Last gasps?

Neil has sent me a couple of records from February including this nice patch of Hymenophyllum tunbrigense (Tunbridge Filmy-fern) from the Drinan area – the first record in NG51 since 1995 and in pretty much the same place as one of the two records made than.

Note the teeth on the indusia  – the cover of the sori which contain the sporangia, the spore-bearing structures. This is the best way to distinguish it from the locally common Hymenophyllum wilsonii (Wilson’s Filmy-fern).
