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.

Hotel at Rostrevor.

Very rare; shady spot behind Mourne

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.

CHARACEÆ.

Nitella opaca, Ag. Pond at saw-mill in Tollymore Park; mill-dam on Burren River; Lough Island Reavy, and in the stream that drains it; mill-race by the Bann above Hilltown.

Chara fragilis, Desc. In Warrenpoint town reservoir.

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.)

Papaver rhoeas, Linn. Newcastle, S. A. S. (Flor. N. E. 1.). A 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. Ll. 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.

Vicia 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.
now, and was probably never there.

The plant is not there

Apium nodiflorum, var. B. 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 Tollymore Park (Wade, Planta Rariores). Probably only a small form of S. virgaurea; 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-idea, 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. ß, 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 District 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, Templeton, 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-femina, closely resembling the form known to pteridologists as Kalothrix.

The frond in Herb. Sloaneanum (vol. 100, p. 52) is figured in Plukenet's Phytographia (p. 282, fig. 3), and described by Petiver in his Almagestrum (p. 250), the locality of West Indies, which is given on the page mentioned, being corrected in the mantissa (p. 78, para. 4) to "ex Hibernia." Ray (Historia Plantarum, vol. iii. p. 79, 1704) gives the mountains of Mourne, in county Down, as the place where the specimen above-mentioned was obtained, Plukenet's figure and description being quoted. In the third edition of Ray's Synopsis (1724) the editor, Dillenius, suggests (p. 127) that the fern may be a cave-grown form of Asplenium adiantum-nigrum. This view is endorsed by Newman, who says (British Ferns, ed. 1844, p. 259): "Sprengel, Willdenow, and Sadler all of them give an Asplenium acutum, which I think must be identical with Ray's Filix minor longifolia."

With regard to the specimen in the Sherardian herbarium at Oxford, Mr. G. C. Druce kindly informs us that it is labelled "gathered in ye mountains of Mourne in ye county of Down." On this label (?in Ray's handwriting) is written: "This is a very rare and elegant plant, and deserves a proper name." Accompanying it is a nature-printed sheet from the same specimen, and probably of nearly contemporaneous date. Sibthorpe, when professor at Oxford (1784– 1795), labelled this specimen "Asplenium adiantum-nigrum, L."

The British Museum specimen, which R. Ll. P. has examined, is practically identical with the Kalothrix form of Athyrium filix-femina, and with the Oxford specimen. Professor Vines writes us: "I have compared the enclosed (a cultivated frond of Kalothrix) with the Sherardian specimen from the Mourne Mountains, and have no hesitation in saying that they are identical, excepting the differences that are to be referred to the fact that one plant is wild and the other cultivated. The Sherardian specimen is certainly 'Kalothrix,' i.e. a barren plumose form of Athyrium filix-fœmina."

Hymenophyllum tunbridgense, Sm.

Growing on trees in Tollymore Park, Ferguson; on Slieve Donard, above Donard Lodge, Dickie (Flor. Ulst.). H. wilsoni only appears to grow in the district and both the above records are believed to be erroneous.
