Alepidea natalensis is an herbaceous perennial, 200–600 mm tall, with small leathery leaves and thin flower stalks, with small, white, star-shaped flowers at the tips. The stems are bare in the upper parts. The leaves are in a basal rosette narrowing to a stalk 10–20 mm long. They are dark green and leathery; the margins are entire or toothed and have bristles.

The star-shaped flowers are flowerheads, made up of many small flowers surrounded by petal-like bracts. The flowerheads are ± 15 mm in diameter, with 5 equal, triangular bracts, 5–6 mm long, and small alternating teeth. The floral bracts are white, but the margins become pink as they age. Flowering is in late summer to autumn (December to April).
