ONCIDIUM 



(E.) macrochihm. Raceme many-Dowered, very flexuose. Lip whole-coloured, 

 onc inch and a half Lroad. 



A niost variable plant. of whicli D. is, I now doubt not, ir.erely an alpine form, in 

 which tiie crest consisis of ihree rounded tubercles; in C, the lubercles are acute, 

 and there are iwo minute additional teelh on each side; in B. there are ihree tu- 

 bercles, the middle one of which is very small, and ihe laterals abruptly rostrate; in 

 A. ihere are ihree only, and acute; in all tliere is a tuft of hairs at the foot of ihe 

 column, on the crest. The leaves are equally changeable ; in A. they vary from ob- 

 long 10 narrowly lorate, and in C. they are spaihulate. In the colour and size of 

 the flowers difl^erences are equaily abundant. AII are very handsome, most especially 

 E,, which is by far ihe flnest Alpine Orchid yet discovered.

This also comes from La Guayra, whence Mr. Barker reccivcd it. Alihough ihe 

 flowers are small, they are vcry beautiful, having a deep crimson lip , richly studded 

 with clear purple spots. In ihe smallness of its anihers , ihe extension of the anihcr 

 bed Ibchind into an elevated lim , and in ihe shoriness of ihe column wings, it is 

 somewhat diirerent from ihe resi of the genus. I have only seen a couple of flowers.
