Bushy, i to 2 meters high; joints obovate to oblong, to cm. long, dull dark green; areoles distant, medium sized; spines 2 to 10, slightly spreading, very unequal, the longest ones cm. long, more or less twisted, flattened, dark brown; glochids few, soon disappearing; flowers 6cm. long, yellowish to orange, turning in age to dull red; ovary tuberculate, spineless, deeply umbilicate; fruit dark purple, turgid, juicy, deeply umbilicate, 5 cm. long. Type locality: Not cited. Distribution: Northern South America; sometimes assigned to Argentina. Opuntia schumannii is described by Berger as being intermediate between Opuntia and Nopalea, and according to him, it has long stamens and upright petals; otherwise it has little in common with Nopalea: a plant from Santa Clara, Colombia, which agrees with plants of 0. schumannii from La Mortola, Italy, has a normal Opuntia flower. Illustration: Card. Chron. III. 35: f. 16. Plate xxvu, figure i, represents a fruiting joint of the plant collected by John G. Sin- clair at Santa Clara, Colombia, in 1913; figure 2 shows a flower of the same plant. 161. Opuntia fuliginosa Griffiths, Rep. Mo. Bot. Card. 19: 262. 1908.
