Chenopodece. — In the Flora Altaica, a new arrangement is given by M. C. A. 

 Meyer of the plants of this natural order found in the Altai ; and as this part of 

 the world contains almost all the genera of the order found elsewhere, the follow- 

 ing view, we trust, is not without importance.

Such parts of this system as are taken from the structure, we will allow to be 

 philosophical, although too minute for the oommon botanist ; but upon the ver- 

 tical or horizontal position of the seed, we feel inclined to put less value. Thus 

 several closely allied species of Chenopodium are almost only distinguishable by 

 the position of the seed ; but, according to this arrangement, they must be placed 

 in different genera. C. carinatum, Pumilio, Bonus-henricus, and C. rubrunij 

 are thus thrust into Blitum, of which the fleshy calyx is now to form no part of 

 the character. Nor do we much admire the distance at which Atriplex is placed 

 from Chenopodium. 



Mcehringia Some specimens of M. mucosa have been found to have five 



sepals, ten stamens, three styles, and a capsule with six valves ; and therefore to 

 belong to the genus Arenaria, as much as Tormentilla does to Potentilla. If 

 retained as a separate genus notwithstanding this, M. Koch wishes to unite to it 

 A.trinervis. M. F. Meyer has already proved that A. bavarica only differs 

 from M. mucosa by the somewhat thicker leaves, and perhaps M. sedoides is, on 

 the other hand, identical with A. bavarica. 



Sibbaldia From this, as a genus, Bunge has separated the second section of 



De CandoUe, under the name of Chamcerrhodos. The common iS'. procumbens, 

 however, in cultivation, puts on a very different appearance from what it exhibit^
