No he visto que menciones los grandes helechos flotantes que a veces mantenemos flotantes como
Ceratopteris thalictroides conocido como "Helecho de sumatra" o Ceratopteris pteridioides conocido como "Helecho flotante".

Tenéis fotos en su estadio flotante? No encuentro ninguna... :mmm:
Sois cojonudos los dos! :heart:
Todas ellas son Ceratopteris thalictroides? :und:
Hello , pteridoides is often erroneously called cornuta in the hobby. C. pter. grows only as floating or emersed plant, can't be grown submerged. It has coarsely lobed floating leaves and thick petioles, like that: http://intermountainbiota.org/portal/collections/individual/index.php?occid=4138302

Under optimal conditions it can develop finely dissected emersed spore-bearing leaves, but also with thick petiole:

Your fern is a ceratopteris form that's mostly called Ceratopteris cornuta in the trade. Definitely no pteridoides.
However the true identity of the plants traded as cornuta is another issue. Maybe they belong to the C. thalictroides complex, at least in part.
It seems that C. pteridoides is the easiest to recognise Ceratopteris species. But the other C. species such as thalictroides (in the wider sense), cornuta and richardii are difficult to ID, e.g. by spore number per sporangium, or chromosome count.
...now I see that the plantsociety link is a little misleading:
the 2nd and 3rd photo shows really pteridoides. But the 1st pic doesn't show the finely dissected leaves of spore-bearing pteridoides, but a submerged plant of the C. thalictroides complex.

Aqui te dejo unas pocas Ramon, una pena que les acababa de hacer una poda a las partes emergidas, saque un buen puñado de hojas y ya veis que apenas se nota. Un saludo.
