MEETING AT GLENDALOUGH 22nd JUNE 2013
A group of eight people overcame the showery weather, the midges and tourists and had a very enjoyable morning look at ferns on the acidic soils of Glendalough above the upper car park.
was an ideal time to view ferns in a pristine state with some fronds still
unfurling and others displaying the early stages of spore development.
‘Tougher’ ferns such as Pteridium
aquilinum (Bracken) extended to the higher/more exposed slopes and others
such as Dryopteris aemula (Hay-scented
Buckler-fern) were in the more sheltered and warmer areas. The ferns seen
included the Dryopteris affinis
(Golden-scaled Male-fern) group with profuse golden scales on the rhachis (stem)
and black ‘dots’ at the junction of branches with the stem; the tripinnate Dryopteris dilatata (Broad Buckler-fern) with the horseshoe shaped
indusium (containing spores) underneath; the delicate Athyrium filix-femina
(Lady-fern); Oreopteris limbosperma
(Lemon-scented Fern); and the dioecious Blechnum
spicant (Hard-fern) with separate female and male fronds. Polypodium (Polypody)was present on oak as an epiphyte and Asplenium
trichomanes (Maidenhair Spleenwort) and Asplenium
adiantum-nigrum (Black Spleenwort) on the walls of the ruined church. The
lime-loving Asplenium ruta-muraria
(Wall-rue) was observed on the mortared wall at the entrance to the car park.
