longitudinal line of fine hairs on the back of the standard. Pod gla- 

 brate. 



Known only from Assam, elsewhere! introduced into the Hawaiian Islands. 



2. C. SERiCEA Betz. {Enum. No. 96.) Stem erect, 3° -8° high, 

 obtuse-angled, glabrous ; leaves oblanceolate, blunt, mucronulate, 

 tapering at base into a short petiole, glabrous above, subsericeous 

 pubescent beneath, pellucid-dotted, 2' -5' long, h' -^h' wide. Stipules 

 sessile, semisagittate, somewhat reflexed. Eacemes terminal, elonga- 

 ted, many-flowered, each pedicel from the axil of a large ovate acumi- 

 nate bract. Calyx bilabiate, ^' long, about half the length of the 

 yellow corolla, the superior lobes ovate, inferior ovate-lanceolate. Pod 

 oblong, much inflated, shortly and broadly stipitate, glabrous. 



Not uncommonly planted around native houses as a hedge; doubtless introduced, 

 Native of the East Indies, and naturalized in the West Indies. 



3. C. LONGiROSTEATA Hook. <fi Am. (Enum. No. 97.) Suflruticose, 

 2° -3° high, branched, minutely pubescent with fine hairs. Leaves 

 long-petioled ; leaflets 3, obovate or oblong, obtuse or slightly retuse, 

 mucronulate, tapering to a somewhat cuneate base, terminal one 1' or 

 more long, the lateral ones smaller. Stipules, and also bracts, very 

 small, scarce 1" long, subulate, pubescent, deciduous. Eacemes ter- 

 minal, becoming lateral by the evolution of the stem, many-flowered. 

 Plowers large, yellow. Pedicels 2" -3" long, recurved in fruit. Keel 

 with a long straight beak, 7" long, exceeding the other petals. Calyx 

 5-lobed, the two upper lobes ovate-lanceolate, the others linear-lance- 

 olate, all slightly pubescent. Pod oblong, 6" -9" long, on a stipe 

 which is shorter than the calyx, minutely pubescent. Ovules about 

 10, seeds 4-6. 



In waste places, road-sides, etc., near Honolulu. Doubtless introduced. Native of 

 the region about Acapulco, Mexico. 



Tbibe II. INDIGOFERE^. 

 A small tribe, almost limited to the genus Indigofera, distinguished chiefly by the an- 

 thers, tipped with a gland or point, from Galegex, with which they would be united, but 

 that the leaflets are in a few species digitate, as in Genisteas. 



2. IM"DIGOPERA Linn. 



Calyx small, broadly and obliquely campanulate, with 5 teeth or 

 lobes, the lowest the longest. Standard ovate or orbicular. Keel 

 erect, with long claws, and a small protuberance or spur on each side 

 above the claw. Stamens diadelphous, the sheath slender, and usually 

 persistent after the fall of the petals. Anthers tipped with a small 

 gland or point. Ovary sessile or nearly so, with several ovules. Pod 

 usually slender, cylindrical or 4-angled, with transverse cellular par- 

 titions between the seeds, rarely flattened, or when reduced to a single
