‚Mr. Hookzr’s Observations on Andrea. 891 
upon most of the high mountains, it seems to be not uncommon, 
and is even plentiful upon Ben Lawers, Ben-y-more, and Ben 
Nevis, but always upon the rocky summits, and even there of 
far less frequent occurrence than A. rupestris or Rothii. Mr. 
Turner has also received Irish specimens, gathered both by Mr. 
Templeton and Mr. Mackay.

* Linnzus’s description, in the second edition of Flora Suecica more particularly, 
and in the Species Plantarum, of this plant seems best to accord with A. Rothii; but 
his own specimens in the Linnzan Herbarium prove this to be the plant he intended, 
unless, as is most probable, he confounded the two.
