Aplopappus NuTTALLir, T. & G. Torrey, Sitgreave's liep., p. 162, t.2\. 
Canescent with a fine pubescence; stems numerous, a span high from a 
branching woody base, leafy ; leaves obovate-cuneate, about V long, 2" wide, 
pinnately toothed, the teeth elegantly bristle-tipped ; heads few, in terminal 
corymbs; involucres campanulate, 4-6" broad; the scales imbricated in 
several rows, oblong or linear, rigidly chartaceous with scarious margins, 
the greenish tips abruptly contracted and spreading ; rays none ; disk-flowers 
about 25 ; styles with very hispid triangular-lanceolate appendages, scarcely 
'longer than the stigmatic portion; achenia turbinate, silky-villous; papj^us 
white, of copious very unecpial scabrous rigid bristles. — Saskatchewan to

it. R. Siirv., 7. 12, t. 6. Shrubby, glabrous, 1-2° high; branchlets slightly 
wing-angled ; leaves alternate, sessile, 6-9" long, narrowly linear-s|)atulate, 
1 -nerved, entire, mucronulate ; heads terminal, solitary or in simple corymbs, 
large, 5-9" wide ; involucre hemispherical ; the obtuse scales imbricated in 
several rows, their margins scarious and lacerate-ciliate; flowers 30-40, all 
tubular ; achenia top-shaped, densely villous-lanate ; pappus short, of 20 or 
more bristles, spatulate-clavellate towards the tip, plumulose below, a few 
shorter subulate ones intermixed. — A very interesting plant, for which a 
separate sub -genus, AcamptojJajjjms, was provided, (P/. Feridl., J. c.f) but the 
pappus is so very peculiar that it might well be made the type of a distinct 
genus. California, (Coulter;) San Felipe, iSew Mexico, (Park's Expl. ;) St.
