Cycloloma atriplicifolium (Sprene.) Coulter, Mem. Torr. Club, v, 148 (1894); 
Kochia atriplicifolia Spreng. Nacht. Fl. Hall, ii, 35 (1801); Salsola platyphylla Mx. 
Fl. i, 174 (1803). 
Mullen, July 17 and 24; Natick, September 11 (No. 1585). 
Chenopodium leptophyllum (Moyq.) Nutt.; Moq. in DC. Prodr, xiii, pt. ii, 71 
(1849); C. album leptophyllum Moq, in DC. Prodr. loc. cit. 
My specimens have a little broader leaves than usual. Common: Thedford, June 
21; Mullen, July 18; Norway, June 22 (No. 1386). 
No. 1835 is a form of this species that deserves a varietal name perhaps better than 
the next. It has the leaves large, sometimes 5 cm. long and 2.5 em. wide, very thin, 
glabrate above and somewhat hastately lobed at the base. Mullen, July 17; Plum- 
mer Ford, August 22, 
Chenopodium leptophyllum oblongifolium Wats. Proc. Amer. Acad. ix, 95 (1874). 
Scarcely deserving a varietal name. Dry soil: Mullen, July 24 (No, 1836). 
Chenopodium leptophylum subglabrum Wats. Proc. Amer. Acad. ix, 95 (1874). 
This may be a distinct species, at least is a good variety. In its slender peduncles, 
distant flowers, and smooth leaves it resembles somewhat C. boscianum, from which, 
however, it is easily distinguished by its narrow leaves. Norway, June 23; Thed- 
ford, June 27; Plummer Ford, July 3 to 6; Mullen, July 17 and 18 (No, 1351). 
Chenopodium fremontii Wats. Bot. King Surv. 287 (1871). 
This is the same as Nos. 570 and 1734 of Wright’s collection, which constitute a part 
of the material on which Watson based this species. Watson’s own specimens, No. 
973 in the King Survey collection, however, are undeveloped, and have very small 
leaves, and to me they seem to belong to a different species. 
Always growing in shade: Dismal River, June 29; Plummer Ford, August 22; 
Whitman, September 20. Some of the specimens from Plummer Ford are more mealy 
than usual (No. 1450). 
Chenopodium fremontiiincanum Wats. Proc. Amer. Acad, ix, 94 (1874). 
Perhapsalso a good species; apparently found only in prairie-dog towns. Thedford, 
June 19 and 21; September 7 (No. 1394). 
Chenopodium album I.. Sp. Pl. i, 219 (17533. 
The common form was rare. Its place as a weed seems to be taken by C. lepto- 
phyllum. Forks of Dismal River, June 11 (No. 1524). A form with thin leaves was 
collected near the Forks of Dismal River, July 18; Mullen, July 17 (No, 1542). 
cro 
Chenopodium hybridum L. Sp. Pl. i, 219 (1753), 
Not uncommon along Dismal River: Plummer Ford, August 22; Forks of Dismal 
River, July 12 (No. 1525). 
Chenopodium rubrum I.. Sp. Pl. i, 218 (1753), 
Swampy place near a lake, northwest of Whitman, September 20 (No. 1791). A 
low, autumnal form was collected in a dry lake, west of Whitman, September 19 
(No. 1782). 
Corispermum hyssopifolium L. Sp. Pl. i, 4 (1753). 
Not uncommon: Mullen, July 17, September 16; Natick, September 11 (No. 1647). 
Salsoli kali tragus (L.) Moq. in DC. Prodr. xiii, pt. ii, 187 (1869); Salsola tragus 
L. Sp. Pl. ed. 2, i, 822 (1762). 
This weed is rapidly spreading through Nebraska. The railroads, especially througl: 
the cattle cars, seem to be the principal means by which it is distributed. It had 
established itself along the railroad at Thedford, August 28; less fully at Mullen, 
July 24 and September i6. [ found a few specimens even near Plummer Ford, 15 
miles from the railroad, August 22 (No. 1593).
