E-oots^^ock short, not creeping, without subterranean stolons. 

 Stem erect or ascending, firm, much branched, generally (but not 

 always) with a number of spreading spines which are frequently 

 in pairs, slightly glandular-hairy, with a woolly strip on one side, 

 which changes sides at each node. Lower leaves trifoliate, the 

 upper ones generally unifoliate ; leaflets linear-oblong, denticulate. 

 Flowers solitary and axillary, chiefly on the bases of the spines, in 

 an elongated panicle or raceme towards the upper part of the 

 branches. Peduncles shorter than the calyx. Calyx with its 

 segments nearly equal, shorter than the mature pod. Corolla 

 much longer than the calyx. Pod erect, lenticular-ovoid, laterally 

 compressed. Seeds 1 to 3. 



On commons, barren pastures, and road-sides. Plentiful in 

 England, but apparently more rare in Scotland, whci-e it has not 

 been recorded northward of Haddingtonshire and Dumbartonshire ; 

 possibly it occurs in Porfarshii'e ; but there it may be the spinous 

 variety of the following species. 



England, Scotland, Ireland. Perennial. Summer and Autumn. 



Rootstock short, woody. Stems stiff, purplish, with ascending or 

 erect branches, 1 to 2 feet high. Spines ^ to 1 inch or more long, 

 spreading, leafy at the base, as it is only the apex of these stunted 

 branches which become barren. Leaves shortly stalked, with 

 large conspicuous oblong adnate stipules, which have a free ovate- 

 acuminate apex ; leaflets stalked, oblong or strap-shaped, \ to 

 ■g inch long, with very prominent lateral veins, each of which is 

 excurrent into one of the teeth. Calyx with 5 strap-shaped lan- 

 ceolate equal teeth longer than the tube. Flowers f inch long, 

 pale rose-colour, with deeper-coloured lines, darker on the apes of
