also often glandular ; sepals suberect, subpersistent ; fruit roundly 



oval aciculate. 



Rare, but widely scattered in Britain. West Kent ! Surrey ! 



West Lanes ! Yorks ! Dumfries ! Mid Perth ! 



6. R. suberecta. R. villosa b. suberecta Woods in Trans. Linn. 

 Soc. xii. 192 (1818); ex descript. Thorns straight, sometimes 

 robust ± falcate; leaflets oval- elliptic, ± hairy on both sides; 

 subfoliar glands few or many ; petioles very glandular, with many 

 unequal, falcate acicles and pricklets ; clusters of 1-5 flowers ; peduncles 



moderate, these and the ovoid calyx-tube densely and longly glan- 

 dular-aciculate; fruit globose ; sepals considerably pinnate, appen- 

 dicnlate, densely glandular-aciculate, suberect and subpersistent. 

 Petals rose; sometimes "white with purplish spot " (Marshall). 

 Young stems, petioles, thorns, stipules, and bracts vinous red. 



The above description, taken from recent British specimens, 

 agrees so well with Woods' original description which is here sub- 

 joined, as to leave no doubt as to the identity of the plants : — 



" Fruit globose, that and the petiole furnished with strong setae; 

 flowers deep red. Stem stiff and upright; leaflets 7 sometimes 9, 

 elliptic concave ; stems, petioles, young prickles, and mid-rib of a 

 vinous red. The general appearance of this variety is such as to 

 make me wish to consider it a distinct species." 



R. suberecta Woods varies greatly in the shape and direction of 

 the thorus and in the clothing of the leaflets ; the flowers also are 

 sometimes white. It is, notwithstanding, an easily recognized 

 species ; the vinous colour of its younger parts seems jnever to be 

 wholly absent, even in the albino variety. Endemic? 



Widely spread in the North of England and Scotland, and 



occurring in Ireland. Carnarvon! Derby! West Lanes! N. E.

Fries's original description of his plant runs as follows : — 

 "Foliis utrinque glaberrimis subtus glanduloso-punctatis. In 

 maritimis Blekingi®. Hanc primo obtutu R. caninum crederes, sed 

 aculei recti teretes, foliorum serraturas et glandule, petala denticu- 

 lata, fructus molles precoces hispidi omnino ut in vulgari."
