Each fertile leaf or sporophyll subtends only a single sporange, which is borne on the stem above the leaf-axil. The sporanges are of considerable size in proportion to that of the leaf, and are formed from a group of superficial cells at the growing point of the stem. They make their first appearance as flat, afterwards spherical or club-shaped, swellings, completely covered by the epiderm, which subsequently forms, by tangential divisions, the wall of the sporange, composed of three layers.
