Celery has a long fibrous stalk tapering into leaves. Kishu will stalk prey quietly rather than bark. Each leaf is held by a twisted leaf stalk, vertically. When hunting, they stalk their prey or wait for the prey to come to them. The proximal stalk or petiole is called a stipe in ferns. True puffballs do not have a visible stalk or stem. Ancient fishing nets used threads made from leaves, plant stalk and cocoon silk. The flowers form an umbel at the top of a leafless stalk. This allows them to stalk their prey with most of their bodies underwater. Lines and nets were made from leaves, plant stalk and cocoon silk. The fruit is harvested by pulling the pod from its stalk. The leaves of banana plants are composed of a "stalk" (petiole) and a blade (lamina). Fruit remains sessile on the flower stalk. The remaining part of the banana stalk becomes a horsetail. Destroying angels are characterized by having a white stalk and gills.
