Acamptopappus microcephalus n. sp. Widely branched 

 shrub, about a foot high, season's growth about 3 inches long, 

 slender; leaves acute, linear-spatulate, about 6 lines long, clus- 

 tered on the branches; ncdes about 2 lines apart on the lower 

 stem and leaves short and fascicled in the axils cf larger 

 leaves, puberulent, resinous; plants leafy up to the filiform, 

 bracteate, delicate pedicels which are 6 to 9 lines long; heads 

 corymbose, 3 to 5, broadly obovate, 3 lines long; scales nearly 

 smooth, outer ones barely greenish at tip, imbricated in about 3 

 series, broadly ovate to oblong, all but the inner ones acute, these 

 fimbriate on the margins, 1 to 2 lines long; flowers 6 to 10, 

 nearly twice as long as the inner scales, rayless, receptacle not 

 fimbrillate; akenes densely villous with hairs bidentate at the 

 apex; pappus of rather few bristles distinctly enlarged above 

 and with some outer ones nearly as long and not enlarged, 

 pappus as long as the flowers. This might be classed equally 

 as well as an Aplopappus, but the habit and pappus are those 

 of Acamptopappus. Lone Pine, Inyo Co., Cab, on rocks, 4000

 linear, 1 to 2 inches long, 1 to 3 lines wide, acute, nearly double 

 the internodes; heads 3 to 4 lines long exclusive of the rays
