NOTES ON DARTMOOR BORDER RUBI 315 
RHAMNIFOLI. 
Exclusive of the three very common species R. argenteus, 
R. dumnoniensis, and pulcherrimus, Abie group seems 
strongly represented on Dartmoor and its borders than in most 
English districts of like extent. 
‘R. embricatus Hort. 3. Frequent on the lower ground in the 
Teign Valley and in the neighbourhood of Plymouth, this plant 
comes scarce on higher levels; near a a Down, not far 
from the Rock ; Meavy Valley, near Yelverton, in one place. Nea 
Tavistock, Briggs. 4, S. Tawton, Sticklepath, pe Okehampton, 
frequent. 
R. nr igh Wh. & N. Certainly uncommon; if not, as I 
think, quite rare. 3. Lustleigh Cleave. Egg Buckland, Briggs, 
anbury. 
R. incurvatus Bab. Locally in fair quantity. Unquestionably 
a good form of this aggregate species as I understand it, though 
al exactly identical with the Welsh type. *3. Yennadon Down, 
near the reservoir ; Nara orough Down, between Yelverton and 
Horrabridge, ee . N. Tawton, Hiern; S. Tawton; 8. Zeal; 
Sticklepath; Belst 
R. Lindle elanus ie Widely but rather eed distributed. 
R. arg genteus Wh. & N. (BR. a eniclagr Geney. prius). So far 
as I ake been able to observe, this is the most generally distri- 
buted and most abundant bramble Sem the districts with 
bi ae this paper is specially concerned. Separate localities, of 
spots on Black Down, Yennadon Down, and elsewhere towards 
Princetown. 
R. rhamnifolius Wh. & N. The usual British form. Very 
unequally distributed; uncommon, except on comparatively low 
ground. 3. Moorland below Hey Tor; Teign Valley, common; 
este 
bourhood beyond Sataaat and Yennadon Down; Egg Bu 
neighbourhood, frequent. 4. S. Tawton; S. Zeal; Belstone and 
on. 
R. pulcherrimus Newm. As ‘Ape distributed as the last, 
and apparently ate as hardy. seems ocean quote
