great knowledge, and his very extended opportunities, we may reason- 
ably look for such an extended work from his pen. We hope that the 
time is not distant when we may receive it.

We have here the first instalment of a Manual Flora of the environs of 
the town of Hanover, conscientiously executed, and intended for the use 
of beginners, amateurs, and schools. When completed, we may return to 
the work, and will merely remark that the present number comprises the 
Ferns, Monocotyledons, Gymnosperms, Amentacee, and Juglandacee. 
Since Ehrhart, a pupil of Linnæus, took up his abode at Herrenhausen, 
and published his * Beiträge,’ there has not been a local botanist of 
eminence at Hanover; and since that time science had made such 
rapid strides, that much remains to be done before the botany of this 
particular locality is brought up to our present state of knowledge. 
Dr. von Holle divides and arranges the Phanerogamic plants in 4 
manner slightly differing from that adopted by Lange and Will- 
komm. His primary divisions are Gymnosperms and Angiosperms, 
the latter including, not only all Exogens (with the exception of 
Conifere), but also the Endogens. By this arrangement, the Gymno- 
sperms are placed between the higher Cryptogams and the Endogens. 
Endlicher (‘Genera Plantarum’) could not make up his mind to re- 
move the Cycads from the neighbourhood of the Ferns ; and by adopt- 
ing Dr. von Holle’s arrangement they would be retained in that place, 
associated with the true Conifers. We do not wish to argue in favour 
of this view, but may remark that Welwitschia might be regarded as 
much a transition from Gymnosperms to Endogens, than the Cycads 
from Gymnosperms to Cryptogams. 
The little pamphlet, entitled * Farnflora der Gegend von Hannover,”
