I observed this tree on campus near Sorrin hall. Although the tree was beautiful, tall, and offered lovely shade, I was mostly curious about the identity because I noticed it had these long green seeds that I had seen before. During the Texas Spring, I find these long green seeds all over my car, dog, yard, and, somehow, my house. I was curious to determine the culprit of this annual mess, so I took a picture of the leaves and uploaded it to iNaturalist. I thought, because of the shape of the leaves that this tree was in the oak family. After I uploaded the picture of the leaves with the broad “oak” identification, someone commented and narrowed the id to Bur Oak. After some research, I found our that Bur Oaks do have the long stringy seeds that get all over my lawn in the months of March, April, and May.
