Perennial with usually many little-branched stems up to 30 cm long from a somewhat woody base, stiffly erect to decumbent or prostrate; stems quadrangular, rarely terete later, with long spreading hairs below and/ or with short recurred hairs above, rarely glabrous but always with some bristles or papillae on the node or the leaf sheath; leaves and stipules equal, in whorls of 4, linear to linear-lanceolate, 3-12 mm long, acute and if with a terminal bristle it is similar to the few spreading ones on the upper surface and especially along the usually strongly recurred margin, usually stiffly erect.

G. gaudichaudii is, next to G. migrans, the most common species in S.Aust. and varies from delicate little-branched annuals to densely tufted perennials with a somewhat woody tap root. It is distinguished by its almost sessile flowers and fruit being often clasped by the subtending linear leaves and its internodes which are usually 10-20 mm long at least on some parts of the plants.
