very rarely indeed more than two. The first pair of pinn^ 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. hylrida. 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 

 pinnatijida, from a moorish wood by the side of the road from Parn- 

 ham to Farnborough Station, where Mr. Reeves showed me several 

 plants forming part of the underwood, cut periodically, among 

 abundance of P. Aucuparia oiidi P. Aria.''^ A note in the " Phyto- 

 logist," 1854, p. 46, by Mr. Borrer, says, "according to the Ordnance 

 map the station observed by Mr. Eeeve is within the county of Hants 

 There are several plants among abundance of P. Aria and P. Aucuparia 

 between which I cannot but suspect it is a hybrid." I possess a 

 specimen from the Bev. W. A. Leighton's herbarium, with the label 

 *' Pyrus pinnatifida from Castle Dinas-bran, planted in Mr. Dovaston'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 Eev. Augustin 

 Ley. In the collection of Prof. Eeichenbach, so often mentioned, 

 there are four specimens of this — one from Montan de Bourget, pres 

 Chambery, Huguenin ; this is the normal form, in which the lowest 

 pair of pinnae only are separated ; another from Wellenger Berg bei 

 Amstadt Oswal, in which few of the leaves only have even the first 

 pair of pinnae separated ; and, thirdly, from Lingerberg in Thiiringia, 

 Sinowheit, which has some of the leaves with one pair of pinnse 

 separate, but the greater number only lobed. The fourth specimen is 

 from St. Maurice, Yallesia. This last specimen is more like P. 

 fennica than any of the others, having one or two pairs of separate 



pinnae, and the remainder of the leaf less prolonged than usual 



rhombic-triangular in one leaf, ovate-triangular in another ; neverthe- 

 less, from the blunt apices of the pinnae and lobes, with the terminal 

 tooth small, and the margins entire towards the base and on the 

 inner side, I consider it as P. semipinnata, with which it agrees in 

 the closer and finer felting of the under side of the leaf. In my own 

 collection I have normal specimens from *' Mont Bosson, pres Lau- 

 sanne, Leresche," and a very complete series in flower and fruit, from 

 M. Huguenin^ of Chambery. These specimens have some one, some
