Grusonia
Morphological Summary
Genus of cylindrical cacti in the family Cactaceae (subfamily Cylindropuntioideae) native to northern Mexico (especially Baja California and Sonora) and the southwestern United States. Grusonias are columnar or shrubby cacti with articulated cylindrical segments, similar to chollas (Cylindropuntia) with which they were historically confused or synonymised. They produce yellowish-green flowers and fleshy fruits. Adapted to the extreme conditions of the Sonoran Desert and Baja California deserts.
