ACCENTUATIONS AND INDICATIONS. 
All the botanic names throughout the Work are accented, and have their origin indicated, as in 
the Hortus Britannicus and the Gardeners Magazine. The vowels which are sounded short are 
marked with an acute accent, thus (’), as A’ceras ; and those which are sounded long are marked 
with a grave accent, thus (‘), as A‘brus. The origin of each name is indicated thus: if the name 
has been applied to a plant by the ancients, the first letter is n Italic, as Pinus; if it is comme 
morative of some individual, the letters additional to the name are in Italic, as Banksia, Lam- 
bertidna, Douglasi?; and if an aboriginal name has been adopted, or if the name is of uncertain 
derivation, the whole word is in Italic, as, A#léntus, Caragdna, &c. Where the name would otherwise 
be in Italic, as in the case of synonymes, headings to paragraphs, &c., these distinctions are, of 
course, reversed, as Pizus, Banksia, Ailantus. All the other scientific names, generic or specific, are 
composed from the Greek or Latin, except a very few which are taken from places: as Araucaria, 
from the couutry of the Araucanians ; Quércus gramuntia, from the estate of Grammont, &c.
