The similarity of these simple fertile spikes to those of the smaller species of Ophioglossum, such as .0. Bergianum, is plain enough: if we imagine the sporangia in this plant to be somewhat more prominent, less bulky, and their position slightly altered, so as obliquely to face the sterile frond, the result would be such a type as is seen in the simplest forms of Botrychium.
