Cassia capensis var. flavescens (E.Mey) Vogel , Syn. Gen. Cassiae 64 (1837); Gordon-Gray in F.S.A. 16(2): 99 (1977).

TYPE: SOUTH AFRICA. Eastern Cape Province, Amabele, De Vries 51A (neotype: PRE!, designated here).

Note: The original Drege collection (South Africa, Transkei [Eastern Cape], between Gekau (Geua) and Bashee Rivers [Mbashe], Drege s.n. (B†?)) cited by Meyer could not be located and so we here designate a collection of De Vries as neotype as it closely matches the original description and is the most complete specimen.

Perennial herbs, to 0.6 m high. Stems prostrate, decumbent or erect, single or few stemmed, arising from woody rootstalk, branching on the upper half, with long, straight or curved greyish or yellow hairs. Leaves with circular extrafloral nectaries, attached with very small stalk, sometimes lacking. Leaflets 11–24-jugate. Pedicels at flowering 18–40 mm long.

Diagnostic Characters — Chamaecrista capensis var. flavescens was established within C. capensis , which is distinguished from C. capensis var. capensis by erect stems that are branching in the upper half, with short and long patent hairs intermixed, greyish or yellow indumentum, and extrafloral nectaries that are raised on a small stalk or sometimes lacking.

Distribution and Ecology — Chamaecrista capensis var. flavescens is widespread in KwaZulu-Natal from Pietermaritzburg to Port Edward, extending to Lady Frere to Peddie in the Eastern Cape ( Fig. 6 ). Grows in grassland in well drained sandy soil, at elevations below 1300 m. Flowering from October–March.
