![]() Thank you for your time and consideration.Acer macrophyllum or Oregon Maple is a noteworthy native of the Northwest. We would, of course, gratefully acknowledge you and website as the original source in whatever manner you deem most appropriate. Given this, we were wondering it would be possible to receive your permission to adapt this image in our paper. Which corresponds extremely well to one of our simulated leaves. We were particularly intrigued by the following image of a Acer macrophyllum on this page: In preparing our manuscript, we came across your wonderful blog. Przemyslaw Prusinkiewicz (University of Calgary, The paper will be open access, and uses computational models grounded in biological studies of leaf form development to generate a diverse range of natural leaf forms. I am writing today with regards to a manuscript I am preparing for the scientific journal New Phytologist, in collaboration with Prof. I am a Post-Doctoral researcher at the Max Planck Institute for Plant Breeding Research in Cologne, Germany. Sorry again if this isn't the best way to contact you (I wasn't able to find your contact info anywhere else). I am contacting you again regarding obtaining permission to use the image of Acer macrophyllum in a paper for New Phytologist. Other Maple trees that I have posted about are the Vine Maple, the Red Maple, the Boxelder Maple, Sycamore Maple and the Montpellier Maple.įigurehead Industries (by RadiomanSun) Decemat 8:09 PM The winged seeds are wind dependent for dispersal and are often seen floating like "helicopters" in the fall winds." ![]() ![]() Clusters of yellow-green flowers appear in spring. The leaves are commonly six to ten inches long with five lobes. "This deciduous tree has the largest leaves of any native in our area. This sign (below) is located in the Multnomah falls visitor center reads. I did however find a few trees where the moss did not cover the whole trunk and was able to take this picture of what the bark looks like on a mature tree that was about 2 feet in diameter. On some of the trees in is practically imposible to see the bark of the tree. Their proximity to the falls and the constant water spray that is produced produces and moss and fern covering that is typical for this tree species. I have seen them all along the Columbia River Gorge as well as near the waterfalls of Silver Creek Falls State Park. The Big Leaf Maple tree is often found growing allong streams and near waterfalls. At any rate the leaves are quite large with some measuring 12 inches in diameter. It apprears to me that the leaves are larger and have sharper points on young trees while the leaves on more mature trees are a bit smaller and have more rounded tips. Some of the leaves were starting to turn a bright yellow color although the only decent shot was of one of the leaves I found lying on the ground. As you can see from the picture there are quite a few in each cluster. The image above is of a cluster of the Big Leaf Maple´s winged seeds (Samaras) that detach in pairs and are blown by the wind like little helicopter blades. The images in this post are from a stand of trees growing along the Multnomah Falls visitor trail that leads up to a bridge at the base of the main water fall (except for the leaf picture above which is from a young tree that I found on Mount Tabor Park in Portland). The Big Leaf Maple tree (Acer macrophyllum) is one of the few Maple tree species that grow native in the Northwestern United States.
