crenate leaves corresponding to f. intermedia Naruorst (Ofv. K. Sv. Vetensk. 
Akad. Forh., 1884, No. 1, p. 24 sub D. octopetala). 
Seeman (Fl. West Eskimaux Land; Voy. Herald, 1852, p. 29) says very correctly on 
this species: "the leaves are always smooth on the upper surface, never rugose, as those 
of D. octopetala; this character seems to be the best mark of distinction between the two 
species, all the others assigned to them are subject to variation”.
