Southwestern cordillera of the Ecuadorian Andes, at 1500 m elevation, in premontane forests. It is only known as isolated individuals, not forming large populations, and usually kept standing on pastures. (Maria Jose Sanin & Gloria Geleano in Phytotaxa 34 (2011))B


  • This species resembles C. pityrophyllum, and some specimens that had been determined as C. parvum are here 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.

  • Subcanopy palm. Stem solitary, to 10 m tall, 10-20 cm in diameter, greenish grey to grey. Leaves 1.5-2.5 meters long; pinnae 90-120 on each side, inserted in groups of 2-6 or sometimes more and spreading in different planes, but leaf not strongly bushy; central pinnae 50-80 cm long and 2-3 cm wide, below with a thin, silverish layer of wax.
