Probably allied to C. aucheriana, N. E. Br., of which I have seen no 
flowering specimens, but according to the description of the flowers of 
that species given by Boissier, this plant clearly differs by its long 
pedicels and much larger corolla. 2

A very distinct and easily recognis pein. In the other i 
known to me the corona, or at least the base of the asi er column, is 
re or less included in a short tube or depression at the the 
corolla, butin C. Luntii the base ofthe corolla is flat, with the eorona 
raised well above it on the stout staminal column, which is of equal 
diameter with the corona.
