Reproductive morphology of the lycophytes. Lycophyte sporangia are stalked and kidney-shaped, as in the zosterophyllophytes. In the earliest lycophyte groups, such as the Asteroxylales, the sporangia are oriented across the leaf, so that the widest dimension of the sporangium is perpendicular to the axis of the leaf. cross section of a member of the order Lycopodiales is shown above. You can see the large red xylem cells because they have been stained with a chemical which sticks to the lignin in the cell walls of that tissue. Notice that there are other kinds of tissues among the xylem.
