30 ERYTHEA. 



in many cases a single oil tube is present hi each lateral rib and not 

 rarely one occurs iu all the ribs; sometimes 2-3 rudimentary tubes 

 are present in the intervals, and in very rare cases 2-6 occur on the 

 commisural side ; seed face plane. 



Very common in moist rocky places on the Palouse Hills, Whit- 

 man County, Washington, blooming in April or earlier and matur- 

 ing its fruit by June. The earliest spring flower in the region and 

 locally called "Pepper and Salt," in allusion to the color of its 

 flowers. This plant has been referred to P. Hendersoni C & R., 

 P. Watsoni C & R., and P. farinosum Gey., with none of which it 

 agrees. It is nearest P. farinosum, but has the puberulent fruit of 

 P. Watsoni. 



Aster Jessicae. Stems in large clusters, stout, erect, 1 to 1^ 

 metres high, branched toward the summit, leafy to the top, the 

 whole plant cinereous-pubescent, but not glandular, with short, 

 curved hairs ; leaves thickish, reticulate veined, the radical oblong, 

 tapering to both ends, acute, entire, or rarely with one or two 

 appressed teeth, 5-10 cm. long, on margined petioles as long or 

 longer; cauline oblongdanceolate, entire, acute, sessile or partly 

 clasping (but not auriculate) by a contracted base, the larger 10-15 

 cm. long : panicle loose and narrow, racemose in form ; heads 2-3 

 cm. in diameter, single or in clusters of two or three, terminating 

 stout ascending leafy branches : involucre of about three rows of 

 broadly lanceolate acutish scales, herbaceous or the inner scarious 

 at base; all becoming somewhat scarious in age ; not rarely some of 

 the outer bracts become foliaceous ; rays 20-50, pale violet, about 

 1 cm. long, 2 mm. wide : akenes scabrous hispid ; pappus dirty 

 whitish. 



Along the Palouse River at Pullman, Washington, blooming in 

 August and September. Distributed by me under No. 1604 as Aster 

 integrifolius Nutt., to which it bears no resemblance. Apparently 

 it is nearest A. Hendersoni Fernald. 



Gilia hispida. Annual, prostrate, 5-15 cm. in diameter, hispid 

 throughout with white hairs; stems usually purplish, branched from 

 the base in a falsely dichotomous manner, the branches curving 

 inward in age; leaves all alternate, spatulate-lanceolate, acutish 

 or the earliest truly spatulate and obtuse, 10-20 mm. long, all 

 tapering to a narrowed base; midrib prominent in age, the veins
