long, coriaceous. Ms. large, dull yellow. Apr., JH. Each plant forms a globu- 

 lar mass which when dry, breaks away and rolls about with the wind frightening 

 horses ; hence called horse-devils.

 somewhat racemed at tho ends of the branches. Fla., La.

 soils, Can. and U. S. St. very bushy, about 2f high. Lfts. about 7" by 4 to 6", 

 cmarginate; petiole 1 to 2" long. Fls. 6 to 12 or more in each raceme. Petals

 Jl. Sept. 



11 B. Lecontii Torr. & Gr. Somewhat pubescent; Ivs. short- petioled ; Ifts. 

 obovate-oblong ; pedicels longer than the fls., with two bractlets ; bracts per- 

 sistent kg. short-stiped ; branches, stipules and racemes as in No. 10. Fla. and 



S. Ga. Does not turn black in drying. May.

 short and short-stalked ; stip. and bracts minute, caducous ; fls. nodding, on pedicels 

 shorter than the corolla; leg. large, globular, and much inflated. Near Quincy, 

 Fla. Fls. and Ivs. nearly as large as in No. 9. Mature pods 1^' diam. Does not 

 blacken in drying. May. 



13 B. mollis MX. Minntely-hoary-pubescent, sparingly branched ; petioles half 

 as long as the cuneiform-oblanceolate Ifts. ; stip. lanceolate, as long as the petioles ; 

 pedicels as long as the fls., in terminal racemes. In mountain woods, N. Car. 

 and Tenn. (Lookout Mt M Chattanooga.) A fine, bright-flowered species, l$f

12. FA V BA, Moench. HORSE BEAN. COFFEE BEAN. Flowers as in 

 Vicia, but the seeds oblong, with a long scar (hilum) on the narrower end, 

 and leathery, tumid legumes. Lvs. equally pinnate, with the tendril 

 obsolete (in the following species). Peduncle shorter than the flowers. 



F. vnlgciris Mcench. St. rigidly erect, with very short axillary racemes; Ifls. 

 2 to 4, oval, entire, mucronate or acute; (tendrils obsolete by cultivation;) stip. 

 semisagittate, dentate at base. Native of Egypt. Frequently found in gardens, 

 but not so much admired for the table as formerly. Fls. white, with a large black 

 spot on each of the ala3. Leg. torulous. Sds. very large, with a large hilum at 

 one end. (Vicia Faba L.) 



13. CI'CER arieti num, the CHICK PEA, rarely cultivated may be 

 readily known by its serrated leaflets, a character quite strange in this 

 Order. 



14. PI 'SUM, L. PEA. (Celtic pis, Lat. pisum, Eng. pea, Fr. pois.) 

 Calyx segments leafy, the upper two shortest ; vexillum large, reflexed ; 

 stamens 10, diadelphous (9 and 1) ; style grooved on the back, villous 

 and stigmatic on the inner side ; legume oblong, tumid, many-seeded ; 

 seeds globous, with an orbicular hilum. Herbaceous, climbing. Lvs. 

 abruptly pinnate, ending with branching tendrils. 



P. sativum L. Lfts. ovate, entire, usually 4; stip. ovate, semi-cordate at base, 

 crenate; ped. several-flowered. One of the most valuable ofleguminous plants, 

 smooth and glaucous. St. 2 to 5f long, nearly simple, climbing by tendrils. Lfts. 

 2 to 3' long, as wide, obtuse, mucronate, stip. rather larger than the leaflets. 

 Fls. two or more, on axillary peduncles, large, white. This plant has been cul- 

 tivated from tirhe immemorial, so that its native country is unknown. There 

 are many varieties. 



15. LATH'YRUS, L. Calyx campanulate, the two upper sepals shortest; 

 stamens 10, diadelphous (9 and 1) ; style flat, dilated above, ascending,
