The ovulate cone geometry, as a whole, deflects unidirectional wind into cyclonic vortices around the cone axis, each scale-bract deflecting nonimpacted pollen along orthostichies and parastichies. The morphology of the typical conifer ovulate cone is interpreted as a structure that optimizes anemo...
