Collected by Rose and Russell onthe base of Corcovado, Rio de Janeiro,Brazil, July io, 1915 (No. 20190). This plant is not uncommonlyfound with Cephalocereus fluminensis,but is not as abundant as that species. In the open flats and valleystoward Cabo Frio, Brazil, similarplants occur, but they are stouter andusually erect; of these, flowers and fruitwere not obtained (Rose, No. 20705). Figure 84 is from a photographtaken by Paul G. Russell of the Fig. 84.—Cephalocereus brasiliensis growing aboveCephalocereus fluminensis.
