ABSTRACT The Ebenaceae of Cambodia, Laos, and Vietnam have yet to be treated in the ongoing Flora projects. The first step towards an updated account is the resolution of the nomenclatural status of the taxa known to occur in the region. Here we designate lectotypes for 50 taxa described by Lecomte between 1925-1930. We also provide currently accepted names for these species.

ABSTRACT Five new species of Urophyllum Wall. endemic to Cambodia and Viêtnam are herein described and illustrated, and U. annamense (Pierre ex Pit.) Yooprasert, Culham & Utteridge, stat. nov. is raised to species status. The new species are unique due to the morphological combination of indumentum, secondary venation, stipule shape and inflorescence structure as follows: U. bidoupense Yooprasert, Culham & Utteridge, sp. nov.: plant almost glabrous, secondary veins weakly brochidodromous, stipule glabrous, oblong-lanceolate; U. chinense subsp. latistipulum Yooprasert, Culham, Yahara & Utteridge, subsp. nov.: similar appearance to the U. bidoupense but differs with stipule ovate to elliptic, hairy along the midline; U. brochidodromum Yooprasert, Culham & Utteridge, sp. nov.: stem and branches hairy, adaxial leaf surface hairy on midrib and secondary veins, secondary veins conspicuously brochidodromous, stipule hairy, lanceolate; U. pulchristipulum Yooprasert, Culham & Utteridge, sp. nov.: plant glabrous, secondary veins festooned brochidodromous, stipule glabrous and subcordate, inflorescence sessile; U. pseudoschmidtii Yooprasert, Culham, Yahara, Tagane & Utteridge, sp. nov.: stem and branches hairy to subglabrous, secondary veins festooned brochidodromous, stipule sparsely to densely hairy, linear-lanceolate to oblong-lanceolate, pistillate flower with no staminodes. An identification key to Urophyllum species of Cambodia, Laos and Viêtnam is provided. Point occurrence maps are presented for each species, as well as provisional conservation assessments based on IUCN guidelines.

ABSTRACT Succulent angiosperm plants are characterized by the presence of large amounts of water storage tissue as an adaptation to habitats where water is unavailable seasonally or in microhabitats where water is of limited access. In this study, I describe the anatomy of stem and caudex of ten species of succulent plants from eight plant families in the Rosids clade. There are two characteristics of wood among all species with single continuous cambium or successive cambium: 1) extensive parenchyma tissue in ray system and/or axial system; and 2) extensive thin-walled fiber tissue in the axial system. Out of ten species, five present proliferation of the parenchyma tissue in their radial system: Ceropegia africana R. Br., Momordica rostrata Zimm., Oxalis megalorrhiza Jacq., Adenia glauca Schinz and Cyphostemma juttae (Dinter & Gilg) Desc. Five species were fibrous-wood succulents: Jatropha curcas L., J. macrantha Müll. Arg., Adenium obesum (Forssk.) Roem. & Schult., Pelargonium carnosum (L.) L'Hér. and Moringa drouhardii Jum. Out of ten, one presents an axial system without visible fibers: Cyphostemma juttae (Dinter & Gilg) Desc. Despite to belong to seven different orders, the studied species show structural similarity: extensive parenchyma in the ray system and thin-walled fibers in the axial system. These results suggest multiple independent origins for the anatomical structure of succulence.

RÉSUMÉ Deux nouvelles espèces de Cynorkis Thouars (Orchidaceae) du nord de Madagascar, C. windsorensis Hervouet, sp. nov. et C. ankaranensis Hervouet, sp. nov. sont décrites. Par ailleurs Cynorkis tryphioides var. leandriana (H.Perrier) Bosser est élevée au rang d'espèce sous le nom Cynorkis leandriana (H.Perrier) Hervouet, comb. nov., stat. nov. Les deux nouvelles espèces correspondent à des spécimens conservés au Muséum national d'Histoire naturelle. Elles sont toutes deux lithophytes alors que Cynorkis tryphioides Schltr. est terrestre. Cynorkis windsorensis Hervouet, sp. nov. se distingue de Cynorkis tryphioides Schltr. par sa plus grande taille, ses feuilles sub-orbiculaires tesselées, un découpage du labelle différent et une coloration différente des fleurs. Cynorkis ankaranensis Hervouet, sp. nov. a des fleurs semblables à celles de Cynorkis windsorensis Hervouet, sp. nov. mais plus nombreuses, c'est une plante plus grande, aux grandes feuilles ovales, vert uni et très brillantes. Enfin Cynorkis tryphioides var. leandriana (H.Perrier) Bosser, dont le basionyme est Benthamia leandriana H. Perrier, présente de nombreux caractères différents (taille, feuilles, fleurs, biotope) de la variété typique Cynorkis tryphioides Schltr. et est, par conséquent, élevée au rang d'espèce. Elle se distingue des autres espèces citées ici par ses fleurs blanches et son port, avec une inflorescence bien plus grande relativement à la longueur des feuilles. Sa seule station connue, le Tsingy du Bemaraha, est de plus très éloignée du nord de Madagascar, où se trouvent tous les autres taxons de ce complexe.

ABSTRACT Most species of the genus Cynorkis are found on the Western Indian Ocean Islands. The correct taxonomic status of many species in this genus is not clear or is unresolved due to poor or lost type specimens, coupled with short protologue descriptions. Here, we lectotypify Cynorkis coccinelloides (Frapp.) Schltr. and show that C. brachycentra (A.Rich.) ex. Kraenzl.is a synonym of C. trilinguis (Frapp.) Schltr.. Moreover, C. flexuosatis (Thouars) Hermans, a Mauritian endemic, and C. trilinguis, a Réunion endemic, are different species. These clarifications are important to correct the taxonomic reference for the Mascarene flora, and to support any necessary conservation work.

ABSTRACT Assessing the genetic diversity of species and populations is critical for evaluating extinction vulnerability and provides important information for identifying populations of concern and/or those that should be targeted for breeding material. Baobabs (Adansonia L.) are botanical icons for conservation, with increasing attention regarding their threatened status from both scientists and non-scientists alike. Baobabs are of particular interest especially in Madagascar, where six of the eight species are endemic, and three are listed as Endangered or Critically Endangered by the International Union for Conservation of Nature (IUCN). Although A. madagascariensis Baill., A. rubrostipa Jum. & H. Perrier and A. za Baill. are more widespread and classified by IUCN as Least Concern, they show regional variation, which may reflect hidden genetic diversity or even the existence of cryptic species. Here we assess the genetic diversity of the Malagasy baobabs to serve as a basis for future conservation and management planning. Our study used a targeted sequence capture approach (hybrid enrichment) to obtain hundreds of low-copy nuclear loci with phased alleles to assess genetic diversity in the six species and their major regional subpopulations. We discuss the implications of proper delineation of species taxonomy for management issues associated with conservation. We hope such genetic information will guide more targeted population genetic assessments and inform conservation and management efforts, including identification of isolated or disjunct populations that may warrant targeted actions.
评估物种和种群的遗传多样性对于评估灭绝脆弱性至关重要，并为确定关注种群和/或应作为育种材料目标的种群提供重要信息。猴面包树(猴面包树)是植物保护的标志，越来越受到科学家和非科学家的关注。猴面包树在马达加斯加尤其引人注目，8种猴面包树中有6种是当地特有的，其中3种被国际自然保护联盟(IUCN)列为濒危或极度濒危物种。尽管A. madagascar。A. rubrostipa Jum;& H. Perrier和A. za Baill。分布较广，被IUCN列为“最不受关注”(Least Concern)的物种，它们表现出区域差异，这可能反映了隐藏的遗传多样性，甚至是隐藏物种的存在。在此，我们评估了马达加斯加猴面包树的遗传多样性，作为未来保护和管理规划的基础。本研究采用靶向序列捕获方法(杂交富集)获得了数百个具有阶段性等位基因的低拷贝核位点，以评估6个物种及其主要区域亚群的遗传多样性。我们讨论了物种分类的正确界定对保护相关管理问题的意义。我们希望这些遗传信息将指导更有针对性的种群遗传评估，并为保护和管理工作提供信息，包括确定可能需要采取有针对性行动的孤立或分离种群。
