The description of Prescottia gracilis together with [ 
a habit drawing and floral analysis made under the direc- | 
tion of Rudolf Schlechter shows that it is inseparable i 
from P. oligantha. 
Prescottia panamensis appears also to be synonymous r 
with P. oligantha, the type of the former differing only I 
in being a vegetatively smaller form and having a more I 
densely pubescent disc of the lip. 
As at present understood, Prescottia oligantha ex- I 
tends from southern Florida and Mexico to Panama and * 
Colombia, from the Bahamas through the West Indies j 
to Granada and a recent collection from Mt. Auyan- ; 
Tepui (G.H.H. Tate 1239) extends the range to Ven- | 
ezuela. 
Other species which appear to be very closely related I 
to P. oligantha are the Brazilian P.densiflora (Brongn.) 
Lindl., the Colombian P.filiformis Schltr. and the Brazil¬ 
ian P.viacola Rodr. all of which differ from it chiefly 1° | 
having an acute or acuminate lip.
