一般的な情報:
This is the smallest species in the genus, and has the narrowest leaflets. It ressembles C. pityrophyllum, and some specimens that had been determined as C. parvum are now placed under C. pityrophyllum. However, C. parvum has slender filaments (of the staminodes), and staminodes that vary in number from 7-11, whereas C. pityrophyllum has broad-based filaments of the staminodes, and stamens and staminodes are always six in number. Apparently, C. parvum is a species that does not form large stands, while C. pityrophyllum does. It grows far from C. pityrophyllum, and only on the Western slopes of the Ecuadorian Andes.
