noun, plural: petiolate plants
(botany) Any of the group of flowering plants that possess petiole, which is a leafstalk that connects the leaf blade to the stem.
The flowering plants may be categorized into two groups based on the presence of petiole.
A petiolate plant is one that has leafstalks or petioles that attach the leaves to the stem.
This is in contrast to sessile plants lacking petioles; hence, their leaves are attached directly to the stem.
