INDIGOFERA, LEGUMINOSÆ. 201 
§ 7. Leaves petioled: racemes sessile, short, not so long as the petiole, many-flow- 
ered, dense: pedicels much shorter than the calyx: legumes linear, nearly 
straight, deflexed, several (6-20) times longer than broad, slightly compressed : 
sutures thickened—Brachystachye. 
628. (12) I. trifoliata (Linn. :) suffruticose, branched ; branches slender, 
iffuse, prostrate but ascending at the extremities, glabrous and terete to- 
wards the base, two-edged and pubescent upwards: leaves on longish pe- 
tioles, palmately trifoliolate ; leaflets cuneate-obovate, pubescent on both 
sides, glandular underneath: racemes sessile, shorter than the petioles, dense, 
many-flowered ; flowers minute : calyx-segments long and subulate : legumes 
straight, deflexed, slightly compressed, somewhat torulose, with a prominent 
almost winged nerve on each side of the sutures, particularly the seminife- 
Tous one ; seeds 6-8, cylindrical, truncated at both ends.— Linn. / amen. 4.

Although the above vary slightly in appearance, they constitute in our 
Opinion but one species : according to the soil the leaves are cuneate-oblong 
or obovate ; to the narrower leaved state may be referred J. trifoliata, Linn., 
di prostrata, Willd., T. Oriæensis, Roxb., I. multicaulis, DC. (with which J. 
ylla, Gr. is identical), and part of T. congesta, a, Gr. ; to the broader 
leaved the remainder of J. congesta, I. canescens, Gr., and I. Leschenaultit. 
I. peregrina, DC., appears to be a state in which more of the upper flowers in 
each raceme have become abortive than usual, and seems to be represented 
in the figure of Plukenet above quoted. J. Orizensis of Heyne in Wall. L. 
n. 5471. b. differs in having considerably larger flowers than any of the other 
Specimens, but does not form a distinct species. 
629. (13) I. rviflora (Heyne:) erect, branched, all over whitish with 
short Soest tee ae: na below, angled upwards: leaves pe- 
tioled, pinnated ; leaflets 3-4 pairs, oblong-linear: racemes sessile, dense, 
many-flowered, about the length of the petiole: flowers numerous, minute, 
© Upper ones caducous : calyx-segments subulate: legumes linear, straight 
except at the point, deflexed, compressed, pubescent, 15-20-seeded: seeds 
cylindrical, truncated at both ends.—Heyne! in Wall. ! L. n. 5457 ; Wight!

8 9. Leaves petioled, pinnated, sometimes reduced to one or two leaflets : racemes 
sessile, elongated, many-flowered ; pedicels very short : calyx-segments usually 
short and broad : legumes linear, several times longer than broad, nearly te- 
rete or slightly compressed : sutures thickened.— T'inctorie.
