362 THE JOURNAL OF BOTANY 
this year’s Journal, and which, with Diotis and Salsola, were found 
on the island by the Marquis of Blandford in 1798 (see Correspon- 
dence of Sir J. E. Smith, ti. 485). 
Mr. Linton’s book naturally suggests comparison with the Flora 
of Plymouth, a work devoted to a district of the same extent, but we 
do not find in it the numerous and interesting notes on the life- 
history of the species, which raised Mr. Briggs’s work to a level 
above that of a mere local flora. The most important addition to 
our knowledge is the description of a new subspecies of Orchis macu- 
lata, which we transcribe for the benefit of those who may not

We shonld be in a better position to describe the scope of this 
work had the authors favoured us with a preface. We conclude; 
however, that the ‘Systema Englerianum” is that of the great 
Pflanzenfamilien of Engler and Prantl, and that the limits of gener@ 
here adopted are those accepted by the authors of the various mond- 
graphs of which that work is made up. It would appear also that
