ORCHIDACE^ 



iform callus extends from near the base to about the center of 

 each lateral margin which it contracts. Column very short fleshy 

 dilated, provided above with a prominent semiorbicular dentate 

 rostellum and a shallowly bilobed androclinium, and below with 

 a prominent unciform foot. 



There appear to be several species more or less allied to this 

 plant. Appendicula muquilingensis Ames has shorter leaves and 

 very different lip. The narrowly proportioned leaves and dissim- 

 ilar floral characters separate it from A, pendula Bl. and^. un- 

 cata Ridl., while A. dendrobioides Schltr. varies chiefly in its 

 shorter broader leaves and larger flowers.
