Anacharis Alsinastrum in Ireland. 
‘On the Occurrence of Anacharis Alsinastrum in Ireland ;’ by Dr. 
Dickie. 
In a letter to Dr. Balfour, Dr. Dickie observed : —“ The accom- 
panying are, I suppose, specimens of Anacharis. If so, we have in 
Ireland the earliest known record of its presence in the United King- 
dom if I mistake not. I have thought, at all events, it might be a 
point of interest to you, and worthy of notice at your Society.” The 
specimens were accompanied by the following note by Mr. John New, 
gardener :—‘‘ About eighteen years ago, the pond at Waringstown 
was cleared of overhanging trees, when the Anacharis was immediately 
observed after the planting of some aquatics, making it necessary 
several times during the summer to clear it out. It is not known 
whether it existed in the pond previously to the above date, or was 
introduced with the aquatics at that time. For many years its name 
was not known to any person in the neighbourhood.” 
Botanical Trip to the Tents Muir. 
‘Notes of a Botanical Trip to the Tents Muir, in the north of Fife, 
in July last;> by Mr. G. Lawson. 
The object of these notes was to call attention to a rich locality, 
which, although within easy reach, had not hitherto been much 
examined by Edinburgh botanists. The Tents Muir was described 
as an extensive tract, chiefly of sand dunes, extending along the coast 
from Ferry-Port-on-Craig to the river Eden. The pools and moist 
hollows on the Muir were rich in fresh-water Algz, including Nos- 
tochinez and Desmidiez. The party did not find Isnardia palustris, 
and fancied that the abundance and luxuriance of Peplis Portula might 
have led to some mistake. The Peplis afforded a retreat for myriads 
of Hydra viridis. ‘

Edinburgh ;’ by G. R. Tate, Esq. 
The following were among the plants noticed :— 
Alyssum calycinum. On debris below the Queen’s Drive, near 
Duddingston. “TI noticed the plant in this locality in the month of 
May before it was in flower; at that time there were a number of 
specimens. As the season adyanced and the locality became more
