Tliis species grows in the region of tbe southwest coast of Norway, at 

 Arendal, also on islands outside Hardcmger, where it is to be inet with aniongst 

 brushwood in open places.

Tbis species in many respects very nearly approachos R. pyramidalis. 

 So long as I had neither the opportunity of examining tbesc forms alive, 

 nor had a sufficieni numbre of dried specimens for examination, I also 

 considered that they belonged to tbe same species. They are separated, 

 however, by several verv important cbaracteristics, as appears from the descrip- 

 tion. Above all tlic inflorescence deviates. In R. pyramidalis, viz, tbe in- 

 florescence is only leafy ;it the base and beeomos sharply narrowed towards tbe 

 top, wliile the uppcr branches are shorter than the lower; moreover, the low.est 

 branchea of the inflorescence supporl small dusters, and the rachis, as well as
