Fig. 185.—Joint of Acanthoce-reus occidentalis. X0.5. 126 THE CACTACEAE. undulate; areoles 2 to 3 cm. apart, small, brown-felted; spines 2 to 6, acicular, brown, swollen atbase, unequal, the longest 2 cm. long; flowers and fruit unknown. Collected near Barrinha, Bahia, Brazil, by Rose and Russell, June 8, 1915 (No. 19808). This is a very distinct and remarkable plant. In the shape and color of the branchesit suggests some species of Hylocereus such as H. ocamponis, but it is a true terrestrial andnever develops aerial roots. It is inconspicuous, growing in the bushy flats, and easilyoverlooked. Numerous cuttings were sent to the New York Botanical Garden by Dr.Rose, but only one of these lived, and this has not yet made any new growth. It may notbe of this genus, for it does not resemble closely any of the described species. Figure 187 is from a photograph taken by Paul G. Russell in 1915 at the type locality.
