Pentstemon violaceus Erigeron aphanactis 
In sandy waste places throughout the same belt we find: 
Conanthus aretioides Viola senecta 
Coldenia Nuttallii Lupinus malacophyllus 
- Oenothera caespitosa Eatonella nivea 
- Chylismia scapoidea Anisocoma acaulis 
Nemacladus ramosissimus Abronia crux-maltae 
Gilia nudicaulis Muilla transmontana 
Eriocoma cuspidata Leucocrinum montanum 
In waste places throughout the city Jva axdlaris and Mar- 
rubtum valgare are common plants, while the borders of the 
‘streets are densely covered with Sophia incisa and S. pinnata, 
Bromus maximus, B. rubens, B. racemosus, and B. tectorum 
also occupy considerable areas along embankments, but always 
near the railroad or highways. Hordeum jubatum and Cuscuta 
epithymum are common pests in the alfalfa fields. In a few 
places Elymus triticoides also subsists under very unfavorable 
conditions as to soil and moisture. A plant which may be con- 
sidered rather rare in the valley is Lschscholtzta leptandra. So 
far this plant has been found in the valley only along the rail- 
road track near Verdi in the foothills of the eastern Sierras. 
The writer has found it, however, about fifty miles north of 
Reno in a very remote locality and about twenty-five miles east- 
ward from the Sierra Nevada mountains. It may be considered 
a good Great Basin plant. 
Eschscholtzia micrantha, the same plant as is mentioned in 
the Botany of the Fortieth Parallel as Z. minutzflora, is found 
only at Truckee Pass and points outside the valley north and 
east in the desert country. The following thistles are all found 
within the region but never abundantly: Carduus Nevadensts, 
C. Drummond, C. canescens, C. Anderson. 
Forsellesta Nevadensts occurs in a few scattered localities, 
usually in the low foothills, but the plants are so severely 
browsed on by stock that it was only recently that the writer 
was able to secure a flowering specimen which had drifted into
