摘要:
A new and distinct Ulmus parvifolia tree which is particularly distinguished in having an attractive, wide-spreading globe shape, being wider than it is tall, having lustrous and leathery dark green leaves, attractive puzzle-like, patchy and colorful quilt-like exfoliating bark patterns. The tree has a very dense and heavy canopy, and scaffold branch crotch angles of 60 to 70 degrees forming a strong tree which endures extremes of weather much better than most other members of the same and other shade tree species.
