Jump to: navigation, search


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.
