this manner he discovered Barbarea stricta, between Sheffield and 
Halifax. To his quick discrimination, also, the British Flora is 
indebted, I believe, for Leersia oryzoides, which, first noticed by him 
in the Henfield Levels, has since been found abundantly at other 
places in Sussex and Hampshire. Another interesting plant, Isnardia 
palustris, was also first noticed by him as a British native in 1827, 
in a pool at Buxtead, Sussex. 
While thus successful and sharpsighted himself, he was, more- 
over, equally skilful in testing the alleged discoveries of others. 
A Westmoreland “ guide,” in the Lake District, had represented that 
he had discovered, in that locality, a habitat for Cypripedium Cal- 
ceolus; but Mr. Borrer, doubting the correctness of the statement, 
was at pains to visit the spot for three years successively, at the 
time of flowering of the plant, and was at length able to expose the 
attempted imposition. 
Zealous and able botanist as he was, Mr. Borrer published scarcely 
anything under his own name or in a separate form. He was, 
however, a constant contributor to science in other ways, and 
especially in the Supplement to ‘English Botany.’ The Lichens 
throughout that work were very generally described by him, as were 
also most of the Salices, Rubi, and Roses, to which genera he had 
paid particular attention; and in the preface to the ‘ British Flora,’ 
Sir W. J. Hooker acknowledges his great obligations to Mr. Borrer, 
more particularly for a complete revision of the genera Myosotis, 
Rosa, and Rubus. 
The only other separate work, as it would seem, under his name, 
and then not alone, was commenced and partially carried out by him, 
in conjunction with Mr. Dawson Turner, in the year 1813, although 
its publication, partly owing to the death and derangement in the 
affairs of the publisher, was delayed till 1839. The work, modestly 
entitled ‘ An Attempt at a History of the British Lichens,’ was even 
then brought out by his coadjutor, Mr. Turner, for private circula- 
tion only, that gentleman’s object being (to quote his words in an in- 
troductory letter to Mr. Borrer), “that it may remain a monument 
of your industry, your ability, and your profound knowledge of the 
family of Lichens.” And the dedication, which is also addressed to 
Mr. Borrer, commences in the following affecting terms :— 
“More than twenty-six years have now gone by, since you and I, 
warm with the hopes of youth, and sanguine in its projects, wrote 
and printed the contents of this little volume. That its progress 
was thus interrupted, and that we stopped in the vestibule of our
