Flowers solitary or in cymes of 2-4; pedicel 0.5-1.5 cm; epicalyx lobes closely adnate to calyx, scalelike. Sepals linear, up to 2.8 × 0.4 cm, both surfaces puberulent. Petals greenish white, oblanceolate, as long as sepals. Androgynophore ca. 2.5 mm; staminodes filiform, slightly longer than stamens. Ovary ovoid, villous; style glabrous.

The roots of Pterospermum heterophyllum are of medicinal use. The epithet refers to the great contrast in form between juvenile and mature leaves but this is not unique to this species.
