The article features two plant species of the North American genus Zizia which includes the golden Alexanders and the heart-leaved Alexanders, abundant across eastern North America and south from Florida to Texas, entering South Dakota.

It reports that David Mushet of the Northern Prairie Wildlife Research Center assigned a ranking of "C-value of eight", indicating that Zizia is a rare specie.
