T. hýbridum, L. (Alsike C.) Resembling T. repens, but the stems erect or ascending, not rooting at the nodes; flowers rose-tinted.—Becoming common. (Nat. from Eu.)
[*][*][*] Flowers short-pedicelled in close heads, reflexed when old; corolla yellow, persistent, turning dry and chestnut-brown with age, the standard becoming hood-shaped; annuals, fl. in summer.
T. agràrium, L. (Yellow or Hop-C.) Smoothish, somewhat upright (6–12´ high); leaflets obovate-oblong, all three from the same point (palmate) and nearly sessile; stipules narrow, cohering with the petiole for more than half its length.—Sandy fields and roadsides; N. Scotia to Va.; also in western N. Y. (Nat. from Eu.)
T. procúmbens, L. (Low Hop-C.) Stems spreading or ascending, pubescent (3–6´ high); leaflets wedge-obovate, notched at the end, the lateral at a small distance from the other (pinnately 3-foliolate); stipules ovate, short.—Sandy fields and roadsides, common.—Var. mìnus, Gray, has smaller heads, the standard not much striate with age. (Nat. from Eu.)
10. MELILÒTUS, Tourn. Melilot. Sweet Clover.
Flowers much as in Trifolium, but in spike-like racemes, small; corolla deciduous, free from the stamen-tube. Pod ovoid, coriaceous, wrinkled, longer than the calyx, scarcely dehiscent, 1–2-seeded.—Annual or biennial herbs, fragrant in drying, with pinnately 3-foliolate leaves, leaflets toothed. (Name from μέλι, honey, and λωτός, some leguminous plant.)
M. officinàlis, Willd. (Yellow Melilot.) Upright (2–4° high); leaflets obovate-oblong, obtuse; corolla yellow; the petals nearly of equal length.—Waste or cultivated grounds. (Adv. from Eu.)
M. álba, Lam. (White M.) Leaflets truncate; corolla white; the standard longer than the other petals.—In similar places. (Adv. from Eu.)
11. MEDICÀGO, Tourn. Medick.
Flowers nearly as in Melilotus. Pod 1–several-seeded, scythe-shaped, incurved, or variously coiled.—Leaves pinnately 3-foliolate; leaflets toothed; stipules often cut. (Μηδική, the name of Lucerne, because it came to the Greeks from Media.)
