Even the Plants Have Teeth

Some days it seems like the Sindecuse Museum staff see teeth everywhere we go and this spring is no exception. Today it’s plants with teeth. We’re lucky to work on in a research campus here in Ann Arbor, so we checked in with the experts at Matthaei Botanical Gardens & Nichols Arboretum to find out more. Here’s what we learned:

When the Latin dentata (same root word as dentistry) appears in a plant name it signifies a tooth-shaped appearance. This can mean a tooth-like appearance to the edges of leaves or any other part of the plant, says curator Dr. David Michener.

Chad Machinski, who is caretaker of the Matthaei Botanical Gardens & Nichols Arboretum, shared these toothily-named plants that are native to Michigan.

Castanea dentata, American Chestnut

Populus grandidentata, Big-Tooth Aspen

Sibbaldioposis tridentata, Three-toothed Cinquefoil

Viburnum dentatum, Arrowwood

”In addition,” Machinski wrote, "there are a few that don't have "dentata" in their scientific name anymore, but do have "tooth" in their common name. The following had been in the genus, Dentaria but are now in the genus, Cardamine: “

Cut-leaved Toothwort

Two-leaved Toothwort

Large Toothwort

Look out for these, and other plants with teeth on your spring tours in U-M’s gardens or wherever you like to enjoy nature and take in the change of seasons. And be sure to check out their website for maps, many more images, and to learn all about their projects: https://mbgna.umich.edu/
