As a genus, Trichocentrum must rank next to ZEceoclades, 
from which it principally differs in having the labellum 
united at the base with the column, and in the latter having 
two ears or wings. It is also close upon Angrecum and 
Mystacidium, with which it agrees in habit, but from which 
it is abundantly distinct. 
To the two species now admitted into the genus Tricho- 
centrum, must, I think, be added, as a third, the Zimodorum 
funale of Swartz, a very curious leafless Jamaica epiphyte, 
which no modern botanist seems to have met with alive, and 
which I only know from Swartz's description. He states it 
to grow upon old trunks of trees on the mountains of Jamaica, 
emitting numerous, simple, stiff, thick, pale green roots, 
from two.to three feet long, and having, in the spring, large 
whitish flowers in pairs. This plant ought to be sought for 
again; if it were not found, there would be other species to 
reward the trouble of the traveller, for I see there are not 
fewer than twenty species of Jamaica epiphytes described by 
Swartz, of which none have as yet reached England alive ; 
not to mention the Cymbidium utriculatum, a terrestrial 
species inhabiting moist woods on the island, having a tuber 
as large as the largest potatoe, a scape about two feet high, 
Calanthe-like leaves, and pretty large (majusculi) white 
succulent flowers.
