 n. 1563). 



A remarkable species because of the conspicuous triangular appendage 

 of the stigma, not hitherto described in the genus. In the form of the lip 

 it is nearer to C. variegata Bl. than to C. javanica Bl., but it is much 

 more slender though not so long as in C. stenoglossa Schltr. 



„Leaves very dark velvety purple above, light purple beiieath. Peduncle 

 whitish, the upper half olive brown. Bracts light purple. Ovary light green 

 with brownish green ribs. Sepals base light green, centre watered cinna- 

 mon-brown, apical half Jight saffron. Petals light brimstone-yellow, brownish. 

 at the outer margin and at the base. Column white. Pollinia light yellow". 

 (E. JACOBSON).
