|discussion=<p><i>Ceratopteris pteridoides</i> is usually easily recognized by its sterile leaf morphology, which varies considerably with habitat. Leaves intermediate between sterile and fertile are fairly common, with various degrees of laminar development of the fertile segments. Some fertile leaves have quite broad segments with rows of sporangia along the margins only. <i>Ceratopteris pteridoides</i> is sexual and diploid and is incompletely reproductively isolated from the diploid <i>C. richardii</i>. Hybrids synthesized by L. G. Hickok (1977) result in 40% viable spores.</p>
