solution would be that it was a hybrid between P. Aria and P. 
torminalis, and there is nothing in its distribution in England and on 
the Continent to forbid the supposition. 
P. scandica. In 1869, I first made acquaintance with P . 
scandica as a wild plant in Britain, Mr. A. Craig Christie having in 
that year sent to the Botanical Exchange Club numerous specimens 
collected in Glen Eis-na-vearach. Some of these are precisely 
similar to Scandinavian specimens in my possession, but the majority 
of them have the leaves narrower and more deeply lobed. Specimens 
from the Crook of Devon, where no doubt the tree has been planted, 
agree well with the Scandinavian ones, though even this has the 
leaves more deeply lobed than the Stockholm plants, though not more 
so than those from Upsal, P. scandica differs from P. latifolia in the 
texture of the leaves, which are less coriaceous, having much the 
same texture as those of the Mountain Ash. The leaves become 
glabrous much sooner, long before they are full sized, and show no 
trace of pubescence above in any specimens which I have seen in 
flower, either fresh or dried. But what gives the greatest difference 
of aspect is, that the general outline of the lobes of P. scandica is 
oval or roundish, not deltoid or triangular. The degree of serration 
of the lobes varies much, but the terminal tooth is usually larger and 
sharper than the others without, however, being so much so as to 
destroy the general curved outline of the lobe. The pubescence on 
the underside is greyer, and still less dense than in P. latifolia , and 
the tertiary veins are more apparent on the under side of the leaf. 
The lobes, too, diminish in size less rapidly from the base to the apex, 
and generally speaking are deeper than in P. latifolia. According to 
Tries they are sometimes so deep towards the base of the leaf, 
especially on the shoots of the year, that they become pinnatifid ; some 
of the Arran specimens have been divided nearly half way down. The 
flowers of the living plants which I have seen had a rather pleasant 
oddhr, resembling that of the mountain ash. The fruit of the Arran 
plant is about the size of that of P. rupxcola , and according to Mr. 
Duthie sweet-tasted. M. Grenier considers that Sorbus Mougeoti of 
Soyer and Godron is “a xerophilous form of scandica There is no 
doubt that it is nearer to scandica than to latifolia, and seems to replace 
P. scandica on the continent of Europe. It differs in having the 
leaves whiter beneath, and the fruit smaller. It seems to me to be 
between P. scandica and P. eu-aria. I have no foreign specimens of 
true P. scandica , except from Sweden and some received from the 
late Herr Buck, collected “ Prope Gelanum i.e., Dantzig. In 
Prof. Beichenbach’s collection there are four examples of P. scandica, 
all from Sweden, but none of P. Mougeoti.
