ascertain the immense and snrprising abundance of Sisyrhynchium 
Bcrmudiana over the low meadows lying between Woodford and Loiagh 
Derg, in some of which it actually constitiites a large proportion of the 
h^j crop. Our reasons for still continmng to doubt the nativity of 
this plant in Ireland will be fonnd fully giyen in the latter portion of 
this Paper. It will suffice here to say that a plant which has quite re- 
cently become e&tablished, with every appearance of a native, in Queens- 
land, Australia, and also near Christchurch, in the South of England> 
may in Ireland have had a similar origin, and therefore cannot any 
longer be cited with confidence as indicating a former connexion between 
the American and Irish Floras. 
From the Kev. S. A. Brenan, the Eev. S. Madden, Mr. John Dong- 
las, Miss E. M. Farmer and others, we have received continual and most 
useful contributions. Besides these sources of private information, we 
have freely drawn upon Seemann's, nowTrimen's, Journal of Botany," 
and availed ourselves of the information given by Br. Sigerson, Dr. 
P. Wright, Mr. S. A. Stewart, Mr. R. Tate, Mr. W. Andrews, Mr. G» 
H. Kinahan, and the late Mr. F. J. Foot in their published papers, 
the titles of which will be fully quoted hereafter. 
In a copy of Threlkeld's Synopsis Stirpium Hibernicamm," 
belonging to the Eoyal Irish Acad-emy, are a few MS. notes left by 
some former owner, from which we have extra€ted those that seemed 
sufficiently important. One of these memoranda supplies a probable 
clue to the author of the list of plants in Harris's Down," whose 
name appears to have been Isaac Butler.* 
Last, but not least, we gratefully acknowledge the kindness of Dr. 
R. Templeton, Deputy Inspector- General of Hospitals, who has most 
liberally favoured us with the loan of the MS. " Catalogue of the Native 
Plants of Ireland," which was drawn up between 1794 and 1810 by 
his father, the eminent naturalist, John Templeton of Belfast. 
In enumerating the plants added to the Irish Flora since 1866, it 
will be convenient to arrange them under the following heads : — 
Of these the last three, printed in italics, have before now been 
recorded as Irish, though in 1866 we did not think that there was 
sufficient authority for their admission as such. 
All eight are well known to occur in Great Britain, but at the time 
when first found in Ireland neither Scirpus parvulus nor Aira uUginosa 
had been gathered for many years.
