Aspidistra phongdiensis is described based on the specimen collected from the Thua Thien Hue province of Vietnam. The new species is morphologically similar to A. khangii but differs in wider leaf blade (vs. narrowly elliptic), perigone white outside (vs. purple mottled), yellow pollen (vs. white), introrse anthers (vs. latrorse) and widely obconic pistil (vs. desk-shaped).
Thottea aroangensis T.A. Le, D. Dien & Tagane (Aristolochiaceae) is described based on the specimen collected from the A Roang commune, A Luoi district, Thua Thien Hue province, central Vietnam. This species is characterized by subshrub habit 70–90 cm tall, inflorescence at base of stem close to ground level, campanulate and obscurely lobed perianth ca. 2.6 cm long, inside of perianth tube with creamy white patches, and 20 stamens in 2 whorls, by which combination it is clearly distinguished from the other species of Thottea in Vietnam and its surrounding countries. Morphological descriptions, photographs, a distribution map, vernacular name, and preliminary conservation status are provided for T. aroangensis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
