It has 5 or 6 radial spines 2 cm long and 0.8 cm wide, grey, the central spine may be absent or rudimentary; fertile zone not differentiated from the infertile zone. Plants bloom between August and January. Its flowers are white reach a length of 5 cm oblanceolate, mucronate apex, green, some with a red to purple middle stripe.
