Posted by Baja_Costero (Baja California - Zone 11b) on Aug 19, 2019 7:55 PM concerning plant:

Small, flattened globose, spineless cactus from south Texas, Nuevo León, and Tamaulipas. Looks a little like a sea urchin shell, thus the common name. Solitary, up to about 4 inches wide. Large yellow or yellowish white flowers; globose, scaly, hairy fruit. Ribs are low and separated by sharp furrows. Areoles are marked by low tufts of hair. Endangered in the US, vulnerable in Mexico.

A great variety of cultivars with unusual markings have been selected in cultivation, most with Japanese names. Among the most striking of these is Silver Dollar Cactus (Astrophytum asterias 'Super Kabuto') .
