We are sorry not to have images of every plant---we will fill in the holes as soon as they become available. Meanwhile, you can look at other images in our Vascular Plant Image Gallery
Northeast of the town of Navasota in Grimes County lies a small but fascinating sandstone outcrop. This particular hill represents the north easternmost extent of the Oakville formation, a ridge of limey sandstone which runs southwest all the way to Duvall county. For most of its length, the Oakville formation is covered with other layers of rock and soil. Where the sandstone breaks the surface, though, a rich and unusual flora has developed. Many plants found here are more typical of the Edwards Plateau region of Texas, hundreds of miles to the west. One plant, discovered in the 1990's, appears to grow here and almost nowhere else in the world.
The botanists of Texas A&M's Biology department invite you to
them as they explore this unique environment.
