Hibiscus inimicus Craven, F.D.Wilson & Fryxell

Shrub 1–3 m high. Branchlets with stellate hairs (usually only coarse tubercle-based hairs are present, fine hairs are often absent, hairs sparse to moderately dense, fine hairs 0.2–0.4 mm long, coarse hairs 0.4–1.5 mm long), aculei (1–3.7 mm long) and glandular hairs. Stipules ± persistent, subulate or narrowly triangular, 6–14 mm long. Climax leaves: petiole 70–100 mm long, indumentum dissimilar to branchlet (stellate hairs of the petiole denser, aculei rarely present and with a longitudinal band of fine stellate hairs on adaxial surface); lamina broadly elliptic or broadly ovate or circular, moderately 3-lobed (the lobes longer than wide to as long as wide), 80–130 mm long, 80–150 mm wide, cordate base, serrate to serrulate margin, acute or obtuse or acuminate apex, usually strongly discolorous (the abaxial surface greyish and often brightly so), the indumentum denser on abaxial surface, with coarse stellate hairs on the veins and sometimes with scattered fine stellate hairs on the interveinal regions (stellate hairs moderately to very dense and fine or coarse, fine hairs 0.15–0.4 mm long, coarse hairs 0.5–1 mm long), very rarely aculeate (2–4 mm long), and glandular hairs. Distal leaves reduced in size, narrowly ovate or ovate. Foliar nectary at lamina base, 3–4 mm long, or absent. Flowers solitary in leaf axils or sympodial in few-to several-flowered terminal and/or distal-axillary racemoid axes; peduncle 11–60 mm long (on axillary flowers 40–60 mm long, on sympodia 11–25 mm long), with stellate hairs and aculei; pedicel 10–29 mm long, (on axillary flowers long 15–29 mm, 10–11 mm long on sympodia), indumentum dissimilar to the peduncle with stellate hairs and very dense aculei; epicalyx with stellate hairs and aculei, 10-segmented, segments free at the base, incurved, linear, obscurely 1-veined, 0.8–1 times the length of the calyx, 21–31 mm long; calyx at anthesis 26–31 mm long, indumentum whitish or yellowish, with very dense stellate hairs and aculei, calyx nectaries absent; petals 70–90 mm long, pink with the proximal region reddish; staminal column 23–30 mm long with the stamens distributed throughout its length, the filaments 1–2 mm long; style exserted 8–10 mm beyond the apex of the staminal column, the branches 3–5 mm long, stigmas capitate, stigma hairs 1 mm long. Capsule ovoid, c. 16 mm long, densely hairy, the hairs appressed, the beak c. 2 mm long. 

Recorded in sandstone woodlands and gullies, often associated with seasonal waterways.
