specimens sent were two from different localities, which the Professor 
identifies as Rosa drier ascens, Dumort. This is a variety of R. tomen- 
tosa , Sm., and has simply serrate leaves. This form is not given in 
the London Catalogue of British Plants, and is a new record, at least 
for Perthshire. A considerable number of specimens are identified, 
some as R. sub-canina , Christ., and the rest as R. sub-collina , Christ. 
But of these the Professor remarks—“ The feeble and transitory 
characters of the glabrous and pubescent forms of this intermediate 
group render the determination of herbarium specimens often pro¬ 
blematical. Accordingly it is with many reserves that I class these 
specimens. It is your business to clear up on the living bush any 
doubts regarding these forms.” 
In conclusion, I may mention that I discovered in Glenfarg a 
new station for that very scarce Rose, R. involuta , Sm. This makes 
the eighth locality known to me in Perthshire for this interesting hybrid. 
The others are Callerfountain Hill, Old Road near Kinfauns, Waulk- 
mill, Auchterarder, Gleneagles, Dunkeld, and the Roadside near 
Cluny Loch. At all the stations there is only a single bush or two, 
except at Waulkmill, where there is quite a little colony. Professor 
Crepin thinks that all the Perthshire forms are hybrids of R. pimpi- 
nellifolia , L., x R. fomentosa, Sm.
