Characteristics

Scarcely stoloniferous perennial; stems ± glabrous, ± solid, procumbent to ascending, woody at base. Lvs ± glabrous or sparsely to moderately hairy, sessile; leaflets linear, linear-lanceolate to narrowly obovate, acute to acuminate, cuneate at base, (3)-5-15-(18) mm long, with inconspicuous lateral veins. Peduncles much > lvs, up to 90 mm long. Infl. (1)-2-4-(6)-flowered. Calyx ± glabrous or sparsely to moderately hairy; calyx teeth ± equal, narrowly triangular, < tube. Corolla yellow, sometimes tinged or wholly reddish orange, 9-12 mm long; keel strongly arched with a fairly long, often somewhat incurved beak. Pod straight, rounded, not winged, 15-35 × 1.5-3 mm; seeds c. 1.5 mm diam.

Much like no. 1 [Lotus corniculatus L.], and not always sharply distinct exomorphically, but less robust and typically in drier, more difficult habitats; lfls mostly linear or lance-linear and 2.5–5+ times as long as wide; fls mostly (1)2–5 together; cal-tube 1.8–2.8 mm; cor 7–10(–12) mm, yellow, drying orange; 2n=12. Native of Europe, widely intr. in U.S., but more common in arid regions. June– Aug. (L. corniculatus var. tenuifolius)
