In botany, a sporophyll is a leaf that bears sporangia. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls , or microsporangia and are called microsporophylls .

The method of pollination for Dioon plants, whether by wind or animals, has not yet been conclusively determined. The characteristics of the pollen, such as being light, dry, and present in large quantities, suggest wind pollination, which ...
Early land plants had sporophytes that produced identical spores (isosporous or homosporous) but the ancestors of the gymnosperms evolved complex heterosporous life cycles in which the spores producing male and female gametophytes were of different sizes, the female megaspores tending to be larger, and fewer in number, than the male microspores.
The plant can be found in many areas of the south, central, and midwestern United States. It can often be found growing on the sides of roads, particularly on southern exposures, needing full sun and ample moisture during its short growing season. The mature plants often grow and flower in mowed areas.
