Simple or proliferous at base, globose to short-columnar, woolly at apex; ribs 20 or 21, crenate, pale green; radial spines about 20, somewhat acicular, 1 cm. long; central spines 6 to 8, 2 cm. long; flowers pink, 5 cm. broad when fully expanded; perianth-segments narrow, acute, the inner ones toothed toward the apex; filaments white, short; style white, with yellow stigma-lobes; the scales of the ovary and flower-tube bearing in their axils short wool and some of them a long white hair much longer than the scale.
Type locality: Chile.
Distribution: Western part of the Andes of Chile.
This species was originally described as having yellow flowers and naked scales but this was evidently an error.
E. chilensis confinis Hildmann (Schumann, Gesamtb. Kakteen 424. 1898) is said to differ from the species in its shorter yellow central spines.
