“ mountain rocks, Llantliony Valley, Breconsliire, August 30, 
1876.— T. E. A. B. 
Jlosa tonientom, Sm. Denseln tjlandulur. Near Burntisland, 
Fife. September 2, 1876. In this form tlie glands spread to the 
upper surface of the leaves, which I have never seen the case witli 
the English plant. It is generally a low bush of compact growth, 
and barren shoots very scarce. — F. M. Webb. 
“ Bosa toiiientusa, Sm., var.” Bank of North Esk, Hawthornden, 
Edinburgh. August 8, 1876. This is a Eose (and a form of 
toiiientosa, I presume), that is new to me. Its peculiar prickles, 
thill (papery-like) concave leaves, and liabits are characteristic, 
and it is a fahly wide-spread form in Mid Lothian. — F. M. Webb. 
Looking at the prickles, I cannot consider this a form of tamenthsa, 
and would put it in the Caninte group. It is very near the “ Busa 
Watsoni," sent by Mr. Brotherston, but differs in having the 
peduncles aciculate. — T. E. A. B. 
/(. obtusifolia, Desv. Marston Green, Warwickshire (v.-c. 38.) 
August, 1876. Tliis form of Bosa canina appears to be widely 
spread through N. Warwickshire. I first found it near Solihull in 
two or three localities in 1873 ; afterwards, in company with Mr. 
Bromwich, I found it on Beausale Common ; and since that have 
found it in several other localities. It seems to retain its distinctive 
characters very truly. I have closely examined several bushes 
when growing together, and have found no tendency in any of 
them to iiass into other forms. — J. Bagnall. 
B. mhcrutata, Baker. Burntisland, Fife. August 14, 1876. 
This is the best mhcristata that we get hereabouts, there being none 
of the plant with the very compound- serrate leaves and glandular- 
backed sepals, to which form I prefer to attach Mr. Baker’s name. 
The jn-esent passes into the simple -serrate plant which I send as 
var. Beuteri. — F. M. AVebb. This is just what the Eev. AV. H. 
Purchas has sent from AVestside, Alstonfield, Staff’ordshu-e, as 
“ ‘ between sxihcristata and dumalis,’ J. G. Baker.” Mr. Brotherston 
has forwarded specimens of the plant with the very compound- 
serrate leaves and glandular-backed sepals, from Tweedside. — 
T. E. A. B. 
Jl. coriifolia, Fries. Minworth, Warwickshire (v.-c. 38.) Sep- 
tember 2, 1876. Two bushes of this plant occur at the above 
station. I also find it at Wishaw, and near Shustoke, all in 
Warwickshire. Mr. J. G. Baker has confirmed the AVishaw plant. 
— James Bagnall. 
II. Watsoni, Baker. Hedge, Kelso, Eoxburgh. July, 1876. 
Ditch-side near Eoxburgh Castle. September, 1876. — Andrew 
Brotherston. “ /.’.irGiso?//:, Baker.” Ape’sTor, Alstonfield, Stafford- 
shire. August 31, 1876. — W. H. Purchas. AVhile I believe that 
Mr. Brotherstoii’s specimens are rightly named, I incline to believe 
that many of those sent by myself as “ B. Watsoni" ought rather 
to be labelled B. co Hi folia. 1 took the name on Mr. Baker’s ipse 
dixit, but I see, on comparing specimens with his description, that 
they do not all answer to B. Watsoni, and that many of them agree 
very well with a specimen which he sent me at the time his
