Taxon concept:

 Key to the subspecies 
1Leaves with ultimate lobes cuneate or ovate, rarely linear; most of lower surface of lobes exposed, margins recurved; inflorescences usually >5 cm long. Shrub to 2 m highsubsp. acanthifolia
Leaves with ultimate lobes linear or subulate; most of lower surface enclosed by the refracted margin; inflorescences usually ≤ 5 cm long2
2Pollen presenter oblique, broad-conical; lower surface of leaves glabrous except for scattered appressed hairs on the veins; branchlets glabrous or pubescent; stipe ≥ 1.5 mm long; low spreading shrub usually <1 m highsubsp. stenomera
Pollen presenter an erect cone; lower surface of some or all leaves with white appressed hairs on the lamina on either side of the veins; branchlets subsericeous with ridges sometimes glabrous; stipe ≤ 1.5 mm long; erect spreading shrub up to 3 m high
