Corky flanges and colorful leaves

What books call the “corky flanges” on cedar elm trees, Ulmus crassifolia, are strange structures, typically wider than the branches they grow on. Here you see some particularly broad ones, along with a few unusually colorful cedar elm leaves, along the Boatright Memorial Trail in northwest Austin on December 15th. Talk about chaos, right?
