Chamaelirium Shimentaiense (Melanthiaceae), A New Species From Guangdong, China

Chamaelirium shimentaiense (Melanthiaceae), a new species from Shimentai Nature Reserve, Guangdong Province, China is described. This species is similar to C. shiwandashanense and C. viridiflorum in having actinomorphic flowers with six tepals and unilocular anthers, but is easily distinguished from them by its strongly undulate leaf blades with crispulate margins and inconspicuous venation, purplish tepals with a slightly broadened and obtuse apex, and purple-tinged filaments. The infrageneric assignment of this species is discussed and a color plate is provided.
