diadolphous, the filamonts not dilated. Style geniculate at the

Rootstock somewhat woody. Calyx-tube campanulate, very 

 short ; teeth subulate, about twice as long as the tube, the lowest 

 one a little shorter than the others. Wings little more than one- 

 third the length of the standard and keel. Pods reticulated on the 

 sides, with very prominent raised nerves, the lower margin with 

 acute tubercles or short spines towards the apex. 



On chalky banks, cliffs, and borders of fields. Not uncommon 

 in the South-east of England ; but it is impossible to say in what 

 stations it is native, and in what it is the remains of Saintfoin cul- 

 tivation. 



England. Perennial. Summer and Autumn. 



Eootstock dividing at the apex into numerous branches, and 

 terminating in stout tough stems, whicli arc curved at the base, 

 then ei-ect, somewhat flexuous, 1 to 2 feet high. Leaves 3 to 7 

 inches long ; leaflets :j- to f inch long, varying from oval to strap- 

 sbaped, generally truncate and apiculate at the apex, and slightly 

 nari'owed towards the base. Stipules broadly lanceolate-acuminate, 

 scarious, especially at the margins. Peduncles terminal, longer 

 than the leaves, terminating in compact spikelike racemes, 2 to 4 

 inches long. Pedicels scarcely so long as the calyx-tube, in the 

 axils of scarious lanceolate bracts, Avhich exceed them in length. 

 Calyx more or less thickly clothed with woolly hairs. Flowers ^ 

 inch long, rose-colour streaked with crimson, and suffused with that 

 colour at the apex of the keel ; wings so short that on a cursory 

 examination the flower might seem to consist only of the standard 

 and keel. Pods pubescent, i to f inch long, olive-colour, much 

 compressed, the upper margin nearly straight, the lower one curved 

 into more than a semicircle, somewhat truncate at the apex,
