ORCHIDACEM 



99 



obtuse, recurved, fleshy, smooth, about 2 lines long. Column 

 stout and very short, with a pair of short subulate teeth. — On 

 Mt. Mariveles, in the Province of Bataan, Merrill, n. 3720. An ally 

 of the Javan B. gibhosum, Lindl. (Gen. & Sp. Orch. p. 54), 

 which has a shorter inflorescence, more acuminate sepals, and the 

 petals also acuminate and not thickened at the apex. The flowers 

 of B. dasypetalum appear to have been greenish-yellow when 

 alive." — R. A. Rolfe in MS. 



Rhizome creeping, about 2 mm. thick, emitting at intervals 

 long fibrous roots. Pseudobulbs none, or only indicated by swell- 

 ings of the rhizome. Petiole 6-8 

 cm. long, lamina oblong, acute, co- 

 riaceous, 13 cm. long, about 2.5 

 cm. wide. Scape equalling or ex- 

 ceeding the leaf, slender, bearing 

 a simple raceme of short-pedicelled 

 yellowish fragrant flowers. Basal 

 bracts elongated, tubular with a 

 spreading acute tip. Floral bracts 

 exceeding the ovary, lanceolate, 

 acute, about 4 mm. long. Perianth 

 about 6 mm. long, slightly spread- 

 ing. Lateral sepals deltoid-lanceo- 

 late, acuminate, acute, 3-nerved. 

 Upper sepal oblong -lanceolate, 

 smaller than the laterals. Petals 

 3 mm. long, 1-nerved, oblong, 

 constricted near, and thickened 

 at, the apex. Lip tongue-shaped, 

 obtuse; claw deflexed at right 

 angles to the lamina ; margins connivent. Column minute. 



No. 3719, Merrill, collected at the same time as the type, is 

 perhaps only a variety with shorter leaves, the flowers smaller, 

 with the petals scarcely thickened near the apex.
