Maybe we should do a comparison of all the little yellow flowers out there, to help keep them straight! They’re all different! This is a trailing vine, kind of like a wild strawberry plant. It has compound leaves with 5 toothed leaflets — cinquefoil is an anglicized version of cinq feuilles (French for five leaves). It has 5 petals on the blossom. The blossom grows on a long stalk from the axil. Rose family. Photo: May 27, 2013.
