Perennials with many usually delicate little-branched stems up to 40 cm long from a somewhat woody base, scrambling to prostrate; weak stems quadrangular, with spreading long hairs usually on the lower branches and/or with short recurved teeth bent downwards in the upper parts, rarely glabrous but always with some hairs or papillae on the leaf sheath; leaves and stipules more or less equal, in whorls of 4, obovate to oblanceolate below usually becoming lanceolate to linear-lanceolate above, 4-15 mm long, acute rarely cuspidate or obtuse, with spreading long hairs mainly on the upper surface and especially along the scarcely recurved margin, spreading to reflexed later.
Inflorescences axillary, 1 or 2 at a node, with delicate peduncles usually at least twice as long as the subtending 'leaves', with pedicels at least 3 times as long as the fruit, loosely branched, with 5-15 flowers, rarely only 3-flowered; corolla yellowish-green to cream.
Fruit up to 2 mm long, with 2 reniform mericarps touching one another, each finely granulate, with scattered tubercles or recurved teeth; fruiting pedicels spreading, straight.

G. migrans, the most widespread species in the genus in S.Aust., is easily confused with G. binifolium as the difference in the length of the leaves and stipules is not striking in S.Aust. However, G. migrans is usually distinguished by its fine spreading hairs at least at the base of the plant and 5-15 flowers on a delicate inflorescence with thread-like pedicels.
