this is the second time i bought a fern and i currently have 2 asplenium cobra, an Asplenium nidus cv plicatum, and a new fern.
here's the picture. (sorry for the bad picture)
the one who sold it doesn't have an iota of an idea what it is.
the fern stalk appears to be crunchy and easy to break, and covered with spines (i'm suspecting some of its fronds plastered broke prior to when it got into the garden stall where i bought it)
it wasn't expensive as it's worth only 5$ and the deal felt like a bargain.
