| Yaupon is a small evergreen holly tree native to the coastal plain of the southeastern US, especially common in maritime forests. It is also widely naturalized in the Piedmont, particularly in the Durham area, and usually occurs at the edges of woods. Dare Co., NC 11/11/06. |
| The small, elliptic leaves are thick, have crenate margins, and are glossy above. Dare Co., NC 11/11/06. |
| The young leaves contain caffeine and may be used to make a delicious tea, which is comparable to the yerba mate (Ilex paraguariensis) that Argentinians drink in copious amounts. The tea is a fine drink -- don't be put off by the scientific name, which refers to the effect of eating its fruits. Read a historical account of the tea use from John Lawson below. Dare Co., NC 11/11/06. |
