Acacia scabra Benth.

Family

Fabaceae

Description

Branchlets hispid to hispidulous with a mixture of short and long, patent hairs, without short, rigid, spinose laterals. Stipules c. 1.5 mm long, spinose but brittle. Phyllodes single or sometimes in fascicles, narrowly oblong or oblong-elliptic, 10–20 mm long, 2–3 mm wide, excentrically mucronulate, straight to shallowly sigmoid, finely wrinkled when dry, sparsely to moderately hispidulous, midrib not prominent. Peduncles 13-20 mm long, moderately hispid to hispidulous; heads globular (? or obloid). Flowers 5-merous; sepals free. Immature pods not coiled, flat, glabrous.

Notes

Acacia scabra may be simply a variant of A. nodiflora with slightly larger phyllodes; however, further study is needed to properly assess its taxonomic status. It has some similarities to A. parkerae. Acacia scabra is known only from the type collection. The G, NSW and P isotypes are given as Drummond’s second collection, which if correct means the species was gathered between the Swan R. and Augusta, fide R.Erickson, The Drummonds of Hawthornden (1969). This area is more than 200 km S of the known geographic range of A. nodiflora and it is unlikely that the type of A. scabra came from this area. There are specimens of A. congesta at Herb. K and P which are also labelled Drummond 162.
