Abstract

Anatomical comparison of 3 North American species with commercial name of redcedar was executed to provide taxonomic information for prevention of confusion and establishment of sound business transaction in the wood market. Eastern redcedar (Juniperus virginiana) and southern redcedar (Juniperus silicicola) could not be separated on the basis of microstructure and ultrastructure of wood. Western redcedar (Thuja plicata), however, appeared to be obviously separated from eastern and southern redcedar in a number of microscopic and ultramicroscopic features. Useful features for separating these two groups were intercellular spaces in transverse surface, latewood width, radial intertracheid pitting, warty layer and pits with torus extensions in tracheids, ray composition, nodular end walls in ray parenchyma cells, and cross-field pitting.
