Flora of New Zealand Series

Prostrate to ascending, perennial herb, becoming distinctly woody toward base. Lvs glabrous or sparsely hairy, especially when young, apetiolate and cuneate, usually elliptic-oblong, sometimes oblanceolate, deeply pinnatifid to 1-pinnate, (12)-15-30 × 5-12 mm; segments narrow-oblong, usually few-toothed, sometimes entire, (3)-5-(6) on each side. Uppermost lvs smaller, usually less divided. Supplementary bracts 3-5-(7), 2-3 mm long. Involucral bracts 11-13, glabrous or sparsely hairy, 4-5 mm long. Ray florets 0. Disc pale yellow, 5-9 mm diam. Achenes with scattered hairs in narrow grooves between broad ribs, slightly narrowed to apex, 2.8-3.4 mm long.

S.: Marlborough (White Bluffs, Marfells Beach and Cape Campbell).

Endemic.

Coastal mudstone gullies and cliffs.

FL Nov-Mar.

This sp., apparently a local endemic, was first collected in 1964. It is similar to prostrate forms of S. glaucophyllus with divided lvs, which occur in the same area, but is distinguished by the discoid heads and a chromosome number of 2 n = 60. Its closest relationships are probably with S. banksii (also 2 n = 60) of E. coast North Is. Plants of S. banksii from the southern part of the sp. range approach S. hauwai in lf shape but differ in being radiate, having less dissected lvs, more supplementary bracts and in being lanate.
