Glycine clandestina

Glycine clandestina, the twining glycine, is a slender herbaceous to semi-woody perennial vine in the family Fabaceae widely distributed across Australia, occurring in all states and territories, with disjunct populations in New Zealand, New Caledonia, and parts of southeast Asia and the Pacific. Plants produce wiry twining or trailing stems up to 1-2 m long from a deep persistent rootstock, often forming tangled mats among grass and low shrubs. Leaves are alternate and pinnately trifoliate, with three narrowly linear to lanceolate or elliptic leaflets 1-7 cm long and 1-10 mm wide, glabrous to softly hairy beneath; leaflet shape is highly variable across populations and several forms have been informally recognized. The inflorescence is a slender axillary raceme bearing 2-12 small pea-flowers, each 6-10 mm long, with pink to mauve or purplish standards and paler keel and wing petals. Flowering occurs through much of the year in suitable climates. The fruit is a narrow flat hairy legume 15-35 mm long containing several small oblong seeds. The species inhabits open Eucalyptus woodlands, dry sclerophyll forest, grasslands, and roadside verges, generally on light free-draining soils.
