ORCHIDACE.E 



late, sharply mucronate, very oblique, forming a saccate men- 

 turn, indistinctly three-nerved. Dorsal sepal apparently smaller, 

 about 3.5 mm. long, 1.5 mm. wide near the base, lanceolate, mu- 

 cronate, concave, indistinctly three-nerved. Petals about 3 mm. 

 long, 1 mm. wide, ligulate, broadly rounded at the apex, apic- 

 ulate, indistinctly three-nerved. Lip in natural position folded 

 against the column and enclosed by the mentum of the lateral se- 

 pals, concave-involute, when expanded about 4 mm. long, 2. 4 mm. 

 wide, ovate-oblong, broadly rounded above ; anterior portion pro- 

 vided with a broad transverse bilobed plate which on the poste- 

 rior margin is barbed with long slender hairs, and above the sinus 

 of the plate there is a slender papilliform tubercle ; from the base 

 of the lip to the plate runs a stout, median keel. Column about 

 1.75 mm. long, stout, with four sharp teeth, the central pair of 

 which are longer than the lateral ones ; foot broad, membrana- 

 ceous. 



Many variations are manifest in this species ; Clemens 61 shows 

 floral characteristics that approach those of Chilopogon Mer- 

 rillii Ames, especially in having petals which are slightly spatu- 

 late, and Clemens 348 shows small, very delicate plants. 



This species differs from the very nearly allied Chilopogon 



Merrillii Ames in the broader truncate and mucronate floral 



bracts, the smaller petals, the longer pair of central teeth on the 



column and the color of the flowers. (Plate 93.)
