II. ARRANGEMENT OF THE TEXT, AND ABBREVIATIONS 
USED IN THE PRESENT WORK. 
In the following pages the name of each Family or Order (for the two 
words may be indiscriminately used) is given in Latin and in English. 
The English name is always in two words, exclusive of the particle. 
Where the first word is not the name ofa genus also, it may be used alone 
to designate the family by putting it in the plural, as Cruczfers for the 
Crucifer family, Waterlilies for the Waterlily family. Where however it 
is also the name of a genus, and it is wished to designate the family by 
a single word, in crder to avoid confusion, either the Latin name must be 
taken, or it must be Anglicised by some of the modes which have been 
proposed, such as substituting the terminations tds for zde@, and anths or 
ads for ace@, as: Orchids for Orchidaceae, Rununculanths or Ranunculads 
for Ranunculaceae. 
After the name of the family, the first paragraph, in large type, is the 
character of the family; the second, in ordinary type, contains remarks on 
its geographical distribution and affinities. 
This is followed, in small type, by the analytical key of the British genera 
belonging to the Order, as above explained, (p. lii, par. 245); and short 
memoranda are occasionally subjoined on commonly cultivated plants be- 
longing to exotic genera.
