comes next to R. canina in commonness, or at least disputes that place with 
R. arvensis. To both however it decidedly yields in abundance : i.e., though you 
will find R. tomentosa in every parish, possibly on every farm, you will find 30 
bushes of arvensis, and 100 of canina to one of tomentosa. When well grown, 
R. tomentosa, with its resinous-scented foliage and deep-tinted flowers, is a hand- 
some and conspicuous Rose ; but it exists also very frequently in cropped hedges 
without flowering, and is then very apt to be overlooked. We cannot at present 
lay claim to many of the named varieties. Hither they are less markedly separate 
from each other than those of canina; or the infrequency of individuals in this 
Rose affords fewer opportunities of studying them. They form one of the points 
in which the knowledge of Herefordshire Roses is most imperfect, and will most 
repay careful investigation. One or two, however, of its varieties, having been 
lately named for me by Mr. Baker, may now be included in our lists. 
Var. c. farinosa. A plant gathered by me at Aymestry last year is 
named thus, with a “‘?” by Mr. Baker. It was a peculiar plant, with barren 
shoots almost destitute of prickles ; leaves quite resembling mollissima ; and fruit 
naked. 
Var. d. scabriuscula. This is a well-marked variety, and willI believe 
prove not rare in Herefordshire. I have it from several widely separated 
localities (Aymestry ; Deerfold forest, Shucknell hill, Whitfield) ; and the plant 
from two of these was named “excellent scabriuscula,” by Mr. Baker. A plant 
gathered by myself and Mr. Purchas, near Mordiford, in 1873, most probably also 
belongs to this variety; though in point of glandular development of the leaf it 
comes nearer to var. e. sylvestris ; with which however it does not agree so well in 
other respects. 
5. Rosa rubiginosa, L. The ‘‘Sweet-brier” has a large range in 
Herefordshire, if we make its records a criterion (1, 2, 3, 4, 6, 8, 10, 13) ; and yet 
at the same time it is one of the least satisfactory of all our forms. Two doubts 
_ arise when reading these records; and they are doubts not to be set aside: one, 
whether the recorders knew it from R. micrantha; and the other, whether, 
supposing the species to be ‘‘ true,” it is a Native, or bird-sown from some neigh- 
bouring garden. I have gathered it at the ‘Common hill,” Fownhope ; at 
Shucknell hill ; at Aconbury; and at Breinton. In none of these stations can I 
affirm with certainty its native character. It is nearly always near houses ; and 
is not to be found in the thickets or remote hedges, where it should make an 
appearance if a true Native. It is most like a native plant at Breinton of all its 
Herefordshire stations ; for here several large bushes grow in a steep roughet over- 
hanging the river. It occurs also in a broad old hedge near Breinton Common, 
where of course it is likely enough to have been planted. 
6. Rosa micrantha, Sm. The genus Rosa affords one of the few instances 
in which the nose (in the human animal) is the surest guide he has to accurate 
knowledge. The Roses in the Sweet-brier Group, with the well-known and peculiar 
fragrance from which they derive their name, can always be told with accuracy 
from those of the tomentosa Group; and these, again, with their peculiar resinous 
scent, from those of the canina Group—by the help of the nose!; and this more
