Common name: Hill sida.

Description:
Shrubs often c. 1 m high but up to 2.5 m, densely stellate-tomentose with golden or ferruginous hairs on the younger parts; leaf blades usually one and a half to two times as long as the petioles, oblong to ovate-lanceolate, 10-75 x 2-24 mm, obtuse or cordate at the base, bluntly or acutely dentate with 6-12 teeth/cm to subentire, densely velvety-tomentose.

Flowers solitary in the axils of leaves or in axillary clusters of 2-6 through an association with developing shoots, on articulated peduncles 4-20 mm long; calyx 5-10 mm long, not greatly enlarging in fruit, densely tomentose, with lobes divided to about the middle, acute or acuminate, clasping the fruit; corolla 7-12 mm long, yellow.

Schizocarp transverse-ellipsoid, raised apically, pubescent, 4-6 mm diam., slightly wrinkled on the circumference, the 5 rarely 6 mericarps honey-combed on their sides.

Taxonomic notes: As proposed by Mitchell in Jessop (1981) Flora of central Australia S. cryphiopetala and S. phaeotricha are treated as likely to be synonymous and the earlier name is therefore adopted here. Specimens from the Everard Range (NW) with a lighter coloured finer tomentum and only 1-3 mericarps developing in fruit may represent a distinct taxon.
