174 LEGUMINOS (Harv.) [Indigofera. 
branches filiform ; leaves sparse, petiolate, trifoliolate; leaflets elliptic- 
oblong or obovate, thin, expanded, strigose on the under surface; sti- 
pules small, subulate; racemes subcapitate, few-flowered, on long, seta- 
ceous peduncles ; calyx-segments subulate; petals glabrous; legumes 
turgid, 2-5 seeded, hispido-canescent. I. setacea, E. Mey! Comm. P95.

Root fibrous. Stems many from the crown, 1-2 feet long or more, spreading over 
the soil, alternately branched, strigose or glabrescent. Leaves an inch apart, on fili- 
form petioles, 2-3 lines long. Leaflets 2-5 lines long, varying from obovate to ellip- 
tical, sometimes glabrous on the upper side, sometimes strigillose, always rigidly 
strigose beneath, upper surface pale. Flowers small, purple. Legumes sometimes 
2 lines, sometimes 6-8 lines long. Whether this be “J. erecta” of Thunberg or not, 
that very inappropriate name is undeserving of being retained. 
21. I. procumbens (Linn. Mant. 27 1) 3; herbaceous, procumbent, pros- 
trate or running under the soil, sparsely strigillose ; branches angular, 
compressed ; leaves on longish petioles, trifoliolate ; leaflets obovate or 
rhomboid, obtuse or mucronulate, glabrescent or sparsely strigillose ; 
stipules subulate; racemes on peduncles much longer than the leaves, 
erect, elongating, many flowered ; bracts minute ; calyx-segments shortly 
subulate ; petals glabrous or downy ; legumes . . . . 2 Thunb. Fl. Cap.

Stems several inches long, lying on the ground or creeping under ground, throw- 
ing up leaves and peduncles above the soil. Pubescence variable, always scanty, 
sometimes almost absent. Petioles 4 inch to 2 inches long, erect. Leaflets in a. 4 
inch long and broad ; in 8. 3—5 lines long, 2-3 lines wide. Flowers purple, 3-4 lines 
long, in a raceme 2~3 inches long. The two varieties above indicated appear to run 
into each other ; and other varieties might be indicated equally deserving of separa- 
tion. The pedunele, for instance, is sometimes very thick and succulent, sometimes 
slender, and the calyx-segments are longer or shorter, &c. 
21. I. porrecta (E. & Z.! 1572); suffruticose, procumbent, much 
branched, thinly strigillose; branches ribbed and JSurrowed ; leaves on 
longish petioles, trifoliolate ; leaflets cuneate-obovate, or obovate-oblong, 
acute or mucronate, thinly strigillose; stipules setaceo-subulate; ra- 
cemes on long, ribbed peduncles, elongate, many flowered ; bracts mi- 
nute ; calyx cano-strigillose, its lobes setaceo-subulate ; petals pubes- 
cent; legumes terete, pendulous, several-seeded, minutely strigillose.
