Plants simple, globular, often very large, sometimes 3 dm. in diameter, dull green; ribs 13 to 32 according to the size of the plant, low, very broad, sometimes 4 cm. long, separated by wavy inter- vals, divided into large, low, rounded tubercles; areoles 2 to 4 cm. apart, large, felted when young; spines dark brown to black, at first ascending, afterwards more or less curved outward, 8 to 10 on small plants but on old plants often 15 or more, 3 to 4 cm. long; central spines 1 to several; flowers white or slightly tinged with pink, cm. long, the tube short and broadly funnelform; inner perianth-segments spatulate, acute; scales of the ovary nearly orbicular, rounded, with a scarious Fig. 165.—Gymnocalycium saglione. Fig. 166.—Gymnocalycium gibbosum. Type locality: Catamarca, Tucuman, Argentina. Distribution: Northern Argentina and perhaps southern Bolivia. Our Bolivian reference is based on a living specimen and flowers collected by P. L. Porte at Lagunillas, southeastern Bolivia, July 1920, and delivered to us in good condition March 10, 1921; this may or may not belong here; it flowered May 7 and again on June 21, 1921. It may be described as follows: Ribs 8, obtuse; flower 3 to cm. long; flower-tube proper very short, only 1 to 2 mm. long; throat of flower broad, funnelform, 15 mm. long, bearing many stamens; inner surface of throat and tube deep reddish purple; filaments short, purple; style and stigma-lobes purple;
