I am following Checklist of the Vascular Plants of Saskatchewan and Flora of Alberta in defining A. neglecta broadly enough to include A. howellii, A. neodioica, and A. russellii.  However, these authors do consider A. corymbosa as a separate species, and I am not completely sure that this specimen is not A. corymbosaA. corymbosa has a dark brown or black spot below the whitish terminal portion of each involucral bract.  Some of the bracts of this specimen have a dark reddish coloration on the margins of the basal green portion.  In the future, I hope to photograph A. corymbosa (which is rare in Saskatchewan) and resolve the ambiguity.
