measurements of the description and is cited after the 
description in the position of a cotype, must be consid- 
ered as truly representing this concept. It shows, how- 
ever, certain marked discrepancies from the description, 
and it appears that these characters should be noted. 
The longest leaf measures 9 cm. in length, whereas 
the description gives the maximum length as 10cm. The 
peduncle with the rachis of the raceme is about 16 cm. 
high, whereas the diagnosis gives a height of 25-83 cm. 
and it appears more or less angulate rather than terete. 
The most important discrepancy seems to exist in the 
veining of the petals and lip—a character which is very 
generally considered of major importance in separating 
the species of the genus Telipogon. The petals of this 
collection are 18-nerved (not 19-nerved), and the lip is 
only 17-nerved (not 29-nerved). Moreover, both the pet- 
als and lip bear numerous, though indistinct, oblique 
cross-reticulations which are not described.

This concept, which was described from a single flow- 
er, was said to differ from 7°. muralis by having the dor- 
sal sepal shorter than the lateral sepals, by having the 
base of the lip ecallose and by having the lateral lobes of 
the lip semiovate from a clawed base, rather than linear 
or oblong. 
Actually the shorter appearance of the dorsal sepal was 
in part caused, as Reichenbach says (l.c.), by its cucul- 
late character, so that there seems to be little difference 
in length when this organ is expanded. 
In the Ames Herbarium there are two collections, one 
from Ecuador and one from Peru, which have the short
