548 PROCEEDINGS OF THE ACADEMY OF [1896. 



axil ; petals about a line long, bifid, deep red-purple : capsule about 

 4 lines long, of oblong-lanceolate outline, curving outward, about 

 50-seeded : seeds dark brown, glabrous, somewhat angular, and of 

 subclavate-oblong outline. 



Dry bed of the upper Humboldt River, near Deeth, Nevada, 

 Aug. 5, 1895. 

 Valerianalla magna. 



Glabrous, the stout stems sharply angular, 3 to 5 feet long, tortu- 

 ous, half-reclining on fences or among bushes, and with rather many 

 small axillary branches : cymes thyrsoidly congested at the ends of 

 the stem and branches : corolla white, bilabiate, with ample funnel- 

 form tube and a short thick spur : fruit glabrous externally, tri- 

 quetrous-ovoid, the ventral concavity formed by the ample wings 

 closed below, open above, the wings themselves strongly hispid-ciliate 

 within. 



Collected only by the author, in Knight's Valley, Sonoma Co., 

 Cal., June, 1894. Species noteworthy on account of its great size 

 and half-climbing habit; the fruit showing an affinity with V. aphcir 

 noptera. 



Valerianella oiliosa. 



Slender, erect, simple, seldom a foot high, corolla small, deep 

 pink, very distinctly bilabiate, the rather slender and tapering spur 

 much longer thau the body and produced far below the ovary : fruit 

 of roundish outline but modified by a very prominent stout apicula- 

 tion, the back glabrous, provided with a very broad ribbon-like 

 though distinctly bevelled keel, which is very densely ciliate along 

 both margins, the subrostriform apiculation bearing similar hairs, 

 the turgid-margined abruptly inflexed wings revealing the ventral 

 cavity by an elliptic acute opening. 



Plentiful on northward slopes of low hills west of Napa Valley, 

 California, growing with V. macrocera ; but very distinct, no less in 

 fruit characters than in form of corolla. 



Lessingia peotinata. 



Slender and very diffuse, the ascending or more widely spreading 

 and almost prostrate branches a foot long or more ; herbage scarcely 

 woolly even when young, green, sparingly stipitate-glandular and 

 scabrous throughout ; only the lowest leaves woolly, these and also 

 those of stem aud branches pectinate- pinnatifid, the segments pun-
