This is a very rare plant. It appears to have been 
introduced in 1793, but was probably soon lost again. 
Within a few months it has been imported from the 
West Indies, and. exists for the present in two or three col- 
lections about London. Our drawing was made at Mr. 
Colvill’s. 
The plant is preserved, with great difficulty, by being 
planted in decayed wood and peaty soil. It is found in va- 
rious islands of the West Indies. 
The genus Isochilus is one of those published by Mr. 
Brown, in his celebrated arrangement of Orchidez, in the 
2d edition of the Hortus Kewensis: one species has been al- 
ready figured at p. 745 of this work, and we shall soon take 
an opportunity of giving a figure of a third species. It be- 
longs to a section of Epidendreze, which we characterize 
by having four pollen-masses, and a perianthium either
