The description and floral analysis of Pterichts seleni- 
glossa show that this concept is specifically inseparable 
from Acraea triloba as represented by a photograph with 
floral analysis from the Lindley Herbarium at Kew. 
Acraea triloba appears to be a somewhat taller plant 
with a larger leaf than the type of Pterichis seleniglossa 
and has insignificant floral differences. However, a series 
of Peruvian collections which have come under our obser- 
vation indicates that we are here concerned with a single 
variable species.
