The stipes is somewhat longer than the rachis, and it is of a whity-green colour.
These commence to appear at the uppermost extremity of the rachis.
They are attached to the rachis by a very short and slender stalk.
The ovicells arise from the back of the rachis towards the side.
The ovicells are placed in a single series on one side of the rachis, as in S. digitalis, but are widely different in form.
They are placed all on one side of the rachis, generally in single file, but sometimes in pairs.
Ovicell pedunculate ovoid, adnate to the rachis, with a lateral opening.
The grass head was slowly rotated and shifted sideways until nothing remained but the rachis which was discarded.
Sori numerous, rather near the midvein, stipe and rachis lustrous brown.
Sporangia in oblong sori under a reflexed tooth of a pinnule; indusium broad; rachis dark and shining.
