ovate-lanceolate, striate, but falling off as in the other species long before the 

 flower expands. Pedicels in distant pairs, much shorter than the calyx. 

 Calyx about 3^ lines long, divided almost to the base into 4 lanceolate acute 

 dry stiff lobes, overlapping each other on the edges and not striate, the upper 

 one (formed of 2 united) sliglitly notched. Petals scarcely exceeding tlie 

 calj^x or rather shorter. Pod scarcely exceeding the calyx, contracted be- 

 tween the seeds, into 3, 4 or rarely 5 articles, as broad as or broader titan 

 long, strongly marked with transverse wrinkles. — Hedysarum rvgosmi,W\\\ii.

The species is common in tropical Asia and Africa, where it varies much, sometimes low 

 and diffuse, with almost all the leaves obovate or broadly oblong, sometimes tall and almost 

 erect, with nearly all the leaves lanceolate or linear. It includes A. styracifolia, AV. and 

 Arn. Prod. 234, with short dense very hairy racemes and A, WaUichii^ W. and Arn. I.e., 

 with elongated nearly glabrous racemes. The Austriilian specimens have the habit of the 

 latter with the hairs nearly of the former. De Candolle'a specimen o^ A. stijracifoUa'n 

 nearer to A. WalHcMi^'W, and Arn. The original Hedysarum siyraclfoUum, Linn., is very 

 properly referred by W. and Arn. to a \^x^ difTcrent plant, Lesmodium retroflexim, DC, 

 which is surely a true Besntodium (sect. Nicohonia)^ not an Uraria. Ahjsicarjnts Hej/ne' 

 am(s, W. and Arn, 1. c, must probably be considered as another form of A. nigostis.

Calyx-lobes or teeth nearly equal or the 2 upper ones shortly united. Stan- 

 dard orbicular, obovate or oblong, nan'owed into a claw, or rarely obtuse 

 at the base ; wings free ; keel o!)tuse or rostrate. Upper stamen free or 

 farely united with the others ; anthers reniform. Ovary sessile or stipitate, 

 with a single ovule ; style filiform, with a small terminal stigma. Pod ovate 

 or orbicular, flat, reticulate, indebiscent.— Herbs undershrubs or shrubs. 

 Leaves pinnately 3-foIiolate or rarely 1-foliolate; leaflets entire, without sti- 

 pellse. Stipules free, usually small or very deciduous. Flowers purple pmk 

 or white, in axillary clusters or, in species"^ not Australian, in axillary racemes 

 or terminal panicles. 



The genus is spread over North America, temperate, especially eastern Asia, and the 

 )Uhtaius of E. India and the Archipelago. Of the two Australian species, one is Asiatic,

the other endemic.
