Common name: Hairy Sida
Sida trichopoda F.Muell. APNI*
Description: Erect subshrub 40–90 cm tall; sparsely pubescent to densely stellate-hairy often with few leaves.
Leaves narrowly ovate-oblong to broad-obovate, mostly 1–3 cm long, 1–15 mm wide, occasionally a few scattered broader leaves present, rounded at base; margins serrate; both surfaces green and stellate-hairy or the lower surface glabrous; stipules 2–4.2 mm long.
Flowers axillary, solitary, pedicels exceeding leaves, mostly 10–60 mm long, subglabrous below articulation, densely pubescent above. Calyx unribbed, 4–5 mm long; lobes acute, 1.8–2.5 mm long. Petals 5–15 mm long, often deeply emarginate.
Fruit transversely elliptic, somewhat flattened, 5–7 mm diam., pubescent to glabrous, wrinkled at least about circumference, stellate-pubescent, usually with simple, curled, multicellular hairs on back, flat or with a raised, rounded or acuminate central portion; mericarps 6–9, reticulate on lateral wall, unawned.
Distribution and occurrence: Grows on heavy clay soils, often in gilgais, sometimes in red loamy soils.

Other Australian states: Qld Vic. S.A. N.T.
Usually recognized by its long pedicels, far exceeding the subtending leaves. The pedicel is articulate near the apex and is frequently glabrous below the articulation, contrasting with the dense pubescence above. This pubescence consists of stellate hairs mixed with simple, curled, multicellular hairs.
