Littleleaf Form is a name that Michael Dirr attached to a plant that he saw at Hawksridge Nursery, Hickory, NC. It's a dilatatum taxon with a very refined habit, finely textured branching, and small dark green leaves being about one third to one half the size of the species. Unfortunately, being new to all who have seen it, no supporting information is available. Its size and texture make it quite unique. Could be quite interesting if it flowers and fruits like other dilatatum. More information will be posted as it becomes available. For the time being, as a collector you think: "Gotta have one of those".
