Crataegus laevigata

And about a tenth as many from Eastern Asia or Europe.

So especially if you're in the northeast of the U.S. or Canada, you might be wondering, what are we referring to in Western herbalism when we say Hawthorne? Now by most accounts, at least the printed text, we're talking about Crataegus monogyna, Crataegus lavigata, or Crataegus oxycantha.

Although this is one of the medicinals that's often referred to as just Crataegus species.

Often, or usually, ambiguity about botanical identification would make us uneasy, and rightly so, but not so much with hawthorn.

And in commerce, even if you were to buy a tree at a nursery or a specialty, these are often hybrids of a couple of these species.

So I mentioned Crotaegus monogyna and Crotaegus levigata.

These are European species, and the latter one is also sometimes called English hawthorn.

The monogyna refers to single-seeded, although I think most of these have singular seeds in the fruit.
