Otinapa, July-August, 1906, H. Palmer, no. 361 (type, in hb. Gray). 
The peculiar pruinose appearance of the inflorescence is due to the 
white puberulence closely covering the purplish bracts and flowers.

1906, H. Palmer, no. 376 (type, in hb. Gray). This species is rela 
to C. macrostigma, differing in pubescence, densely flowered spike, and 
large bracts ; from C. angustata it differs in pubescence, stigma, foliages 
and flowers. There are resemblances to C. glandulosa chiefly in the form 
of the spike, but the bracts in C. Palmeri are rounded at apex rat 
than rhomboid. The corolla is quite dissimilar, the lower lip with three 
long almost equal divisions, and the body extending outward like a shelf, 
being very different from the trisaccate lower lip of C. glandulosa with 
its short divisions separated by the folds forming the sacs. ;
