Swamp rose leaf (left) and stipules (above). To identify swamp rose, look for very narrow stipules. Stipules are small, leaf-like appendages at the base of a leaf stalk. In roses, a pair of stipules usually extends along the leaf stalk from the base nearly to the first leaflet (arrow). In swamp rose, the stipules are very narrow; they barely extend out from the leaf stalk until they flare out at the end. Compare these to the wide stipules of Virginia rose.
