Flowers sessile, terminal mainly on short shoots with usually 1 triangular sheathing bract 1.3–2.6 mm long; sepals 3.8–5.4 mm long, unequal, glabrous; petals obovate, 5.2–10.4 mm long, bright yellow; stamens 20–25 in groups around the ovary; filaments free; carpels 2 or 3, glabrous.

EGU, HNF, HSF. Also Qld, NSW. Scattered and uncommon, usually on shallow, rocky soils in dryish open-forest and woodland, eastward from near Maffra (e.g. upper Avon River, Genoa River, Howe Range).

The leaves vary greatly in overall shape, as well as the number and shape of teeth within and between the widely separated populations throughout its range.

Hibbertia monogyna DC. is one of a number of forms of the H. diffusa complex which are in need of clearer delineation.
