Baja_Costero (Baja California - Zone 11b) on Sep 13, 2019 3:08 PM concerning plant:
Small, globose, spiny cacti from the southwestern US and northern Mexico. 7 species appear in Mexico, including 5 also found in west Texas. Plants in this genus usually have a hooked central spine, but sometimes have none at all. They flower in the spring. This genus has been separate from the ~8 species of Echinomastus in the past, but at the moment includes them. Their status is apparently controversial.
