Smith included P. fennica and P. semipinnata under his P. pinna- 
tifida. I have seen no Continental specimens, except from Scandi- 
navia, and doubt its occurrence in any place beyond the range of 
P. scandica ; there are no specimens of it in the collection of Sorbi 
sent by Prof. Reichenbach. 
Pyrus semipinnata, Roth. All the Scandinavian specimens 
which I have seen named Sorbus hybrida clearly belong to P. fen- 
nica, but those sent under the name of Sorlus hybrida from all other 
Continental localities differ from P. fennica in several particulars. The 
leaves are narrower. There is usually only one pair of pinnae, and 
very rarely indeed more than two. The first pair of pinnae are com- 
monly shorter and frequently broader than the first pair of lobes, if 
there be but one pair of pinnae. The pinnae are oval or ovate, usually 
entire in the lower half and rather bluntly serrated towards the 
apex. The lobed parts of the leaf are oblong -triangular, the lobes 
decreasing towards the apex of the leaf, obtuse and often quite 
rounded in outline, serrated towards the apex on the outer side, but 
generally nearly entire on the inner, the terminal tooth rarely larger 
than the others. The lateral veins on each side are 9 to 13, con- 
sequently more numerous than those of P. lvybrida . The upper 
side of the leaf when young is densely clothed with arachnoid hairs, 
but becomes nearly glabrous by the time the flowers expand. The 
under side of the leaf is clothed with rather loose grey felt ? 
resembling that of P. latifolia , more abundant and more dense 
than in P. fennica. By the time the plant is in fruit the leaves 
become nearly glabrous on the under side, with the lateral leaves 
standing out in strong relief. As a British plant this seems extremely 
rare, but it is probable that a specimen in Mr. Watson’s herbarium, 
received from Mr. Borrer belongs to it ; the label is as follows : “ Pyrus 
pinnatifida, from a moorish wood by the side of the road from Farn- 
ham to Farnborough Station, where Mr. Reeves showed me several 
plants forming part of the underwood, cut periodically. Among 
abundance of P. Aucuparia and P. aria.” A note in the u Phyto- 
logist,” 1854, p. 46, by Mr. Borrer, says, “ according to the ordnance 
map the station observed by Mr. Reeve is within the county of Hants. 
There are several plants among abundance of P. Aria and P. A ucuparia 
between which I cannot but suspect it is a hybrid.” I possess a 
specimen from the Rev. W. A. Leighton’s herbarium, with the label, 
“ Pyrus pinnatifida from Castel Dinasbran, planted in Mr. Doveston’s 
Mount Orchard, West Felton, Shropshire”; another from Mrs. 
Atkins, “ Storrington, Sussex, collected by Mrs. Dickson,” and others 
from Wastdale Head, Cumberland, planted, from the Rev. Augustin
