ORCHIDACEM 



with rufous bracts. Floral bracts sheatbing at base, then spread- 

 ing, concave, broadly ovate, acute, longer than the ovary. Lateral 



sepals sub-erect, oblong-lanceolate, 

 sub-acute, 5 mm. long, 2 mm. 

 wide, united basally, gibbous, 

 forming a sac which is grooved 

 and blunt. Upper sepal lanceolate, 

 obtuse, 5 mm. long. Petals linear- 

 lanceolate, sub-acute, 3-nerved, 

 tapering gradually from base to 

 apex, 5 mm. long, 1 mm. wide. 

 Labellum entire ; blade lanceolate 

 to ovate-lanceolate, thickened on 

 the apical half, 3-nerved, sub-acute, 

 4 mm. long; claw strongly de- 

 flexed, then shortly ascending to 

 the foot of the column. Column 

 exalate, expanded above into the 

 two round lobules of the cHnan- 

 drium, narrowed below into a dis- 

 tinct foot. Pollinia broadly pyri- 

 form. — A most unattractive plant, which appears to be made up 

 of confused leaves and imbricate, rust-colored bracts. From dried 

 specimens it seems to be a decumbent or prostrate diffuse epiphyte 

 with coriaceous leaves.
