Osage Orange Maclura pomifera (Rafinesque) SchneiderNon-native  Synonyms: Toxylon pomiferum.

Relationships:

The large, heavy, fleshy fruits of Osage Orange have apparently had no effective dispersal agent since the extinction of ice age megafauna such as giant ground sloths, mastodons, and mammoths. The loss of these animals is thought to have restricted the plant's post-ice age natural range to Texas, Oklahoma, and adjacent areas of the southern plains, where it was driven by the last glaciers. Since then, humans have widely planted Osage Orange for hedges, fencerows, and windbreaks, and it has escaped from cultivation in Maryland and many other states. Squirrels and quail eat the seeds to a minor extent (J. Hill/MNPS).

There are 77 records in the project database.
