Trichocentrum is a small genus of Vandea, allied to Bur- 

 lingtonia and, like it, a native of South America, where the 

 species are distributed from Peru and Brazil to Mexico ; but 

 few are known, and amongst those in cultivation the present 

 is by far the prettiest ; the only other figured in an English 

 work is the sombre-coloured T.fuscum (Tab. nostr. 3969), 

 from Mexico. t . 



T. albo-purpureum was introduced by M. Linden, it is be- 

 lieved, from the Eio Negro, in North Brazil, according to 

 Reichenbach in the 'Gardeners' Chronicle,' who gives au 

 excellent woodcut representation of the flower, and who 

 further states that two varieties of it are known, one with a 

 narrow and the other with a very broad lip. The specimen 

 here figured flowered with Mr. W. Saunders,_ F.RS., at Rei- 

 gate; its sepals are more obtuse, and the lip a little nar- 

 rower than in the figure of the ' Gardeners' Chronicle.
