tinguishable by more than one character, existing either in 
the parts of fructification or in habit, notwithstanding which 
I have not ventured to separate them into distinct genera, 
as I probably should have done, had I been acquainted with 
fewer species; but have given to each section a proper name, 
a practice that may perhaps be advantageously adopted in 
all large genera, where they are thus capable of natural 
subdivision. It must be unnecessary to observe that proper 
names can in this manner be given only where the sections 
are perfectly natural, and not in those cases where genera 
have been subdivided from single characters, and those too 
of but little importance, as in Thunberg’s division of Pro- 
TEA, from the form and division of the leaves, to which may 
be opposed the masterly subdivision of the same genus given 
by Linnzeus in the Mantissa, whose sections, though appa- 
rently depending upon single characters, are evidently 
formed from a contemplation of the whole structure, as far 
as it was then understood; and it is remarkable that, with 
the exception of the first species, with whose real structure 
he was necessarily unacquainted, the rest are arranged, and 
even divided into sections, in most cases corresponding with 
the genera proposed in the present way.” 
Bucifolia falls within the division distinguished by cori- 
aceous follicles surmounted by the entire style with its 
depressed stigma, and by oval seeds which are either very 
shallowly bordered all round or very shortly winged at the 
top; and within the subdivision entitled Errosryuis, con~ 
taining those species where the leaves are all entire, flowers 
fascicled and subumbellate; pistil woolly and stalked, and 
the follicle without ribs. Among these it is specifically cha- 
racterized by elliptical leaves dotted and rough above, 
cinereous underneath, from the effect of a close-pressed 
cottony fur, and by an orbicular stigma that is scarcely 
equal to its recurved appendage at the top. 
Our page will not admit of the version of the definition of 
the genus by Mr. Brown.
