long. Stipules lanceolate, striate, produced below their insertion. Peduncles 

 longer than the petioles, with very few flowering nodes at the summit. Flowers 

 nearly sessile, 4 to 5 lines long. Calyx campamilate, the 4 upper teeth very 

 short and broad, the lower one lanceolate, but not so long as the tube. Stan- 

 dard orbicular. Keel with a long lateral spur on one side only. Pod slender, 

 nearly cylindrical, scarcely 3 in. long, with 5 to 8 transversely oblong seeds.

Hongkong, Champion, Hance, Harland. Originally described by Roxburgh, from speci- 

 mens raised from Chinese seeds, and not*known from elsewhere. It differs from the com- 

 mon Indian P. calcaraius, chiefly in its narrow leaflets and glabrous surface. 



17. C A JANUS, Linn. 



€alyx campanulate, 4-toothed or lobed, the upper lobe 2-toothed. Standard 

 orbicular, with inflexed auricles at the base, and 2 callosities inside, above the 

 claw. Wings and keel nearly of the same length. Upper stamen free from 

 the base. Ovary with several (more than 2) ovules. Style thickened above 

 the middle. Pod flattened, marked with oblique indented lines between the 

 seeds. Strophiola of the seeds very smaU or none.^Eacemes axillary. Brac- 

 teoles none. 



The genus, as thus limited, consists but of one species, hut with the two following, which 

 may be considered almost as sections of it, it forms a group resembling Ehynchosia and its 

 allies in habit, in the absence of bracteoles and stipellae, and other minor points, but readily 

 distinguished by the ovules always more than 2. 



1. C. indicus. Sprang.; W. and Jrn. Prod.Fl. Penins. i. 256. An 

 erect uudershrab of 3 or 3 feet, more or less covered with a short soft tomen- 

 tum. Leaflets 3, broadly lanceolate or oblong, acute, l-^ to 3 in. long. Stipules 

 lanceolate, deciduous. Peduncles axiUary, bearing at the summit a short ra- 

 ceme of flowers, either entirely yellow, or with the standard veined outside 

 with pui-ple. Pedicels about 6 lines long. Pod 2 or 3 in. long, with an in- 

 curved point, more or less glandular and hairy. — G. hicolor, DO. ; Bot. Beg.

Hongkong, Hance and others, but probably introduced. The species appears to be of 

 African origin, but is generally cultivated for its seed, the dhal of East Indians, in tropical 

 Asia, Africa, and some parts of America, and appears readily to establish itself in cultivated 

 and waste places. 



18. DUNBARIA, W. and Am. 



Flowers and other characters of Cajanus, except that the pod is either not 

 indented between the seeds, or slightly marked with transverse depressions. — 

 Herbs, usually twining. Leaflets 3, without stipeUae. Eacemes axillary, often 

 reduced to aJullary fascicles. 



A genus of several species, all from tropical Asia. 



1. D. conspersa, Benth. in PI. Jungl. i. 341. A slender twining herb, 

 hoaiV all over, with a minute tomentum, scarcely becoming glabrous when old, 

 and more or less sprinkled with resinous dots. Leaflets broadly rhomboidal, 

 seldom 1 in. long, entire, or the terminal one sinuate, or broadly and shortly 

 3 lobed Flowers 2 together, or sometimes solitary in the axils of the leaves, 

 on short pedicels. Calyx-lobes lanceolate-falcate, the upper and lower ones
