ORCHIDACE.E 



rigid, subcoriaceous, the mid-nerve sulcate above and carinate 

 beneath, obliquely spreading from the rhizome. Scapes much 

 surpassing the leaves, ±10 cm. long, ascending-spreading, rising 

 from the bases of the pseudobulbs or from the rhizome midway 

 between the pseudobulbs, clothed at the base with several closely 

 imbricating scarious sheaths and above with about two remote 

 slender tubular scarious sheaths. Raceme loosely flowered. 

 Bracts of the inflorescence mostly deciduous, lance-attenuate, 

 scarious. Flowers small. Perianth pellucid in the dried specimen, 

 sepals with spreading caudate tips. Lateral sepals about 7 mm. 

 long, 3 mm. wide, broadly triangular below, oblique, forming 

 a saccate mentum, indistinctly three-nerved, terminating in a 

 rather abrupt slender cauda which is about 4.5 mm. long. Dorsal 

 sepal about 6 mm. long, 1.5 mm. broad at the base, lanceolate 

 with a long caudate apex, concave at the base, one- or indistinctly 

 three-nerved. Petals minute, about 1.55 mm. long, 1.2 mm. 

 broad at the base, ovate, acute, one-nerved. Lip minutely clawed, 

 in natural position decurved with the sides of the lower portion 

 erect and conduplicate, the sides of the anterior part strongly 

 reflexed, with the upper surface convex ; lamina when expanded 

 oblong, simple, obtuse or subacute, about 3.5 mm. long, 1.4? mm. 

 wide, the lower portion of the under surface conspicuously 

 carinate-thickened in the median line. Column very minute, 

 furnished with a foot that is thickened below and unciform 

 above. 



This unusual species closely resembles BuJbophyllum philip- 

 pinense Ames in habit and foliage, but differs from it in having 

 smaller pseudobulbs, relatively elongate loosely flowered scapes 

 and larger flowers. In habit it resembles B. longerepens Ridl., 

 but possesses much smaller pseudobulbs, larger leaves, different 

 petals and lip.
