Description

In Flora Australiensis, Bentham describes it as:

O. paucidentata, F. Muell. Fragm. v. 66. An undershrub or shrub of 2 to 3 ft., scabrous-pubescent or hispid with short septate hairs and often somewhat viscid. Leaves oblong-linear or oblanceolate and ½ to 1 in. long or shorter and obovate, obtuse, narrowed into a petiole, with 1 or 2 prominent teeth or lobes on each side or occasionally entire, the margins usually recurved. Flower-heads rather small, on peduncles usually longer than the leaves, forming a terminal leafy panicle. Involucre hemispherical, the bracts narrow, almost acute, the inner ones about 2 lines or in large heads 2½ lines long Ray florets 12 to 20 ; disk-florets more numerous, scarcely exceeding the involucre. Style-appendages short. Achenes pubescent. Pappus rather short, slightly unequal, with sometimes a very few short outer bristles - Eurybiaia paucidentata, Steetz in Pl. Preiss. i. 420 ; Aster paucidentatus, F. Muell Fragm. v. 66.

W. Australia. Swan River. Drummond, Ist Coll., also n. 31. 31. and 4th Coll. n. 128; Preiss n. 74, 84, and n.80 in part; Franklin and Blackwood rivers, Oldfield.
Var. latifolia, Drummond, 2nd Coll. n. 172; Plantagenet and Stirling ranges,Maxwell.

The species varies much in the breadth of the leaf, the more or less copious indumentum, and in the size of the flower-heads[2]
