Abstract

Diospyros adinandrifolia, a new species of Diospyros (Ebenaceae) from southeast Yunnan, China, is described and photographed. Photographs of type specimens and ecological information are provided. Diospyros adinandrifolia resembles D. undulata in its elliptic leaves, clustered flowers, and synsepalous calyces, but differs by abaxial leaf base without glands, calyx without obvious lobes and the fruiting calyx being not reflexed during maturation. It is also morphologically similar to D. dussaudii in buds shape and inflorescence morphology, but differs in its leaves being white pubescent when young and glabrescent, paniculate male inflorescences, and succulent fruit. Based on the examination of the specimens from China and Vietnam, the species is categorized as Endangered (EN) according to the IUCN Red List criteria.

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
