to be found growing in Mackay’s exact localities. His record 
of Poa alpina is especially interesting, as furnishing 2 good 
illustration of how tenaciously a native plant will cling even 
to a most restricted station, in this case an exposed surface of 
rock a few square feet in extent, where it has now been known 
for well over one hundred years : it does not appear to occur 
anywhere else in the south of Ireland. 
The second of Mackay’s works, his “Catalogue of the 
Indigenous Plants found in Ireland,” was published 19 years 
later in the Trans. of the Roy. Irish Acad. 1825, and adds 12 
more to the Kerry total; of these Arabis ciliata (found by 
James Drummond between 1810 and 1820), Hypericum 
calycinum, Galium boreale, and Utricularia intermedia are best 
worth mention. 
Finally in his Flora Hibernica, an octavo vol. published in 
Dublin in 1836, Mackay contributes another five, including 
Carex filiformis (found by James Drummond), and Lycopodium 
alpinum, bringing his total additions to the county flora up 
to 61. Two or three of these records were for some common 
plants found by Dr. THOMAS TAYLOR (d. 1848), best known 
for his important contributions to cryptogamic botany. 
About this time also, two visitors to Killarney put on record 
for the first time a few of the more common members of the 
Kerry flora ; four of these are found in “ Illustrations of the 
Scenery of Killarney, &c.,” a handsome quarto vol. published 
in London 1806, by Isaac Weld ; and two more in George N 
Smith’s “ Killarney and the surrounding Scenery,” published in 
London 1822. An isolated Kerry record appears in Hooker’s Brit. 
Flor. Ed. I. 1830, where Hymenophyllum Wilsoni is described, 
while the 2nd Ed. 1831 contains the first description of the 
Killarney Equisetum Wilsoni, both being from plants gathered 
by William Wilson. Another record occurs in the Supplement 
to Smith’s Znglish Botany 1841, where Dr. Taylor is credited 
with the discovery of Potamogeton prelongus. 
The Irish Flora which appeared in 1833, three years before 
Mackay published his Flora Hibernica, is chiefly remarkable 
as being the first descriptive list of the flowering plants in 
Ireland. The authorship of this book is usually attributed to 
Miss KATHERINE BAILEY (b. 1811—d. 1886); afterwards 
Lady Kane. The Kerry localities it contains are almost all 
taken from the earlier works of Wade and Mackay, the Lady 
Fern being the only plant which does not appear to have been 
elsewhere recorded. 
Ten years later Mr. Ss. P. WOODWARD (b. 1821—d. 1865), 
an English botanist, paid a visit to Ireland, and his ‘“‘ Notes of
