Dense twining shrubs that often form mounds as wide as high, usually at least 1 x 1 m and often twice these dimensions, scrambling and eventually clearly twining through surrounding vegetation, new stems not warty/tuberculate. Leaves mainly towards the branchlet apices, alternately arranged towards the branchlet bases and on twining shoots, but clustering in different sizes on short shoots and towards the apices, sessile, linear filiform and rather ‘wispy’ and held at all angles to the stem, 40–50 mm long, 1–2 mm wide; margin recurved. Inflorescences corymbs of at least 3–5 flowers subtended by a leaf-like bract; terminal and terminal on short shoots, rachis to 30 mm long and flowers held well above the leaves, pedicels and peduncles to 20 mm long, purple. Sepals narrow-triangular, to 3 mm long, margins incurving, mostly white around a purple centre, slightly ciliate on margins but otherwise glabrous. Petals narrow elliptic, 12–20 mm long, 5–8 mm wide, deep blue on the inner surface, paler on the outer. Stamens with anthers cohering, grouped together like the fingers of a hand facing petal break; filaments to 3–4 mm long, thin, ribbony, flared, deep purple blue; anthers cohering apically and recurving pulling the apical slits apart to act like pores; anthers gold, to 7 mm long, sagittate with a basal sinus of 1 mm; pollen gold. Pistil mauve, quite glabrous, with the ovary longer than the curving style, little stigmatic development or cleft. Fruit to 12 mm long containing numerous seeds on longish peg-like funicles. Seeds angular reniform, glossy, not arillate.
