Group III.— VILLICAULES. Bab. 



Barren stems arching and rooting at the end, generally pilose, 

 often felted, and having sub-sessile glands rarely with a few gland- 

 tijjped sette ; prickles confined to the angles of the stem, nearly 

 uniform, or with a few smaller ones between the rows. 



Sub-Group I.— DISCOLORES. Bab. 



Stem with short copious pubescence ; prickles strong, uniform.

Stem arching, angular, furrowed, more or less thickly clothed 

 with short white scattered stellate pubescence ; prickles strong, 

 declining, from a large slightly compressed base. Leaves of the 

 barren stem quinate ; leaflets coriaceous, often deflexed at the 

 margins, glabrous and slightly shining above, white beneath, with 

 very compact short close felt, irregularly or doubly serrate ; ter- 

 minal leaflet oblong-obovate, cuspidate ; basal leaflets stalked, not 

 overlapping, sometimes joined to the intermediate ones. Flowers 

 in a long narrow panicle with the lateral branches short, spreading 

 corymbose, the lower ones often elongate, ascending, and racemose ; 

 rachis and pedicels densely white-felted, and with strong hooked 

 prickles. Calyx entirely white-felted. Petals pink. 



In hedges and thickets. Very common, and generally distributed 

 in England ; apparently rare in Scotland, except in the southern 

 counties. 



England, Scotland, Ireland. Shrub. Summer. 



A well-marked and handsome form readily distinguishable by 

 the leaflets being pure white underneath, and with the edges 

 generally deflexed, and by its large pink flowers. 



This is one of the commonest, if not the commonest, bramble in 

 England, but I do not remember seeing it in Scotland except in 

 Dumfriesshire and Kirkcudbriirht.
