L. Jr. 1971). The Wisconsin Natural Heritage Inventory Program currently (2023) lists this taxon in Wisconsin as a species of concern with a state rank of S2 (Imperiled in Wisconsin due to a restricted range, few populations or occurrences, steep declines, severe threats, or other factors.) This accession represents genetics (Richland and Iowa Counties, WI) from the extreme northern edge of the species native range. Specimens sampled in nature were multi-trunked specimens resulting from logging that occurred in the early 1900's. Specimens exhibiting attractive white bark. Specimen #222-2 had rather upright (e.g. 60 degree angled) branches. | 2141558 | Ames 36025 |

Photo(stapled to library copy). Plant named 'Howardi' by D. Howard. Dr. Santamour wrote D. Howard to say the name invalid by nomenclature rules D. Howard did not respond. In 1981, discovery was made by Dave Howard of what appears to be a new variety of Sycamore (Platanus occidentalis). This tree has spectacular yellow pigmentation in the new leaf growth. This bright lemon or daffodil yellow color in the leaves persists from leaf budding in the spring until late July. Architects, designers, planners and other users are invited to visit our nursery to see this new tree in the field and in a landscape planting. It is thought that this tree will have wide application for areas, lawn areas, etc. Planting of this tree in new areas as a "trail" planting will be encouraged by special pricing on prior approval by Burgaw Creek Nursery, Inc. owners. Our new variety of Sycamore is being expanded as fast as we can produce suitable bud and grafting wood. The patent has not been granted as of this date. We anticipate this being granted in coming months. Common Name Golden Sycamore. our nursery Form received: grafted plant. | 2145719 | NA 52894 |
