B. francofurtana, Munch., 1770 (B. iurbinata, Aiton, 1811), 

 classed by some authors in the section Gallicce, is a hybrid of 

 unknown origin, but which is certainly distinct from B. gallica. 



Sect. VI. — Canine, Crejpin. 



(Sect. Cynorrhodon, Plur. auct.) 



Styles free, included ; stigmas forming a sessile head over the 

 orifice of the receptacle ; sepals reflexed after flowering, cadu- 

 cous, or erect on the ripe fruit, semi-persistent or persistent, 

 the outer ones pinnate with spreading appendages, very rarely 

 entire ; inflorescence generally many-flowered, with a more 

 or less dilated bract on the primary pedicels ; stipules adnate, the 

 upper ones more or less dilated ; leaves on the flowering branches 

 5- 7-foliolate, very rarely 9-foliolate ; stems erect ; prickles hooked 

 or curved, very rarely straight, alternate, rarely mixed with 

 glandular aciculi.
