Nelson New Plants- from Nevada. 175 



July, 97 ; both collections from Mount Rose, Nevada, probably from near 

 the snow bank on the northwestern slope of its volcanic summit. I name 

 Doten's specimens as the type. 



Bosleria Nevadensis gen. et sp. nov. 



A small viscid-pubescent annual with the branching habit and the leaf 

 aspect of Physalis; tap-root-breaking up into fibrous roots ; floral characters 

 near those of Solanum; flowers minute, less than 5 mm. long; calyx cleft 

 nearly to the base into oblong subacute segments ; the tube of the corolla 

 very short, its limb rotate-campanulate, with 5 short triangular acute lobes ; 

 stamens inserted in the throat of the corolla, a little shorter than the corolla 

 lobes ; the filaments relatively broad, not so long as the conspicuous anthers; 

 connivent anthers open terminally by very evident pores but also easily 

 rupture by longitudinal slits ; fruit not known ; probably a berry. 



The above description is a preliminary announcement of this solanaceous 

 plant which seems to represent a very strongly marked genus. It was 

 collected by Mr. G. H. True at Pyramid Lake, Washoe Co., Nevada, June 

 9, 1903. Prof. Kennedy expects to collect in that region this year and 

 hopes to secure it again in quantity for complete characterization. This is 

 the second monotypic Solanaceous genus that Nevada has furnished, the 

 other being Oryctes Nevadtnsis. I wish to dedicate the genus to my college 

 friend, Mr. Frank C. Bosler, of Carlisle, Pa., whose scholarly interest in 

 scientific work is greatly appreciated, and whose active interest in the 

 development of the West both as regards its educational phases and its 

 physical resources makes such recognition fitting. 



Artemisia Kennedy! sp. nov. 



Perennial from rootstocks, 6-10 dm. high, the stems erect, simple, 6-10- 

 striate, puberulent ; leaves 5-12 cm. long, numerous, mostly lanceolate, the 

 lower more or less dentate and laciniate, the upper and floral entire, acute, 

 all green and glabrous on the upper face with often numerous minute 

 scattered resinous particles, permanently and closely lanate-tomentose on 

 the lower face; panicle narrow or sometimes freely branched below and 

 thus pyramidal, 3-5 dm. long, quite leafy below but the leaves passing into 

 linear bracts above; heads crowded, ovoid, 3-4 mm. high, involucre per 

 manently white-lanate ; its bracts involved in the wool, broadly spatulate, 

 the margins and the upper half membranous; flowers liberally sprinkled 

 with large resin particles, 12-20 in number, about equally divided between 

 the slender marginal pistillate ones and the larger hermaphrodite ones of 

 the disk, all fertile. 



Mr. C. V. Piper in his article, New and Noteworthy Northwestern Plants 

 (Bull. Torr. Bot. Club, 28 : 42), clears up the confusion as to that maritime 

 species which has been known by.^the untenable names A. valgaris Cali- 

 fornica Besser, and A. heteroptfylla Nutt. To this plant he gives the name 

 A. Siiksdorfii and definitely limits it to the sea-coast species. That was in 

 fact done by most of the earlier writers as well, but some collectors and 

 writers have confused with it this inland species of the same general habit
