Morphological description. Centrosema brasilianum is commonly described as a prostrate-trailing to twining, perennial, herbaceous legume. However, some erect and semi-erect forms were identified. Similarly, the ability to form adventitious roots on trailing stems varies among studies. Leaves are trifoliolate, leaflets elliptical-oblong to lanceolate, sometimes ovate, 3.3-6.6 cm long, 1.5-3.6 cm wide. Flowers usually in racemes of 2-5 flowers, sometimes solitary. Bracteoles glabrous or pubescent, 3-13 mm long, 12-17 mm long and 5-10 mm wide, ovate and flat or cupped. Peduncles in leaf axils, 4-30 mm long. Papilionate flower, usually violet, violet-blue or red-lilac, in rare cases also white or purple. Variation in colour intensity within one accession can occur, suggesting some degree of outcrossing.

Morphological description. C. ternatea is a vigorous, strongly persistent, herbaceous perennial legume; stems fine twining, sparsely pubescent, suberect at base, 0.5-3 m long. Leaves pinnate with 5 or 7 leaflets; petioles 1.5-3 cm long; stipules persistent, narrowly triangular, 1-6 mm long, subulate, prominently 3-nerved; rachis 1-7 cm long; stipels filiform, to 2 mm long; leaflets elliptic, ovate or nearly orbicular, 1.5-5 cm long, 0.3-3 cm wide, with apex acute or rounded, often notched, and base cuneate or rounded, both surfaces sparsely appressed pubescent. Flowers axillary, single or paired; colour ranges from white, mauve, light blue to dark blue; pedicles 4-9 mm long, twisted through 180º so that the standard is inverted. Bracteoles persistent, broadly ovate or rounded, 4-12 mm long. Calyx 1.7-2.2 cm long with a few fine hairs; tube campanulate, 0.8-1.2 cm long; lobes triangular or oblong, 0.7-1 cm long, acute or acuminate. Standard obovate , funnel-shaped, 2-5.5 cm long, 2-4 cm wide, notched or rounded at apex, blue with a pale yellow base, or entirely white, a few fine hairs at apex. Pods linear-oblong, flattened, 4-13 cm long, 0.8-1.2 cm wide, with margins thickened, and style persistent, sparsely pubescent when mature, pale brown, dehiscent when dry. Seeds 8-11/pod, oblong , somewhat flattened, 4.5-7 mm long, 3-4 mm wide, olive brown to almost black, shiny, often mottled, minutely pitted; 23,000 seeds/kg. Morphology can vary with different growing conditions. Cv. Milgarra, which has no significant distinguishing morphological characters, is normally towards the upper end of the size ranges of descriptions in the taxonomic literature.
