Leaves oblong, oblong-rliomboidal, or ovate-oblong, glabrous 

 above by the time the flowers expand, flocculent-felted and grey 

 beneath, abrupt or wedge-shaped Avith an angle generally mucii 

 greater than a right angle at the base ; margins pinnatitid 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 tow'ards 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 between P. eu-Aria and 

 P. Aucuparia. 



[England], Scotland. Shrub. Summer. 



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 l)ase and not in the middle of the leaf. The 

 flowers arc considerably smaller, scarcely i inch across, and the 

 calyx-segments do not spread widely when in flower, and in fruit 

 the apices bend inwards. 



Smith's P. pinnatilida (E. B. 231) appears to be, at least in part 

 drawn from the continental semipinnata of Roth.
