Some Observations on the (ienus Kubus. 143 



ably fewer leaves, but a richer and somewhat unequal armature and white 

 fliiwers. The iuflurescence is also much smaller and fewer-flowered, and 

 somewhat glandulous, although the glandules are almost hidden by hairs. It can 

 be said to be related to its typical species, in about the same manner as the 

 weaker forms of R. eorylifolius * nemoralis are to R. corylifolius *\Vahl- 

 bergii. It seems, besides, to have a gieater likeness to the North German R. 

 villicaulis, than has the typieal species. 



Although this subspecies only occurs in several places within its small area 

 in Bohuslän, it shows some slight inclination to vary, but not to such a 

 degree, as to produce any more constant vatieties or subspecies. I have, for 

 example, at Häller, in the parish of Bro, seen a form the leaflets of which. 

 particulailv on the turiones, yes, even although in a less degree upon the 

 flowering shoots, were almost lobate and nearly doubly serrate. 



var. norvegicus; turionibus subglabrescentibus, angulatis & usque a basi 

 sulcatis, aculeis insequalibus, mediocribus, ad basin parum compressis, subulatis, 

 rectis vel parum curvatis, modice instructis; foliis 5-nato-digitatis, supra sub- 

 glabresceatibus, subtus pallide viridibus, tomento tenuissimo pilisque sparsis, 

 elongatie obsitis; foliolis minimis, brevissime petiolatis, sese tegentibus, insequa- 

 liter & subsimpliciter serratis; teiminali rotundato-ovato — obovato, acuto vel ob- 

 tuso; stipulis linearibus; petiolis aculeis minutis, curvatis instructis; ramis flori- 

 feris villosis, aculeis paucis, parvis, subfalcatis, in inflorescentia numerosioribus 

 & crebrioribus, instructis & glandulis subsessilibus munitis; foliis 8-nätis, foliolis 

 lateralibus sessilibus, late & oblique ovatis, terminali breviter petiolato, rhombeo 

 et breviter acuto vel subobtuso, foliolis omnibus inciso-duplicato-serratis; inflore- 

 scentia depauperata, efoliosa, simplici, racemosa, pedunculis inaxime abbreviatis; 

 sepalis extus canescentibus, haud appendiculatis, in fructu reflexis. 



Mr. S. Murbeck met with this form at Grimstad on the south coast of 

 Norway, where it grows in brushwood, between mountain slopes. 



I have considered this rather peculiar form only as a variety of R. confinis, 

 because the specimens are too incomplete tu make it possible to give a more 

 accurate description. For example, they were all of half-ripened fruit so that 

 t In' shape of the flowers could not be made out. The leaves upon the turiones 

 were al-o few and defective. This form gives the impression that under the 

 intluence of climatic sunoundings, and also, perhaps, of a sterile, stony soil, 

 it has been made still poorer in comparison with the typical R. * confinis, than 

 this is, in relation to R. insularis.
