pers. comm.) is a further indication of a different origin of the sheets but also that these three labels cold not unambiguously be assigned to any of the sheets. A lectotypification is therefore warranted. The geographic origin of the specimens is unknown. The type specimen of I. laxissima is from a hermaphroditic plant and has only bisexual flowers. The name “ Rosea poeppigiana Klotzsch ” is not validly published but was listed by Seubert (1875) as a synonym of I. elatior Rich. ex Willd. There is a specimen in B (E.F. Poeppig s.n., B 10 0 242399, from Brazil, Pará) annotated with the name “ Rosea poeppigiana Kl. ”. The handwriting is clearly by J.F. Klotzsch (R. Vogt, pers. comm.). Seubert cited this name as it was often practised at the time.

Note. – No lectotypification of Iresine latifolia was made by Pedersen (1997), who also cited a wrong collector’s number (Galeotti 520) for the type. The two Galeotti specimens mentioned in the protologue are numbers 420 and 423. We have selected Galeotti 423, the sheet with barcode 0 0 0 0 0 6952501, which has the more complete label; the isolectotype could be a duplicate for which a simpler label was just written by hand. Standley (1916) erroneously made a new combination using Achyranthes calea Ibáñez as basionym, assuming that “ Iresine latifolia D. Dietr. ” was already available as a validly published name. However, as pointed out by Pedersen (1997) the name Iresine latifolia appears nowhere on p. 870 in Dietrich’s Synopsis plantarum (vol. 1, 1839), although this is cited by Moquin-Tandon (1849: 351). On the other hand, Moquin-Tandon mentiones two pages earlier (p. 349) “ Iresine latifolia = Alternanthera pulverulenta ”, which apparently is an error because Alternanthera latifolia is the next entry on p. 351 of Moquin’s treatment. No specimen of I. latifolia var. velutina could be localized at B. The existence of duplicates that could serve as lectotypes cannot be excluded as Endlich specimens are in various herbaria such as G, L and MO (electronic search so far not successful).

Note. – The Aschenborn specimen at FR that is designated as the lectotype of Iresine cassiniiformis is from the herbarium of Sebastian Schauer (see also comment in sched. by S. Becker 2012) and therefore clearly is historical material that qualifies as a lectotype. The protologue cites the Aschenborn collection numbers 169, 617 and 618, none of which could be localized so far in any herbarium. Aschenborn collected in Mexico from 1839 to 1841 and sent specimens to several European herbaria (see Butzin, 1985). More than 700 specimens were deposited in Berlin, from which only a small proportion survived the destructions of the Second World War. Today, no Aschenborn specimen of I. cassiniiformis is present in B (R. Vogt, pers. comm.).

Note. – For Iresine mutisii there is no designation of any holotype nor any citation of a specimen in the protologue; but the Paris herbarium holds a specimen that might have been used as a type. It has an original label saying “Herbier donné par M. Bonpland en 1833”, which corresponds to the note published at the end of the protologue “A Mutisio cum Bonplandio communicata”. Other Mutis material in US was collected later and came there via Madrid. In order to describe I. polymorpha, Martius worked on Sellow specimens from B (H. Esser, pers. comm.) and the specimen in P has a label “Herb. Reg. Berolinense” but no material could now be located at B. The P specimen therefore is the best original material for lectotypification, assuming that the holotype in B was destroyed in the second world war. As frequently practiced at this time, no nominate variety was established by Martius (1826). Because “β effusa ” is mentioned on the original label, we treat the nominate variety as a synonym of var. effusa with the same type. No specimen exists of I. papantlana at B. It is very likely that the holotype was destroyed during the second world war, but duplicate original material with a Berlin label exists in GH. The specimen of I. pilgeri at S was labeled as the type by Suessenguth in 1934, whereas he put annotations on the B and K specimens as “co-types”. Suessenguth cites Klug 1893 as the only specimen of I. polymorpha var. verticillata f. albonervosa in the protologue. However, one year earlier, when describing I. spiculigera f. picta Suess. he mentioned the same specimen among the syntypes “desgl. 1893”. So he probably decided later that this specimen should be treated as a different entity. So far this specimen could not be localized in any herbarium. The specimen G. Klug 1756 is one of the syntypes of I. spiculigera f. picta but the locality of G. Klug 1756 is identical to G. Klug 1893. Since none of the other syntypes could so far be localized a lectotypification is premature as the correct assignment of label data in the publication needs to be checked. Eliasson (1987) did some morphometrics supporting the differentiation of var. spiculigera as a high-elevation Andean taxon. However, his study was only including material from Ecuador, so that the status of this variety within the total variation of Iresine diffusa requires further study before recognizing this and other infraspecific taxa. Taxonomic status: Probably not a monophylum as currently defined, requires further study (C)., Published as part of Thomas Borsch, Hilda Flores-Olvera, Silvia Zumaya & Kai Müller, 2018, Pollen characters and DNA sequence data converge on a monophyletic genus Iresine (Amaranthaceae, Caryophyllales) and help to elucidate its species diversity, pp. 944-976 in Taxon 67 (5) on pages 966-967, DOI: 10.12705/675.7, http://zenodo.org/record/1488314, {"references":["Martius, C.
