CHENOPODIACE^.^ 



Chenopodium album, L. Throughout the United States to the Pacific 

 and northward to Hudson's Bay and Bear Lake. It occurs in the collection 

 in various forms, some of which are beyond doubt indigenous. The ordi- 

 nary tall variety with large acutely-toothed leaves, (a form of Var. hetero- 

 phylhim, Ledeb.,) was only collected in the Truckee Meadows, Ne- 

 vada. (969.) 



Specimens from Blue Spring Valley, Utah, 1° or more high, have the 

 leaves less than 6" long, ovate, rounded or very acute, entire, or the few 

 teeth obtuse or acute ; fruit in numerous dense approximate clusters as large 

 as small peas, with the calyx very strongly keeled, nearly covering the seed ; 

 October. (970.) 



Forms of Ledebour's Var. integrifolium are more frequent, and espe- 

 ciall}! the Var. leptophyllum, Moq., with lance-linear or linear entire leaves, 

 hoary-farinose, the branches of the panicle rather long and loose, the stems 

 low, usually but 1° or often less in height. It has been found from Dakota 

 to New Mexico and westward, by Nuttall, Nicolet, Gordon, Fremont, 

 Wright, and others, and is certainly indigenous, though it appears to run into 

 ordinary mride states of C. album. Carrington Island in Salt Lake, and on 

 the East Humboldt Mountains, Nevada; 4,500 and 9,000 'feet altitude. 

 (971.) Larger specimens, approaching the same form, were collected in 

 Truckee, Regan, and Diamond Valleys, Nevada ; 4-5,500 feet alti- 

 tude. (972.) 



Chenopodium Feemonti. More or less farinose, 6'-3° high, diffusely 

 branched ; leaves oblong, ovate or broadly triangular, 4-15" long, mostly 

 hastate, abruptly attenuate into a slender petiole ; panicle loose and spread- 

 ing with short bractlets ; calyx-lobes carinate-cucullate ; seed horizontal, 

 smooth, and shining. — Collected by Fremont on the North Platte upon his 

 first expedition. Truckee and Monitor Valleys and on the foot-hills and 

 ridges of the East Humboldt Mountains, Nevada ; 4-800 feet altitude ; July, 

 August. (973.) 



Chenopodium hybeidum, L. Foot-hills of the East Humboldt Mount- 

 ains, Nevada, and in the canons of the Wahsatch ; 6-7,000 feet altitude ; 



' The plants of this Order in the collection were mostly examined and the new species named or 

 indicated by Dr, Torrby, hut he is not responsible for the descriptions, nor in some cases for the deter^ 

 minations.
