ORCHIDACE.©. 389 



rostellum, covered by a hood. Polliniums four, cohering 

 in pairs by short granular caudicles. 



The annual tuberous sections, each ending ultimately in a 

 flower, are sufficient to distinguish Coelogyne from all our other 

 orchids except Spiranthes and Cheirostylis, which are ground 

 plants. Though formed every year, the sections and their 

 leaves are perennial, and remain green for many years. 



Species 50 to 70. All in India and the Malay Islands. This 

 genus has furnished some of our most beautiful cultivated 

 orchids.
