Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.


Our three species in this family are shrubs with a spicy-aromatic fragrance when bruised or crushed. The leaves and branchlets are ± pubescent in Comptonia and often so in Myrica. They also bear resinous orange dots (especially conspicuous in Myrica). Myricaceae, like Fabaceae, bear nitrogen-fixing nodules on the roots. Our species may serve as alternate hosts for the sweetfern rust fungus [Cronartium comptoniae Arthur], which is a cause of stem cankers in jack pine and red pine, especially the former.

1. Leaves pinnatifid their entire length, stipulate (the stipules eventually deciduous); staminate aments cylindrical, usually becoming somewhat lax and recurved; pistillate aments spherical, bur-like.


1. Leaves unlobed, entire except for a few teeth toward apex, estipulate; staminate and pistillate aments both short-cylindrical, rather cone-like, stiffly ascending.
