Diospyros venablesii W.E.Cooper is described and illustrated with notes on habitat, distribution and how to distinguish it from the most similar species, Diospyros laurina. [ABSTRACT FROM AUTHOR]

Calandrinia petrophila J.G.West & Albr. sp. nov. is described and illustrated, with notes on distribution, habitat, conservation status and features distinguishing it from similar species of Calandrinia. [ABSTRACT FROM AUTHOR]

The correct citation for Grevillea manglesii (Proteaceae) is G. manglesii Pépin (1838). A neotype is here selected from among historic collections, now at Paris (P). Should the minimal description provided by Pépin be successfully challenged as inadequate, the name would not change but the revised authority would be Grevillea manglesii (Graham) A.Baumann and N.Baumann (1843). The origins and complex taxonomic and horticultural history of G. manglesii and its synonyms Manglesia glabrata Lindl., Anadenia manglesii Graham, Grevillea manglesii Hort., Manglesia trilobata Hort. ex Ettingsh., and Manglesia cuneata Endl. are outlined and discussed, together with new insights discerned from James Mangles' unpublished Letter Books. The important role of Captain James Mangles R.N. to the botany and horticulture of Grevillea manglesii is reviewed and historical errors are corrected. Manglesia glabrata Lindl. is lectotypified. G. ornithopoda Meisn. is reinstated at specific rank and G. dissectifolia (McGill.) Olde is published as a new combination. Both are phenetically diagnosable without intergrades and occur in discrete populations that sometimes overlap the distribution of related species. [ABSTRACT FROM AUTHOR]

A new rainforest tree species of the myrtle family (Myrtaceae), Syzygium nusatenggaraense Sunarti & Y.W.Low is described here based on two collections from the Lesser Sunda Islands. This species is superficially similar to Syzygium arcanum P.S.Ashton, a Bornean endemic tree species, but differs in a suite of morphological characters and geographic distribution. The new species is illustrated, and description is here given. Satu spesies pohon hutan hujan baru dari suku jambu-jambuan atau Myrtaceae, Syzygium nusatenggaraense Sunarti & Y.W.Low diterbitkan disini berdasarkan kepada dua koleksi dari Kepulauan Nusa Tenggara. Spesies ini mirip dengan satu spesies pohon endemik Borneo Syzygium arcanum P.S.Ashton, tetapi berbeda dalam rangkaian karakter morfologi dan distribusi geografisnya. Spesies baru tersebut diilustrasikan dan deskripsi diberikan di sini. [ABSTRACT FROM AUTHOR]

A new species of Utricularia (Lentibulariaceae) is recognised for north-eastern Western Australia. A description of Utricularia baliboongarnang Baleeiro & R.W.Jobson is provided along with a new circumscription for the Northern Territory species U. singeriana F.Muell. to which it was previously assigned. We also provide comparison with U. hamiltonii F.E.Lloyd, a Northern Territory species for which U. baliboongarnang was recently found to be the phylogenetic sister, and the distantly related western Kimberley species U. byrneana R.W.Jobson & Baleeiro with which it shares a superficially similar corolla. Diagnostic features are illustrated, a taxonomic key containing related species from northern Australia is provided, and distribution, habitat, and conservation status are discussed.

Grevillea gilmourii Olde and G. milleriana Olde, two species new to science, are described. They are putative members of the Aspleniifolia/Hookeriana Subgroup of the Grevillea Pteridifolia Group. Grevillea gilmourii is separated from G. macleayana (McGill) Olde & Marriott where it had previously been treated as the 'Deua form', a geographically disjunct, divided-leaf variant. The separate formal recognition of G. gilmourii here necessitates a revised delineation of G. macleayana to restrict it to populations with undivided leaves only, incorporating recent clarification to terminology in relation to leaf lobing. Grevillea milleriana is a recent discovery from the Maddens Plains area, south of Sydney. Known from a single plant, its recognition as a biological species rather than as a self-sown hybrid is discussed. All three species are linked morphologically and historically to the Victorian species G. barklyana F.Muell. ex Benth., which remains taxonomically unaltered from recent treatments. For the sake of convenience, all four species (G. barklyana, G. macleayana, G. gilmourii and G. milleriana) are grouped informally into an alliance, the Grevillea barklyana alliance, for which diagnostic characters are outlined and two identification keys are given. Both newly described species have divided leaves and are known from only small populations. Conservation recommendations are provided for both new species. [ABSTRACT FROM AUTHOR]
