Flowering Branch, Side A
Glenburn Regional Park
A. ericoides is a member of the Multiflori complex. Associated with this complex are two characters whose states vary independently of each other. These states have been used to subdivide the complex into species and/or varieties. Different authors have done this in different manners. The following tables are a summary of the treatments by Flora of the Great Plains, Flora of North America, Flora of Alberta, and Budd's Flora. Note that Flora of North America has split the Aster genus into a number of different genera; the Multiflori complex is part of the Symphyotrichum genus in this scheme. This web site employs the nomenclature adopted by Budd's Flora.
