Weird valley oak?
Monster old bur oak that has definitely lived a tough life. Almost appears to have a lighning strike scar along with some other damages from storms long since passed.
Within boundary of Wellington Botanic Gardens. Some plants will have been planted/cultivated
Escaped from a nearby yard.
Densely pubescent abaxial side
Volunteer under a Texas Live Oak. Leaves have slight lobes not present on Q. fusiformis. Other oak possible, but bo other species close by except Q. turbinella.
