Pomaderris is a genus of hairy shrubs and small trees found in Australia and New Zealand.

Characters (from Harden 1990): Shrubs or occasionally small trees; young stems, lower surface of leaves and inflorescences more or less tomentose, hairs generally stellate or mixed with, or concealed by, longer simple hairs. Leaves simple, alternate, petiolate; stipules brown, scarious, usually shed early. Flowers usually yellow or sometimes whitish, mostly c. 2 mm long, clustered in small cymes mostly grouped into terminal panicles or corymbs, sometimes in head-like clusters; bracts surrounding buds usually shed early. Hypanthium fused to ovary and disc. Sepals 5, often reflexed. Petals absent or 5 and often falling early, not enclosing the stamens. Stamens 5; filaments usually long and incurved. Disc annular, surrounding the base of the ovary. Ovary more or less half-inferior. Capsule septicidal, generally fused for about half its length to hypanthium; separating into 3 mericarps that open on inner face. Mostly flowering in spring, with buds apparent for many months before flowers open.
