its extension on the continent of Europé shows, that it is a northern species 

 which originated under the influence of a colder climate (page 26). 



R. suberectus shows in this country but little inclination to vary, and 

 outside its boundaries holds itself very constant, although in the west of Europé, 

 as I have already in the introduction tried to show, it has given more or less 

 immediate origin to all the forms beloriging to Suberecti. In the western 

 part of the Scandinavian peninsula, there are found, however, intermediate 

 forms between this species and R. fissus, Lindl., which I eonsider as a 

 form of this species. R. fruticosus, sometimes, particularly when it grows 

 in woods, can show, in regard to the form of the leaflets, an åpproach to R. 

 suberectus, without one, therefore, having a right to talk of intermediate forms 

 hetween these species. Sometimes the turiones are almost unarmcd (var. mitis, 

 Arrhen. 1. c. page 21). 



What most characterise the R. suberectus, growing on the scandinavian 

 peninsula, are the erect turiones, slightly nodding at the top, the angles of 

 which are sparingly armed with small, slightly declining, bluish prickles, the 

 regularly simple, serrate leaves, the prettily cordate-ovate terminal leaflet on the 

 turiones, if, namely, the leaves are <|iiinate; and the intermediate leaflets, regu- 

 larly cordate-ovate, or ovate. The, usually, almost smooth and weakly armed 

 tlowcring-shoots, furnished with sessile glandules, bear temate leaves, whose 

 leaflets are ovate or oval. The filaments are longer than the styles, and the 

 receptacle smooth. 



Mr. Gabrielsson, student at the University of Upsala, has sent me a rather 

 remarkable bramble, which he, on the label, calls R. Säröensis. This form 

 is, without doubt, a variety of R. suberectus. I should, however, willingly 

 let it keep the name given it by Mr. Gabrielsson, if it did not seem to me, 

 for several reasons, unsuitable. I have, therefore, been obliged to give it 

 another name.

Mr. (tabeielsson has discovered this variety in a wood on the island of 

 Särö, in north Halland, on the west coast of Sweden. A form somewhat like 

 "' ha8 Deen given tu me by Mr. B. Lidfohss, collected at Förslöf, in the north- 

 wesl of Skåne. ~ It grows on open places, and therefore differs somewha! from 

 the typical variety, such as, by coarser prickles, and thicker, plicate leaves.
