Iris lacustris Nutt. | |
Iris lacustris (Dwarf lake iris), is a beardless rhizomatous iris (genus Iris, subgenus Limniris) native to the Great Lakes region of eastern North America.[1]
Distribution
I. lacustris is found on northern shores and smaller islands of Lake Michigan and Lake Huron, on the Door Peninsula of Wisconsin, and on the Bruce Peninsula and Manitoulin Island in Ontario, Canada.
I. lacustris grows on alvar limestone barrens.[2] It is a close relative to Iris cristata (Dwarf crested iris), the only other crested iris native to North America. However, unlike it, I. lacustris is found only in small areas of the Great Lakes region that have been glacier-free for only 11,000 years.[3]
Status
In 1998 I. lacustris was designated the state wildflower of Michigan,[4] where the vast majority of populations exist.[5]
It is designated a vulnerable threatened species by federal, state and provincial laws throughout its distribution range.[6]
