Notes on the Flora of the North-east of Ireland. 37 



Elatine hydropiper, Linn.— In Loughbrickland, Co. Down, Rev. 

 H. W. Lett, 1886, and subsequently. A new locality, and the only one 

 in Ireland where this plant has been found recently. Mr. Praeger, when 

 examining the duplicate specimens in the immense herbarium of Dr. 

 J. Boswell Syme, now in the possession of Mr. F. J. Hanbury, F.L.S., 

 London, found a number of sheets of Irish specimens of this plant. 

 They are labelled, "Lagan Canal near high-tide water-mark, County 

 Antrim, coll. August, 1847, and comm. by Dr. Mateer." This is, no 

 doubt, the station " near Belfast, Dr. Mateer," published in Flora of Ulster, 

 but which was discredited by the compilers of Flora N. E. Ireland, as vague 

 and unreliable. Mr. Lett's new station, and Mr. Praeger's discovery are 

 most welcome contributions to our knowledge of the local history of this 

 very rare plant. There can be no doubt that it is now extinct in its 

 Belfast station. 



Sagina cillata, Fries. — Very sparingly on sandhills at Newcastle, 

 Co. Down, S. and P. An addition to the flora of the county. 



Spergularia rubra (Linn.), Persoon — Abundant on thedamp margin 

 of Lough Islandreavy, Co. Down, S. and P., 1890. Very rare in district 

 12, and not known elsewhere in the county. 



Lavatera arborea, Linn. — Summit of an isolated sea-stack on the 

 shore of Rathlin Island, R. LI. P., 1892. No doubt native here. 



Hypericum quadrangulum, Linn. var. macu latum Bab. — Lane 

 at Marino station, Holywood, R. LI. P., 1892. New to the Co. Down 

 flora. 



Hypericum elodes, Huds. — Peaty marsh near Colligan Bridge, and 

 several other places in Mourne Mountains, S. and P. Ballyarnott race- 

 course, Co. Derry, Mrs. Leebody, 1891. 



Geranium perenne, Huds. —Roadside near Whitewell quarries, 

 W. D. Donnan, 1890. A new county record. 



Erodium moschatum, L'Herit. — Annalong, Co. Down, H. C. Hart, 

 Proc. R.I. A., 1884, and subsequently, S. and P. Waste ground near Kil- 

 lough, R. Hanna, 1893. 



Rhamnus frangula, Linn. — Re-discovered (a good number of 

 bushes) in Shane's Castle woods by Prof. R. O. Cunningham, 1890. 



[Ononis spinosa, Linn., has not been re-found in Co. Down, and was, no 

 doubt, a casual.] 



TrifoIIum hybridum, Linn. — Frequent in sandy, cultivated fields, 

 and waste ground, and though without claim as a native, is thoroughly 

 established as a colonist. 



Prunus cerasus, Linn. — Near Annalong, Crossgar, Downpatrick, 

 and Crawfordsburn, Co. Down, also Cushendall and Ballycastle in Co. 

 Antrim, and Draperstown in Derry, R. LI. P., but not considered a 

 native. 



Poterium sanguisorba, Linn. — Plentiful in a meado w at Glenm ore, 

 near Lisburn, J. H. Davies, 1891. This is a limestone species, not known 

 elsewhere in the north-east, and a doubt has been expressed as to whether 

 the plant is a native here. 



Sanguisorba officinalis, Linn. — Abundant and luxuriant on rail- 

 way bank near Donaghadee, J. H. Davies, June, 1S93. Interesting as 

 confirming former records, and widening the Co. Down locality of this 

 plant, so rare in Ireland. 



Potentilla tormentilla var. procumbens, Sibth. — On the area 

 in front of the Belfast Museum, S. A. S. Kilbroney and Newcastle, S. 

 and P. Marino, Co. Down, R. LI. P. 



Agrimonia odorata, Mill. — Roadside at Steamboat-quay, Down- 

 patrick, R. LI. P. 1889.
