. Rheed. Mal. 9. t. 36, is referred by Lamarck to his I. hedysaroides, which 
is certainly not distinct from JI. trita; ‘but the habit is considerably at 
variance ; if of this genus, the long pedicels rather point towards our J. 
pedicellata. J. trita is a most common plant, found in all soils and situa- 
tions, and, like all similarly situated plants, presents individual variations 
that might be esteemed distinct species if examined separately, but which, 
when viewed collectively, afford no permanent characters. 
637. (21) I. marginulata (Graham :) shrubby, diffuse, sparingly sprinkled 
with very short whitish pubescence ; branches terete, slender: leaves pinna- 
ted ; leaflets 1—2-pairs, opposite, elliptic-obovate, the terminal one the largest: 
stipules subulate, patent: racemes longer than the leaves, sessile, many- 
flowered: flowers very small, most of them caducous: calyx-segments long 
and subulate: legumes few, scattered on the rachis, linear, nearly quite 
straight, slightly drooping, obscurely 4-angled, many-seeded : sutures thick- 
ened.—Graham ! in Wall.! L. n. 5467 ; Wight! cat. n. 865.—— Dindygul 
638. (22) I. flaccida (Koen. :) suffruticose, sparingly covered with adpressed 
short hairs: stems and branches usually weak, the former terete, the latter j 
angled: leaves pinnated; leaflets 2-3-pair, opposite, oval, acute, bristle- 
pointed : stipules long, setaceous, erect: racemes peduncled, elongated, twice 
the length of the leaves: flowers small, recurved, rather distant: calyx-seg- 
ments long and subulate: legumes scattered on the lower half of the rachis, 
drooping, ong-linear, slender, 4-angled, pointed, many-seeded.— Roab. ! ka

This differs from the last by the peduncled racemes, and legumes twice T 
long in proportion to their breadth. 
* 639 (23) I. Kleinii (W. & A.:) herbaceous, procumbent : stems terete, 
glabrous below, sprinkled with adpressed hairs above: leaves pinnated 5 
leaflets alternate, about 9, obovate-oblong, glaucous and strigose beneath. 
stipules lanceolate, subulate at the point: racemes peduncled, equal to the 
leaves, many-flowered: flowers small: calyx deeply 5-cleft ; segments ec 
late: legumes crowded, imbricately reflexed, straight, linear, 4-angled, WI 
a subulate rigid straight point: seeds 8-10, 4-sided, truncated at both ends.

From an almost illegib’ label accompanying the only specimen we have 
seen, this seems to have been collected in Ceylon. 
640. (24) I. hirsuta (Linn.:) annual or biennial, erect, branched, every 
where except the leaves covered with soft spreading hairs: leaves pinnated ; 
leaflets opposite, 2-5-pairs, oblong-obovate, the terminal one the largest ; 
upper surface sparingly, the under densely clothed with adpressed silky ipe 
stipules long, setaceous : racemes dense, peduncled, elongated, usually longer 
than the leaves, many-flowered : flowers small: calyx deeply 5-cleft ; 568-7 
ments about as long as the corolla, subulate, hairy: legumes imbricate: 
flexed, straight, 6-8 times as long as broad, 4-angled, mucronate, V! on
