Heteropolygonatum wugongshanensis (Asparagaceae, Polygonateae), a new species from Jiangxi province of China

Heteropolygonatum wugongshanensis, a new species from tribe Polygonateae in subfamily Nolinoideae (Asparagaceae) from Jiangxi Province of China, is described and illustrated. The placement of this species within Heteropolygonatum is assessed based on morphological comparisons, chromosomal evidence and molecular phylogenetic analyses. The new species is morphologically and phylogenetically related to H. roseolum, but differs from it by stems 10-20 cm tall, leaves 3-5, 12-14-nerved with prominent midrib, perigone campanulate whitish-purple, tipped greenish. The chromosome number of the H. wugongshanensis is 2n = 32 = 20m + 2sm + 10st and its karyotypes is asymmetrical with a high proportion of meta-centric and submetacentric chromosomes.
