71 



a large patch of the species in its normal state on Howth, by Mr. D. Orr, 

 in April, 1856. 



The following species of Mosses, not hitherto recorded as Irish, have 

 been discovered and identified since I furnished the last supplementary- 

 list in the "Journal of the Royal Dublin Society" (vide vol. i., 1857). 



Sphagnum contortum (Schultz). Black-stemmed Bog Moss. 



Habitat : "Wicklow Mountains ; Mr. J. H. Davies, of Thirsk, York- 

 shire, who appears to have been the first to recognise this species in 

 Ireland, and who lately sent specimens to me gathered in "Wicklow. 

 The plant, however, is not rare, since I find it in my herbarium, col- 

 li from bogs in the North of Ireland twenty years ago; and Mr. 

 D. Orr has it from the Three-Rock Mountain, Co. Dublin, and also from 

 Howth, as well as the variety 7. obesum from the latter place. 



Orimmia Schultzii (Bridel). Schultz's Grimmia. 



Habitat: on granite rocks near the Scalp, Co. Dublin, July, 1854; 



Mr. D. Orr. This plant we had for some years considered to be only 



mi a tricophylla, to which species it bears strong resemblance ; but 



some doubt having arisen on the matter, specimens were submitted to 



Mr. Wilson, who at once pronounced it his G. Schultzii.
