Two of the eight are Western and Alpine, thus showing that some- 
thing may yet remain to be done in the mountain botany of this 
country. 
Pour ai-e E^stern^. three of them having been found on the coast of 
Wicklow, within a short journey from Dublin. Of these, Trifolium 
glomeratum- is. the only species of our present addenda which belongs to 
"Watson's Germanic or South-eastern, type. 
Braba rupestris. is given in the seventh edition of "Withering's 
"Botanical Arrangement," as found plentifully in Leitrim and Sligo by 
Mr. E. Murphy; h\it2i% Braha incana was not recorded by Mr. Murphy, 
though it is abundant on these mountains, while J), rupestris is very 
scarce, there is reason to fear a mistake was made in the name. 
Qalium eruciatum^ long ago recorded in Harris's Ancient and 
Modern state of the County of Down," as occurring near the Cathedral 
at Downpatrick, had quite escaped our notice, as it had that of Mackay ; 
but having ascertained that it still grows in this locality, and has 
recently been found at Colebrooke, Fermanagh, we are very glad to 
restore it to its proper place in the Flora. 
Byrola rotundifolia was included in How's ^'Phytologia Bri- 
tannica" so long ago as 1650, as having been found by Mr. Heaton in 
a' bog by Roscrea, in the King's County, a. locality not yet verified,, 
but which may prove correct, though in all other instances, except at 
Multyfarnham, we have satisfied ourselves that either P. media or 
F. minor have been gathered in. the alleged. Irish localities for ro-. 
tundifolia,. 
Natives^ hut doubtful as species 3, 
Thalictrum Kpchii Epilobium tetragonum (verum.) , 
Potamogeton Lonchites. 
The first two are critical plants, and would no doubt be classed aa 
varieties by a great many botanists. Botamogeton Lonehites (Tuck) is 
a new name applied by Dr. Boswell Syme to the Botamogeton from 
the River Boyne, which we referred doubtfully to B. heterophyllus ; 
and if correctly identified with the American species, this is one more 
American plant occurring in Ireland, though found nowhere else in 
Europe: but it is difiicult to. feel quite sure, when dealing with a genus 
of plants so variable and so little understood as the Botamogetones. 
Blants prolahhj introduced ^ 3. 
Erysimum cheiranthoides. Mentha sylvestris. 
Tamus communis. 
The first two have already been admitted in the works of Mackay 
aad others ; but we now for the first time are able to give satisfactory 
localities. It is surmised that Tamus communis was planted at Hazle-^ 
wood by the late Mr. Wynne.
