Hooker doubts its identity with the plant so named by Will- 
denow and Linnaeus.) 
This beautiful species is one of the many interesting disco- 
veries of the acute and interprising Mr Thomas Drummond, 
who first met with it on the banks of the Esk and Isla, and 
where it has subsequently been gathered by Prof. Balfour , 
&c. In Canlochen Glen, a little distance above the shieling, 
it was picked by Prof Balfour , and I there found it in July 
1846, but of course without catkins as these appear in April. 
E. arvense and sylvaticum were associated with it in this lo- 
cality, from both of which it was evidently distinct at a glance. 
It has been also found in woods near Forfar by Dr Greville . 
Sir W. J. Hooker named the plant in compliment to Mr 
Drummond, and no Scotchman will care to see such a well- 
merited honour thrown into the shade , especially as there is 
a shade of doubt about the continental plant being the same 
as ours. 
Mr Drummond was perhaps the most enthusiastic practi- 
cal botanist that Britain has produced, and with this county 
especially his name will ever be honourably associated. In 
the little Elysian botanic garden of “ Dove-hill,” at Forfar, 
he was successor to Mr G. Don, and, while there, published 
his Musci Scotici, a volume of specimens probably unequalled 
by any similar publication in this country. His researches 
in his native county were attended with the greatest success, 
especially among the cryptogamic tribes, and one beautiful 
moss, Orthotrichum Drummondii , has been dedicated to him 
as a testimony of the value of his labours in that department. 
The frequent record of his name in the pages of the British 
Flora , in connection with some of our rarest plants, affords 
ample proof of his zeal, and the valuable results of its appli-
