222 Mr. Anperson’s Description of a new British Rubus; 
gustata, apice obtusa cum acumine, inzqualiter serrata, raro incisa, scabro-ru- 
gosa, supra convexa, subnuda, saturate viridia; subtus cano-tomentosa, nervis- 
aculeatis. Panicula subracemosa multiflora, calyx fructus reflexus marcescens. 
Corolla rosea, raro alba. Fructus atro-violaceus, subdulcis, orbieulatus, acinis 
numerosis, confertis, seu connato-compressis, 
Common in. ditches and on way-sides about London, but 
seems to prevail less in the northern parts of the kingdom. It 
was no where to be found by me in Aberdeenshire or Perthshire, 
giving place as a companion to corylifolius, in those counties, to 
R. sub-erectus. This is by far the most robust of the three spe- 
cies, though not so uniformly upright as sub-erectus, throwing up 
long, vigorous, arched, tough branches, seldom trailing on the 
ground as in the preceding species ; armed with terrible prickles, 
proportionate in size to the branches, dilated at the base, firmly 
fixed on the shoot, and for the most part hooked ; particularly 
those of the minor branches and petioles. | 
Leaflets narrower and much less pubescent, with longer pe- 
tioles, clothed underneath with an imperceptible hoary down, 
that gives it a whitish appearance (though it varies in this par- 
ticular, for I have seen plants with leaves nearly equally green 
on both sides) Convex or rounded on the upper surface, and 
doubly or irregularly serrated, but more entire as well as more 
attenuated at the base than in the preceding plant. | 
The leaves of this species have a tendency to remain all winter 
on the branches, and seem more frequently quinate than ternate; 
those of corylifolius, on the contrary, more ternate than quinate, 
and drop off in the autumn, excepting in shady situations. 
This species and R. corylifolius are subject to vary widely : the 
above remarks must therefore be viewed on a general scale; the 
only constant mark of distinction yet discovered being in the 
situation of the prickles, as mentioned in describing the foregoing 
species, :
