Thismia Griff. (Thismiaceae), comprises about 35 species. Heretofore, one species was recorded from Kaohsiung County in southern Taiwan. In the course of our botanical inventory, a new species, Thismia huangii P. Y. Jiang et T. H. Hsieh, was collected from northwestern part of the island. Thismia huangii is close to T. rodwayi F. von Muller and T. americana Pfeifer, but can be distinguished from the latter by its orange perianth, dark-orange or red annulus, long hairy connectives, and stigma lobe with one long hair. A taxonomic description, line drawing, pollen morphology in SEM observation, chromosome number, distribution information, and color photographs of the floral characters are provided.
