The leaves are crisp and it has stems that are 5-6 inches long. Initailly I thought it is Asplenium nidus but the stems dont seem to be right. The leaves are not growing in a whorl from the center.
Try Asplenium nidus 'Crispy Wave', though I agree the bases of the fern fronds do look more extended than usual. Maybe it was propagated in a low-light environment?
Could we see a photo of one leaf? Are the leaves a single narrow strip, or are they lobed? And are there any hairy rhizomes creeping along the soil?
