point, the outermost pair much smaller than the other three. Flowers 

 very numerous, in moderately dense short-peduncled terminal racemes 

 reaching 5-6 in. long, 15-18 line.s broad. Bracts minute, setaceous. 

 Pedicels 1^-2 lines, finely grey-silky '. Calyx 2|-3 lines, the lanceo- 

 late-deltoid teeth shorter than the tube. Corolla bright uniform 

 yellow, more than twice the calyx. Pod distinctly-stalked, linear, 

 15-18 lines long, 3-3 J broad, at first finely downy, glabrescent, 30-40- 

 seeded.

 Very near C. striata, except in the number of leaflets. 



4. LUPINTJS, Linn. ; Benth. et Hook. f. Gen. Plant, i. 480. 



Calyx deeply 2-lipped, upper lip entire or emarginate in our species, 

 lower slightly 3-toothed. Standard ovate, wings large, oblong, includ- 

 ing the small upcurved rostrate keel. Stamens united in a close tube. 

 Ovary sessile, oo -ovulate ; style slender, upcurved, glabrous ; stigma 

 capitate ciliate. Legume compressed, silky, septate between the seeds, 

 2-valved. 



A large genus, almost entirely American. A few annual species with digitate 

 leaves inhabit the shores of the Mediterranean, of which one extends into Tropical 

 Africa. 



1. Ii. Termis, Forsk.; DC. Prodr. ii. 407. Stem 12-18 in. high, 

 not much branched, erect, silky. Petioles 1J-2 in. long, slender, 

 erect. Leaves digitate, with 5-7 sessile oblanceolate leaflets about 

 1 in. long, 2-4 lines broad, the under side silky. Flowers in lax 

 4— 12-flowered sessile racemes. Calyx silky, campanulate, 3—4 lines 

 deep, teeth reaching halfway down. Corolla more than twice as long 

 as the calyx ; the standard blue round the border, white within, the 

 wings white, the keel white with a dark blue spot. Pod 3 in. long, 

 J-| in. thick, mucronate, thinly silky. — Guill. et Perr. Fl. Seneg. 224.

 Very near L. albus, L., and perhaps not distinct from it. 



5. ABGrYROLOBIUM, Eck. et Zeyh.; Benth. et Hook. f. Gen. 

 Plant, i. 480. 



Calyx deeply bilabiate, two upper teeth free in all the Tropical 

 African species, three lower ones more or less (in one species entirely) 

 connate. Standard suborbicular, wings free, keel slightly upcurved, 

 not rostrate. Filaments usually but not invariably united downwards 

 in a closed tube. Ovary sessile, linear, oo -ovulate ; style upcurved, 

 glabrous, stigma oblique. Pod linear, flattened, faintly torulose. 

 — Undershrubs or herbs with digitately trifoliolate leaves. 



A genus of moderate size, with its head-quarters at the Cape, outlying representa- 

 tives reaching India, Siberia, and Central Europe.
