ADDITIONAL LIST. 471 
the cloak of species. Further consideration of those supposed 
species led their inventor to abandon them altogether, even as 
varieties seemingly. Instead of making haste to encumber our 
lists with false species, it would have been a wiser course first to 
ascertain their validity, and then to name and describe them only 
if warranted in doing so. Now, by the course taken, other 
botanists are left in this ambiguous position:—Are we to treat 
those two specific names simply us synonyms with tetrandrum, or 
are we to deal with them as representing segregate plants of a 
grade below species? Surely there must have been, and so still 
must be, some differences to warrant a specific severance of them 
from the ordinary C. tetrandrum ? Again, the Ranunculus flori- 
bundus of the same botanist, the Hieracium nudicaule of Edmond- 
ston, Pow polynoda of Parnell, with various other names in 
printed books, may optionally represent either word-alone species 
or very ambiguous segregates. 
The plants to come within the following List are thus seen 
to be so very miscellaneous in kind and in their claims to notice, 
that no precise plan for treating their distribution can be made 
successfully applicable to them; while they are so numerous that 
strict brevity is indispensable. As a rule, occasionally to be 
departed from, only three lines can be allowed to each plant; and 
the first of the three will be required for the name, which ought 
to stand alone for the sake of typographical clearness. The second 
line will enumerate the provinces, as was done in the Synopsis; 
aud in cases where the provincial nos. are very few, the full series 
of intermediate blanks will be omitted; a little space being so 
gained for a brief remark, the citation of an authority, or name 
of a county, etc. The character of the plant in Britain will be 
indicated in the third line, by one of the terms before explained ; 
in the case of ‘Segregates’ the No. of the ‘ Aggregate,’ under 
which they fall in the Synopsis, is substituted instead of the 
categorical term. Many of the Alien plants and others were 
commented upon at some length in the original Cybele Britannica ; 
and as they cannot be so treated within the much less space
