ORCHIDACEiE 



mate, cylindric, closely striate in the dried specimen, monophyl- 

 lous, invested by sheaths that become fibrous. Leaf about 12 cm. 

 long, 3 cm. broad, elliptic-oblong, appearing acute at the imper- 

 fect complicate apex, cuneately narrowed to a sulcate petiole 

 about 3.5 cm. long, coriaceous, many-nerved with the mid-nerve 

 sulcate above and carinate beneath. Scape approximate to the 

 pseudobulbs, suberect-flexuous, about 22 cm. tall up to the ra- 

 ceme, 1.5 mm. thick, terete below, striate above in the dried 

 specimen, provided with two small remote tubular appressed 

 scarious sheaths. Rachis sharply reflexed, blackish-brown, gla- 

 brous. Raceme very dense, about 4.7 cm. long, 7 mm. broad. 

 Bracts minute, about .6 mm. long, less than half the length of 

 the pedicellate ovary. Flowers very small, glabrous. Lateral 

 sepals about 4-4.2 mm. long, 2 mm. broad at the base and a little 

 wider across the middle, ovate-falcate and decurved,very oblique, 

 obliquely rounded to a subacute apex, three-nerved, somewhat 

 ciholate. Dorsal sepal about 3.5-4 mm. long, 3.2 mm. wide at the 

 base, triangular, acute or obtuse, strongly concave, ciliate espe- 

 cially above, revolute at the apex. Petals about 3.1 mm. long, 

 1 mm. wide, lanceolate, long acuminate to a caudate apex, mark- 

 edly ciliate on the anterior half, one-nerved. Lip strongly de- 

 curved below the middle, when expanded ovate, about 2-3 mm. 

 long, 1.75-2 mm. broad, very fleshy and densely papillose, apex 

 obtuse or subacute, ciliate, channeled in the middle toward the 

 base, margins revolute, the central area on the under surface 

 thickened and medianly channeled. Column minute, furnished 

 above with a central fleshy suborbicular tooth and a conspicuous 

 pair of parallel arms which rise as subulate points from irregular 

 basal dilations. Column foot short, stout, arcuate. 



The nearest relative of this plant is Bulbophyllum Merrittii 

 Ames, from which it varies in having wider sepals, far different
