with small stipitate glands, doubl; y dentate with glandular denticles. 
Stipules narrow, glandular. Auricles diverging. Peduncles soli- 
tary, axillary, glabrous or hispid. Calyx-tube globose, glabrous or 
hispid, with rough and reversed glandular sete at the base. Sepals 
entire, lanceolate, acuminate, glandular. Styles short, villous. 
Flowers white, claws yellowish. Fruit roundish, coriaceous, red, 
becoming black when ripe, crowned by persistent epals,”’ 
This differs from R. spinosissima in being more or less bi- 
serrate, the degree varying from very slight to — strong. Its 
glandular development on petioles and midribs s very decided, 
and the glands often reach the secondary nerves, but its peduncles 
are usually, not always, smooth. The sepals in all I have seen 
are ce te though the description ta they are glandular. 
n n I have seen specimens from Barnes Common 
Surrey, wae R. pimpinellifolia silat i in considerable quantity.

nea in Flor. Bad. Alsat. p. 358 (1826). 
“ f. matissima germinibus globosis pedunculisque glabris, peti- 
olis rancor subaculeolatis, caule ramisque inermibus.— Quite 
like spinosissima, but differs i in stem, branches, and peduncles un- 
armed, always smooth. Petioles thinly and minutely aculeolate. 
Leaflets 5 to 7, opposite, sessile, oval subobtuse, often oval lanceo- 
late, acute, coarsely serrate, light green, glabrous, small. Flowers 
terminal on branches, peduncles solitary. Corolla small, white.” 
0 judge from specimens placed to this species by Déséglise, 
not only are the stems quite or very nearly unarmed, but the 
e apex as in &. pimpinellifolia. Déséglise and pone consider 
Gmelin’s species to be synonymous with R. pimpine llifola 
y mermis DC. FI. Fr. iv. p. 488 (1815), fa no eaccation’ is given 
by De Candolle, so I have not adopted his name. He sede S, 
however, in the text pet it differs in its stems being cae | 
devoid of thorns, so it w ppear that both he and Gmelin h 
small-leay: t like io ingeeiay Linn. in their 2 Fe

I think they will best fit Gm elin’s species. A specimen by Don
