This Bolivian cactus has usually solitary, compact depressed-globose stems armed with neatly arranged black spines. The centrals are typically stout and hooked, in juvenile plants, but tend to be straighter in more mature individuals. Another charming feature of the population offered here is its range of flower color: yellow or orange as well as the dark red typical of the species, which is native to Dept. Chuquisaca of southern Bolivia. HBG 108052, plants grown from seed. $6.
