Amelanchier utahensis Koehne. The styles appear to be perhaps 3-4 (and usually are 5 for A. alnfifolia but do appear to be distinct or separate at least towards the top rather than united to the base but it is difficult to see here; leaves appear glabrous yet normally are pubescent throughout the season for this species. Leaves are serrate or serrate-crenulate.May 22, 2010, base of Parley's Canyon, approx. 5100 ft. elev.

Flowers of Amelanchier utahensis, a native woody shrub to small tree that is locally uncommon but widely distributed in the state. Ongoing research will better determine the relationship of A. utahensis and the closely related A. alnifolia. A. utahensis has smaller leaves and is more pubescent and has styles that are normally distinct to the base. The distinct styles can be seen here. While A. alnifolia usually has five but sometimes four united styles, A. utahensis usually has two or three that are distinct to the base, although western Great Basin plants are reported to have four (or five!) styles, compared to two or three from other areas. It turns out that the distribution of A. utahensis plants containing four or five is broader than that: in this picture where the location is at the far eastern edge of the Great Basin, you can see four styles in a number of these flowers. For plants with four or five styles, identification cannot be made based on that characteristic alone.May 4, 2013, Wasatch Front foothills, approx. 5400 ft. elevation, northern Salt Lake County, Utah

This species retains its leaf pubescence on one or both sides throughout the growing year, however, these leaves appear to be glabrous.Amelanchier utahensis Koehne, Sept 26, 2010, Canyonlands, San Juan Co., Utah

While Amelanchier utahensis is reported to occur throughout Utah, its primary distribution in the state is along the Wasatch Mountains and Utah Plateaus and to the east, i.e. the eastern half of the state and particularly in the Colorado Plateau. It is somewhat of an anomaly along the Wasatch Front in northern Utah and occurs only very sporadically in Utah's west desert portion of the Great Basin.More specifically, in Salt Lake County, this is a rarely seen species and where found there often aren't many others. At this location, there was a single plant, the next nearest location that I'm aware of is 1.5 miles south of here at the base of Parley's Canyon, and also at about 1.5 miles north at the base of Emigration Canyon. Plants also occur in the open space within and near Red Butte Garden. Pre-settlement, there were probably occasional plants scattered at somewhat lower elevations.Plants are often shrub sized (this plant was no more than 1 meter tall, but note the herbivory) but then can also grow up to be small trees in the 3 to 4 meters range (Intermountain Flora Vol 3A mistakenly reports its height in several respects). This species tends to be found on dry slopes. It is intricately branched and the bark is reddish until it becomes much older. The branches are unarmed but become quite stiff or at least very tough/dense, and probably would have been useful raw materials for tools and perhaps weapons.May 4, 2013, Wasatch Front foothills, approx. 5400 ft. elevation, northern Salt Lake County, Utah
