Threat status:Victoria: rare (r)

Prostrate to decumbent shrublets with branches to c. 30 cm long. Vestiture of stems of tubercle-based, mainly simple hairs over short simple and/or stellate hairs. Leaves linear, (2–)2.5–6.5(–10) mm long, (0.8–)1–1.3 mm wide, sparsely covered with short, sometimes tubercle-based hairs; petiole 0.2–0.6 mm long; apex obtuse or acute, usually with terminal tuft of hairs on projecting central ridge; margins revolute, usually raised above adjoining central ridge, obscuring the lower lamina. Flowers sessile or on peduncles to 6 mm long, terminal, with 1–3 linear-lanceolate bracts 1–2.4 mm long; sepals 5–6 mm long, unequal, pubescent, rarely glabrous; petals oblanceolate to obovate, 5–7.7 mm long, yellow; stamens (2–)4–6(–9), in one cluster, sometimes with 1 or 2 stamens on other side of the ovary; filaments free but often dilated basally; carpels 2(3), tomentose or pubescent. Flowers mostly Sep.–Nov.

Also NSW. Uncommon and localised on rocky slopes and along creeks in riparian scrub in Gippsland (e.g. Snowy, Genoa, and Avon River gorges).

Vegetatively Hibbertia dispar closely resembles other taxa previously assigned to H. pedunculata (i.e. H. ericifolia, H. exponens, H. exposita, H. porcata, and H. samaria), but is readily distinguished by the reduced number (usually 4–6) of zygomorphically arranged stamens.
