Notes
Shrub to 2 m high. Stems velvety, with mostly stellate hairs (needs a hand lens or a macro app on your phone/tablet to see), and a few simple and 2-armed hairs. Leaves aromatic when rubbed, opposite each other, compound. Leaves of two types, usually leaves with 1 leaflet and leaves with 3 leaflets on the same stems, more rarely all the leaves on a branch with 1 leaflet. Leaflets 2–6.5 cm long, 5.2–15 mm wide, tips blunt, margins entire, more or less flat, surfaces hairy, upper surface dark green, lower surface grey-green. Flowers white, tinged pink, with 4 petals each 3.5–5.2 mm long, and with 4 stamens. Flower clusters usually shorter than the leaves, occasionally much longer, 3–21-flowered. Bracts surrounding the flower bud clusters 5.2–12 mm long, remaining after the flowers open, densely white-hairy. Flowering: usually spring.
