ORCHIDACE.E 



Petals about 1.5 cm. long, 5 mm. broad, oblong, oblique, sub- 

 falcate, acute and dorsally carinate at the apex, five-nerved. Lip 

 raised on a stout unciform stipe, about 7.5 mm. long, narrowly 

 triangular-cordate, strongly decurved, very fleshy particularly 

 down the middle, the center channeled near the base, apex 

 broadly obtuse, lower margins thin and denticulate. Column very 

 short and stout, about 3 mm. long and somewhat broader, pro- 

 vided above with a pair of parallel, porrect, unciform-spatulate, 

 decurved arms which are about 2.6 mm. long. Column foot stout, 

 about 6 mm. in length along the union with the petals ; unci- 

 form portion free, about 3 mm. long. 



This plant has three rather close relations, Bulbophyllum 

 cornutum Reichb. f., H. memhranifolium Hook. f. and B. phae- 

 anthum Schltr. The first species has a much shorter scape than 

 B. concavum, flat dorsal sepal and conspicuous divergent side 

 lobes to the lip. B. meinbranifoUum has longer leaves, naked 

 pseudobulbs and truncate base to the lip. B. phaeanthum differs 

 from the Kinabalu plant in its smaller sepals, apiculate sepals 

 and petals and larger lip.
