Characteristics

Slender, erect, broom-like perennial shrub to c. 2 (‒3) m high, older plants and branches leafless or nearly so; stems green with protuberant petiole scars, virtually glabrous. Leaves, when present, obovate to sublinear, 8–60 mm long, 1–2.5 (‒5) mm wide. Flowers in terminal racemes 4–15 cm long (exceeding the upper foliage), predominantly purple to pinkish lilac; bracts soon caducous; pedicel 3–10 mm long; alae (wing-sepals) broadly obovate, 10–15 mm long, 7–10 mm wide, mauve (or pale pink-purplish or white) on both surfaces with c. 6 darker veins and oblique connecting veinlets; corolla subequal to sepals, keel pink to mauve sometimes with a darker apical blotch, fimbriate appendages c. 4‒5 mm long; lateral petals c. half as long as keel; style strongly curved. Capsule obcordate, c. 9‒10 mm long, c. 8 mm wide, glabrous. Seeds subcylindrical, shortly pubescent, 1‒3.5 mm long, with aril c. 1 mm long.

Perennial somewhat-branched shrub up to 2 m high. Young stems with short curly hairs, glabrous when older. Lvs all alternate, glabrous or sparsely hairy, oblanceolate, obovate or linear, obtuse to acute, mucronate, entire, subsessile, 10-40 mm long. Fls in loose, branched or simple, terminal racemes; perianth coloured pink to purple toward apex; pedicels 5-10 mm long; bracts ovate-triangular, c. 2 mm long, deciduous; 3 outer sepals elliptic to obovate, 4-5 mm long; wings petaloid, c. 10-12 mm long, ± = or > corolla; outer petals entire, c. 1/2 length of keel; keel fimbriate at apex. Capsule glabrous, c. 6-10 mm long with a marginal wing c. 1 mm wide, 1/2-⅔ length of persistent calyx wings; seeds hairy, narrow-oblong, c. 4-5 mm long; strophiole 3-lobed.
Perennial, dwarf shrub. Stems sparsely foliose or densely pubescent, rarely glabrous, 1.5-3.0 m high. Leaves linear or obovate-linear (2-20 mm wide). Flowers in terminal racemes on ultimate branchlets, papilionaceous; bracts and bracteoles 2-3 mm long. Flowering time Oct.-Feb. Fruit a laterally flattened capsule, with acute or narrowly winged margins, which open along top and bottom and expose a hairy seed in each locule. Seed: caruncle asymmetric, with odd branch less than double the length of others, silky short hairs never exceeding base of seed for > 1 mm long.
Slender-stemmed shrub, sometimes to 2 m, stems only leafy above. Leaves mostly lanceolate-elliptic. Flowers many in terminal racemes, uniformly dark purple, side petals entire, pedicels hairy.
