2 ADDRESS OF THE EDITORS. 
every number, one sheet, or half a sheet at least, of descriptive 
British Botany, with distinct independent pagination, which, 
when completed, will form a portable Flora. A brief view of 
the nature and objects of this part of the ‘ Phytologist,’ or rather 
adjunct to it, will be desirable. The descriptions of the orders 
and genera of our native species will be rather more extended 
than in any existing portable English work of this kind; and the 
diction will be as plain and concise as the subject will admit. 
The orders will be illustrated by a cut of some well known or 
easily recognized plant of the described order. 
The specific descriptions will of course vary in length. Where 
the plant can be easily distinguished from its kindred species, the 
description will be short; where it is otherwise, the deseription. 
will be enlarged. Again, the description will be systematic, 
a. e. the characters of the organs will be arranged according to 
their importance in the economy of vegetation, and invariably de- 
scribed in that order in the families, the genera, and the species. 
The statistics of the plant, also its range and altitudes, will be 
quoted from the Cypetz Brrrannica, with the kind permission 
of the learned author of this valuable work. 
Finally, a glossarial index will be prepared, explanatory of 
every scientific term or phrase, the etymology and explanation 
of every specific, generic, and ordinal term; thus supplying the 
British botanist with a complete apparatus for the identification 
and study of all the phznogamous species occurring in these 
islands. 
From our contributors we solicit articles on the following sub- 
jects. 1. Local botany; and under this head we request infor- 
- mation on the followmg points:—a, the number of species in 
a certain defined district, comprehending the nature of the soil, 
the altitude, and the exposure; 6, the rarer species, with their 
apparent statistics, their range both horizontal and vertical; c, 
the introduced species, or recently observed plants; d, abnor- 
mal or metamorphosed forms, varieties, ete. 2. Papers on the 
flowering of species, the leafing of trees, effects of temperature 
on vegetation, maturation, and decay. 8. On new localities of 
rare plants, or reappearance of plants im localities where they had 
disappeared. 4. Monographs of British genera ; Potamogeton, 
for example. 5. On critical plants—Hieracia, Rubi, Salices, ete.
