Information
Decumbent to erect, divaricately branched; hairs subappressed to spreading, often yellow. Leaflets mostly 8–20 × 3–8 mm, oblanceolate to elliptic-obovate, usually glabrous above; lateral nerves ± obscure beneath; petioles 3–10(12) mm long. Primary racemes terminal and leaf-opposed, 2–8(12) cm long, 3–8(12)-flowered, determinate; 1–2-flowered supplementary inflorescences often not sharply differentiated, produced at or near ends of short shoots that have mostly grown out to some extent; bracts 1–2 mm long. Keel 7–13 mm long.

Notes
Typically from high ground west of Lake Malawi across to the Ufipa Plateau. Plants from lower down round Lakes Tanganyika and Mweru tend to be more robust, with more contracted short shoots, whitish hairs and large flowers, so that they are morphologically less dissimilar from the more southerly subspecies. Richards 9426A (K) from Lake Mweru, Kafulwe, is decidedly anomalous, with tufts of small leaves (like subsp. forbesii) and short axes bearing the supplementary inflorescences. Compared with Richards 9472 (K) from the same locality it appears to be just a depauperate form of this subspecies, but morphologically it seems more like an odd form of subsp. forbesii.
