Stipe
(from stipes, a stalk). A term used in various senses, viz.: 1. The erect, cylindrical stem of a Palm or of a Tree-fern, bearing the persistent leafstalks, or the leaf-scars; in this sense it is equal in meaning to "caudex." 2. A prolongation of the floral axis between any two whorls of a flower, e.g., between the calyx and corolla (as in Silene), when it is better called "Anthophore," or between the stamens and pistil (as in Geum rivale), forming a "Gynophore," or, when the fruit is ripe, or "Carpophore." 3. The stalk that supports the pileus a cap of Mushrooms (which see). 4. The leafstalk in Ferns.
