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.

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.
