*1. M. sativa (L.); st. erect, racemes many-flowered, pods 

 compressed loosely spiral with 2 or 3 turns downy with adpressed 

 hairs unarmed, pedicels shorter than the calj'x or bract, leaflets 

 obovate-oblong dentate above emarginate mucronate. — B. B. 

 1 749. — St. angular when young. Pods twisted into a loose open 

 spiral, n. yellow or violet. — Hedge-banks and borders of fields, 

 scarcely naturalized. P. VI. VII. Lucerne. E. S. 



2. M. sylvestris (Fries) ; st. rather quadrangular pithy ascend- 

 ing, racemes many-flowered, pod of one flat turn annular, pedi- 

 cels shorter than the cal. longer than the bract. Its. obovate-oblong 

 dentate above emarginate mucronate. — Fl. yellow or blackish- 

 green with darker streaks. — Sandy and gravelly places in Norfolk 

 and Suff'olk. P. VI. VII. E. 



3. M. falcata (L.) ; st. usually terete nearly sohd prostrate, 

 racemes many-flowered, pod straightly sickle-shaped twisted not 

 annular, pedicels shorter than the cal. longer than the bract. Its. 

 obovate-oblong dentate above emarginate mucronate. — E. B. 

 1016. — Fl. vellow. — Sandy and gravelly places in Norfolk and 

 Suff'olk. P. VI. VII. E. 



4. M. lupnlina (L.) ; spikes many-flowered dense oval, pods 

 compressed unarmed kidney-shaped with a spiral point rugged 

 with longitudinal branched prominent veins, stip. obliquely ovate 

 slightly toothed, leaflets roundish-obovate denticulate above emar- 

 ginate mucronate. — E. B. 971 -—St. procumbent or ascending, 

 spreading widely. Pods scarcely spiral, glabrous or slightly hairy. 

 Fl. yellow. — Waste ground. A. V.— VIII. Black Medi'ck. 



5. M. maculata (Sibth.); peduncles 1 — 4-jlowered, pods com- 

 pactly spiral compressed consisting of 2 or 3 turns veined with 

 4 ridges on the edge and a central furrow, spines in 2 rows diver- 

 gent subulate cuiTed, leaflets triangular-obcordate, stip. toothed. 

 — E. B. 1616. — Leaflets with a purple spot in the centre. Edge 

 of the pods broad; spines arising from the margin and the ridge 

 next to it on each side, compressed and furrowed on both sides, 

 varying considerably in length . — On a gravelly soil. A. V. — VIII. 



6. M. minima (Lam.); peduncles 1 — 6-flowered, pods com- 

 pactly spiral consisting of 4 turns smooth with a thin edge, spines 

 in 2 rows divergent subulate hooked, leaflets obovate, stip. nearly 

 entire. — E. B. S. 26.35. — Edge of the pods with 3 ridges, the 

 central one so prominent as to be easily taken for the true mar- 

 gin, no central furrow but the central ridge common to the 2 

 rows of spines. Sides of the pods smooth. Spines varying con- 

 siderably in length and the whole plant in l^airiness. This is 

 probably Ray's Orford plant. — In sandy fields, rare. A. V. E.
