stipule

stipule A leafy or linear appendage, found, usually in pairs, at or near the base of the petiole of a leaf. Stipules are often variously patent (i.e. spreading), but may be adpressed to petiole or twig. Occasionally they are amplexicaul (i.e. surrounding and clasping the twig). These uncommon positions are valuable aids to plant identification.
