Distinguishing between Betula pendula Roth. and Betula pubescens Ehrh. on the basis of wood anatomy.

It was concluded on the basis of the anatomical investigations of four mature trees that Roth can be distinguished from Ehrh. using the number of bars per scalariform perforation plate as an identification factor. If the average number of bars is more than 17.6, the sample is probably from , and if less, from The accuracy can be slightly improved by using the vessel frequency as another factor.Betula pendula B. pubescensB. pubescensB. pendula.
