Abstract

Aspidistra thuongiana is described and illustrated as a new species from the South Central Coast region of Vietnam. The new species has bright yellow flower and a slender pistil with a minute stigma. It is morphologically close to A. longipedunculata, but differs in shorter peduncle, bowl-shaped (vs. campanulate) perigone, shorter ovate (vs. oblong) erect to spreading (vs. recurved) perigone lobes and stamens inserted at the base (vs. middle) of perigone tube. Data on nuclear 5S-NTS region of the new species are provided, aimed to serve as a molecular characterization for comparison with its congeners.
