===Leaves===
The [[leaves]] are generally arranged [[phyllotaxis|spirally]], but have an opposite arrangement in some species. They can be simple or [[Pinnation|pinnately]] compound (either odd- or even-pinnate). Compound leaves appear in around 30 genera. The leaf margin is most often serrate. Paired [[stipule]]s are generally present and are considered a primitive feature within the family, though they have been independently lost in many groups of Amygdaloideae (previously called Spiraeoideae).<ref name="Potter" /> The stipules are sometimes adnate (attached surface to surface)<ref name="Beentje">{{cite book |last=Beentje |first=H. |title=The Kew Plant Glossary, an Illustrated Dictionary of Plant Terms |publisher=Kew publishing |year=2010 |isbn=978-1-842-46422-9 |location=Kew, London, U.K.}}</ref> to the [[Petiole (botany)|petiole]]. Glands or [[extrafloral nectaries]] may be present on leaf margins or petioles. Spines may be present on the midrib of leaflets and the rachis of compound leaves.
