Subshrub or shrub to 3 m high. Branchlets with stellate hairs of one size class (short soft stellate hairs 0.8–1.2 mm long, moderately dense to very dense and indumentum obscuring the epidermis), lacking glandular hairs. Climax leaves: petiole 20–60 mm long; lamina broadly elliptic, 3-lobed, 48–75 mm long, 45–73 mm wide, base cordate, margin serrate-dentate to crenate, apex acute to rounded, indumentum of short soft stellate hairs, yellowish. Flowers with the peduncle 7–48 mm long, pedicel present. Epicalyx shorter than the calyx, short soft stellate-hairy, 12–19-segmented, segments shortly connate at base, narrowly spathulate to spathulate, 10–21 mm long, 1–3 mm mm wide. Calyx short soft stellate-hairy on abaxial surface, campanulate, 20–28 mm long, lobes ovate, apex acute, 3-veined. Petals yellow with red basal spots, short coarse stellate-hairy on the abaxial surface, glabrous on the adaxial surface, 45–74 mm long, 35–38 mm wide, rounded at the apex. Staminal column glabrous, 15–26 mm long, antheriferous throughout, filaments 0.5–1 mm long. Ovary hairy, style arms 3–5 mm long. Capsule hairy, 18–25 mm long, 14–19 mm wide, beak 1–2 mm long. Seeds angular reniform, 3–3.5 mm long, concentrically ribbed, glabrous or short brownish to yellowish stellate-hairy.
Occurs in tall grassland with scattered trees of Eucalyptus koolpinensis in low lying area on red clay; on alluvial soil with Sorghum spp. near a floodway; on a lightly timbered plain on heavy grey stony pedocalcis soil; in partially cleared savannah on low ground; in an alluvial depression fringed with Eucalyptus oligantha and dominated by Sorghum australiense, Chrysopogon latifolius, other grasses and herbs; and on a sandy channel bank. The available specimen label data indicates that H. multilobatus occurs in low-lying situations that probably are seasonally inundated.
