Oak Info

1. There is only one Genus of oak, Quercus, but many species. Taylor county and surrounding area has about a dozen of the more than 50 species native to Texas.
2. Leaves come in a large range of sizes and shapes.= Even on a single tree, the leaves vary and can look like another species. To make identification even more difficult, many species cross-breed easily.
3. The word "shinnery" may be derived fromchêne (French for oak), and not from the size of the plant.
4. The male and female flower parts are produced in separate flowers but on the same tree. Male flowers grow on long clusters called catkins. Female flowers are tiny at the ends of stems.
5. The fruit of oaks are called acorns. They form inside cups with a hard outer shell and a nut inside.
