16. I. bongensis, Kots. et Peyr. PI. Tinn. 8, t. 4. Stems herbaceous, 

 slender, thinly adpressed- silky, the branches ascending. Stipules 

 linear, | in. long. Leaves simple, nearly sessile, obovate, an inch 

 long by more than half as broad, apex rounded and mucronate, the 

 upper surface green and glabrous, lower thinly adpressed grey-silky. 

 Flowers from the axils in 20-30-flowered racemes 1J-2 in. long on 

 firm slender peduncles which about equal them, longer in fruit. 

 Pedicels under a line long. Calyx campanulate, \ in. deep, grey- 

 silky, the teeth linear, reaching two-thirds of the way down. Corolla 

 purplish, twice as long as the calyx. Pod J-j in. long, 1 line broad, 

 linear, straight, silky, 6-7-seeded.

Habit of I. trita and subulata, but simple-leaved. 



17. I. xmmmularia, Welw. mss. Stems suffruticose, 1^-2 ft. long, 

 prostrate, with numerous spreading finely grey-downy branches. Sti- 

 pules linear-setaceous, persistent, 3-4 lines. Leaves simple, rotundate- 

 obovate, with a short distinct petiole, reaching 9-12 lines long, 7-8 

 lines broad, subcoriaceous, blunt with a distinct mucro, both sides 

 green, scabrous with minute adpressed grey hairs. Flowers 4—8 in 

 copious moderately dense axillary racemes on slender downy peduncles 

 which about equal them. Calyx 1 line, densely grey-hispid, teeth 

 setaceous, reaching down nearly to the base. Corolla bright red, J in.

 high, branched copiously and diffusely, the branches firm, terete, 

 densely clothed with fine white spreading silky pubescence. Stipules 

 linear-setaceous, silky, spreading. Leaves nearly sessile, with two 

 unequal leaflets, the terminal one considerably the largest, suborbicular 

 or obovate-cuneate, J-l in. long, \ in. broad, on a petiolule 1^-2 lines 

 long, the lateral one smaller, sessile, spreading, apex rounded and 

 mucronate, texture thick, both sides more or less densely clothed with 

 spreading silvery pubescence like that of the stem. Flowers in copious 

 dense oblong-conical racemes 1-1 J in. long, of 20-40 flowers each, 

 nearly sessile, or on peduncles \ in. long from the axils of the leaves. 

 Bracts linear, exceeding the pedicels. Calyx campanulate, very silky, 

 \ in. deep, the teeth setaceous, reaching down nearly to the base, the 

 lowest the longest. Corolla rose-pink, twice as long as the calyx. Pod 

 sessile, linear, |-^ in. long, very silky, deflexed, 2-3-seeded, with a 

 barren upcurved point, nearly half as long as the fertile portion. — Guill.
