which could be considered as specific; and since the con- 
cepts described by Cogniaux as N. apiculata and N. 
Broadwayi differ so slightly from NM. punctata that one 
would hardly be justified in calling them varieties. Mo- 
tylia incurva remains somewhat of a mystery. There is 
in the Trinidad Herbarium (2092) an inflorescence, the 
flowers of which differ from those of all other local ma- 
terial, which I am tentatively calling Notylia incurva. 
Lindley’s description of the concept is so vague that it 
would be difficult to assign this name with certainty to 
any specimen. The specimen 2092 was determined, pre- 
sumably at Kew by Rolfe, as representing this concept, 
and all of the characters of the flower would seem to 
agree with those specified by Lindley for Notylia incurva. 
Even though the name Notylia incurva is apparently 
rather ambiguous, I believe that the best course at pres- 
ent is to refer our specimen to it. The only certainty is 
that this specimen differs markedly, especially in shape 
of the lip, from all other Trinidad material. The lip is 
very broadly hastate instead of being very narrowly trul- 
liform. 
It would seem, then, that three species of Notylia are 
known from Trinidad and Tobago. These can be distin- 
guished according to the following key. 
1. Leaves narrowly linear. N. angustifolia 
1A. Leaves broadly oblong or elliptic. 
2. Lip narrowly trulliform, apically acute or subobtuse. 
N. punctata 
2A. Lip broadly hastate, subtrilobulate, apically rounded. 
N. incurva 
A summary of specimens referred to these concepts 
and a synonymy are herewith given.
