The wood itself contained Quercus peduncutata and Fraxinus excelsior (co-dominant in places and largely self-sown), Uhnus montana (self-sown, locally dominant), Prunus spinosa (abundant), Pyrus malus, Cratcegus motiogyna, Corylus Avellana, Ilex aquifolium (self-sown). Viburnum Opulus, Euonymus europceus, Fagus stlvatica in places, Rubus fruticosus (agg.), R. ccesius, Hedera Helix (very abundant), Lonicera periclymenum, Geum urbanum, Viola silvatica (agg.), Circcea lutetiana, Oxalis acetosella.

Geranium Robertianuin, Glechoma hederacea, Brachypodium silvaticum, Bromus asper, the species of Epipactis met with in the hazel-scrub below Slieve Carran, Aspidium Filix-tnas, Polystichum angulare, Polypodium vulgare. Pteris aquilina occurred, but was very scarce. In parts of the wood the oak was dominant and the ash scarce. Although developed over limestone the soil over considerable tracts gave no calcareous reaction, and the general characters of the wood inclined to the oak-rather than to the ash-type. It is, however, quite possible that it has been derived from a wood of the ash-type by continuous accumulation of soil and washing out of lime, and this view is supported by the abundance of ash in parts, and the occurrence of species like the Spindle-tree and the Helleborine, as well as by analogy with various English woods.
