× Amelasorbus
genus of plants

× 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. 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. 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.
“× Amelasorbus” enters the record as genus of plants. Crown Archives preserves that source wording while asking what Amelasorbus, genus and plants can confirm, complicate or overturn.
Why this record matters
“× Amelasorbus” is worth following because a concise public description often conceals a longer documentary argument. Here, Amelasorbus, genus and plants provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q6175001. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1925.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
