BULBOPHYLLUM MINDORENSE 



Bulbophyllum (§Monanthaparva) mindorense Ames in Phi- 

 lipp. Journ. Sci. {Bot.) 2: 334 (1907). 



Rhizome inconspicuous, concealed by the depressed 3-4 mm. 

 long pseudobulbs, which form a continuous sometimes branch- 

 ing chain closely appressed to the bark of trees on which the 

 species is epiphytic. Leaves lanceolate, acute, 6-8 mm. long, up 

 to 3 mm. wide, shortly petiolate. Scapes filiform, up to 4 cm. 

 long. Flower straw-yellow, relatively large, with a very long pe- 

 dicel, apparently without a subtending bract, the pedicel being 

 fully 5 mm. long. Floi^al bract tubular, obliquely truncate. La- 

 teral sepals narrowly lanceolate, acute, 3-nerved, 8 mm. long, 

 2 mm. wide below the middle, margin minutely ciliolate. Upjjer 

 sepal similar to the laterals*, about equally long. Petals linear-ob- 

 long, subspathulate, acute, 1 -nerved, 3 mm. long, about 0.75 mm. 

 wide. Labellum hnear-lanceolate, 3.5 mm. long, about 1 mm. 

 wide. Column 1 mm. long, with a tooth or protuberance in front 

 near the base or below the middle.

 Mt. Halcon, Mindoro, November 27, 1906, E. D. Merrill (no. 5796). 



In the description the lateral sepals are said to be ciliolate on 

 the margin. This statement refers to the minute papillose cells 

 which are visible under the high powers of the dissecting micro- 

 scope. The labellum, as shown in the drawing, is somewhat round- 

 ish at the base, and lightly concave, in general outline linear- 

 lanceolate, and 3-nerved, each of the lateral nerves giving off 

 a branch which runs nearly to the apex of the labellum. The 

 pseudobulbs are as in Bidbophyllum cernuum (Blume) Lindl.
