NOTES. 

 BOTANY. 



LIVER WOR TS. 



Ricciocarpus natans, Corda [Riccia natans, Linn.] in Co. 

 Dublin. — While botanizing along the Grand Canal early last month 

 {7th August), I discovered this interesting species growing in great abun- 

 dance in a sluggish ditch, evidently long undisturbed, beside an old 

 grass-grown road near Ballyfermott. The plant, mingled with Lemna 

 minor, extends along the ditch here, at intervals, for more than a hundred 

 yards, spreading its starry root-like processes over the surface of the 

 water in a dark-brown sheet which at once arrests attention. Mr. David 

 McArdle, of the Glasnevin Botanic Gardens, who has kindly examined 

 my specimens and determined the species, assures me that he can find no 

 record of its having been previously noted in the Co. Dublin, and sup- 

 plies me with the following details as to its distribution in Ireland, so far 

 as hitherto made out, the known stations for the species being (i) boggy 

 pool between Navan and Drogheda ; (2) ditch by the side of the Shannon, 

 near Portumna, Co. Galway; (3) near Passy, Co. I^imerick (Dr. Harvey) ; 

 (4) ditch by the River Barrow, three miles below Ath}^ Co Kildare (Mr. 

 R. W. Scully).— Nathan I EI. Coi^Gan, Dublin. 



C L UB -MOSSES. 



Lyco podium clavatum L. in Co. Armagh. — On August loth 

 I received from Rev. H. W. Lett a specimen of this plant, collected two 

 days previously, on Brackagh Bog, south of Portadown, Co. Armagh ; 

 Mr. Lett describes the plant as plentiful in one spot. This is an interest- 

 ing addition to the county flora, especially since the elevation of the bog 

 in question is only fifty feet above sea-level ; in the north of Ireland at 

 least this Club-moss usually occurs on mountain heaths. — R. LIvOYD

PHANEROGAMS. 



Euphorbia cyparissias L. in King's County. — In the early 

 part of this year I received from Miss Margaret Goodbody, of Charlestown 

 House, Clara, King's Co., some imperfect specimens of a plant unknown 

 to her. They were a puzzle to me at the time, but subsequently proved 

 to be the rare and peculiar Euphorbia cyparissias L. On the 23rd May last, 

 I was taken to the spot, and found it profusely in flower and in consider- 

 able quantity, extending along a dry hedge-bank with one or two intervals 

 for about twenty yards. It grows in a lane near Horseleap, about two 

 and a-half miles from Clara, and the only house near it is a cottage, from 

 the garden of which it does not seem likely to have escaped. In the 

 "English Flora" it is looked upon as having been introduced, and no 

 doubt the same applies to the specimen we are now considering, which 

 is however remarkable from its remote situation, and the extent to which 

 it has been established. On finding it, I immediately sent fresh specimens 

 to Mr. A. G. More, and to Mr. Stewart, of Belfast, and have since placed 

 dried specimens in the Herbarium of the Science and Art Museum, Dublin.

The Shamrock. — A Postscript. — In the paper on this subject, 

 published in last month's number of the Irish Naturalist, I omitted 

 through oversight to mention that the plant supplied to me by Mr. Bur-
