Abstract
Three species of the genus Hoya (Apocynaceae, Asclepiadoideae) are newly reported for the flora of Vietnam. One species, Hoya honglenae, is described and illustrated as new to science, and two species, H. acuminata and H. phuwuaensis, are reported as new national records known earlier, respectively, in Bhutan, Bangladesh, NE India, W China, Myanmar; and NE Thailand. The new species discovered in Phu Quoc Island (Kien Giang Province) morphologically is most close to H. phuwuaensis, but differs in the entire, straight leaf margin, leaves sparsely white speckled adaxially and dirty purple speckled abaxially, smaller yellow flowers, conoid, obtuse, distally up-cured outer angle of corona lobes, and much longer anther appendages. The paper provides morphological descriptions, data on habitat, phenology, distribution, estimated conservation status, taxonomic notes, a list of studied specimens, and color illustrations for all studied species. Taking into consideration our new data, the genus in Vietnam currently includes 44 species.
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.
