Grevillea humilis Makinson APNI*
Description: Erect to spreading shrub 0.3–1.3 m high, rhizomatous; branchlets tomentose, subsericeous or almost glabrous.
Leaves spreading to ascending, sometimes irregular clusters of 3, narrow-elliptic to sublinear, usually 2–5 cm long and 1.5–2 mm wide, or in subsp. maritima to oblanceolate or narrowly obovate and to 6 mm wide, margins shortly once-refracted to scarcely recurved, upper surface sometimes punctate with midvein smooth or faintly granular, intramarginal veins prominent; lower surface mostly exposed, densely to sparsely subsericeous.
Conflorescences secund, 10–24-flowered, rachis straight or decurved. Perianth subsericeous outside, sometimes with weakly tomentose limb, profusely or sparingly bearded inside. Gynoecium usually 7–12 mm long; style hooked in apical 2 mm, glabrous except for minute hairs or papillae in the subapical 0.5 mm; pollen presenter oblique.
Distribution and occurrence: Grows north from Lake Macquarie.
