description_en: Genus of 4-6 species of slow-growing, perennial cacti occurring in dry, arid areas of the USA (S. Texas), and N. and C. Mexico. They have spherical or hemispherical, ribbed stems, some becoming columnar when mature, with woolly, occasionally spiny areoles. Solitary, large, funnel-shaped, diurnal yellow flowers, some with red-tinted throats, are produced in summer. They are followed by ovoid, green or red berries containing boat-shaped, black or brown seeds. Where temperatures fall below 10°C (50°F), grow in a temperate greenhouse. In warmer climates, grow in a desert garden.
