Henderson : New Plants from the Northwest 351 



In aspect the plant resembles small forms of N. pliacclioidcs 

 Nutt., but easily separable from that species in opposite leaves, 

 smaller stature, vari-colored corolla, and deeply pitted seeds, to 

 say nothing of its far different range. From N. aurita it differs in 

 absence of winged petioles and clasping base of leaves, less divi- 

 sions to the leaves, and color of flowers. From N. racemosa it 

 differs in not having a racemose inflorescence and in larger flowers. 



No. 3082. Growing in warm, loose soil under Pinus pon- 

 derosa, Salmon River hill, beyond Florence, Idaho County, July 

 1, 1895. 



I take pleasure in dedicating this species to my young friend 

 and companion of my 1895 trip, Charles Kirtley, of Salmon, 

 Idaho.

s Phacelia minutissima 



Annual, 2-6 cm. in height, hirsutely pubescent, glandular 

 above, branching from the base, erect : leaves narrowly oblanceo- 

 late to spatulate, the base narrowed into a slender petiole, the 

 blade entire or rarely slightly denticulate : flowers not numerous, 

 shortly pedicelled : sepals spathulate-linear, 2-4 mm. long, 

 moderately l5r far surpassing the small, bluish-white, oblong- 

 campanulate corolla : the appendages of the latter not long, 

 somewhat v-shaped at the base of the filament : anthers not small 

 for size of flower, on filaments rather stout and one half to two 

 thirds the length of the corolla : capsule rather large, ovate, 

 acute: seeds l—1. 5 mm. in length, somewhat angled by pressure, 

 oval-oblong, marked with a delicate net-work of roundish figures. 



Very near to P. saxicola Gray, but it differs from that species 

 in seeds being 3 or 4 times larger, (those of P. saxicola being only 

 0.35 mm. in diameter), not round but widely oblong and with much 

 smaller reticulations, in shorter corolla, larger anthers on shorter 

 thicker filaments, in appendages not so "linear" but -shorter and 

 making a much more noticeable angle at their juncture with the 

 stamen base. 



No. 3386. Dry, gravelly or rocky ground, at 8000 feet ele- 

 vation, Soldier Mountain, Blaine County, July 16, 1895. 



Type in the Washington Herbarium, co-types in the Idaho and 

 Gray herbaria.
