Diagnosis: — Differs from the type variety by the following traits: indumentum of the leaf upper surface comprising long straight simple hairs and a dense, persistent, cover of much shorter, stellate hairs with 4–12 spreading branches ca. 100 μm long, arising from a bulbous base.

Shrub with flattish spreading crown. Leaf blade large, with at least a few exceeding 18 × 10 cm, lower surface always with a very thick fulvous tomentum of woolly hairs, completely hiding the areoles and reticulum. Fruit: wings often larger than in the type, 2.0–5.0 cm long, attenuate at base.
