This is an old picture, taken in 1969 and digitized by taking a picture of the original slide with my digital camera. This is only part of the slide image.
Enough apologizing for the quality of the picture. This is a Ceratopteris variety I had at the time with large leaves that had only a few incisions. Unlike Biker's picture of C. pteridoides, this plant did not develop swollen petioles. It is similar to Biker's plant in that it has large leaves that are not deeply divided and that it prefers to grow floating. My plant was different in that the leaf edges were rounded and the petioles were not swollen.
