    [Botany • 2022] Tupistra thangii (Asparagaceae) • A New Species from southern Vietnam

     

    Tupistra thangii N.Tanaka & D.D.Nguyen,

    in D. D. Nguyen, V. C. Nguyen et Tanaka, 2022. 

    Abstract
    Tupistra thangii, a new species from Lam Dong Province, southern Vietnam, is described and illustrated. It is most similar to T. clarkei from eastern Nepal and northeastern India, but differs mainly in its broader leaves, upright or ascending spike, smaller flowers, laterally strongly revolute perianth lobes, stamens adnate to the subbasal portion of the perianth lobes, and whitish stigma. It also shares some key traits (e.g. internally white-striped, dark purple perianth tube) with T. natmataungensis from western Myanmar. Notes on the phenology, habitat, distribution and taxonomic relationships to several similar species are also provided.

    [Botany • 2024] Reinstatement and Lectotypification of Phyllanthus rosellus (Phyllanthaceae), an endemic species from the State of Minas Gerais, Brazil


    Phyllanthus rosellus  (Müll.Arg.) Müll.Arg.

    in Torres et Silva, 2024. 

    Abstract
    Phyllanthus rosellus, an endemic species from the state of Minas Gerais, Brazil, was treated under Phyllanthus niruri subsp. lathyroides. After analyzing herbarium collections, including all types related to the names P. niruri and P. rosellus, we conclude that both species are morphologically distinguishable, and consequently we propose the reinstatement of P. rosellus. Additionally, as the latter is a species usually known from literature dating from the 19th century, where its description overlaps with that of some congeners, we provide its description, illustrations, preliminary conservation status, images in their habitat, as well as designate a lectotype for it.

    [Botany • 2018] Sciaphila lambirensis (Triuridaceae) • A new mycoheterotrophic plant from Sarawak, Borneo, Malaysia

     

    Sciaphila lambirensis Suetsugu, 

    in Suetsugu. 2018.  

    Borneo is known to harbor the greatest species diversity of the mycoheterotrophic genus Sciaphila (Triuridaceae) and is home to 11 species, including five endemics. Here, another undescribed Sciaphila species, Sciaphila lambirensis, which was discovered during a botanical survey in Lambir Hills National Park (Sarawak, Borneo, Malaysia) is reported along with a detailed morphological account. Sciaphila lambirensis is similar to S. brevistyla in having six equal perianth segments with a swollen apex bearing long hairs in both staminate and carpellate flowers. However, it is easily distinguishable by the secund arrangement of the flowers and the pedicel slightly recurved at its apex. A key to the species of Sciaphila in Borneo is provided.

    [Funga • 2022] Phaeoclavulina aeruginea & P. cinnamomea (Gomphales: Gomphaceae) • Two New Species from Hunan Province, China

    Phaeoclavulina aeruginea P. Zhang,  
    P. cinnamomea W.Q. Qin, 

    in Liu, Yan, Deng, Qin et Zhang, 2022. 

    Abstract
    Two new species of Phaeoclavulina (Gomphaceae, Gomphales, Basidiomycota) from Hunan Province, China are distinguished on the basis of the morphological characters and molecular phylogenetic analyses. Phaeoclavulina aeruginea is characterized by basidiomata ramarioid, repeatedly branched, stipe yellowish brown, copper-green and blunt branch tips, and the context, turning wine red when bruised or exposed. Phaeoclavulina cinnamomea produces the cinnamon basidiomata, crowded branches, and large basidiospores with truncate (volcanic) spines, which is particularly rare in Phaeoclavulina. The two species are illustrated by drawings and photographs, including scanning electron micrographs. Their taxonomic distinctness was supported by the phylogenetic analyses of internal transcribed spacer (ITS) and nuclear ribosomal large subunit (nrLSU) sequence data. The ITS and nrLSU sequences newly generated in this study were deposited in GenBank. A key to Phaeoclavulina species in China is provided.

    [c] Basidiomata, bar = 2 cm; [d] Branch tips, bar = 0.25 cm.  

    Phaeoclavulina aeruginea P. Zhang, sp. nov.

    Etymology:—Aeruginea (Lat.): refers to the distinctive copper-green color of the tips of the basidiomata branches.

    Phaeoclavulina cinnamomea W.Q. Qin, sp. nov.

    Etymology:—Cinnamomea (Lat.): refers to the pinkish cinnamon color of the basidiomata surface.
