Discussion

Variety wellsii is known from the Okanagan drainage, where it is usually, but not always, local in occurrence; it is less common than var. okanaganensis. Variety wellsii has been occasionally recorded with pink anthers; it is very distinct with its unusual, differently lobed leaves; it also differs in fruit shape and presentation, fewer pyrenes, and fall foliage color crimson or pink burgundy versus copper bronze in var. okanaganensis. Pomes tend to be duller or deeper red than those of var. okanaganensis at the same date in late August; in mid August they are also brilliant scarlet. The most extreme form of this variety, virtually thornless, is found at Palmer Lake, northern Washington.
