extensive, but it includes several plants of extreme interest. “ It 
consists," the author says, “of about 100 species, to which might be 
added, if they could be accurately determined, many other plants, 
chiefly Trees, slightly mentioned in the interesting narrative which is 
about to appear, and to which the present account will form an appen- 
dix. I may also observe, in reference to the limited number of species, 
that Capt. Sturt and his companion, Mr. Brown, seem to have collected 
chiefly those plants that appeared to them new or striking, and of which 
the collection contains a considerable proportion. In regard, too, to 
such forms as appear to constitute genera hitherto undescribed, it 
greatly exceeds the much more extensive Herbarium collected by Sir 
Thomas Mitchell; in which the only two plants proposed as in this 
respect new, belong to genera already well established, namely, 
Delabechia to Brachychiton, and Linschotenia to Dampiera.” 
. In this valuable contribution to the Flora of the Southern Interior of 
Australia, we have, among other novelties, Blennodia, a new Cruciferous 
genus, allied to Matthiola: Sturtia, near Gossypium and Senra : Tribulo- 
pis, allied to Tribulus: Clidanthera, Pentadynamis, and Petalostylis, among 
Leguminose : Podocoma (Composite), and Leichardtia (Asclepiadea). 
In the brief space of twenty-nine pages the learned author has given 
a great deal of valuable information bearing on genera and species not 
described in this work. He estimates the number of Australian species 
as not exceeding, but rather falling short of, 7,000.

In our last number we announced the appearance of the first; part of 
this new work of Dr. Walper's, and the nature of it was noticed. It 
included families (arranged according to De Candolle's Prodromus) ex- 
tending as far as Celastrinee. The present, or second fasciculus of the 
first volume, closes with the commencement of the Composite. The 
addition of species in the short time that has elapsed since the appear- 
ance of the “ Repertorium " of the same author, is quite remarkable, 
and exhibits clearly the progressing state of the science. Of Astragalus 
alone there are thirty-seven species, and we could add to them consi- 
derably in new species lately named by Boissier, in our own Herbarium, 
and which he is about to publish in the somnia of his valuable
