Peliosanthes epigynica (Asparagaceae, Convallarioideae), a new species from southeastern Vietnam

Peliosanthes epigynica, a new species occurring in a dry coastal forest in southeastern Vietnam (Ninh Thuan Province) is described and illustrated. It is distinguishable from any other Peliosanthes by a combination of the following character states: comparatively small elliptic leaf blades, drooping narrowly campanulate purple/violet flowers, and a nearly flat-topped, perfectly inferior ovary with a short straight (non-tortuous) conoid style. Besides data on morphological and ecological aspects, we provide notes on its taxonomic relationships to some other species similarly sharing completely epigynous flowers.
