Abstract

Didymoplexis micradenia (Rchb. f.) Hemsl. was recently found to be a new record of Didymoplexis Griffith in Taiwan. It is similar to D. pallens Griff. except that it is characterized by a smaller flower, very short column foot, and lip apical margin that is minutely denticulate. The description and illustration of D. micradenia and a key of Didymoplexis in Taiwan are provided in the present work.
