3. I. Anil, Linn. ; DC. Prod. ii. 225. A shrub or erect undershrub, 3 

 to 5 feet high, more or less hoary with appressed hairs. Leaflets in the more 

 luxuriant specimens often 8 or 9 pair, besides the terminal one, and full an 

 inch long, in drier situations often only 2 to 4 pair, and not above 6 lines 

 long, all opposite, from obovate to oblong, glabrous or nearly so on the upper 

 side, hoary with appressed hairs underneath. Flowers scarcely above 2 lines 

 long, in short dense almost sessile racemes, on very short recurved pedicels. 

 Calyx campanulate, with short broad teeth. Pods about -| in. long, usually 

 densely packed and much incurved, slightly tetragonous, with 6 to 10 seeds. 



On roadsides and in other waste places, Hance and others. The species is supposed to be 

 of American origin, but is now so generally cultivated for indigo in America, Africa, and 

 Asia, and spreads so readily as a weed, that it is impossible to fix its native country with any 

 certainty. The I. tinctoria, which is rather more generally cultivated in Asia, differs chiefly 

 in the looser racemes, with longer and more slender pods, always straight. 



4. I. venulosa, Champ, in Kew Journ. Lot. iv. 44. An erect glabrous 

 undershrub, 1 to 1^ feet high, the stems usually but little branched. Leaflets 

 opposite, 2 to 6 pair, besides the terminal one, ovate or orbicular, the terminal 

 one often 1 in. long, the others shorter, all very obtuse, or sometimes slightly 

 mucronate, green on both sides, the network of smaller veins very prominent, 

 quite glabrous, or with a few appressed hairs underneath. Racemes somewhat 

 shorter than the leaves ; the peduncle slender, bearing flowers only in the up- 

 per half. Pedicels 1| lines long. Flowers showy, of a reddish-lilac, about 7 

 lines long, the petals slightly pubescent. Calyx-teeth short. Pod straight, 

 glabrous, with several seeds. 



Victoria Peak, Champion, also Wright ; found also on Silver Island by Fortune, n. 43, but 

 not out of S. China. It is, however, nearly allied to the North Chinese /. macrostachya, 

 as well as to the following, /. decora, but may be distinguished from the former by its gla- 

 brous surface, from the latter by the smaller leaflets and flowers, from both by the prominent 

 veins' of the leaflets. 



5. I. decora, Lindl. in Journ. Hort. Soc. Lond. i. 68; and Lot. Reg. 1846, 

 t. 22. An erect shrub or undershrub, 1 to 2 or even 3 feet high, and nearly 

 glabrous. Leaflets opposite, 3 to 6 pair besides the terminal one, from oval 

 to oblong-elliptical, the largest from 1^- to 2 in. long, usually acute or scarcely 

 obtuse, glaucous, and slightly hairy underneath, the smaller veins scarcely 

 conspicuous. Racemes shorter than the leaves, like those of /. venulosa, but 

 the flowers themselves are larger and more showy. 



East Point, Hongkong, from Col. Eyre's drawings. ' I have not, however, seen Hongkong 

 specimens, but describe it from those gathered near Amoy by Fortune, and from garden spe- 

 cimens. It was also gathered in Japan by Wright. 



Tkibe IV. GJLLGEJE. 



Herbs, not twining, or shrubs, trees, or woody climbers. Leaves pinnate, 

 often stipellate. Racemes axillary or terminal. Stamens monadelphous or 

 diadelphous, the anthers obtuse. Ovary with 2 or more ovules. Pod open- 

 ing in 2 valves. 



4. TEPHKOSIA, Pers. 



Calyx 5 -toothed. Standard broad, as long as or longer than the obtuse 

 keel. Upper stamen free at the very base, but adhering to the sheath of the
