The peduncles all arise from a primary involucre. In addition, each lateral peduncle bears a secondary involucre that is located at the base of of the peduncle. As a result, the single primary and multiple secondary involucres appear to form a single whorl. Occasionally one or more of the lateral peduncles will bear a tertiary peduncle which is located above the lower whorl and can be easily distinguished from it. When the key to the species in Flora of Alberta states peduncles naked, lacking secondary involucres; NOT [peduncles with secondary involucres], it is really referring to tertiary involucres. The key isn't totally accurate either, since, as stated above, tertiary peduncles will occasionally occur. The combined primary/secondary involucre usually contains twice as many leaves as peduncles (four peduncles and eight involucral leaves in the photo above).

The secondary involucres on the lateral peduncles of A. virginiana are located above the primary involucre and can be easily distinguished from it.
