Planta valde speciosa, cum nulla alia specie comparanda et cha- 
racteres H, umbellati (monticolae) et Pseudostenothecorum (Hololeiorum) ex- 
hibens, ergo potissimum H. dacico adjungenda est, sed foliis latis, invo- 
lueris sat dense floecosis pilosisque valde singularis. 
Nomen dedi in honorem el. D. Litwinow, meritissimi botanici, qui 
non solum floram Rossicam generaliter explorat, sed etiam difficile generi 
Hieraciorum animum advertit.
