A leaf or leaf part (typically at the base) that partially or fully clasps the stem above the node is a leaf sheath, such as in the Poaceae (grasses) and many Apiaceae. A pseudopetiole is a petiole-like structure arising between a leaf sheath and blade, found in several monocots, such as bananas and bamboos.
