Hab. On trunks of trees near Lloa, " western declivity of 



Pichincha. Prof. W. Jameson. 



This is one of the many extremely beautiful epiphytes, with 

 which I have been favoured by Professor W. Jameson, from the 

 environs of Quito. It is amongst the largest of the genus; the 

 stem has, near the middle, a single long, sheathing scale,- and 

 the spikes arise from a spatha, not from the base of the leaf, as 

 is usual in the genus, but from the stem, at a little distance 

 below the leaf.
