Nephrolepis species have pinules with crenate margins. The pinule margins in the pic look smooth? Could be pic quality?

If there are sori on the leaf undersides, a pic of them would be helpful. Often they are the only way to get to species. The sori will be the answer.

I will photograph whatever be of interest.

With ferns, usually and in this case I am satisfied to know the genus.

Can you verify if the pinule margins are smooth or crenate, and get a pic of the sori. The sori will show the genus. Theres a huge difference between Nephrolepis and whatever the other one was Dicantopteris flexuosa or something close. The Nephrolepis falcata,(Fishtail Sword Fern) is a really cool looking fern. It looks like something that grows in Indonesia.

Definately Nephrolepis and most likely N. cordifolia.
