Many species have gone extinct.
There were even some species that reached tree-like proportions in the (now
extinct) allied genus Calamites!!!

Don't worry. They went extinct hundreds of millions of years ago.
Long before you were even born!!!

There are only about 30 species of Equisetum that survive today.

It just seems awful when somebody wants to eradicate a living fossil.

The few remaining Equisetum species have ancestors dating back to long
before the age of dinosaurs.

HELP!
Please can any one tell me how to get rid of the weed Mares Tail

Equisetum is in no danger of going extinct in Alaska. It's all over the
place up here and probably all across the circumpolar areas of the
planet. It's flourishing in my garden right now, but it's easy to pull
the mare's tail phase up when I weed.

Have varieties gone extinct?
