Cephalocereus brasiliensis sp nov

Somewhat branching at base, 1 to 3 meters high, producing long, slender, weak branches, these at first erect, but soon spreading or reclining, bright green when old, but when young somewhat glaucous; branches at base nearly square in section, but toward the tip with 4, sometimes 5, prominent obtuse ribs; areoles very close together, with long white hairs longer than the spines;

radial spines several, very short, brown, spreading, acicular; central spines generally solitary, porrect, 1 to 2 cm. long; flowers 5 cm. long; fruit globular.

Collected by Rose and Russell on the base of Corcovado, Rio de Janeiro, Brazil, July 10, 1915 (No. 20190).

This plant is not uncommonly found with Cephalocereus fluminensis, but is not as abundant as that species.

In the open flats and valleys toward Cabo Frio, Brazil, similar plants occur, but they are stouter and usually erect; of these, flowers and fruit were not obtained (Rose, No. 20705).

Figure 84 is from a photograph taken by Paul G. Russell of the type plant.
