medio sanguineo-lineatd, limbo obscure croceo maculato. Alee columna 



sanguineo fasciatce. 



This vei'y pretty species of Oncidium was imported 

 from Demerara by Messrs. Loddiges, with whom it flowered 

 in their stove for epiphytes in June last. 



It is in some measure related to O. Harrisonianum, from 

 which it is however abundantly distinct. The crescent- 

 shaped lip is, as far as I know, quite peculiar to this species ; 

 and the very blunt flat sepals conspicuously point it out. 



Fig. 1. is a magnified representation of the lip, with the 

 crest fringed with glands at the angles. Fig. 2. is the upper 

 end of the column, with the wedge-shaped banded appen- 

 dages, and the toothed clinandrium.
