August, 



Fossombronia cristata, Ivdbg.— This was growing abundantly 

 on the shore of Lough Briclan, close to my residence, where I discovered 

 it in October, 1890 (Pearson, Hep. Brit. Isles, p. 420), but though I have 

 kept a look out every year since, I have not been able to find even one 

 plant. It grew on a whitish deposit of clay left exposed by the falling 

 water in the summer, which would not have been accessible that 

 autumn had it not been a very dry one. 



CoIui*a calyptrifolia (Hook).— Co. Down, Mourne Mountains, 

 Slieve Donard, 1899, Lett. This also I have added to the Ulster flora. 

 It grows on the perpendicular face of the rocks in the chasm into which 

 the streamlet falls at the Black Stairs, associated with Lejeunia hamatu 

 folia, Lejeunia ovata, and Frullania fragillifolia. 



Lejeunia flava (Sw.). — The plant so named from Co. Donegal, 

 contributed two years ago to the Moss Exchange Club, was L. serpyllifolia 

 V. heterophylla, Carr. ; L. Jlava has not hitherto been found anywhere in 

 Ireland outside of Co, Kerry. 



IVIadotheca laevigrata (Schrad.). — Co. Antrim, Drumnasole, 1890, 

 Rev. S. A. Brenan ; Co. Tyrone, Benburb, rocks below the castle, 

 1880, Lett. Glenarm Park, 1895, Lett and Waddell. This plant is not 

 mentioned in the Flora of the North-east of Ireland (1888), nor in the 

 Supplement to same (1895). The above appear to be the only records of 

 it from Ulster. 



Diplophyllutn obtuslfollum (Hook.).— Co. Armagh, Camlough 

 Mountain, Carrififkeeny, at 800 ft., August, 1904, Lett. Another 

 addition to the flora of Ulster. In hollows on the shady, vertical 

 face of an earthen fence. Growing along with Dip. albicans, Webera 

 sessihSy Dicranella heiero?nalla, and Scapania compacta. 



Dlplophyllum dicksoni (Hook.)— Co. Down, Mourne Mountains, 

 Shanlieve, at 1,500 ft., 1898, Lett. Co. Louth, Carlingford Mountain, at 

 1,400 ft., 1900, Lett and Waddell. Co. Donegal, Slieve League, 1902, 

 Lett ; (/. Bot., Nov., 1903). I am not aware of any other notices of this 

 rare plant having been collected in Ulster. 



Scapania calclcola (Arn. et Pers.)— Co. Derry, Magilligan, 1900, 

 Lett and Waddell. On heathy mossy patches at the edge of damp spots 

 amongst the sand dunes. The fine sand of this place contains a large 

 proportion of sea-shell dust, which accounts for the presence of this and 

 the moss Entodon orthocarpics, Ldbg., both plants being calcicolous. This 

 is an addition to the flora of Ireland. There is an interesting account 

 of it by Prof. Douin, of Chartres, in the Revue Bryologique for May, 1905. 



Scapania curta (Mart.) — Co. Derry, Magilligan, 1900, Lett and 

 Waddell, in damp mossy places amongst the sand dunes near the fore- 

 going species. It was also found in the ravine on Benevenagh Mountain. 

 Co. Donegal, Slieve League, 1902, Lett, (/. Bot., Nov., 1903). 



Scapania compacta (Roth.)— Co. Down, Scrabo Hill, 1903, Lett 

 and Waddell ; in several places on the rocks on the top of the hill near 

 the Londonderry Tower ; Co. Armagh, 1890, Lett, at Carriffkeeny on the 

 north of Camlough Mountain, (M'Ardle's List of Irish Hepaticae.)
