4. B. refractum (Zollinger 1847: 456) Reichenbach (1861: 259), Seidenfaden (1970: 347), Averyanov (1994: 284), Seidenfaden (1992: 263). (Fig. 4). ≡ Cirrhopetalum refractum Zollinger 1847: 456. Type:— INDONESIA. Java, Zollinger, 2261 (G00165064 photo!). ≡ Phyllorkis refracta (Zollinger 1847: 456) Kuntze (1891: 677). ≡ Tripudianthes refracta (Zollinger 1847: 456) Szlachetko & Kras (2007: 96). Habitat and phenology: —Epiphyte on tall trees in primary evergreen broad-leaved forests. Flowering observed in December–February. Distribution: — Vietnam (Lam Dong, Gia Lai, Dak Nong, Binh Phuoc, Dien Bien provinces), Bhutan, India, Myanmar, Thailand, Java and Sumatra. Proposed conservation status:—According to currently available data, B. refractum seems quite common in Vietnam. Due to attractive nature of flowers, the species is widely collected for trade. Based on the national EOO 148,826.741 km 2 and AOO 28.000 km 2, and in accordance with IUCN criteria (IUCN, 2022), the species should be assessed in Vietnam as VU B2ab(v). The verifiable data for this species’ conservation status outside Vietnam is not available. Note:—Common in Vietnam, with relatively large flowers having a large dorsal sepal. The species is sometime misidentified as B. kanburiense; the main differences is indicated under the note for B. kanburiense. The drawing of Pham Hoang Ho (1992: 844) named as B. refractum possibly based on specimens of Tixier 15 (P 00348218) having a very small dorsal sepal typical for B. wallichii.
