the elaboration of distinct portions: thus the work has now 
become a collection of independent Monographs, placed in 
order by a common editor, and reduced to a uniform sys- 
tem of typographical arrangement. "The result is a con- 
siderable, though unequal, improvement as to detail, and the 
only drawback is the occasional omission of a genus, expelled 
from one Order by having been improperly associated with it, 
and not taken up by the author of that one to which it should 
be referred. But these cases are few ; nor are they of so much 
importance in a “ Species ;" for such a work must now be 
much too bulky to dispense with the use of a Genera Plan- 
tarum; where repeated references to anomalous genera slightly 
connected with various orders can more easily be given. In 
a Species Plantarum, the anomalous genera are best placed 
at the end of the classes or large groups to which they 
certainly belong, with a mere reference from those orders to _ 
which they have been or are likely to be assimilated. 
In the two volumes before us, Professor Alphonse De 
Candolle, editor of the whole work, is himself the author of 
the Myrsinacee, Sapotacee, Ebenacee, Apocynacee, Loga- 
niacee, and some other lesser Orders, and has revised his 
father's manuscripts of the Oleacee, Jasminacee, Bignoniaceæ; 
Boraginacee, (in part published), and a few small Orders; 
M. Duby has contributed the Primulacee, M. Decaisne the 
Asclepiadacee, Prof. Grisebach the Gentianacee, M. Choisy 
the Convolvulacee, and Mr. Bentham the Polemoniacee. The 
manuscripts are printed as received from the authors under 
their responsibility, except as to typographical correction. 
(which now, as before, is done with remarkable care) and the 
name of each author appears in the running titles on the top 
of each page. i 
The eighth volume commences with those Corolliflorous 
Orders which have the stamens opposite to the lobes of the 
corolla, and a truly central placentation without dissepiments 
and of these the Lentibulariee are the first. This small order 
is worked up by Alph. De Candolle for this occasion, having 
previously been the subject of a detailed memoir of Auguste
