Both after Renault. of Renault's " stamens" as itself constituting a male " flower," the stalk on which the pollen-sacs are borne thus representing a pedicel, and not a filament, while the pollen - sacs are themselves the stamens. On this view there would be a certain resemblance to the male flowers of Gnetaceae. In Gnetum, for example,.
