| Durand White Oak, Bluff Oak|
Quercus sinuata var. sinuata
Fagaceae (white oak group)
Durand White Oak grows on the rich, moist, neutral to acid clays and limestone flats and grasslands of the eastern third of Texas. It is a solitary tree that can grow to about 50 feet tall, and can sometimes be confused with a tall Bigelow Oak. The Durand Oak is a taller, more robust tree nurtured by thousands of years of richer soil and more rainfall, whereas the more xeric, smaller Bigelow Oak has evolved farther west, where rainfall sharply decreases and the water-holding capacity of the shallow limestone soils is less. These characters are by now fixed, so that seeds from each will develop true to the parent.
