 Strobili bearing microsporangia are called "microsporangiate strobili" or "pollen cones", and those bearing ovules are "megasporangiate strobili" or "seed cones" (or "ovulate cones").Cycadophyta are typically dioecious (seed strobili and pollen strobili are produced on separate plants).The lateral organs of seed strobili are megasporophylls (modified leaves) that bear two to several marginal ovules.
