genus Microcoelia contains some twenty-five or so spe- 
cies, but it is possible that some of these may prove to 
be conspecific. It is also practically certain that many 
new species yet await discovery, since the leafless habit 
renders the plants inconspicuous except when in flower, 
quite apart from the fact that some of the species are 
extremely small. 
‘The type specimens of the new species are in the Kew 
Herbarium unless otherwise stated.
