Abstract

The American aspens, unlike most tree species, are normally able to initiate multi-stemmed clones (BARNES 1966), the larger ones having an appearance of groves. Throughout the range of the aspens the clonal habit is typical, although in dense stands the clonal structure often becomes obscure. While the clonal habit of aspens is basic in identifying natural clones, it is the amount and nature of intra- and interclonal variation which provides the ultimate source of information needed to delineate them. Such information was used by ZAHNER and CRAWFORD (1965) and BERTENSHAW (1965) in investigating clonal structure related to site quality.
