396 Piper : Noteworthy Northwestern Plants 



v Erigeron curvifolius n. n. 



Chrysopsis hirtella DC. Prodr. 5 : 327. 1836. 



Perennial with several or numerous branches from a woody 

 caudex, 5—10 cm. high : root straight, simple : leaves not densely 

 crowded, linear, entire, acute, sessile, more or less curved, 1.5—3 

 cm. long, 1-2 mm. wide, hirtellous with white hairs, the midrib 

 broadened and whitish toward the base : flowering stems numer- 

 ous, slender, appressed hirsute, scarcely exceeding the leaves, 

 monocephalous, or rarely with a second smaller head : heads 

 about 1 cm. high: involucre of 25— 30 linear acuminate hispidulous 

 bracts, all at length reflexed : rays 30-40, pale yellow, linear, 1 

 cm. long : achenes appressed hirsutulous ; outer pappus of very 

 short setae ; inner nearly equaling the floret, which with the 

 akene is 4 mm. long : receptacle with the alveoli wanting or very 

 obscure, minute setae appearing in their places especially near the 

 margin. 



Readily distinguished from E. Chrysopsidis Gray by the much 



1 



smaller heads and florets, very different leaves and by the recep- 

 tacle not being alveolate. 



It is a plant of the dry sandy plains of the Columbia and its 

 habitat taken in connection with the linear leaves and peculiar re- 

 ceptacle renders it nearly certain that this plant, and not the sub- 

 alpine Erigeron Chrysopsidis Gray, is the Chrysopsis hirtella of 

 De Candolle.

* Pentstemon Gairdneri hians var. nov. 



Shrubby and decumbent below, the flowering shoots erect or 

 nearly so, 2-3 dm. high, cinereous puberulent, or above glandu- 

 lar : leaves rather numerous, alternate, linear or linear-spatulate, 

 sessile, acutish, revolute, more or less curved, ascending, 2-^ cm. 

 long, 2 mm. wide : flowers 10-20, racemose or somewhat panicu- 

 late, rather strict ; bracts lanceolate, acuminate, about 1 cm. long : 

 calyx 1 cm. long, the lobes ovate, acuminate, subequal, free quite 

 to the base, not equaling the corolla tube : corolla red, minutely 

 glandular, 2.5 cm. long, tubular-funnelform, broadly dilated in the 

 naked throat, bilabiate, the prominent lobes broadly rounded, sub-
