Prickles robust and stron^^ly hooked. Leaflets flat, tlie ter- 

 iHiual one 15-18 lines long, broadly rounded or even cordate at 

 the base, the serration copiously compound, tlie upper surface 

 naked, the lower liairy on the ribs, and petiole never more than 

 fauitly, and sometimes very inconspicuously glandular on the main 

 veais and petiole, the aciculi strongly hooked. Stipules and 

 bracts naked, or very nearly so, on the back, densely gland- 

 cdiated. Flowers often numerous in a cluster ; the peduncle 

 weakly aciculate ; the calyx-tube ovate-urceolate, generally naked, 

 bepals copiously compound, naked on the back, reflexed or spread- 

 ing after the petals fall, disarticulated by tlie time that it changes 

 colour. Styles thinly hairy. 



This is a plant which has been more misunderstood than any 

 other British form, and which occupies just that intermediate 

 position between ordinary canina a.nd three or four of the others, 

 that varieties of the former are liable to be assigned to it by those 

 who have only book-descriptions to guide them. The true plant 

 IS clearly in its right place in the canina group, and is on the 

 whole nearer to tomentella than to any other variety. I have 

 seen it from Kent, Sussex, Surrey, Middlesex, Hertfordshire, 

 Shropshire, Worcestershire, and Yorkshire. B, inodora ft of the 

 'British Flora' I believe belougs to fomentosa. Hooker's plant 

 in the ' Flora Londincnsis ' is apparently tomentella.

Prickles more slender and less hooked thau in the last. 

 Leaflets obovate, full ^rcen, copiously doubly serrated, the base 

 cuneate, entire, the ujiper surface naked when mature, the lower 

 thinly hairy, plaijjly glandular on the midrib and main veins; 

 the petioles pubescent and finely glanduloso-setose, with a few 

 very slender, slightly hooked aciculi. Stipules and bracts thinly 

 hairy, and a little glandular on the back. Fh)wcrs never more 

 tlian 3-4 in a cluster. Peduncles very short, naked or weakly 

 aciculate. Fruit naked, oblong or turbinate, ripening early iu 

 ^September. Sepals not so conipouud as in the last, denstdy 

 gland-ciliated, thinlv <:landular on the back, ascendiiig after the
