ROSACE. 961 
of the late Mr. J. Irvine Boswell, Kingcausie, near Aberdeen, on 
a bank of peat mould brought from the neighbourhood in prepara- 
tion for a rhododendron bed; but careful search failed to detect it 
growing on the spot whence the mould was brought, and after a 
few years the plant died out in the garden, It is notan unlikely 
plant to occur; the most probable place for it is the district near the 
Sow of Atholl, where the Menziesia czerulea is found. 
RUBUS TOMENTOSUS. Borkhaus. 
A plant found at Horseton Hill, near Harrow, Middlesex, has 
been supposed to be a variety of this plant; Professor Babington, 
however, considers it is not that plant, but probably R. leu- 
costachys. 
ROSA CINNAMOMIA. 
E. B, No. 2388, 
Said to have been found in the wood at Aketon, near Pontefract 
Castle, andat Birk Hill, Galston, Ayrshire; 1 doubt escaped from 
cultivation. 
ROSA DICKSONI. Lindley. 
E. B. 8S. No. 2707. 
Said to have been found in Ireland by Mr. James Drummond, 
but probably not native. 
ROSA LUCIDA. E£hvrh. 
Mr. Borrer found this American plant near Keswick, where it 
had been mistaken for R. cinnamomia. 
ROSA POMIFERA. JHern. 
Found at Coates Heath, Staffordshire, by the Rev. R. C. 
Douglas; but probably escaped from a garden, as it is not unfre- 
quently cultivated. 
PYRUS SEMIPINNATA. Leoth. 
Pyrus pinnatifida, Zirh. ? Smith, E. B. No. 2331. 
The figure in English Botany appears to represent a plant 
which is commonly cultivated in gardens and ornamental planta- 
tions. I have received it from M. Huguenin, of Chambery, under 
the name of Sorbus hybrida. It seems to be quite distinct from 
the Scandinavian and Arran plant named Sorbus fennica by Fries, 
but has no claims to be considered as indigenous in Britain.
