Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Slender glabrous subshrub to c. 60 cm high; stems simple or few-branched, smooth, arising annually from a short woody rhizome, leafy throughout or in c. lower two-thirds (rarely almost leafless). Leaves oblanceolate to linear, 8–25 mm long, 1–5 mm wide, thickish, flat or margins slightly recurved. Flowers blue, in a terminal raceme; pedicels 2–3.5 mm long; sepals free, the outer 3 obovate, 2–3 mm long, the adaxial one slightly pouched at base, wings obovate, c. twice as long as sepals or more, keel hooded and yellow at apex, with 2 lateral subapical pouches, c. 3 mm long; upper petals mauve, oblong, pointed at apex, shortly exceeding keel and united with it to c. midway. Capsule obovate or cuneate, long-tapered to base, 6–7.5 mm long, truncate or shallowly 3-toothed at apex; seeds plumply ovoid, 1–2 mm long, pubescent all over, with longer silky hairs c. 5 mm long around the margin. Flowers Oct.–Feb.

Some plants of C. calymega from the north-west are virtually leafless (and have in the past been referred to C. defoliatum). This condition seems to be related to rapid growth after fire.
