Baja_Costero (Baja California - Zone 11b) on Sep 27, 2022 9:31 PM concerning plant:
Solitary or more commonly dichotomously branching bubble cactus with olive green or gray-green stems and short spines. Stems may reach up to 4 inches tall and 2-2.5 inches in diameter. In advanced age, branching plants may reach 12 inches or wider. 2-5 short, rigid central spines; 16-30 short, white radial spines; axils with sparse wool (more abundant in some clones and sometimes alternating over time). Flowers are rather small and purplish pink, and may not open very far. This species is from Oaxaca in southern Mexico, where it grows on gypsum cliffs.
Two subspecies: crucigera (almost always branching, 4-5 yellow or brown central spines, 22-30 radials); tlalocii (solitary, 2-4 whitish central spines, 16-22 radials, tending to grow taller). The former ssp. grandinosa (black spines) is apparently no longer a thing.
