Pomaderris sp. C sensu Harden (1990) APNI*
Description: Shrub or small tree 2–5 m high. Young stems densely covered with pale stellate hairs. Stipules very narrowly triangular or linear, 3–5 mm long, caducous.
Leaves ovate to elliptic, 20–55 mm long, 15–30 mm wide; rather thin-textured; margins irregularly serrate or crenate, or rarely, quite entire, flat or margins very weakly recurved; adaxial lamina evenly covered with stellate hairs but the lamina remaining visible beneath the indumentum; abaxial lamina lightly covered with pale stellate hairs, the lamina quite apparent beneath; petiole 4–9 mm long.
Inflorescences of slender, terminal and upper-axillary panicles mostly 5–8 cm long, composed of numerous umbellate cymes, each of c. 4–10 flowers. bracts ovate to narrowly triangular, 1–2 mm long, deciduous; pedicels 1.5–3 mm long. Flowers cream to pale yellowish-green; externally densely covered with fine grey stellate hairs; sepals 1.2–1.5 mm long, deciduous; petals absent.

Flowering: Flowers November.
Distribution and occurrence: Known from a few localities in south-eastern New South Wales, in an area approximately bounded by the settlements of Bemboka, Brogo and Towamba. Commonly occurs in rocky sites, usually in the vicinity of watercourses, but also collected from moist forest on mid-slopes of low ridgelines.
NSW subdivisions: SC, ST
Most collections of P. viridis indicate association with P. aspera and P. cinerea, and it is believed to be likely that it is either an F1 hybrid with these two species as parents, or it is a true-breeding species of hybrid ancestry.
