9 



hooded over it. Column very short, without a foot ; anther 

 terminal, opercular, incumbent, rather flat, indistinctly 2-celled ; 

 pollinia 2, globose, waxy, with short filiform stalks. Capsule 

 small, shortly ellipsoidal, dehiscing from the apex by six valves 

 which are alternately broad and narrow. 



Species, only one known, native of Jamaica and Cuba. 



The genus is very near to Campylocentrum, in which it has been 

 included, but differs in the inflorescence, the lip, the form of the anther, 

 and the form and dehiscence of the capsule. 



It is dedicated to Mr. Wiliam Harris, F.L.S., Superintendent of 

 Public Gardens, Jamaica, and an indefatigable collector, who has added 

 much to our knowledge of the Jamaican Flora.
