Leaves oblong, oblong-rhomboidal, or ovate-oblong, glabrous 
above by the time the flowers expand, flocculent-felted and grey 
beneath, abrupt or wedge-shaped with an angle generally much 
ereater than a right angle at the base; margins pinnatifid from 
near the apex to the base, incisions deepest at the base, fre- 
quently so much so as completely to separate from 1 to 4 pairs of 
lobes next the base, so that they become the separate leaflets of a 
pinnate leaf; lobes much longer than broad, directed towards the 
apex of the leaf, or the free basal ones spreading, rather finely 
serrate ; veins 8 to 10 on each side. Calyx-segments applied to the 
petals in flowering, erect and inflexed in fruit. 
In rocky places. Very rare, and wild only in the northern part 
of the Isle of Arran. It occurs, however, in plantations in other 
parts of Scotland and in England, but I cannot help suspecting 
that at least in some of the localities given for it the plant 
supposed to be P. fennica is a hybrid betweeu P. eu-Aria and 
P. Aucuparia.

P. fennica is very closely allied to P. scandica, and indeed the 
leaves of some of the Arran plants resemble those of P. scandica 
more than they do the typical state of P. fennica. They have the 
same thin flocculent covering on the underside, but the incisions are 
deepest towards the base and not in the middle of the leaf. The 
flowers are considerably smaller, scarcely } inch across, and the 
calyx-segments do not spread widely when in flower, and in fruit 
the apices bend inwards. mm 
Smith’s P. pinnatifida (E. B. 231) appears to be, at least in part, 
drawn from the continental semipinnata of Roth.
