Roots: fibrous.

Sap: without latex.

Tubercule arrangement:

Tubercule: Conical, blue green.

Axil: Densely woolly and with white bristles to 10 mm (0.4 in) long.

Radial spine: 16 - 20, straight, smooth, stiff, white, 5 - 10 mm (0.2 - 0.4 in) long.

Central spine: 3 - 4, straight, purplish brown with lighter base, to 15 mm (0.6 in) long, lower one hooked and longer.

Flower: There are distincly two colour forms recorded, the first, as originally described is white, with pinkish midstrips at the tips of the outer petals, often narrow and quite widely separated; the second form is much more deeply coloured, with deep pink petals and maroon midstripe, stigma-lobes on both forms are yellowish olive-green. Size to 20 mm (0.8 in) long and 30 mm (1.2 in) in diameter.

Habitat Substrate:

Geographic Distribution: Angel de la Guarda and Ventana Islands, and the region of Bahia de Los Angeles on the Baja California Peninsula, Mexico. Altitude near sea level to 300 m.

Comments: In culture, mineral substrate. Requires an open soil with excellent drainage. Clustering if the plant can be kept alive long enough. Like many Baja California species, difficult in cultivation, but a careful hand with watering will help.
