In our country tbis speeies is confi'ned within a very small area, on the 

 wost coast, in Bohuslän, between 58°, and 58°, 20' n. lat., whero it grows on 

 stony and sunny slopes, — for example — in many places in Ornat, Kalfön, 

 Grundsund, in Skaftön, also in the neighbourhood of Uddevalla. 



Outside the Scandinavian peninsula, the R. infestus is also very rare. 

 From Deninark, I have not seen tbis speeies which seems to be unknown to the 

 danisli rubologistB, although Focke (Die nordwestdeutsch. Rub. und ihre Verbr.) 

 states tlrat it grows in that country. In Germany, it grows almost exclusively 

 in the northwest part,, also in Thüringen (aecord. to Focke 1. c). It is also 

 to be fouml in several places in England. Even Focke (Syn. Rub. Genn. 

 pag. 274) is of the opinion that R. taeniarum, Lindeb. is to be referred to 

 R. infestus, and when, in the summor of lS83, I saw, for the first time, that 

 form alive, 1 beeame convinced of the correetness of this opinion. The Swcdish 

 form, however, does not correspond in all points with the German, at least, it 

 differe from the one, that I saw at Volmardingsen near Minden, in the under 

 aide of the leaves being generally oiore grey, also, the Upper flowering shoots 

 armed with stronger, and more numerous prickles. Speciraens, from Yorkshire 

 in England, given to me by Mr. J. (r. Baker, seem to agree more with the 

 Swcdish form. 



Like the former speeies, R. infestus, wheréver it grows in our country, 

 bolda itself almost unchanged and really do<'s not approximate to any of the 

 other Scandinavian speeies. Only in the most northern part of its area, near 

 Uddevalla, there grows a form, which in many respects differs from the typical 

 form, which also is to be found in the neighbourhood of this little town. 1 

 know il only from dried speeimens, that Mr. Scheutz had the kindness to
