Schott var. borreri Newm.) An Atlantic species very common in northwest Scotland and the oceanic areas of the British Isles. In lowland and south and eastern England confined to woodlands or shady situations on heavy soils and clays. A combination of clay soils and higher rainfall increases its occurrence in the Weald. The map of this species (21/2) on p. 11 of the Atlas of the British Flora does not show a true picture as many records were registered as D.filix-mas agg. and are shown on Map 21/1-2 only. se Jr ell o o :000 0 00 or 9, 88 o Soe o 4: oil oboi erne tr es. .6 Gee 05is 48° 0 OS 110000 000 004104, 55 w 415 .5 1 2 3 4 5 6 t:22 0 6 5 4 3 2 1 0
ASPIDIACEAE 0 6 5 0 27.4 DRYOPTERIS REMOTA UTM GRID Kkenstres mass 9 9 CHANNEL GLANDS PLOT TED ON 0 WV 41' soo 100 0 8 2 1 2 27.4 Dryopteris remota (A.Br.) Druce 1 2 An apogamous species probably originating from the hybrid between D.expansa and D.pseudomas could be expected where these species grow together. It is, however, rare. Plants brought into cultivation as Lastrea 'boydii' from Loch Lomond appear to be this species but it has not been seen in the wild this century. The two Irish specimens are even more perplexing as D.expansa is so far not recorded from Ireland; both records (Glen Flesk , v.c. H2 and Dalystown, v.c. H15) need refinding (see 3 4 9 8 N1 0 4505; Zs N2 7 4 5 6 A.C.Jermy & S.Walker, in C.A.Stace (ed.). loc.cit.: 115). It is known however, that in Europe D.remota occurs in the absence of either of the above species and probably does not now arise de novo from hybridisation. The hybrid D.austriaca x pseudo mas recorded as D. x woynarii Rothm. from Lochinver, v.c. 108, in A.C.Jermy & S.Walker, in C.A.Stace (ed.) loc. cit.: 115; 1975, is now considered to be doubtfully of that parentage and more likely D. x ambrosiae. 87
