Publication originale:
"163. Opuntia distans sp. nov.
Erect, densely much branched, 3 to 4 meters tall, with a short trunk 1.5 dm. in diameter; joints flat, bluish green when young, grayish green when old, obovate, 2 to 2.5 dm. long, about 1.5 dm. wide and nearly 2 cm. thick, rounded above, narrowed at the base, glabrous; areoles few, only about 12 on each side of a joint, distant, large, nearly circular, 8 to 10 mm. broad, slightly elevated, bearing many short glochids, but quite spineless; leaves subulate, about 3 mm long; ovary obconic, 3 to 4 cm. long, bearing a few small areoles; sepals broadly triangular, acute, 6 to 10 mm. long; petals broad, rounded, 1 to 2 cm. long, orange-red.
Distribution: Sandy places, Andalgala, Catamarca, Argentina, J. A. Shafer, December 15, 1916 (No. 7).
A spineless species noteworthy for its few, large, distant areoles. We append it to the series Elatiores, but are uncertain as to its real affinity. The large distant areoles forbid associating it with the Ficus-indicae or the Streptacanthae.
Figure 195 represents a joint of the type specimen".
Type: J. A. Shafer 7, Argentine, Catamarca, Andalgala, 15 decembre 1916, conservé au New York Botanical Garden (NY: holotype), à Kew et à l'herbier national américain du Smithsonian Institution à Washington (K et US 764797: isotypes).
