The leaves narrowly oblong to elliptic to oblanceolate, usually more hairy on the lower surface, margins smooth, apex pointed, and gradually narrowing toward the base with a noticeable tuft of soft hairs.

The white flowers are arranged in spike-like clusters up to 20 cm (7.9 in) long in leaf axils, corolla, 5–6 mm (0.20–0.24 in) long with more or less simple, soft, flattened hairs on the outside and short, soft hairs on the inside.

Flowering occurs from June to February and the fruit is cylinder-shaped, 3 mm (0.12 in) long, wrinkled, covered in short, soft hairs, ribbed and mostly one-seeded.
