Vicia floridana
Proc. Amer. Acad. Arts 14: 292. 1879.
Herbs perennial. Stems sprawling or climbing, filiform, 3–8 dm. Leaves 3–5 cm; tendrils simple; stipules much smaller than leaflets, semisagittate, without nectariferous patch; leaflets 2–6, blades usually broadly elliptic to oblong or oblanceolate, sometimes linear, 7–18 × 2–8 mm, apex obtuse, surfaces glabrous. Inflorescences 2–8-flowered, 2–5 cm, shorter to longer than subtending leaf rachis. Flowers 5–6 mm; calyx base symmetric, lobes equal, much shorter than tube; corolla white to bluish, banner pandurate, blade equal to claw, glabrous; style compressed adaxially, pubescent apically. Legumes brown to black, broadly oblong, 8–15 × 3–5 mm, oblique-tipped, glabrous; stipe to 1–2 mm. Seeds 1 or 2, purplish black, compressed-globose, 3 mm diam.; hilum encircling 1/2–3/4 circumference of seed.
Phenology: Flowering Apr–May.
Habitat: Moist soils, ditches, roadsides.
Elevation: 0–100 m.
Discussion
Vicia floridana is distinguished from V. acutifolia by the broader leaflets (elliptic to lanceolate versus linear) and shorter (8–15 mm versus 20–25 mm) fruits.
