 A plant of Peninsular India and Oeylon. The African plant bas larger, more pubes- 

 cent and more elliptical leaves than the Indian one, and more conspicuous stipules. 



2. I. linifolia, Eetz.; DC. Prod. ii. 222. Annual, 6-9 in, high, 

 copiously and diffusely branched, branches terete, erecto-patent, slender, 

 clothed with silvery-silky pubespence. Stipules minute, setaceous. 

 Leaves sessile, simple, linear, l|-2 in. long, |-| line broad, narrowed 

 gradually to both ends, acute, both sides, especially the lower one, 

 more or less densely clothed with silvery-silky pubescence. Flowers in 

 copious close sessile axillary racemes J-J in. long of 6-12 each. Calyx 

 campanulate, silvery, a line deep, the teeth linear, reaching three- 

 quarters of the way down, the two lowest much the longest. Corolla 

 reddish, three times as long as the calyx, the standard a line broad. 

 Pod round with an apiculus, a line thick, like the rest of tiie plant sil-

3. I. terminalis, Baker. Main stem woody, with dark shining 

 purplish-brown bark, the branches copious slender erecto-patent and 

 again .branched, the ultimate branchlets slender, terete, downy, not at 

 all silvery. Stipules linear-setaceous. Petiole ^— J in. long, spreading, 

 pilose like the branchlets. Leaflets 3-5, obovate-oblong, \ in. long, 

 1-1 J lines broad, apex rounded and mucronate, the lateral ones opposite 

 on short stalks, texture firm, both surfaces with a few adpressed strong 

 hairs. Flowers in moderately dense oblong terminal heads, which are 

 1-1 \ in. long. Bracts linear, equalling the flowers. Calyx \ in. deep, 

 not at all silvery, cut down nearly to the base, the teeth linear, \— f 

 line broad, distinctly ciliated. Corolla equalling the calyx. Pod ovoid, 

 mucronate, \ in. long, thinly silky, single-seeded.

£. I. congesta, Welw. mss. An undersbrub with an erect almost 

 woody stem sometimes 4 ft. high, with copious erecto-patent firm 

 terete finely downy branches. Stipules firm, rigid, linear. Petioles 

 spreading, J-f in. long. Leaflets 5-7, oblong or slightly obovate, 

 £-§ in. long, apex rounded and mucronate, the lateral ones distant, 

 opposite, nearly sessile, both sides, especially the under one, grey-green, 

 and finely downy. Flowers in dense rounded axillary clusters of 

 12—20, aggregated towards the end of the branches with the leaves 

 diminished to trifoliolate bracts. Pedicels equalling the calyx, which is 

 I in. deep, the teeth linear-setaceous, subequal, reaching down nearly 

 to the base. Corolla scarlet, equalling the calyx. Pod oblong, sub-
