Oakwillows were trees found in the Deepwoods. Their appearance was never described, which makes it difficult to say if they are more similar to oaks, like the redoak, or to willows, like the lake-willow or the sleeping-willow. Weelum made a sleeping nest for him and his friends during their journey to Hive using oakwillow fronds interlaced with briargrass and glade fern[1].
