NOTES ON COELOGYNE 



By T. D. a. Cockerell 



Coelogyne is a remarkable genus of palaeotropical orchids, 

 with over a hundred species, distributed from India to the 

 New Hebrides. The type species, C. cristata Lindley, comes 

 from the base of the Himalayas, and has beautiful white fiowers, 

 the lip marked with orange. The most remarkable thing 

 about the genus is, perhaps, that the lip in some of the species is 

 marked with black. I have before me a number of fresh fiowers 

 of C. pandurata Lindley, from Borneo. The profuse marking 

 of the pale greenish lip is dull black, with a very faint rusty tint. 

 The small concavity at the extreme base is cinnamon-brown. 

 The other petals, and the long sepals, are pale yellowish green. 

 The column or gynostemium is suffused with apple green, espe- 

 cially at the tip. The bright orange pollinia rest on a broad 

 crenulate or subfimbriate base. The lip is described by Nash* 

 as 2-keeled, but Pfitzer and Kranzlint treat it as 3-keeled in their 

 key. There is actually a well-developed median keel, but it is 

 smaller than the others. CostantinJ gives a colored figure of 



C. pandurata, but unfortunately it is colored bright bluish-green, 

 whereas the color should be like that of Trias oblonga on the 

 same plate.
