Oenothera serrulata A. A. Reznicek

Calylophus serrulatus of Michigan Flora.

Adventive in our area from the central United States. Collected several times in dry fields near the Sleeping Bear Dunes, Leelanau Co., first in 1948.

The short floral tube and short stigmatic lobes may lead to confusion with O. perennis, but the pubescence is not glandular as in that species, nor is the ovary 4-angled.

Locations

Leelanau County
