Description
Pomaderris coomingalensis is a shrub that grows from 3 to 5 m tall. The young stems have a dense, greyish covering of stellate (star-shaped) hairs. The leaves are ovate or elliptic, 20 to 60 mm long by 7 to 18 mm wide; the base is cuneate (wedge shaped), the margins are entire, the apex is obtuse; the upper side of the lamina is glabrous, smooth with the lateral veins not or slightly impressed; the lower side of the lamina is pubescent with dense, greyish stellate hairs. The petiole is 2 to 5 mm long, stipules narrow-triangular or triangular, acute, 2 to 3 mm long. The inflorescence is 1 to 1.8 cm long by 1 to 1.5 cm wide and consists of 20 to 50 flowers. The flowers are cream or yellow; externally densely pubescent, consisting of sparse to moderate greyish or rusty simple hairs and dense, greyish stellate hairs; sepals 1.2 to 1.5 mm long, petals absent. The fruit has not been seen.
Pomaderris coomingalensis appears most closely related to P. clivicola which is also a Queensland endemic. Both species have relatively narrow leaves, very small apetalous flowers and similar indumentum, but P. coomingalensis is immediately distinguished by the leaves being glabrous (rather than minutely but densely stellate-pubescent) on the upper surface, and lacking simple hairs on the internerves of the lower surface (Walsh, 1997).
