(d) Senticosa. This again is one of the rarer of our forms. Itisa 
weak straggling wood plant, which is either rare in Britain, or often passed over 
as not worth notice. In Herefordshire it has only been gathered in the Lord’s 
wood, Great Doward. 
(e) Dumalis. This variety is quite as abundant as Jutetiana; and might 
well be reckoned more abundant, were not the question rendered an idle one by 
the impossibility of fixing upon a limit at which one begins and the other ends. 
“Good” dumalis (with regular doubly serrate leaves and glandular petiole) has, 
occasionally, glands spreading to the midrib, and even the secondary veins 
of the under surface, and assumes the aspect of some of the Sub-rubiginose. This 
leads into 
(f) Biserrata; which can hardly be assigned any more independent 
position than that of exaggerated dumalis. As an extreme form, however, it occurs 
in several spots in Herefordshire, (first recorded by Mr. Purchas, from the Upper 
Cleave, Ross, upon specimens verified by Mr. Baker; then, by myself, from 
Allensmore, Orcop, and Saint Weonards) though in far greater rarity than 
ordinary dumalis. 
(9) Urbica. This Rose stands in a position of considerable independence 
in relation to the five above enumerated ; and is in its turn the chief of another 
group of three or four, Urbica is with us the third in frequency of the varieties 
of R. canina ; but it is, as at present defined, a name which covers two or three 
separate forms. What I take to be “typical” wrbica is a plant with light grey- 
green leaves, the leaflets flat and broad, with extremely regular, very open, and 
perfectly simple serration. These characters are often so marked as to give it a 
facies which stamps it to be (as Roses go) quite distinct from any of the foregoing. 
But other plants occur, possessing leaves which, except for their clothing 
of hair, might belong to lutetiana; and especially with the sharp, narrow, and 
unequal serration characteristic of that plant, yet which seem included under 
this name. We have also (from the Grwyne Valley) another plant exactly 
answering to the description of R. platyphylla, Rau., as quoted by Mr. Archer 
Briggs (Flora of Plymouth, p. 137); ‘‘a very luxuriant plant, with remarkably 
large glaucous leaves, slightly doubly serrated, the serratures terminating in a 
peculiarly stiff hard point ; stipules and bracts fringed with glands ; fruit nearly, 
or quite globose.” This surely deserves a separate letter. 
(h) Frondosa. This again is very near urbica; not, perhaps, differing 
more from wrbica than the various forms included under that name differ from 
each other. It is a small and neat leaved variety, the shape and serration of the 
leaves exactly that of typical urbica, with small round fruit. It appears to be 
fairly plentiful in Herefordshire ; it occurs at Welsh Newton, and in the parish of 
Saint Weonards; also in the parish of Clehonger; and at Backney, near Ross 
(W. H. Purchas). 
(h*) Obtusifolia, Too close, perhaps, to the last to merit a separate 
letter. But the fruit is generally larger, and less round; the leaves more hairy, 
though quite similar in shape and serration, This Rose is abundant and widely
