Threat status:Victoria: endangered (e)
Decumbent to prostrate shrubs; branches to 50 cm long, pubescent to hirsute. Vestiture of long, simple, tubercle-based hairs over shorter simple hairs, rarely with the occasional forked hair. Leaves linear-lanceolate to linear, (1.3–)4–6(–7.4) mm long, 0.5–0.8 mm wide, sparsely hirsute to glabrous, ± glabrous on lower surface; petiole 0.3–1.2 mm long; apex obtuse or acute with a short tuft of hairs on the shortly projecting central ridge; margins revolute, flush with or raised above adjacent central ridge. Flowers on peduncles 4–10(–16.8) mm long, terminal, with 1(–2) linear to linear-lanceolate bracts (1.3–)4–6(–7.8) mm long, bracts distant from flower; sepals (4.6–)5.5–7(–7.8) mm long, unequal, hirsute to strigose, prominently ridged; petals broadly obovate, c. 11 mm long, yellow; stamens 15–25, rarely with a few staminodes, filaments free but often dilated basally; carpels 3, hirsute. Flowers Oct.–Nov.
HSF. Also NSW. Known in Victoria from a single record near Christmas Hills, north east of Melbourne in dry sclerophyll forest.
Hibbertia porcata may be distinguished from other taxa previously assigned to H. pedunculata (i.e. H. dispar, H. exponens, H. exposita, and H. samaria) by the prominent central ridge of the calyx which is accentuated by its recurved margins, and the long, simple, tubercle-based hairs on the upper surface of leaves and the calyx. Hairs on the upper surface of leaves are seldom forked, a feature of H. samaria, and leaves are glabrous on the lower surface.
