unequal mostly straight intermixed with set®, leaflets small 
simply serrate, their disk eglandulose, calyx simple, fruit 
nearly globular. — a. leaves subglabrous. E. B. t. 187. R. 
pimpinollifolia L. — /3. pilosa ; “ very dwarf, leaves acute hairy 
on the under surface.” Lindl. 
Heaths, &c„ chiefly on sand and chalk ; most common towards 
the sea. — /3. Ireland, k- 5. 
4. R. rubella Sm. (red-fruited dwarf R.) ; stem and branches 
densely setigerous throughout, prickles few slender nearly 
straight, leaflets simply serrate naked, their disk eglandulose, 
fruit oblon" or urceolate. E. B. t. 2521, and fruit S. t. 2601, 
fig. 3. 
Rare. Sandy sea-coast of Northumberland, sparingly. Banks of 
the Dee about Abergeldy. k . 5. — Peduncles setose. This species 
is united, by Mr. Bentham, to the last species. 
5. R. Hibernica Sm. (Irish R.) ; shoots and ramuli sparingly 
setigerous, prickles scattered unequal, larger somewhat falcate, 
leaflets simply serrate hairy beneath, their disk eglandulose, 
calyx pinnate, fruit nearly globular. E. B. t. 2196. 
Counties of Derry and Down, particularly near Belfast. Near 
Lorton, Cumberland, k . “6 — 11.” Smith. — Peduncles naked. 
6. R. Wilsdni Borr. ( Wilson s R.) ; prickles crowded unequal 
straight intermixed with set®, leaflets simply serrate hairy, 
their disk eglandulose, calyx simple, fruit ovate-urceolate. 
E. B. S. t. 2723. 
On a declivity by the Menai, near Bangor, k . 6, 7. — Peduncles 
setose. Dr. Lindley thinks it a car. of R. mollis : but this and the 
two preceding seem to be but one species, only distinguishable from 
R. spinosissima by the scarlet not black fruit. As set® pass insensibly 
into slender prickles or aciculte, the species possessing the one may 
be expected to exhibit the other in some of its varieties ; and the 
greater or less number of either can form no specific distinction. 
7. R. involuta Sm. (prickly unexpanded R .) ; prickles crowded 
unequal straight intermixed with set®, leaflets doubly serrate 
hairy glandulose beneath, stem dwarfish. E. B. t. 2068, and 
fruit S. t. 2601, fig. 2. 
Hebrides, and Western Highlands of Scotland. Isle of Arran ; 
Islay ; Morven. Near Meggarnie in Glen Lyon, and elsewhere in 
the Highlands, k • 6- — Leaves often scarcely at all glandulose, 
except on the midrib. This species is united, by Mr. Bentham, but 
doubtfully, to R. spinosissima. 
8. R. Sabini Woods (Sabine's R .) ; shoots and ramuli seti- 
gerous, prickles scattered unequal straight or nearly so, leaflets 
doubly serrate hairy glandulose beneath. — n. calyx segments
