S. pallidum, Fr. ? Slieve League ; specimens insufficient for certainty^ 



S. argenteum, Pr. Carrick river. Mr. Backhouse and Professor 

 Babington, to whom the former desired, me to forward my speci- 

 mens, both agree about this plant, which has not been detected in 

 Ireland hitherto. I have it also fi'om Connemara and Down. 

 Specimens from Glenalla, in Donegal, are doubtfully referred to 

 this species.

^ Of the plants from Carrick river, Mr. Backhouse was doubtful, and wrote, 

 "heads far too numerous for gothicum;'''' hie wrote also, "like S. norvegicimi, 

 Fr.," and requested me to send the specimen to Professor Babington, who pla^-ed 

 them as above.
