Plant Description
Spotted medick is a native, prostrate or sprawling herb that normally grows about 2–6 cm tall. An annual, it is often found low to the ground mixed in with the grass. The plant is found growing in moist stream banks, grasslands, places, thin pasture, lawns, meadows and fields and disturbed areas including waste lots and roadsides. The plant grows in light, sandy and gravelly soils, particularly near the coast. Stems are decumbent or spreading, longitudinally ridged, sparsely hairy, hairs are simple and multicellular-glandular. The plant has one leaf per node along a hairy stem that is often red-streaked.
Leaves
Leaves alternating along the stems are pinnately compound, with 3 leaflets each 0.4-4 cm long and 5–45 mm wide. Margins are toothed towards the tips. Upper surface is hairless, usually with a dark patch near the middle, lower surface is sparsely appressed-hairy, tips squared off or notched with a terminal tooth, stipules strongly toothed and hairy on lower surface.

Flowers
Inflorescence of 1 to 5 pea-like flowers is in a reduced, axillary raceme on a stalk 1-3 cm long on fairly short peduncles arising from the leaf axils. The stalks are shorter than the leaves. Corollas are pea-like, yellow, about 5 mm long, the banner erect, much longer than the wings and keel. Calyces are sparsely white-hairy, 2-3 mm long, the lanceolate, long-pointed teeth slightly longer than the tube. Flowering normally takes place in between April and August.
Fruits
Fertile flowers are followed by pod spirally coiled through 3 to 5 spirals, round, 4-8 mm in diameter, the outer margins narrowly keeled, spineless, or with two rows of divergent prickles up to 2.5-3.5 mm long, somewhat curved to nearly straight with short hook at tip, aging pale brown. Seeds are kidney-shaped, 3 mm long and 1.5–1.8 mm wide, glossy reddish brown, with stalked hilum close to midpoint and adjacent micropyle just outside the hilum.
Other Facts
- For millennia people have used those plants for soap.
- They’ve also been used as a fish poison making it easy to catch the fish.
- A cover crop controls soil erosion and replenishes nutrients.
- It is planted after the primary cash crop has been harvested.
- The plant is an excellent green manure and has been the subject of studies about its use as a cover crop in large-scale farming.
