12 The Irhh NaiuraUst. January, 



Grimmia trichophylla, Grev.— Frequent auiongst the hills near 

 Lisburn, Co. Antrim, and fruiting in some of its localities. Mr. 

 Stewart (in I-l.N.E.f.) records it only from Co. Down, and it seems 

 to be rather rare in Ireland. 



C. HartmanI, Schp. — On stones in a shady lane on the southern slope 

 of Whitemountain, Co. Antrim. The characteristic clusters of curious 

 gemniJE on the leaves are very numerous in all the specimens that 

 were gathered. There seem to be but two other stations for this 

 plant, Galway {Moorcy 1872), and Fairhead {Dixon, 1891). 



Tortula papillosa, Wils. — On trees in the avenue of Edeuderry 

 House, Co. Down. 



Barbula cylindrica, Schp. — Fruiting in quantit)' on a wall at Lisna- 

 garvey, Lisburn, Co. Antrim, and on rocks by River Lagan above 

 Lisburn, Co. Down. Not infrequent in a barren state, but very rarely 

 fertile. 



B. vinealis, Brid. — Amongst Zygodon viridissinius on an Ash tree at 

 Drumbridge, Co. Antrim. Mr. Stewart knew of satisfactory speci- 

 mens from only one place in the North, but is probably right in his 

 supposition that it occurs elsewhere. 



Welsia tenuis, C. M. — Sparingly on the red sandstone at Derriaghy, 

 Co. Antrim. This very prett}^ little moss seems rare in Ireland. 



W, vcrticillata, Brid.— On dripping limestone by the Ulster Canal, 

 Benburb, Co. Armagh. 



Trichostomum mutabile, Bruch, var. littorale, Dixon. {Mollia 

 littoralis, Braithw.) — In crevices of rocks in the stream above Colin 

 Glen. Co. Antrim. 



T. tenulrostrc, Lindb. — Damp stones, River Lagan, Lisburn, Co. 

 Antrim. Noted as rare in the North, but probably sometimes passed 

 over on account of its likeness to other mosses. 



Orthotrichum rupcstre, Schleich.— On granite, Glasdrumman, Co. 

 Down. 



O. affinc, Schrad, var. /3 rivalc, Wils.— At roots of Alder, liable to 

 • be submerged, by the side of River Lagan, above Lisburn, Co. 

 Antrim. This variety does not seem to have been distinguished in 

 Ireland before 



O. tencllum, Bruch On a large Ash tree on the left bank of the 



Bann, a little below Moyallon, and on Ash by the Saintfield road 

 near Lisburn, Co. Down. In the North there was only one station — 

 also in Co, Down— and the species seems to be rare elsewhere in 

 Ireland. 



Splachnum aiYipulIaceum, Linn — Whitemountain, Co. Antrim. 



Ephetnerum scrratum, Ilanipe, var. /^ angustifolium, B. 

 and S.— Bank on the left-hand side of lyongstone Lane, Lisburn, Co. 

 Antrim, April, 1901. The variety is even more minute than the 

 type, and differs so much from that that Dr. Braithwaite, in British 

 Moss Flora, accords it specific rank as E. mimitissimum, Lindb. So very 

 inconspicuous is it— one of the smallest of our British mosses— that, 

 were it not for the green, confervoid protonema which catches
