Alniaria yuana (Yu's Whitebeam) (Spongberg) Rushforth 2018
plant species in the rosaceae family
Alniaria yuana, (syns. Sorbus yuana, Aria yuana) Yu's whitebeam, is a species of flowering plant in the family Rosaceae, native to Chongqing, and western Hubei, China. Rare in the wild, it is usually found on steep ravine slopes over 2,000 m (6,600 ft) in elevation. A shapely tree reaching 15 m (50 ft), with white flowers, red fruit, and yellow autumn foliage, it appears to be resistant to fire blight, and so is a good candidate for further development as an ornamental. It is used as a street tree in Aarhus, Denmark.
