NOTES ON' ENGLISH RUBI. 101
ones are somewhat greyish and felted beneath ; the basal leaflets
are distiuctly stalked. The shape of the terminal leaflet is ovate
or cordate, gradually tapering into a h^ng point. Near Plymouth
(Egg Buckland ; Bickleigh, near Shaugh Bridge) Mr. Briggs
showed me a bramble he supposed to be my It. ojimits, and I tlnnk
his determination will prove to be correct, though the Devon jihint
seen by me is in all parts smaller than the German species. Prof.
Babington at one time thought it might be ll.jissus, but the characters
mentioned above will be sufficient for a clear distinction.

7. E. AFFiNis W. et N. — The figure of this bramble in the
* Eubi Germanic! ' is not good, and it may have misled many
students of the genus. I know the true plant from my visits to
"NVeihe's original stations, and from comparison of his own dried
specimens. The barren stems are tall, erect-arcuate, glabrous, and
remarkable for their very blunt angles and strong straight prickles.
The young leaves usually are white-felted beneath ; the terminal
leaflet is cordate-acuminate. The prickles at the base of the
panicle are remarkably long and slender, the flowers rather large,
the petals usually pale pink. The upper surface of the leaves in
the Dorset plant is somewhat more hairy than I am accustomed to
see it in German specimens. In every other respect the plants
from the different countries exactly agree. I saw U. ajfinis at
several spots near Bournemouth ;
Chine, S. Hants ; Canford
Chine and Gore Heath, Dorset.

8. R. iMBRicATUs Hort.—Near It. ajfinis, but in all parts smaller.
The barren stems are arcuate-prostrate and branching, very different
from the high arching ones in It. aj/inis. The panicle is narrower
than in that species. I saw It. inibricatus with Mr. Briggs at
several places near Plymouth.

9. R. KHAMNiFOLius W. et N. — It is very difficult to say what
is /('. rhamnifotiHH, although I know the typical plant quite well. In
every country, and often in every pruvnice, the rhdiiiiil/hliKsiype
has a somewhat modified appearance. In England, It. rhamnij'uiius
and /('. uinbiosits generally aiu thoiiglit to be very difi"erent plants.
A good deal of the dry branches, however, we see in the herbaria
cannot be arranged with any degree of certainty under one or the
other species. The most remarkable features common to all forms
of the aggregate species are a veiy much branched stem, strong
prickles, a small dentition of the leaves, an unusually lung foot-
