Altitude range: 0-1400 metres above sea level.
Habitat: Chihuahuan Desert, in xerophyllous scrub, grasslands, openings in oak woodlands, Tamaulipan thorn scrub, on deep soils, sandy soils of plains and valleys, saline flats, low limestone hills or limy gravel above Permian red dirt.

 

Description: Echinocactus texensis, best known in cultivation as Homalocephala texensis, is a stout barrel cactus, which is solitary when young, very rarely slowly clustering in age.
Stem: Pale grey-green (desert populations) to grass green (eastern populations) with numerous ribs , above-ground portion flat-topped, hemispheric in old age but usually deep-seated, flush with soil surface 30 cm in diameter, 20 cm high.
Spines: Small but strong pale tan, pink, reddish to grey, terete to flattened, annulated, not hiding stem surfaces.
Radial spines: (5-)6-7 per per areole, mostly decurved
Central spine: 1 porrect and straight.
Flowers: 5-6 × 5-6 cm. Flowers range from white thru rose-pink to pale silvery-pink, with red throats in late spring and can appear on plants around 10cm in diameter.
Fruits: Scarlet or crimson, spheric to ovoid, 15-50 × 15-40 mm, fleshy.
