190. 
An unusually widespread species in tropical and sub- 
tropical America, Habenaria repens, which normally 
grows in shallow water, was not cited from Trinidad by 
Cogniaux. Known from the island by but two collec- 
tions, it would appear not to be common.

This extraordinary little species of Jonopsis, known 
only from the type collection and apparently endemic to 
Trinidad, has never been figured. It has seemed advisa- 
ble to publish the accompanying drawing made from the 
duplicate type in the Orchid Herbarium of Oakes Ames.

Cogniaux has maintained Jonopsis pallidiflora as a dis- 
tinct species, principally on the basis of the bilobed gib- 
bosity at the connate base of the lateral sepals, separating 
it from I. utricularioides, in which the gibbosity is usually 
simple. All other characters are so similar that it does 
not seem that the structure of the gibbosity (which, in 
the somewhat variable Jonopsis utricularioides, is not con- 
stantly simple) alone suffices for maintainance of J. pal-
