Friday Fern #16

Let's go with these random no-id ferns I bought the other week then. So despite them all being labelled Pteris there is no way they're all one genus. And the moment I started looking up popular houseplant ferns, and found a few Pteris it was obvious in the sort of way that Blechnum doesn't look anything like Dicksonia. I'm not very good at fern taxonomy yet, but I'm getting a good feel for what certain genera should look like.

So this one was the easiest to identify:


I'm about 99% sure this one is Pteris cretica, but there are so many varieties that I really don't want to try to narrow it down unless someone owns this very variety and wants to pass on the knowledge. I'm usually happy with genus and species to be honest...


This one looks like Adiantum cunninghamii, but after my trip to Wisley today where I saw an identical one for sale (at an extortionate price), I have identified it as Pellaea rotundifolia. Interestingly enough, it's being sold both as a houseplant and as a hardy fern. I wonder which is more appropriate for it.

And then there's this one.


I have absolutely no idea what it is, whether the fronds naturally point up like that or whether it's in some distress! Anyone recognise it?
