240 WILD FLOWERS OF 



with surculosa, which seems chiefly characterized hy its numerous 

 cymes of flowers, I would unite with canina, separating the fol- 

 lowing. The R. bractescens of Woods is considered by HOOKER 

 and ARNOTT, " a mere variety" of canina. 



11. R. SARMENTACEA. Sharp-leaved Dog-rose. Leaves very 

 smooth, their leaflets sharply pointed and doubly serrated, pale 

 or glaucous beneath, their serratures as well as the petioles, 

 peduncles, and sepals fringed with glands. Fruit mostly naked, 

 but sometimes setose. On hilly ground, and the borders of 

 woods. 



Vars. of this rose occur with the fruit excessively setose, while 

 the foliage is very smooth and glaucous beneath. This deserves 

 to be named hispida, if it be, as is probable, the same with the 

 u hispida" mentioned by DON under canina, in his Gen. Syst.

 their leaflets doubly serrated. Cal. sparingly pinnate. Fruit

 with long taper points, the pinnse fringed with a few glands. 

 Styles united in a smooth furrowed column, very prominent after 

 flowering. Bushy places, but rare. 



The flowers of this rose are aggregated in numerous clusters, 

 but unless closely examined as it is going out of flower, it may 

 be easily passed over as a var. of canina. 



14. R. ARVENSIS. Trailing Field Rose. Branches very long 

 trailing, glaucous. Leaves simply serrated, glaucous beneath. 

 Flower stalks glandular, calyx sparingly pinnate, deciduous. 

 Styles united, hairless, very prominent, and persistent on the 

 smooth globular fruit. Very common except in mountainous 

 districts. 



This species trails excessively in woods, where its light green
