Q. macrocarpa x gambelii | Davis

Another of Cottam’s hybrids, this time a form of Q. macrocarpa x gambelii. In the Gambel oak section, we have already looked at the reverse of this hybrid, though created by nature, rather than artificially. The large, cartoonish nature of these leaves show the Bur Oak heritage clearly. Several hybrids with similar foliage, similar size, though variable growth habits, can be found in the Shields Grove.
