l8 7 he Irish Naturalist* January, 



Pottia bryoldesy Mitt. — Amongst old mortar in waste ground, Lis- 

 burn, Co. Antrim. A rare moss for which only one other Irish 

 station is known, that being in Co. Dublin, 



P. intermedia, Furnr.— On decayed thatch, Corbet, Co. Down. 

 Growing in wide patches, and so abundantly as almost to conceal 

 the old thatch of the deserted cottage on which it occurs. A moss 

 perhaps not well understood with us, and of whose Irish distribution 

 little seems to be known. Some localities are given in Fl. N.E.I., 

 but Moore, in his Synopsis, under P. truncaiula, passes it by with the 

 remark — " Gyninostomnvi intei medium , of Turner, is supposed by 

 Mitten to be a gymnostomous st?^tQ o^ P. ianceolaia'"; and, though 

 possibl}' not infrequent, P. intermedia is not mentioned in any of the 

 three lists of Irish mosses that have recentl}^ appeared in iho. Journal 

 of Botany. 



P. minutula, Furnr. — On bare ground, Lenaderg, Co. Down. Rare in 

 Ireland, but perhaps sometimes passed over. When in fruit in 

 August the reddish appearance of the little tufts of this moss at once 

 catches the eye. The time of fruiting is u.sually stated as winter and 

 spring. 



Tortuta marg-inata, Spruce.— On red sandstone walls at Dunmurry, 

 Co. Antrim, where I had the pleasure of pointing it out to Mr. 

 Stewart and the Rev. C. H. Waddell. The locality is about three 

 miles from its only other station in Ireland. 



Barbula lurida, Lindb.— Wall-top by the Newry Canal atScarva, Co. 

 Down. As an Irish plant, heretofore known only from Cork and 

 Kerry. 



B. rlgfldula, Mitt. — Frequent on walls about Lenaderg, Co. Down. 



B. vinealls, Brid. — As was expected, this proves to be much less rare 

 in the North-east than it was previous]}- known to be. It is most 

 frequent about Lisburn, Co. Antrim, and is very abundant ou the 

 north walls of the Lisburn Cathedral. 



B. convoluta Hedw. var. /3 sardoa, B. & S. — On a damp wall by 

 the towing path of the Lagan Canal, near the old corn-mill at Lis- 

 burn, Co. Antrim. Previously reported for Ireland only from Co. 

 Dublin (Dr. Taylor). A very distinct variety that has been accorded 

 specific rank by various authors. It equates with Tj-ichostomum 

 undatum Schp., and Barbula cotnmutata Juratz. 



Leptodontlum flexifoliuin, Hpe.— Plentiful (in company with 

 Ditrichum /lexicaule) amongst the Portstewart sandhills, Co. Derry. 

 Seems to be very rare in Ireland. 



Weisia crlspa. Mitt.— On rather sandy ground by the approach to the 

 gravel pits at Fairy Well, Lisburn, Co. Antrim. In the only two 

 Irish localities that have been recorded— near Belfast (Templeton), 

 and Kilcullen Bridge, Co. Kildare (R. Brown) (the latter locality 

 noted in Braithwaite's Brit. Moss-Flora, but unknown to Dr. Moore) 

 —it has not been seen, I think, for more than a hundred years. 



W. rostellata, Lindh.— Ou a raised ditch-bank by the side of the field- 

 path as you go from Hallymacash to Kiiockmore, near Lisburn, Co. 

 Antrim. The only Irish station.
