Hippocastanaceae

Yellow buckeye differs from red buckeye both in having bright yellow flowers as opposed to red, and in being strictly limited to the Edwards Plateau, whereas red buckeye grows in east Texas on acid sands as well as in the Edwards Plateau. Where they meet, they hybridize and produce offspring with red-streaked yellow flowers.
