Re-directed due to name change from Ceterach officinarum to Asplenium ceterach

There were beautiful examples of this fern to be seen growing from cracks and in the grikes of the limestone pavement all over the Burren. The young whitish coloured spores on the backs of the young fronds (LHS) turn red when mature (RHS) giving Ceterach officinarum its English name of Rustyback.

This fern is common all over Ireland and in the south west half of England including all of Wales. It does occur elsewhere in mainland Britain but in smaller numbers and hardly at all in central and northern Scotland.
