Cult. None of the species are worth cultivating except in 

 botanical gardens. They are all easily increased by seeds, 

 which only require to be sown in the open border in spring. A 

 dry light soil suits them best. 



LXX. TRIFO'LIUM (from Ires, three, and folium, a leaf; 

 all the species of the genus have trifoliate leaves, or each leaf is 

 composed of 3 leaflets ; the Greeks call it rpipvXXoj' ; the French 

 trefle ; and the English trefoil or clover). Tourn. inst. 404. t.

Trifolium, spec. Lin. 



LIN. SYST. Dladelphla, Decandrla. Calyx tubular (f. 32. .), 

 permanent, glandless, 5-cleft (f. 32. a.) ; segments subulate. 

 Carina shorter than the wings and vexillum. Stamens diadel- 

 phous (f. 32. &.). Legume small, hardly dehiscent, usually ovate, 

 1 -2-seeded, shorter than the calyx, and covered by it, rarely 

 oblong, and containing 3-4 seeds, in which case it exceeds the 

 calyx a little. Herbs. Stipulas adnate to the petioles. Leaves 

 usually trifoliate, rarely with 5 leaflets. Flowers disposed in 



di use heads or spikes, bracteate, purple, white, or cream-coloured. 

 Petals in the greater part of the species joined together at the base. 

 This genus includes the most valuable herbage plants adopted in 

 European agriculture, the white, red, and yellow clover. Not- 

 withstanding all that has been said of the superiority of lucern to 

 clorer, and of the excellence of saintfoin and various other legu- 

 minous plants, yet the red clover for mowing, and the white 

 species for pasturage, are, and probably ever will be, found to 

 excel all plants in these respects. The yellow clover, and the 

 cow or meadow clover are also in cultivation but are inferior to 

 the white and red clover. 



SECT. I. LAGOFUS (from \a-yioc, logos, a hare, and wove, pous, 

 a foot ; in reference to the soft villous heads of flowers, which 

 have been compared to the softness of a hare's foot). Ser. mss. 

 in D. C. prod. 2. p. 1 89. Flowers spicate ; spikes oblong, 

 bractless at the base. Calyx very villous, not inflated after 

 flowering. 



1 T. ANGUSTIFOLIUM (Lin. spec. 1083.) stem erect; leaflets 

 linear-lanceolate, very acute, ciliated ; stipulas very long, narrow, 

 subulate at the apex ; spike solitary, terminal, between conical 

 and oblong in shape ; calyx ribbed, glandular, and pilose ; seg- 

 ments setaceous, spinescent at the apex, hardly exceeding the 

 monopetalous corolla, lower segment longest ; seeds egg-shaped, 

 smooth, bay-coloured. 0. H. Native of the south of Europe 

 and the extra-tropical parts of the south of Africa, ex Burch. 

 cat. geogr. no. 286. Sturm, deutsch. fl. 1. fasc. 16. Savi, obs. 

 p. 58. Barrel, icon. 698. Flowers pale rose-coloured.

 PI. 1| foot. 



2 T. INTERMEDIUM (Gussone, cat. 1821. p. 82. in a note, 

 p. 14. but not of Lapeyr.) plant pilose; stem diffuse ; leaflets 

 lanceolate, oblong ; spikes villous, between conical and oblong 

 in shape ; segments of the calyx setaceous, and nearly equal, 

 but not spinescent at the apex ; corolla hardly exceeding the 

 calyx. O- H. Native of Italy, on sandy hills. Corolla white. 

 Calyx striated, the segments terminated by fascicles of hairs. 

 The rest of the plant appears as if it were a hybrid between T. 

 angnstij olium and T. arvense.

 PI. to 1 foot. 



3 T. PURPU V REUM (Lois. fl. gall. 484. t. 14.) stem erect; 

 leaflets linear-lanceolate, acute, quite entire, ciliated ; stipulas 

 narrow, somewhat setaceous at the apex ; spikes ovate-oblong, 

 terminal, solitary ; calyx ribbed, glandular, and pilose ; the seg- 

 ments setaceous, much shorter than the corolla, which is perhaps 

 monopetalous, the lower segment longest. O- H. Native about 

 Montpelier, Florence, and of the Levant. Savi, obs. p. 60. 

 Flowers purple. 



Purple-fiowered Hare's-foot Trefoil. Fl. June, July. Clt. 

 1816. PI. 1 fiot. 



4 T. RUBENS (Lin. spec. 1081.) stem erect, straight; leaflets 

 oblong, very blunt, and quite smooth, denticulated ; stipulas 

 very long and very broad, lanceolate at the apex ; spikes ter- 

 minal, usually twin ; calyx very much striated, glandless, with 

 the segments setaceous and very short, the lower segment 

 longest, but hardly equal in length to the monopetalous corolla ; 

 seeds egff-shaped, smooth ; radicle rather prominent. I/ . H. 

 Native of Europe, on mountains, in meadows, and on the mar- 

 gins of woods. Sturm, deutsch. fl. 1. fasc. 15. Savi, obs. p. 

 55. Mart. fl. rust. t. 9. Jacq. aust. 4. p. 385. Flowers dark 

 red. An elegant plant.
