F42AA80873596A63E48D88DDFA67FBDB.taxon	description	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.	en	Bunpha, K., Pedersen, H. Ae., Sridith, K.

Notes — 1. An Oberonia that did not match any species previously recorded for Thailand was collected in 2011 in the northern part of the country, during a field trip with participation of the first author. The material was identified as O. evrardii based on comparison with the protologue and with the holotype in P. We later realized that two earlier collected specimens (one from the same area, one from south-western Thailand) also belong to this species. 2. Oberonia evrardii is here newly recorded for Myanmar, based on a previously misidentified herbarium specimen.	en	Bunpha, K., Pedersen, H. Ae., Sridith, K.

Seidenfaden & Wood 1992), Java (e. g. Comber 1990). Specimens examined.

Notes — 1. During recent revisions of the Thai Oberonia material in BKF and PSU, two previously unrecognized spirit samples of O. gracilis were noted. Together with a plant that was collected in fruit during a recent field trip with participation of the first author, and which subsequently flowered in cultivation, they represent a new national record. 2. Comparison of O. gracilis (as represented by the protologue, the material from Thailand and the drawing of the holotype provided by Seidenfaden 1968: f. 65) with the later O. nitidicauda (as represented by the protologue, an isotype in L and the illustration provided by Smith 1922: t. 31 [III]), we are convinced that the two taxa are conspecific, and we therefore propose O. nitidicauda as a new synonym.	en	Bunpha, K., Pedersen, H.

Seidenfaden & Wood 1992), Java (e. g. Comber 1990). Specimens examined.

Notes — 1. During revision of the Oberonia material in BK, BKF and PSU, two collections of O. microphylla from peninsular Thailand were noted. The older collection (from 2008) had previously been misidentified as O. stenophylla Ridl., whereas the younger collection (from 2009) had been identified as O. rosea by the collectors. 2. Comparison of O. microphylla (as represented by the protologue, the material from Thailand and the illustrations in Smith 1908 – 1914: t. CLXX, Comber 1990: 156) with the younger O. rosea (as represented by the protologue and the drawing provided by Seidenfaden 1968: f. 53), convinced us that the two taxa are conspecific, and we therefore propose O. rosea as a new synonym. We have not examined the type or any other authoritative material of O. kusukusensis, but based on the protologue we believe that X. Chen et al. (2009) were right in considering this taxon conspecific with O. rosea. Consequently, also O. kusukusensis is here proposed as a new synonym of O. microphylla.	en	Bunpha, K., Pedersen, H.

During recent revisions of the Thai Oberonia material in BK and K, we noted that Kerr 500 from northern Thailand, in spite of being traditionally referred to ‘ O. iridifolia (Roxb.) Lindl. ’ (e. g. Seidenfaden 1968, 1978), closely matches O. orbicularis which has not previously been recognized as a member of the Thai flora. 2. Pradhan (1979) treated O. orbicularis as a synonym of O. pachyrachis Rchb. f., a practice adopted by e. g. Pearce & Cribb (2002), whereas X. Chen et al. (2009) placed the former as a synonym of O. obcordata Lindl. However, in line with e. g. Sathish Kumar & Manilal (1994), we prefer to recognize O. orbicularis as a distinct species (Bunpha et al., in prep.).	en	Bunpha, K., Pedersen, H. Ae., Sridith, K.

Distribution — Thailand, Peninsular Malaysia and Singapore (e. g. Seidenfaden & Wood 1992), Sumatra (e. g. Comber 2001), Java (e. g. Comber 1990), Borneo (e. g. Wood & Cribb 1994). Specimen examined. THAILAND, Puudjaa 1803 (BKF), Narathiwat Province, Amphoe Waeng, Bala, 25 Apr. 2012. Notes — 1. A recent collection of this species from peninsular Thailand represents a new national record. 2. Comber (2001) considered the simultaneously described O. polyschista and O. sumatrana conspecific and adopted the former name for the combined species. The holotypes of O. polyschista and O. sumatrana were probably destroyed during the World War II bombing of B, and we have been unable to locate the type of O. flabellifera. However, based on the protologues and on later accounts (e. g. Holttum 1964, Seidenfaden & Wood 1992, Comber 2001), we have little doubt that all three taxa are conspecific with O. stenophylla, and we therefore propose them as new synonyms.	en	Bunpha, K., Pedersen, H.

Notes — 1. The first known Thai collection of this species was made by N. Tetsana and the first author during a field trip in connection with our ongoing revision of Oberonia in Thailand. 2. Oberonia wenzelii is here newly recorded for India. King & Pantling (1898), in their account on the orchids of Sikkim, cited Pantling 185 under O. jenkinsiana Griff. ex Lindl. However, as already suggested by Seidenfaden (1968), ‘ Pantling 185 ’ is confusing. The specimen in K (labelled Sikkim, 1894) matches O. jenkinsiana, whereas we refer the specimens in BM and P to O. wenzelii. In reality, the latter specimens are probably erroneously numbered, as the labels indicate: Engo plateau, 1500 ft. alt., July 1899; i. e. the year after Pantling 185 was cited in King & Pantling (1898). Additional specimens labelled Pantling 185 are deposited in CAL (cf. Ansari & Balakrishnan 1990) and G (cf. Seidenfaden 1968, 1978), but we have had no opportunity to examine them. 3. Oberonia wenzelii is here newly recorded for Myanmar, based on a previously misidentified spirit sample. 4. Oberonia wenzelii is here newly recorded for Java, based on a previously misidentified herbarium specimen.	en	Bunpha, K., Pedersen, H. Ae., Sridith, K.
