1. Oberonia dissitiflora Ridl.

Oberonia dissitiflora Ridl.(1896) 218. — Type: Ridley s.n. (holo SING), Singapore, Kranji, 10 July 1890.

Oberonia indragiriensis Schltr.(1906) 304. — Type: Schlechter 13306 (holo B n.v.,probably destroyed), Sumatra, Riau,Indragiri,Danau Kotta, May 1904.

Oberonia indragiriensis Schltr.var. javanica J.J.Sm.(1921) 266. — Type: Bakhuizen van den Brink s.n. (not located), Java, Jawa Barat, Bogor, Tjiomas, flowering in cultivation April 1920.

Occurrence in Thailand — Central (Nakhon Nayok); South-western (Uthai Thani) .

Distribution — Thailand, Peninsular Malaysia (e.g. Seidenfaden & Wood 1992), Singapore (e.g. Ridley 1896), Sumatra (e.g. Comber 2001), Java (e.g. Comber 1990).

Specimens examined. THAILAND, Buakhlai 100 ( BCU), Nakhon Nayok Province, Khao Yai National Park, Khao Khiao , c. 600 m alt., 15 Oct. 2005 ; Srisom 18 ( BKF), Uthai Thani Province, Huai Kha Khaeng Wildlife Sanctuary , 26 Oct. 2012 .

Notes — 1. Examination of the Oberonia material in BCU revealed a previously misidentified specimen of O. dissitiflora from central Thailand, and in 2012 this was followed by a new collection from the south-western part of the country. In contrast, a previous report of O. dissitiflora from Thailand ( Comber 1990) appears to be unsubstantiated, for which reason we consider the two recent collections to represent the first confirmed Thai record.

2. The holotype of O. indragiriensis was probably lost during the World War II bombing of B, and we have not been able to locate the type of O. indragiriensis var. javanica . However, based on the protologues, we agree with Holttum (1964) that O. indragiriensis s.l. is probably conspecific with O. dissitiflora .
