12. Oberonia wenzelii Ames

Oberonia wenzelii Ames (1915) 77. — Type: Wenzel 0388 (holo AMES,photo seen), Philippines, Island of Leyte, Jaro , 30 Apr. 1914.

Oberonia jenkinsiana auct. non Griff.ex Lindl.: Seidenfaden (1968) 108 p. p., f. 75.

Occurrence in Thailand — Peninsular (Phangnga). Distribution — India (Note 2), Myanmar (Note 3), Thailand,

Java (Note 4), Philippines (e.g. Valmayor 1984).

Specimens examined. INDIA, Pantling 185 ( BM, P; both probably misnum- bered), West Bengal, Darjeeling District, Engo plateau, c. 460 m alt., July 1899 . – INDONESIA, Java, sine coll./ Herb. Mus. Paris P 00364399 (P), sine loco et anno. – MYANMAR, Rule 5349 (K), sine loco, 14 Oct. 1961 , flowering in cultivation 21 May 1962. – THAILAND, Tetsana & Bunpha 397-2 ( PSU), Phangnga Province, Amphoe Takua Pa, Sri Phang Nga National Park , Namtok Tam Nang , 26 Dec. 2011 .

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.
