Lastrea oreoptoris, Presl., 20–2000. In some abundance on the lower
grounds along the northern slope of the range from Slieve Donard to Slieve-na-man; plentiful by a small stream east of Kinahalla; sparingly by the Annalong River near Dunny Water Bridge ; glen at Fofanny, banks of Rocky River, and Mill River below Slieve Lamagan ; single plants, mostly seedlings, on cliffs south of Blue Lough (1300), near Cove Mountain cave (1400), cliffs of Eagle Mountain (1600), and slate rocks on Slieve Muck North (2000). L. filix-mas, Presl., 1500. Var. 8 L. abbreviata DC. 1300–1500. Abundant on cliffs of Eagle Mountain, and very distinct; new to district 12. L. dilatata, Presl., 2449. L. æmula, Brack. 100–1430; very local. Frequent throughout Tollymore Park; shady nook on cliffs on east face of Cove Mountain at 1400
feet. Polystichum aculeatum, Roth. Very rare. Sparingly in Tollymore
Park, and in Rostrevor Wood. P. angulare, Newman. Cystopteris fragilis, Bernh., 800-2000. On dripping slate rocks,
Black Stairs on Shanslieve ; N. E. slope of Slieve-na-glough ;
on Slieve Muck north at 2000 feet. Athyrium filix-fæmina, Roth., 2449. Asplenium adiantum-nigrum, Linn., 1600. A trichomanes, Linn.,
1600. A. marinum, Linn. Abundant on slate rocks by the sea,
south of Newcastle. A. ruta-muraria, Linn. Scolopendrium vulgare, Sym. Rare. Ceterach officinarum, Willd. Very sparingly on a wall at Tollymore
House, near Newcastle. Not seen at Rostrevor (Crawford,
Flor. Ulst.) or Bryansford (Thompson, ibid.). Blechnum boreale, Sw., 2449. Pteris aquilina, Linn., 1400. Hymenophyllum wilsoni, Hook., 150–1500. On boulders in the
Shimna and Spinkwee Rivers in Tollymore Park ; N. E. shoulder of Slieve Meel More; abundant on cliffs of Eagle Mountain ; cliffs south of Blue Lough; Hare's Gap; Slieve Beg; Luke's Mountain ; in the cave on Cove Mountain (a variety with branched fronds). Templeton's station, “margin of Cove Lough" (Flor. N. E. I.), is a highly improbable one, the shores being low and swampy. Not observed on Slieve Maganmore (Hart, Proc. R. I. A., 1884).
Osmunda regalis, Linn. On wet rocks only; very rare. Sea-cliffs
south of Newcastle-well established here ; very sparingly by the Bloody Burn; on the west side of Slieve Bingian; and by the Causeway Water. Not seen by the Glen River above Newcastle (Thompson, Flor. Ulst., and Corry, Flor. N. E. I.) nor by the Kilbroney River (Turretin, Proc. B. N. F. C., 1885-6, App.), but we have seen plants obtained at the latter place. Templeton's note, “Donard's Cave in the Mourne Mountains," refers to a seacave at our first-mentioned station ; his record, “margin of a lake south-west of Castlewellan," probably refers to Altnadua
Lake, where, however, the fern is not now to be found. Botrychium lunaria, Sw. Sandhills at Newcastle Railway Station,
and heathy pasture near Bloody Bridge. Ophioglossum vulgatum, Linn. Very rare ; shady spot behind Mourne
Hotel at Rostrevor.

LYCOPODIACEÆ. Isoetes lacustris, Linn, 1100-1350. Abundant in Blue Lough and
Lough Shannagh, and sparingly in Bingian Lough, growing on sand and peat in three to eight feet of water. Very fine specimens
were dredged in Blue Lough in five to eight feet of water. Lycopodium clavatum, Linn. Extremely rare; a single plant on N. E.
slope of Slieve Donard, at 2450 feet. Not seen in Tollymore Park (Dickson, Flor. N. E. I.). L. alpinum, Linn., 1900–2796. Summits of Slieve Donard, Slieve Commedagh, Slieve Bearnagh, Chimney Rock Mountain, Carn Mountain, and Shanslieve ; abundant on the northern slope of Slieve Bearnagh down to
1900 feet. L. selago, Linn., 2796. Selaginella spinulosa, A. Br., 0–2000.

PLANTS RECORDED FROM THE MOURNE MOUNTAINS,
which were not found by S. A. S. and R. LI. P. (This list does not include old records which have already, in Flora N.E. Ireland, been shown to be referable to mistakes, casuals, or escapes.)
Three species, noted as “common” in the Flora of the North-east of Ireland, do not occur in the district :
Geum rivale, Linn.
P. crispus, Linn.
casual in South Down, and not established at any one spot. Cerastium semidecandrum, Linn. Greencastle (Ir. Flor.). Not found. C. arvense, Linn. About Greencastle (Ir. Flor.). Not seen. Trifolium medium, Huds. Newcastle, R. LI. P. (Flor. N. E. I.).
We failed to re-find it in the district. In county Down it is known to grow only on the northern margin, adjoining its Antrim
habitats. Dicia orobus, DC. Orobus sylvaticus nostras, found near Rostrevor,
Dr. Sherard (Raii Synopsis, Ed. II. 1696). Not seen anywhere, and in the north-east of Ireland known only in one station in county Antrim. The plant may have been V. sylvatica. The specimens in the Sherardian Herbarium at Oxford do not settle
the question definitely. Prunus insititia, Linn. Rostrevor Wood (Ir. Flor.). Not found;
probably planted. Rubus villicaulis, W. & N. By the Causeway Water, S.A.S. (Flor.
N.E.I.). Not re-gathered, but the plant was right. R. foliosus, Weihe. By stream in Tollymore Park, S. A. S. (Flor.
N.E.I.). The remark on preceding species applies here also. Pyrus aria, Sm. Brought from off the Mourne Mountains to Lord
Clanbrassil; Templeton (Flor. N.E.I.). Does not now occur on
the range, and appears to be almost extinct in northern Ireland. Saxifraga aizoides, Linn. By the side of the cataract at Donard Lodge,
Thompson and Hyndman (Flor. Ulst.). We have nothing to add to the note on this record in Flor. N.E.I. The plant is not there now, and was probably never there.
Apium nodiflorum, var. ß. repens, R. In marshy places by the river
side at Kilkeel (Wade, Planta Rariores). Not now known in
District 12. Solidago virgaurea, var. y, cambrica, Huds. Banks of the river in Tolly
more Park (Wade, Plantæ Rariores). Probably only a small form
of S. rirgaurea; var. cambrica is not now in Tollymore Park. Anthemis nobilis, Linn. Foot of Tullybranagan Mountain, west of
Newcastle, John White (Wade, Planta Rariores). Most likely a
casual ; our search for this was vain. Hieracium corymbosum, Fr. Banks of Spinkwee River. River at upper
end of Tollymore Park, S.A.S. (Cybele Hibernica, as H. strictum, and Flor. N.E.I.). Only typical H. crocatum could be found there, but the former record was based on the determination of a specimen
by Mr. Backhouse. H. umbellatum, Linn. Rocks, Tollymore Park, Templeton (Flor. Ulst.).
Erroneous determination probably. Arctostaphylos uva-ursi, Spr. Top of Slieve Donard, Dickie (Flor.
Ulst.). Vaccinium vitis-idæa, which, though plentiful on the summit of Donard, is not included in Dr. Dickie's list of summit species,
was evidently the plant intended. Pyrola minor, Linn, Tollymore Park, Dickson (Flor. N.E.I.). May
be right; no species of Pyrola occurred to us. Convolvulus soldanella, Linn. Sandhills on the shore at Newcastle,
Templeton, 1795 (Flor. Ulst. and Flor. N.E.I.). Not there now,
but grows a few miles northward.. Hyoscyamus niger, Linn. About Greencastle, and the tower along the
shore going to Kilkeel (Ir. Flor.). Not refound; it is a capricious
and uncertain species. Melampyrum sylvaticum, Linn. Tollymore Park, Thompson (Flor.
Ulst.). Not seen by us in the district, and not known elsewhere
in the county, Was no doubt a form of M. pratense. Veronica officinalis, var. B, glabra, Bab. Mourne Mountains, near
Warrenpoint, J. White; Templeton (Flor. N.E.I.), Not seen. Mentha pulegium, Linn. Abundantly in wet pastures at the foot of
Tullybranagan Mountain, county Down (Ir. Flor.). Not there
now. Galeopsis versicolor, Curt. Annalong (Hart, Proc. R.I.A., 1884). Not
seen anywhere, and not known elsewhere in county Down; possibly a casual.
Primula veris, Linn. Wood at Rostrevor, Gray (Flor. N.E.I.). Not
refound. We doubt the plant being native here; all the Dis
trict 12 stations are more than suspicious. Beta maritima, Linn. Between Greencastle and Kilkeel, along the
gravelly shore (Ir. Flor.). Not found, but quite probable. Scirpus pauciflorus, Lightf. Shore four or five miles south of Newcastle,
Templeton, 1797 (Flor. N.E.I.). Between Dunnywater Bridge
and Annalong (Hart, Proc. R.I.A., 1884). Not found by us. Blysmus rufus, Linn. Warrenpoint, Robinson (Flor. N.E.I.). We
suppose correct, but not seen by us. Carex rigida, Good. Included by Dr. Dickie (Flor. Ulst.) in his list
of plants growing on the summit of Slieve Donard. Certainly not
there now, and must have been an error. C. extensa, Good. Greencastle and Newcastle, S.A.S. (Flor. N.E.I.).
Not gathered, but doubtless there still. Avena pubescens, Linn. On rough banks south of Newcastle, Temple
ton, 1799 (Flor. N.E.I.). We searched for this unsuccessfully. Koeleria cristata, Pers. High grassy banks above the rocks on the
shore about one mile south of Newcastle, Templeton, 1799 (Flor. N.E.I.). The station is most explicitly defined, but we failed to
find the grass. Poa nemoralis, Linn. In a wood at the side of Knockchree Mountain,
White (Wade, Planta Rariores). Donard Lodge, Thompson (Flor. Ulst.). Woods about Rostrevor, White (Cyb. Hib.). Not found anywhere, nor has the species been seen in District 12 for the last
fifty years. Lolium temulentum, Linn. Fields at Newcastle, Rea (Flor. Ulst.).
Imported with seed, and has not remained. Asplenium adiantum-nigrum, var. Y, acutum, Bory. In a dark cave
among the mountains of Mourne (Sherard, Herb. Oxon.; also Raii Synopsis (Filix minor longifolia, &c.)). We are glad to be able to correct an error of long standing in regard to this fern. The plant which was collected by Sherard in the Mourne Mountains in 1694, and of which fronds are preserved in the Herbarium Sloaneanum in the British Museum, and the Sherardian herbarium at Oxford, was not an Asplenium, but a beautifully-divided plumose barren form of Athyrium filix-fæmina, closely resembling the form known
to pteridologists as Kalothrix. R.I.A. PROC., ser. III., VOL. II.
