A New Irish Moss. 



The discovery iu Ireland of a moss hitherto known only as a native of 

 North China will, I think, interest every Irish botanist. In >May, 1908, 

 while on a visit to the Rev. C. H. Waddell, Vicar of Saintfield, in the 

 County of Down. I picked up a stnall tuft of a Catharinea, which has 

 since turned out to be the rare species C. rhystophyllr of C. Mliller. And on 

 5th February of the present year I paid another visit to my good friend, 

 and was lucky enough to gather some more of this moss. There is a 

 short account of it, and a comparison with an allied species also from 

 China, in Jounial of Botany^ vol. xl p. 2. It comes near C. angustata, which, 

 though found in six Hnglish and one Scotch county, has not yet been 

 met with in Ireland. It was growing iu a turf or sod on the mud-capped 

 top of an old stone fence, in association with Ceratodoii purpurcimi and 

 S/ereodou ciipressiforntc, and at first sight bore a superficial resemblance to 

 PoIyh-ichiiDi aloides. Mr. H. N. Dixon ver}' kindly verified my specimens. 

 Ireland being such a paradise of Mosses, it is likely that we shall soon 

 hear of C. augiistata having been collected in it, and there is every reason 

 to suppose that rhystophylh? will turn up in other localities in addition 

 to Saintfield.

Chenopodium polyspermum Linn, on the shore of Lough Neagh. 



On the 28th August, 1906, I obtained a number of specimens of this 

 species growing among shingle on the shore of Lough Neagh near 

 Ardmore Point, a few miles south of the town of Antrim. Specimens 

 were sent to Dr. Rendle of the British INIuseum, who confirmed m}' 

 identification. There are several old records of its occurrence in Ireland 

 given in Cybele Hibcrnica. More recently in the Irish Naturalist for June, 

 1906, it was recorded by Miss Knowles as occurring among a number of 

 aliens collected at Straffan in Co. Kildare.

The Co. Sligo record for the above species, p. 56 ante, is inaccurate, and 



is probably a slip of the pen. I find the specimens sent to Mr. 



Woodward trom Dublin INIuseum, were collected by myself at Brown's 



Bay, near Lame, Co. Antrim, in 1899. I never collected at any locality 



of that name in Sligo.
