Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net 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 species bear conspicuous red fruit on axillary pedicels. Since these species are dioecious (flowers rarely with rudiments of the opposite sex), fruit will be found only on female plants. Our native hollies are deciduous, but evergreen species of Ilex are familiar Christmas decoration; the traditional holiday colors reflect the red fruit and green leaves.
1. Leaves spiny-margined, evergreen.
1. Leaves soft-toothed or entire, deciduous.
2. Pedicels several times as long as the petals, mostly twice as long as the fruit, or longer; petals yellowish, linear, separate, the flowers opening in May (or June near Lake Superior); leaves entire (very rarely with a few sharp teeth).
2. Pedicels ca. twice as long as the petals, shorter than the fruit; petals white, broadly oblong-elliptic (less than twice as long as wide), connate at the base, the flowers opening in July (or June in southern Michigan); leaves with close, sharp teeth.
All species found in Ilex
