New distributional record of Lecanorchis nigricans Honda (Orchidaceae) and a new addition for the orchid flora of Indonesia

A new locality of Lecanorchis nigricans from West Java, Indonesia, is reported, and a description based on the Javanese material is provided. Since L. Nigricans was known previously from Japan, Taiwan, Fujian (China) and Thailand, this discovery represents the southern most occurrence of the species. Based on the chasmogamous flowers, spatulate sepals and petals, and cucullate lip, these plants should be L. nigricans var. Yakushimensis among the three varieties of L. nigricans. Considering that species of Lecanorchis are easily overlooked in the wild due to their short flowering season and dwarf habit, L. nigricans may be more widely distributed in Southeast Asia.
