WILD HELIOTROPE. 

 Phacelia tanacetifolia. Bentk. 



Erect, one to three feet high, roughish-hirsute or hispid; leaves nine to seventeen, 

 divided into linear or oblong-linear once or twice pinnately-parted or cleft divisions, all 

 sessile or nearly so; the lobes small and mostly linear-oblong ; spikes cymosely clustered, 

 at length elongated ; the very short pedicels ascending or erect ; corolla light violet or 

 bluish ; stamens and style usually very much exserted ; calyx-lobes linear or linear 

 spatulate, not twice the length of the oval or oblong-oval capsule (Brewer & Watson). 



TIDY-TIPS. 



Gaillardia aristata. Pursh. 



Perennial, a span to a foot or more high ; lowest leaves spatulate or oblanceolate, 

 sometimes pinnatifid, tapering into petioles ; the upper sessile and often entire ; bristles 

 on the receptacle slender, much longer than the akenes, sometimes almost as long as the 

 corolla ; rays ten to eighteen, an inch or more in length, yellow, sometimes tinged with 

 purple at the very base. 



Plains and open ground, common through Oregon, extending to the Saskatchewan 

 region. 



SNOW PLANT. 



Sar codes sanguined. Torrey. 



A stout, fleshy herb, a span or two in height, of a bright red color, more or less 

 glandular-pubescent, thickly clothed, at least up to the raceme, with firm, fleshy scales ; 

 the lower ones ovate and closely imbricated, the upper gradually more scattered, narrower, 

 and passing into the linear bracts, which mostly exceed the flowers, their margins 

 glandular-ciliate ; pedicels erect, at least the upper ones short ; corolla half an inch long, 

 rather fleshy, glabrous. 



In coniferous forests, especially those of Sequoia and Abies, through the Sierra 

 Nevada, from four thousand to nine thousand feet, shooting forth and flowering as soon 

 as the snow melts away (Brewer & Watson).
