Osmunda regal Is, Ivinn. N. 



"The Rev, G. Robinson showed nie what might be called a 

 small forest of this fine plant, not far from Magher}^ where it 

 forms large tussacs, like those of Carex panicuhita ; drainage is, how- 

 ever, gradually destro3dng it " (Dickie), Flor. Ulst. Bog at south end 

 of Lough Neagh (Templeton), Ferns of Ulster. Near Maghery, 



B. N. F. C, 1871. "Near Tartaraghan, Rev. G. Robinson!!!" 

 More N.H.K. Not now anywhere so abundant or luxuriant as 

 described by Dr. Dickie, but still frequent on the northern bogs : 

 I found it in a number of places on bogs from Maghery to Lurgan, 

 and also thrown up by the waves on thcvshores of Annagarrifif lake, 

 where it evidently flourishes in security on the islands ; also on a 

 bog south of Portadown ; often in some abundance, but generally 

 rather stunted, R. LI. P. 



Botrychlum lunaria, Sw. N. 



One plant on top of Navan fort, W. F. J. : I have not seen 

 Mr. Johnson's specimen, which was not preserved, but he is 

 satisfied that it was right : I failed to refind it at Navan, R. LI. P. 

 Shore of Lough Neagh at Ardmore, H. W. L. spec. ! 



Ophiogrlossum vulgatuin, Linn. N. 



Loughgall near the lake. More N. H. R.\ Armagh (Kinahan), 

 Flor. Ulst. Ardmore near Lurgan ; abundant in short grass on the 

 shores of Lough Neagh, where it is under water for four winter 

 months (Lett), Ferns of Ulster. Tartaraghan, B. N. F. C, 1877. 

 Mullinure and Drummanmore near Armagh, W. F. J. spec. ! 

 Bird island on Lough Neagh shore, R. LI. P. 



Isoetes lacustrls, Linn. — M. S. 



County Armagh, Cyb. Hih. In Cashel lake west of Slieve 



GuUion (444 feet elevation) ; and at the west end of Lough Ross 



near Crossmaglen (286 feet), and on east shore of Mullaghmore 



lough (200 feet elevation), June, 1893, R. LI. P. 



Lycopodium selago, Linn. N. M. S. 



Very rare ; one plant on bog north of Churchhill (under 100 feet) ; 

 summit of Carrigatuke (1,200) ; and sparingly on Camlough 

 mountain, R. LI. P. 



Selagrinella splnosa, Beauv. S. 



On Camlough mountain at about 700 to 1,000 feet, R. LI. P. 



(Pllularla griobulifera, Linn. [N.] 



Abundant in marshy ground two miles from the mouth of the 

 Blackwater, near Lough Neagh (Campbell), Flor. Hib. and Flor. 

 Ulst. This station may be in Armagh, or in Tyrone, but is not in 

 district 12, as given in Cyb. Hib. I did not meet with the plant, 

 and it is apparently one of these which the drainage of Lough 

 Neagh has forced from its former habitats.) 



Chara fragills, Desv. N. 



Lough Neagh at Ardmore Glebe (f. dclicattila) and Bird island, 

 H.W.L. spec ! In Lough Neagh at Ardmore Point (form approach- 

 ing delicattila), and at Maghery ; pool beside Derrylileagh lake ; 

 lake at Tynan Abbey; and bog-holes south of Portadown (form 

 with prominent primary cortical cells), R. LI. P. 



C. aspera, Willd. N. 



In Lough Neagh at Derryadd Bay ; Ardmore Point (f. lacustris), 

 and Maghery (f. subinennis) ; quarries near Navan fort, R. Ll. P. 



C. aspera f. lacustris and C. fragilis f. delicatitla grow abundantly in 

 shallow water on the gravelly shores of Lough Neagh, where they 

 may be observed covering the bottom with short bright green tufts. 

 After storms they are cast ashore in large quantities, mixed with 

 Nit el la opaca.
