Stems arching; prickles stout, hooked. Leaflets ovate-oval, 

 rather firm, not flat, green or slightly glaucous and glabrous above, 

 paler and downy on the veins beneath, deeply, sharply, and irregu- 

 larly but simply sen-ate, the serratm*es destitute of gland-tipped 

 sctte, but ciliated with woolly hairs ; petioles woolly, with a very 

 few gland-tipped setae and prickles. Stipules and bracts sub- 

 ghibrous or sparingly pubescent beneath, ciliated with gland-tipped 

 setoc and woolly hairs. Pedicels naked, as long as or shorter than 

 the bracts. Styles hairy. Fruit urceolate-ovoid, or subglobose, 

 ripening in October. Sepals leaf-pointed and copiously pinnate, 

 with a very few gland-tipped setae on the edges, falling before the 

 fruit is ripe.

 buted. 



" A closely-allied plant from Hawnby bank and hedges at
