Zizia aptera is a flowering plant native to North America. Its common names include meadow zizia, golden alexanders, heart leaved golden alexanders, and prairie golden alexanders.[1]
The leaves are 2.5–10 centimetres (1–4 inches) long, ovate and indented at the base, with jagged edges; the upper leaves are divided into three segments.[2] Compound umbels of yellow flowers bloom atop the stems from May to July. The fruits are elliptical.[2]
Zizia aptera can be found throughout southern Canada and much of the continental United States, though it is absent in the Southwest, the southern Great Plains, and New England.[3] It inhabits wet areas.[2]
Zizia aptera is listed as endangered in Connecticut,[4] as rare in Indiana, as threatenedinMichigan, and as "historical" (extirpated) in Rhode Island.[1]
