MALUS IOENSIS (Wood) Britton. Western Crab Apple. (× 1/2.)
Malus ioensis × lancifolia n. hyb. Specimens collected by Deam in Grant County in 1907 and Huntington County in 1919 appear to be this cross. It would be strange indeed if such closely related species as these Malus and many Cratægus would not cross.
