The mature plants of this species are well distinguished from those of U. glabra 
Hudson, but young vigorous plants are much more alike. The pale color of the 
branchlets in the autumn of their first year and in the second year, being somewhat 
brownish only on those parts which have been much exposed to the sun, seems to be 
the best character to distinguish U. laciniata from U. glabra. The perigones are 
often hairy besides being ciliated, as are the upper part of the pedicels. The fruits 
seem to be always quite glabrous, while, according to Trautvetter (1857), some 
Russian forms of U. glabra have a distinctly hairy disk, at least when young. The
