× Amelasorbus jackii Rehder |
× Amelasorbus is a flowering plant in the family Rosaceae. A naturally occurring hybrid, it is the result of a cross between two distinct tree genera, Amelanchier and Sorbus, and shows phenotypic similarities to both parents.[citation needed] This type of intergeneric hybrid is quite rare, and is indicated by a multiplication symbol before the name. The name Amelasorbus is an example of a portmanteau word, a combination of the two parents' names.
Species
There is only one accepted species, × Amelasorbus jackii, (Jack's amelasorbus) the result of Amelanchier alnifolia × Sorbus scopulina. A specimen was discovered growing in Idaho, and described by Alfred Rehder of the Arnold Arboretum in 1925.[1] Individuals have also been discovered in Oregon. Due to their hybrid nature, they tend to be quite variable, and this had (mis)led authors to describe other species; × Amelasorbus raciborskiana and × Amelasorbus hoseri, which may or may not be synonyms.
