A new species of the curious genus Peristeria, imported 

 from the Spanish Main by Mr. Knight of the King's Road, 

 in whose Nursery the accompanying figure was made in 

 June last. 



It is allied to the P. pendula of the Botanical Magazine, 

 from which it differs in its spotless, smaller flowers, in the 

 crisped border of the middle lobe of the labellum, and espe- 

 cially in the absence of wings from the column. This latter 



* From TTtpioTtpa a dove : the column in the original species, P. elala, 

 resembles a dove hovering with expanded wings.
