 subcomplicato-acute carinatis, scapo paniculato multi-

A very beautiful and entirely new species, with foliage 

 resembling that of Oncidium triquetrum (Tab. 3393), and 

 Oncidium pulchellum (Tab. 2773), but very different in the 

 flowers, both as to form and colouring, being elegantly 

 varied with white and yellow, and blotched with blood- 

 coloured spots. It was sent to the Royal Gardens of Kew, 

 in the autumn of 1843, by our Collector, Mr. Purdie, from 

 Jamaica, and blossomed freely attached to a piece of wood 

 in March and April of the following year. 



Descr. Epiphyte. Stemless. Leaves subdistichous,
