|discussion=<p><i>Ceratopteris thalictroides</i> is common in Florida but rare elsewhere. It is tetraploid (n = 77, 78), the two cytotypes reproductively isolated. It can be distinguished from the diploid <i>C. richardii</i> on the basis of spore number per sporangium. The single population in southern California may have been a recent introduction and apparently has not persisted. Several populations are of hybrid origin, with reduced spore viability and irregular meiotic pairing. These include some in southern Florida and Texas.</p>
