between the concepts appears to be that Aa Lechleri is 
described as having longer lateral sepals than A/tensteinia 
Matthewsi.

A comparison of Stenoptera acuta, as represented by 
a photograph of that species from the Lindley Herbarium 
at Kew, as well as by the detailed description and figure 
in Cogniaux’s treatment of S.acuta (l.c.), shows that it 
cannot reasonably be separated from S. e/ata as repre- 
sented by the description and figure (l.c.). 
In fact the only discrepancies between the two con- 
cepts seem to be that S.e/ata is described as a rather taller 
plant with somewhat larger leaves and longer spike than 
S. acuta. 
A Peruvian specimen referable to S. acuta ( Weber- 
bauer 7585) is almost as tall as 8. elata and has even 
longer leaves than that concept.
