ORCHIDACE.E 



tion, three-nerved. Dorsal sepal very similar, about 2.25 cm. 

 long, 3 mm. wide at the base. Petals similar to the sepals but 

 smaller, about 1.6 cm. long, 1.9 mm. wide below, oblong-lance- 

 olate with very long caudate apex, lower margins hyaline erose, 

 one-nerved. Lip in natural position strongly decurved, when ex- 

 tended about 5.2 mm. long, 2.2 mm. broad at the base, narrowly 

 lanceolate, acuminate, the center longitudinally thickened and 

 provided with a pair of approximate keels which originate in 

 unciform-decurved lamellae near the base and extend nearly to 

 the apex where they fuse. Column about 2.5 mm. long, short 

 and stout, provided with three teeth, an acute broadly triangu- 

 lar central tooth and a pair of triangular arms which terminate 

 in subulate teeth. Foot stout, upcurving. 



This species is allied to Bulbophyllum Jarense Ames and 

 B. penduUscapum J. J. Sm., but it possesses narrower leaves and 

 looser racemes of larger flowers. Unlike B. Korthalm Schltr. 

 and B. leptosepalum Hook, f., this plant has prominent though 

 sheathed pseudobulbs and long caudate petals. B. disjunctum 

 differs from B. Stella Ridl. in the very loose racemes, promi- 

 nent bracts and caudate petals. The conspicuous floral bracts, 

 spreading perianth and simple lip distinguish this species from 

 B. cleistogamum Ridl. B. hamatifolium J. J. Sm. lacks the dis- 

 tinct pseudobulbs, long caudate petals and simple lip.
