Summer annual broadleaf
An annual twining or trailing vine that may reach as much as 3-1/2 feet in
length. Seedlings have cotyledons that are linear and without hairs. Stems are
erect at first, then become twining or creeping and branched at the base. A membranous
sheath (ocrea) surrounds the stem at the base of each leaf petiole, which helps
to distinguish this weed from almost all other vining species that have a similar
leaf shape. Leaves are alternate and triangular to heart-shaped with a pointed
tip. Basal lobes point inward toward the petiole. Flowers are inconspicuous and
greenish white in color.
