In the succeeding order, Amarantus is restored to its old 
limits, including not only Euxol lus and Mengia, but mt Amblo-

subtribe. The old difficulty of limiting Chenopodium and Blitum 
is effectually ap Saar rida by reducing the latter to one of the five 
sections of the former. TZeloays is of course a Chenopodium, and 
Obione is not cistinigaisliel even sectionally from Atriplex. The 
important distinction between the plane-appressed fruactiferous 
bracts of Atriplex and its allies, and the conduplication and union 
of these bracts in Swckleya and the three pase associated with 
it upon the establishment of the latter genus, is not as prominently 
exhibited as it would have been by the adoption: of the subtribe 
Eurotiee. 
Batis, with a single species, stands for an order Batidec. 
Polygonacee are marked by the introdnction, between the 
Eriogonee and the Hupolygonee, of a tribe Kenigice, which 
besides the typical genus and its evident relative Pterostegia, is 
made to include Lastarriwa, ape ea nee and ollisteria, whose 
affinities are more Eriogoneous. eren atson’s natural arrange- 
ment of er gon is adopted ; but Vaarcasiis is kept distinct 
from Choriza 
e Piperaces include the Saururee, and Anemopsis is reduced 
to Houttynia 
The great ‘order Laurinee - peorene ty come: Pas all Ni 
concerns us is, that our Californian Laurel i oved 
Tetranthera or rather Litsea yas ., and one of ‘the re wo Bape 
names which Nuttall applied to it is used for this at length well 
ute erized genus, viz: Umbellularia,—not a good name, but

In Santalacee, the still piggy abr! known genus Darbya is 
well removed from Comandra, to which DeCandolle referred it: 
whether it is here rightly joined to Pucldaes can be known only 
when female ae or fruit are discovered. These are special 
desiderata. The plant (a low shrub) is oe be sought between 
Lincolnton, North Carolina, and Macon in Georgia! 
e immense order Lup horbiacecee has been studied anew, the 
great labors of Baillon and of J. Miller duly weighed, and the 
result is that six tribes are pic under simple characters, and 
the ample sixth tribe, Crotonea, is divided into eight subtribes. 
The views adopted have been pone by Mr, Bentham in a 
memoir, some notice of which has appeared in this Journal. The 
genera nearly reach 200, and there are over 3000 described
