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 campanulate, the 4 upper teeth verv 

 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 2 in. long, with 5 to 8 transversely oblong seeds. 

 Hilum linear. 



Hongkong, Cham'pion, 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. calcaratus, chiefly in its narrow leaflets and glabrous surface. 



17. CAJANUS, Linn. 



Calyx campanulate, 4-toothed or lobed, the upper lobe 3-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, mark'ed with oblique indented lines between the 

 seeds. Strophiola of the seeds very small or none. — Eacemes axillary. Brac- 

 teoles none. 



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

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

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

 distinguished by the ovules always more than 2. 



1. C. indicus, Spreng.; W. and Am. Prod. Fl. Penins.'i. 256. An 

 erect undershrub of 2 or 3 feet, more or less covered with a short soft tomen- 

 tum. Leaflets 3, broadly lanceolate or oblong, acute, 1|- to 3 in. long. Stipules 

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

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

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

 curved point, more or less glandular and hairy. — C. bicolor, DC. ; Bot. Reg. 

 1845, t. 31. 



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 Arn. 



Elowers and other characters of Cajmius, except that the pod is either not 

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

 Herbs, usually twining. Leaflets 3, without stipellae. Racemes axillary, often 

 reduced to axillary fascicles. 



A genus of several species, aU from tropical Asia. 



1. D. conspersa, Benth. in PI. JimgJi. i. 241. A slender twining herb, 

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

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

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

 3-lobed. Plowers 2 together, or sometimes solitary in the axils of the leaves, 

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