Glycine clandestina (Twining Glycine / Coast Glycine)

Glycine clandestina, commonly known as Twining Glycine or Coast Glycine, is a graceful Australian native climbing vine that adds a soft, textured layer to gardens and natural landscapes. Its twining, non-stoloniferous stems are covered with fine, soft hairs in shades of white, grey, or rusty brown, giving it a delicate, silvery appearance in sunlight.

The leaves are palmately trifoliate and dimorphic: upper leaflets are linear to narrow-elliptic or oblong-lanceolate, 1–8 cm long and 2–10 mm wide, while lower leaflets (common in subalpine populations) are oblanceolate to broad-obovate or nearly circular, 0.5–3 cm long and 2–8 mm wide. Leaf surfaces vary from sparsely hairy to almost glabrous, and stipels are absent on the median petiolule.

Flowering occurs in racemes of 4–18 flowers, slightly longer than the leaves. Each flower features a mauve to rose-purple or occasionally white standard petal, 5–10 mm long, producing a subtle yet attractive display in spring and summer. Following flowering, straight pods 1.2–5.3 cm long and 2.5–4 mm wide develop, containing 4–12 seeds, and are sparsely hairy to glabrous.
