Nilghiri in flower only. The ripe fruit of the Andaman species is 1 in. long. The 

 Ceylon one has much shorter points to the leaves, but the fruit is as large as m 

 Blume's figure. Blume distinguishes 0. assamica by the column being as long as the 

 capsule ; which they are in typical veratrifoUa.

 flowers l|-2 in. long, sepals very slender -vyith very narrow blades, petals

 1 in. long, sepals narrowly oblanceolate, petals oblanceolate crenate, blade 

 of lip triangular-ovate acuminate, ribs of fruit strong wrinkled. 



Pebak, ScortecMni, King's Collector, Wray. 



Stem 4 ft. high and leaves as in C. veratrifoUa, from which the broader petals, 

 form of the lip, and deeply ridged fruit 1-li in. long with wrinkled ribs 

 distinguish it. Column long.

 petioled, column -^ in. long.
