petiolar's Usage Examples:

anomala petiolaris) - Originating in China and Japan, Climbing hydrangea can reach up to 60 feet, using its stems to cling to walls or other supports.

The petioles have a somewhat complex structure, the bundle often having, in transverse section, the form of an H; it has been proposed to subdivide the genus on the details of the petiolar structure.

In the case of alternate leaves, the stipules at the base of each leaf are sometimes united to the petiole and to each other, so as to form an adnate, adherent or petiolary stipule, as in the rose, or an axillary stipule, as in Houttuynia cordata.
