Asplenium x sarniense   Guernsey Spleenwort RR DD N

Asplenium x sarniense

This hybrid between Asplenium adiantum-nigrum (Black Spleenwort) and Asplenium obovatum (Lanceolate Spleenwort) was unknown to Science until as late as 1971 and is a sterile hybrid between these two very similar looking Spleenworts. This one was hidden deep in a bank of vegetation and it was quite surprising that it had survived. Quite a few hybrids have been found in Guernsey, all different and some needing microscopic examination to prove they are hybrids and not A. adiantum-nigrum.  

Stace does not mark this as rare but it must be surely?

One of the questions we field botanists ask each other when confronted with a plant difficult to identify such as this is:  

If I saw it again would I recognise it?     Answer: Probably not....
