out a distinct perception of the exact na- 
no one can hope to apply it to practical 
purposes with any probability of success. 
These considerations originally led to 
y ‘ Outlines of the 
principles of Organic and Physiological 
Botany depend, were stated as briefly as 
the nature of the subject would permit. 
The success with which this little book 
was received, and its recognized utility to 
udents, whatever its defects. may have 
been, induced me to attempt the far more 
difficult task of reducing the definitions 
employed in the higher part of Systematic 
Botany to their simplest form, and to show 
that the impediments which accompany 
_ this branch of the science are susceptible 
-~ Of being very materially diminished by a 
~ careful and extensive kind of analysis. The 
- * Nizus Plantarum” was written with the 
. view of putting to the test the possibility of 
executing such a plan; and it has been ex- 
tremely satisfactory to me to find that this 
work also, although, in many respects, to- 
tally unsuited to the use of students, has 
nevertheless been, in many cases, em- 
ployed by them with singular advantage. 
“As both the * Outlines of First Prin- 
 iples' and the * Nirus' are out of print, 
I have determined to combine them into 
one work,—a sort of Botanical Note-Book, 
—wherein all the principal topies which 
_ the teachers of Botany either do, or ought 
to, introduce into their lectures, are ar- 
ranged methodically. The student will na- 
turally look to his instructor for explana- 
: tions and illustrations of the work, and for 
fhe exposition, in detail, of those points 
Which in his Note-Book are merely ad- 
verted to.

the language of Botanists in some respects, 
by carrying out their own principles to 
their full extent; thus securing a more 
uniform kind of nomenclature, and ex- 
pressing the value of the names of the 
Classes, Orders, &c., in all cases by the 
manner of their termination.” 
It is stated in the Botanical Magazine, 
folio, 3234, regarding the very pretty An- 
thyllis Webbiana, that it was introduced 
by Mr. Webb, “from Teneriffe: this is 
a mistake, and we have the authority of 
Mr. Webb himself for stating, that he ga- 
thered the seeds, in 1827, on rocks near 
the summit of Sierra Tejada, a chain of 
mountains running almost parallel with the 
Sierra Nevada, near Alhama, in the king- 
dom of Grenada. It was growing in com- 
pany with Cerasus prostrata, and many 
other interesting plants. The same accom- 
plished Naturalist observes that the An- 
thyllis found by Bory de St. Vincent, in 
Teneriffe, is certainly only A. vulneraria, 
as no other species of the genus exists 
there. 
We are much gratified to find that M. 
Du Rieux, a French Botanist, to whom 
Mérat dedicated a Spanish Genus, (which 
however, had already been described by 
agasca, under the name of Lafuentea,) 
has been herborizing in Spain, and ex- 
ploring the vegetable productions on both 
sides of the Austrian and Galician range. 
He has accomplished his journey success- 
fully, though not without danger. An aged 
Botanist, named Perey, who was the un- 
su uccessful competitor with Ortega for the 
do, to which the civil governor was about 
to consign him. His Collection amounts 
to about three hundred and sixty species. 
The country visited is, perhaps, not rich 
in number of species; but there cannot be 
a doubt of there being many highly inter- 
esting plants. We hail with delight any 
attempt to make us better acquainted with - 
Spanish Botany: for it is that country, 
which, of all Europe, is the least known to
