7. Oberonia orbicularis Hook. f.

Oberonia orbicularis Hook.f. (1886–1890) 677 [publ. 1888]. — Iridorkis orbicularis (Hook.f.) Kuntze (1891) View in CoL 669. — Type: Clarke 9610 (holo K), India, Sikkim, Dikkeeling , c. 915 m alt., 12 Oct. 1819.

Occurrence in Thailand — Northern (Chiang Mai). Distribution — Sikkim (e.g. Seidenfaden 1968), Thailand.

Specimen examined. THAILAND, Kerr 500 ( BK, K), Chiang Mai Province ,

Mae Samoeng, c. 700 m alt., 21 Oct. 1922.

Notes — 1. 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.).
