U. lanceaefolia is very closely allied to U. parvifolia JACQ. from China and Japan. It differs from the latter by its narrow leaves with a shorter petiole, serrulate to serrulate-crenulate margin, and fewer lateral nerves, obovoid-globose buds, the campanulate perianth of the functionally 9 flower, and the reticulate venation of the fruit; see .


Very little is known about the usage of this species, but judging from the enormous size it can attain it must have been a useful timber in house-building, construction, etc., at least to the local inhabitants.
