Discussion

Atriplex canescens var. laciniata, also a high polyploid, is supposed to have originated through hybridization of Atriplex canescens with a second chromosomal race of A. polycarpa. It is certainly similar to but has larger and more apparently laciniate bract wings than A. canescens var. macilenta, which arose similarly but purportedly from a different chromosomal race of the same species.
