740 ARBORETUM AND FRUTICETUM. PART III. 



Spec. Char., S(C. Stem weak, roundish, bearing slender, very acute, and rather recurved, prickles ; 

 and, as well as the peduncles and petioles, villose, and hispid with glanded hairs. Leaflets 3, 

 rarely 5, ovate, doubly serrated, villose, thinnish. Flowers in loose panicles. Sepals lanceolate, 

 acuminate. A native of moist woods of Hungary. (Dec. Prod., ii. p. 562.) According to our 

 Hortus Britannicus, this was introduced into Britain in 1816 ; but, according to Dr. Lindley 

 (Synops. Brit. Flora, ed. 2 .), it is a native of Britain, and is " a strong glandular state of R. cae'sius, 

 approaching R. Ko'hleri," which he represents as one of that group of forms which he has asso- 

 ciated with R. corylifblius as the type.

Spec. Char., fyc. This, as compared with R. hi'rtus Waldst. 8; Kit., has its stem, petiole, and 

 peduncle very finely villous, and only very slightly hispid with glanded hairs. Leaves rather gla- 

 brous. (Dec. Prod., ii. p. 564.) This, according to our Hort. Brit., is a native of Germany, and was 

 introduced into Britain in 1823 ; it has pink flowers.

Spec. Char., fyc. Branches with scarcely any bristles. Stem leaves with 5 leaflets. Flowers in a 

 leafy straggling panicle. Spontaneous in Britain in hedges and dry ditches. In affinity it is nearly
