Notes

Shrub to 3.5 m high. Stems cylindrical, glandular warty, densely hairy with stellate hairs (needs a hand lens or a macro app on your phone/tablet to see), eventually becoming hairless. Leaves aromatic when rubbed, opposite each other, compound, with 3 leaflets, each 1.6–5 cm long, 1.4–5 mm wide, tips rounded, margins more or less toothed; upper surface sparsely to moderately stellate-hairy, densely warty, and dull green; lower surface warty, stellate-tomentose, and whitish. Flowers creamy-white, with 4 petals each about 2.5–4 mm long, and with 4 stamens. Flower clusters shorter than the leaves, initially compact but then expanding, usually about 60–200-flowered. Bracts surrounding the flower bud clusters 6–13 mm long, often falling early. Flowers Winter to Spring.
