Female Z. integrifolia with mature seed cone and new cone emerging from base. Zamia species often produce more than one cone close to the tip of the stem or at the terminal of the caudex where it intersects with the aboveground stem. The cones, also called strobili, of Z. integrifolia are dioecious. The male strobilus and the female strobilus ...
Strobili are often called cones, but some botanists restrict the use of the term cone to the woody seed strobili of conifers. Strobili are characterized by a central axis (anatomically a stem ) surrounded by spirally arranged or decussate structures that may be modified leaves or modified stems .
In some (e.g. firs and cedars), the cones disintegrate to release the seeds, and in others (e.g. the pines that produce pine nuts) the nut-like seeds are dispersed by birds (mainly nutcrackers, and jays), which break up the specially adapted softer cones. Ripe cones may remain on the plant for a varied amount of time before falling to the ...

The stem is normally divided into nodes and internodes: [2] The nodes are the points of attachment for leaves and can hold one or more leaves. There are sometimes axillary buds between the stem and leaf which can grow into branches (with leaves, conifer cones, or flowers). [2]
