waterfall in upper Colin Glen ; S.A.S., 19tli June, 1876. 

 Occurs here only on concealed sloping sides of rocks — not on exposed 

 surfaces. The only Irish locality. 



2. S. pusilla (Ehr.) Br. (^ Schimp. 



Damp Chalk rocks, forming a bright green crust on their shaded sides 



—rare. Fr. April — Aug. 



Antrim — In dense patches on the white limestone in the neighbourhood 

 of Belfast {Templeton) ; Muse. Brit. Near Belfast {Temple- 

 ton) ; Flor. Hih. Limestone rocks near Belfast ; T. Brum- 

 mond, op. cit. Limestone of Sallagh Braes, and not infrequent 

 on limestone in Co. Antrim ; D.M. In considerable abundance 

 on white limestone rocks above the mill at Wolfhill, fruiting 

 in May, 1837, also on shady limestone rocks above Lisbum ; 

 Moore, Proc. E.I. A., 1872. Belfast (Dncmmond) ; Brit. 

 Moss Flora. Limestone rocks at Windy Gap, and in several 

 other places on Black Mountain north and south of Whiterock, 

 also in Crow Glen, Carr's Glen, and Eedhall Glen ; S.A.S. 

 Chalk rocks at foot of Sallagh Braes ; C.H.W. 

 First found in Britain by Mr. Templeton, in the Belfast Hills. 



3. S. calcarea (Dicks.) Br. (f- Schimp. 



Damp Chalk rocks, but more often on detached stones where overgrown 

 by grass — very rare. Fr. March — June. Occurs in much smaller 

 patches than the preceding. 



Antrim — On small pieces of white limestone on Black Mountain, both 

 north and south of Whiterock, also on chloritic limestone by 

 the stream above the waterfall in upper Colin Glen, and on 

 Chalk rocks in Carr's Glen ; S.A.S. 

 Under Smith's name, Grimma calcarea, this was given as an Irish plant, 

 by Dawson Turner in 1804, but as no definite locality was stated, and as 

 the preceding species was omitted by Turner it seems to have been 

 assumed that his record was erroneous, and it has been ignored by sub- 

 sequent writers. In Mr. Templeton's copy of Muscologia Hibernica, now 

 in the possession of Mr. R. M. Young, there is a M.S. note by Temple- 

 ton which mentions the finding of this plant on 27th April, 1800, but no 

 special station is assigned. As this, and the preceding species grow in 

 close proximity it is highly probable that he found both, and was there- 

 fore also the first to discover this moss in Ireland.
