Woynar A southern sub-Atlantic species which reaches its northernmost location in Britain (v.c. 95). Its distribution, whilst to some extent locally governed by an edaphic requirement of base-poor soils, indicates an optimum in areas with a warm wet winter. It is often a hedgerow plant in the south. It may be distinguished by the basal pinnae which are long, spreading and pinnate. The spores are smaller than P.aculeatum(ay. 30.5m) with a winged perispore (A.Sleep, pers. comm.). 1 2 3 4 6 6 o .:ty: :0a 06 40 00 0 : 41 Os 0441 45 41. Os 060 ... .. 044 n : .

D.oreades is frequently a scree plant and is found also on mountain ledges and in gullies. It is replaced by D.pseudomas on cliffs and gullies facing the sea suggesting that it may be a plant of nutrient-poor situations. All records have been seen by H.V.Corley or C.R.Fraser-Jenkins.
