description: <i>4.2. L. brevicarpa</i> <i>L. brevicarpa</i> M.M. le Roux and B.-E. van Wyk, sp. <i>nov. L. ambiguae sepiariae similes sed leguminibus brevibus ovatis pauciseminalibus (in L. ambigua et L. sepiaria lineares multiseminales) differt</i>. Type: South Africa, Pakhuis Pass [3219 AA], <i>Le Roux and Van Wyk 5</i> (NBG, holotype; BOL, K, PRE, S, isotypes). Erect, glaucous suffrutex, up to 0.8 m in height. <i>Leaves</i> simple, acicular, articulated near the middle; leaf density 3–6 per 10 mm length of stem. <i>Inflorescences</i> 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. <i>Calyx</i> 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. <i>Standard</i> ovate to orbicular, 10–13 × 6.5–7.5 mm; apex obtuse; claw 2.0– 2.5 mm long. <i>Wings</i> oblong, longer than the keel, 9–11 × 3.5–4.0 mm, with 14–18 rows of sculpturing; apex obtuse; claws ± 3 mm long. <i>Keel</i> rostrate, 8–9 × ± 4 mm, usually without pockets; claws 3.0– 3.5 mm long. <i>Pistil</i> short-stipitate; ovary 8–10 × 0.7– 0.9 mm long, oblong; ovules few (6–10); style 3–5 mm long, curved upwards. <i>Pods</i> ovoid, up to 13 × 5 mm; indehiscent; terete; fruit wall thick, spongy. <i>Seeds</i> reniform–orbicular, 3.0 × 2.2 mm, indistinctly rugose, pale brown, mottled dark brown to black; hilum dark brown (Fig. 7). <i>4.2.1. Diagnostic characters</i> <i>L. brevicarpa</i> is similar to <i>L. ambigua</i> and <i>L. sepiaria</i>, but differs markedly in its short, ovate, few-seeded pods (linear and many-seeded in <i>L. ambigua</i> and <i>L. sepiaria</i>). In <i>L. brevicarpa</i> the wings are longer than the keel and the bracts are less caducous than in <i>L. sepiaria</i> (which has wings that are shorter than the keel) (Fig. 7). <i>4.2.2. Distribution and habitat</i> <i>L. brevicarpa</i> has a localised distribution and is restricted to altitudes above 400 m in the Bokkeveld and Cedarberg Mountains (Fig. 8), where it is locally common in deep sandy soil on disturbed roadsides. <i>4.2.3.
