t 208, and V. Ruppii, All., arc only modifications of one species. 

 The most certain characters in this genus will be found in the spurs 

 to the anthers. In the Chcnopodiacccc Meyer's arrangement has been 

 adopted, by which several true species of Chenopodium are referred 

 to Blitutn. C. potyspermum and acutifolium are combined, but C. 

 vivid c is kept distinct from C. album ; C. rhomb if olium, Miihl., which 

 i - tin.' urbicum of Eng. Bot., is separated from the true urbicum of Lin- 

 na?us, notwithstanding the observation of Koch, that they proved to be 

 only varieties by repeated culture. Our author's Blitum botryoides 

 does not appear to be the same as C. botryoides, Sm., for he says, 



" caule erecto racemis subaphyllis," but Smith describes the 



stems as "spreading or prostrate," and the spikes leafy. In Atriplcx 

 the names have been remarkably transposed, but the descriptions 

 are so good as clearly to point out what plants are intended ; A. an- 

 gust if alia is probably a form of A. erecta, Sm., which appears to be 

 far from a rare plant in this country ; A. patula is rosea ; A. latifolia 

 is the true patula of Linnaeus and Smith, and A. longipes is probably 

 our angustifolia, the only doubtful point being that he describes the 

 fruit-bearing calyces as " longe pedunculatis." Statice rariflora, 

 given as a new species, appears to be our &. spat hula t a ; S. limonium 

 (jbahusiensis) Fries Mantiss. p. 10, is referred, on the authority of a 

 specimen, to this plant. A new Juncus is introduced between con- 

 glomeratus and effusus, under the name of "J. subuliforus, anthela 

 supra decomposita laxa ramis exterioribus reliquos multum superan- 

 tibus anthelam minorem gerentibus, caps, obovata truncatula, stylo 

 mammillae elevatse insidente." We think it probable that all three 

 will ultimately be combined. The genus Polygonum is divided ; 

 Centinodium (P. aviculare), Tinaria (P. convolvulus and dumetorum) 

 and Fagopyrum (P. fagopyrum and tataricum) being separated from 

 it. The latter of these we hold to be a good genus, the others only 

 sections of Polygonum. In Ranunculus, Smith's aquatilis is divided 

 into aquatilis, circinatus and fluitans, three plants distinguished by 

 well-marked and permanent characters, and now recognised by al- 

 most ever)'' continental botanist, although not as yet adopted in this 

 country. Platanthera solstitialis is H. fornicata, Bab., P. bi/olia, 

 Reich., f. 1143. To this he refers Sven. Bot., t. 314, which is the 

 true 0. bifolia, Linn. 



We have gone somewhat into detail in reviewing this work, 

 for the purpose of drawing the attention of English botanists to the 

 local Floras of the continent, many of which are of great value to the 

 descriptive botanist. We purpose noticing some of the others in 

 future numbers.
