Petiolatus
/pet-ee-oh-LAH-tus/🏷️ Taxonomy●● Intermediate
Also known as: petiolata, petiolatum
A morphological epithet indicating the leaf has a clearly developed petiole — a stalk connecting the blade to the stem. It is used to distinguish stalked-leaved species from sessile-leaved relatives in the same genus. Appears as petiolatus (masculine), petiolata (feminine), or petiolatum (neuter).
Etymology
From Latin petiolus (a little stalk, petiole), diminutive of pes/pedis (foot) + -atus (having).
Example
“Carex petiolata and Asarum petiolatum both have clearly stalked leaves that distinguish them from the short-stalked or stalkless relatives with which they might otherwise be confused.”
