2. B. wallichii Reichenbach (1861: 259). (Fig. 1). Type:— NEPAL. 1832, Wall. Cat. n. 1980 (K000894326 photo!). ≡ Cirrhopetalum wallichii Lindley (1839: 72), non Wallich (1830: 51). ≡ Tripudianthes wallichii (Reichenbach) Szlachetko & Kras (2007: 96). ≡ Bulbophyllum refractoides Seidenfaden (1970: 342), nom. superfluum. Habitat and phenology: —Epiphyte on tall trees in evergreen broad-leaved forest. Distribution: — Vietnam (Lam Dong Province), Nepal, NE India, Myanmar, China, Thailand, Laos. Proposed conservation status:—According to currently available data, B. wallichii is found only in one location as a clustering epiphyte on tall tree in primary broad-leaved forest in Lam Dong Province. There is no direct threat to this habitat. Hence the species can be assessed in Vietnam as Vulnerable based on small AOO, VU D2. Meanwhile, there is insufficient data for global distribution area of this specie where its conservation status should be identified as Data Deficient (DD). Note:— Seidenfaden (1970: 342) considered the collection, Tixier 15 (P00348218) as Bulbophyllum refractoides, which is currently accepted as a synonym of B. wallichii. However, the line drawing of Tixier on the herbarium sheet clearly shows the dorsal sepal with stiff hairs on inner surface and on the margin (not fimbriate as in B. wallichii). We suspect the identification of this specimen may be incorrect. Meanwhile, additional specimens of the true B. wallichii were recently collected in Vietnam, in Lam Dong Province. These collections are presently confirmed by the voucher specimens (BV 1483, 1484) stored at LE (LE01169312! & LE01169312!) and VNM (VNM00043086!) Herbaria. At the same time, the specimen from NE India collected by Hooker and Thomson (P00362039) seem different from the type in a longer dorsal sepal with acuminate (not caudate) apex, and may represent separate variety or even species; which require detailed study. Studied specimens: — VIETNAM, Lam Dong Province, 14 December 2021, Truong Ba Vuong & Nguyen Phi Tam, BV ...
