CHENOPODEjE. 



372. Chenopodium subspicatum, JYutt. gen. i. p. 199. 

 Saline plains of the Canadian. 



Obs. Annual ; stem branched, scarcely a foot high, re- 

 markably quadrangular. 



373. C. hybridum, (3 7 simplex ; caule simplici, 5-angu- 

 lare ; foliis ovatis, subcordatis, grosse repando-dentatis; spica 

 simplici, terminali, nuda. 



Hab. Near Council Bluff, on the Missouri. 



Obs. Annual ; stem quite simple, smooth ; leaves green 

 on both sides ; spike solitar}', terminal ; glomerules approxi- 

 mate. Perhaps a new species. 



374. C. maritimum, L. ? C. caule ramoso, glabro; foliis 

 linearibus, semi-cylindricis ? succulentis, integerrimis, mucro- 

 natis ; floribus axillaribus, pentandris. 



Hab. Upper part of the Canadian. 



Obs. Whole plant very smooth and free from furfuraceous 

 scales, turning black in drying. The specimen was with- 

 out fruit. 



375. Kochia dentata, Willd. hort. berol. i. t. 2S. 

 Purshjl. i. p. 206. On the Platte.

 ceding. 



377. Salsola prostrata, Pursh fl. i. p. 197. With the 

 preceding. 



Obs. This is considered by Nuttall as a mere variety of 

 Chenopodium maritimum, L. and indeed it scarcely appears 

 to differ. It is, however, very distinct in general appearance, 

 from our variety described above, which it is very probable 

 will hereafter prove to be a separate species.

 gonum canescens, Pursh jl. i. p. 370. Near the Pawnee
