 182 REPORT OF THE BOTANICAL KXCIIANGE CLUB.

Rosa micrantha, Sm., var. Br'iygsii, Baker. " Collected from the plant so named by Mr. Baker in his recent ' Monograph of the British Roses.' Specimens from Fancy Wood, of another naked-peduncled form of R. mi- crantha, with very small fruit, are sent, that they may be compared with the other." — T. E. Archer Briggs.

R. verticillacantJia, Merat. "From Harestone, Brixton, showing a peculiar armature on the branches. The form from Warleigh is re- markable for having prickly fruit." — T. R. Archer Bkiggs.

R. arveii.sis, Linn. var. bibracteata. Bast. "This occurs in many spots near Plymouth." — T. R. Archer Briggs.

R. nrvensis, Huds. var. Chesterton Wood, Warwick; H. Bromwicii. "A very curious form, bearing the same relation to the type that my var. gallicoldfS, from the same station, bears to typical R. stylosu. It is not named in Continental books, so far as I know." — J. G. Baker.

Pyrns communis, Linn. " Hedge, l)etween Thornbury and Common Wood, Devon." — T. R. Archer Briggs. A well-marked form which I cannot identify with any of those described by French writers. The branches are apparently not spinous, the leaves small, about an inch long, oval, acuminate, rounded at the base, finely crenate-serrate, very slightly puljcscent beneath and on the margins when young, glabrous when mature. Flowers small, about f inch across, in a cyme, of which the rachis is often &o elongated that it becomes somewhat racemose. Calyx densely and finely woolly. Styles a little shorter than the stamens. Fruit f to |- inch long, roundish-turbinate, abruptly narrowed into the long pedicel. I propose the name of Briggsii for this form if it be really destitute of a name.

P. scandica, Bab., var. fennica. " Glen Eisna-Vearrach, Arran ; and P. scandica, var. pinnatifida. Side of rocky stream. Glen Catocal, Arran." — J. F. Duthie. Mr. Duthie has settled the point of there being two forms of P. scandica in Arran, one of which has the leaves with none of the segments separated, the other, with some of the h aves pinnate at least towards the base. All the specimens which he found in one glen belonged to the fornifr, and all those in an adjacent glen to the other. He had an opportunity of tasting the fruit of both, and found it to be sweet. Fries thinks this the best mode of discriminating the pinnatifid variety of Sorbus scandica from Sorbus fennica, Fries, of which the fruit is acid. The Arran plant appears to be a subspecies different from that of the .south-west of England, which has been sent by Mr. T. R. Archer Briggs and others.

Epilobium. any nstifolium, Linn. var. bruclnjcurpnm. " Cocken Woods, Durham." — H. E. Fox, Unfortunately there is no note to the specimen to say whether or not it has any claim to be considered native in this station.

Ribes alpinum, L. " The specimens which I send from Herefordshire are from a bush growing in a locality where it presents all the appearance of being planted or naturalized. I send also specimens from Derbyshire. I have found it in three or four different localities in the Peak of Derby- shire, growing very freely, and evidently fully naturalized, if not native." — AuGusTiN Ley.

Saxifraga umbrosa. "The locality in Ashwood Dale, near Buxton, is at least a quarter of a mile from any house. The plant here is very luxuriant, and seems as truly wild as in any part of England." — AuGusTiN Ley.
