To complete the survey of the Trinidad species that have been 

 referred to C. cristatum Lindl. it is now proposed to amplify the 

 brief characterization which Lindley published in the Botanical 

 Register for 1841. The remarks that follow are based on mate- 

 rial in my herbarium that consists of a few flowers and a very 

 clear tracing taken from Lind ley's specimen of Schomburgk's 

 628 preserved at Kew. For this material and for the opportunity 

 to clear away ambiguity I am indebted to Sir David Prain. 



The type specimen of Cyrtopodium cristatum was collected by 

 Schomburgk in what is now British Guiana and bears the num- 

 ber 628. Lindley in his list of Schomburgk's orchids, a list which 

 appeared in Bentham's series of contributions toward a Flora 

 of South America, gave the habitat of C. cristatum as rocks and 

 trees. 



In habit Lindley's type resembles C. Broadwayi very closely 

 and might easily be mistaken for it until flowers of the two spe- 

 cies are compared side by side ; but it is very surprising that it 

 should have been confused with Otostylis hrachystalioo, which has 

 white flowers and short scale-like bracts subtending the pedicels, 

 not to mention the very different lip with much reduced lateral 

 lobes. 



Sepals ±14 mm. long, and about 8 mm. wide, conspicuously 

 nine-nerved in dried specimens, elliptic-ovate, hardly acute, 

 rather fleshy in texture, spreading, with undulate margins. Petals
