Discussion

Species 1.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Cyanogenic glycosides are usually present in Amygdaloideae; sorbitol is present.

The name Amygdaloideae Arnott (1832) has priority over Spiraeoideae Arnott (1832), used by D. Potter et al. (2007), because Amygdalaceae (1820) is an earlier conserved name.
