about the wells was Pyrrocoma subviscosa Greene, and Sisyrin- 

 chium halophilum Greene, both from type locality. Other abun- 

 dant species were Ivesia Kingii and Ranunculus Purshii, On 

 the dry hills just north of the wells a few plants of Eriogonum 

 aridum Greene, also from type locality, were obtained. Dr. 

 Greene's remark of "peculiar to the arid foothills above the 

 Humboldt Wells in eastern Nevada," is a very fitting descrip- 

 tion. The hills are hot and dry and arid, and nothing better 

 can be said of them, except that there is a narrow strip of moist 

 meadow land lying between. Bolelia laeta Greene, also first 

 collected here was not found, but was plentiful in moist low 

 places at Deeth. Speoimens were also found in 1907 at Sparks, 

 near Reno, 350 miles west of the type station. 



The more or less alkaline meadow land along the Hum- 

 boldt at Deeth is the type locality for a number of Dr. Greene's 

 species, but only two of them were ionndi^ Pentstemon praten- 

 sts, a beautiful white flowered species found in moist meadows 

 for many miles along the base of the range, and Chrysothamnus 

 consimilis, plentiful all about the borders of the meadows in 

 moist alkaline places. 



A clover, referred for the present to Trifolium Beckwithii^ 

 was common in one field, comprising at least a third of the hay 

 crop. The stems were very tall and weak for that species, but 

 they had to be tall in order to successfully compete with the 

 timothy and other grasses with which it was growing. This is 

 the plant referred to by Dr. Greene in Pittonia 3: 222, under T. 

 Kingii. T. Harneyense Howell, was also found sending its long 

 and thick fleshy roots deep into the stiff soil, but was not so 

 plentiful here as in the valley below Lamoille, where its pale 

 purple heads thickly dotted the meadows. 



The beautiful annual Castilleja exilis A. Nelson, was found 

 here and there in low moist places, but it seems to be a fairly 

 common plant in northern Nevada, occurring also about Reno. 

 Several asters were found, but none of them answer to the de- 

 scription of Aster exsul, collected there bv Dr. Greene.
