4.2. L. brevicarpa View in CoL View at ENA

L. brevicarpa M.M. le Roux and B.-E. van Wyk View in CoL , sp. nov. L. ambiguae sepiariae similes sed leguminibus brevibus ovatis pauciseminalibus (in L. ambigua View in CoL et L. sepiaria lineares multiseminales) differt.

Type: South Africa, Pakhuis Pass [3219 AA], Le Roux and Van Wyk 5 ( NBG, holotype ; BOL, K, PRE, S, isotypes) .

Erect, glaucous suffrutex, up to 0.8 m in height. Leaves simple, acicular, articulated near the middle; leaf density 3–6 per 10 mm length of stem. Inflorescences terminal, 220– 280 mm long; rachis furrowed; flowers numerous, relatively dense (5–7 per 10 mm length of rachis), intermediate in size (8–11 mm long); pedicel 2–3 mm long; bract narrowly lanceolate, acuminate, 4–6 mm long; bracteoles narrowly triangular to lanceolate, acuminate, up to 2 mm long. Calyx 3.5–5.5 mm long, tube 2.5–3.0 mm long, lobes 1.5–2.5 mm long; subequally lobed but the upper lateral sinuses much wider than the medial sinus and lower lateral sinuses; lobes deltoid, tips minutely pubescent inside. Standard ovate to orbicular, 10–13 × 6.5–7.5 mm; apex obtuse; claw 2.0– 2.5 mm long. Wings oblong, longer than the keel, 9–11 × 3.5–4.0 mm, with 14–18 rows of sculpturing; apex obtuse; claws ± 3 mm long. Keel rostrate, 8–9 × ± 4 mm, usually without pockets; claws 3.0– 3.5 mm long. Pistil short-stipitate; ovary 8–10 × 0.7– 0.9 mm long, oblong; ovules few (6–10); style 3–5 mm long, curved upwards. Pods ovoid, up to 13 × 5 mm; indehiscent; terete; fruit wall thick, spongy. Seeds reniform–orbicular, 3.0 × 2.2 mm, indistinctly rugose, pale brown, mottled dark brown to black; hilum dark brown ( Fig. 7 View Fig ).

4.2.1. Diagnostic characters

L. brevicarpa is similar to L. ambigua and L. sepiaria , but differs markedly in its short, ovate, few-seeded pods (linear and many-seeded in L. ambigua and L. sepiaria ). In L. brevicarpa the wings are longer than the keel and the bracts are less caducous than in L. sepiaria (which has wings that are shorter than the keel) ( Fig. 7 View Fig ).

4.2.2. Distribution and habitat

L. brevicarpa has a localised distribution and is restricted to altitudes above 400 m in the Bokkeveld and Cedarberg Mountains ( Fig. 8 View Fig ), where it is locally common in deep sandy soil on disturbed roadsides.
