System of all the Genera and Species. The second part contains the 
Jussieuan or Natural Arrangement of all the Genera, in such a way 
that a direct reference may be had from the Artificial System to the 
second arrangement, and again from the second to the first, without 
repetition of the species or any details connected with them.” It is 
clear however that preference is given to the Artificial or Linnean 
. System over the Natural Arrangement ; though we feel confident that, 
in the present day, the latter would have been preferred. It was not 
so perhaps when the first edition was prepared, and there were rea- 
sons, probably of economy, for republishing that exactly in the same 
| form, and giving the additional matter in two “additional supple- 
= . ments;” the first (in 139 pages) including all the plants originating 
: in, or introduced into, Britain, between the first publication of the 
work in 1829 and January 1840, by W. H. Baxter, jun., under the 
- direction of J. C. Loudon, and revised by George Don; the second (in 
263 pages) including all plants so introduced between 1840 and 
March 1855, prepared by George Don, under the direction of Mrs. 
: J. C. Loudon, assisted by Mr. David Wooster: the whole is concluded 
- by a full Index of the systematic and English names, and the English 
. and systematic synonyms in common use. 
- We are far from saying that the generic characters are in general 
sufficiently full or satisfactory to enable “ an English reader," by which 
. it is to be understood one little if at all familiar with Botany, “to dis- 
cover the name of any plant he may find in flower,” but it will often 
_ be a great help to him; and with due study and application, aided by 
. the numerous figures and the index of popular names, a tyro may 
learn a great deal. It is of course, we need not say, a book of great 
value to the horticulturist, for it notices all the plants that have been, 
down to the present period, cultivated in our gardens ; to the student 
of British botany, for the plants of our country are figured and de- 
scribed ; and we now come to give the book its highest character, viz. 
it is the only portable botanical work that can be useful to a traveller 
in foreign countries, and we have repeatedly recommended it as a com- 
panion to such wanderers, to whom it has proved really useful, and we 
have on that account regretted it has been so long out of print. But 
here we would beg that we may not be misunderstood. It is not meant 
it ean take the place of the ‘Flora of New Zealand’ with the 
tor to, or resident in, New Zealand; but, seeing that ¢had is literally
