the upper face and on the veins and margins, closely impressed- 
punctate on both faces, the veins on the lower surface raised- 
reticulate, oblong-lanceolate, 2-4°™ long, subacute, from entire 
to irregularly few toothed, usually some small fascicled linear 
leaves in the axils, smaller upward and passing into the bracts 
of the short inflorescence: cymes of few heads, congested- 
corymbose or becoming paniculate: involucre turbinate-cam- 
panulate; the bracts in 4 or 5 series, softly pubescent, strongly 
nervose, resin-sprinkled, shorter than the 12-15™™" high disk; 
the outer short, lanceolate; the inner broadly linear, acute: 
flowers about 25: the corollas linear-cylindric, but slightly 
dilated at base, about 8™ long: style tips compressed, linear, 
not dilated-clavate at summit: akenes 20-striate, some of the 
striae more prominent than the others, linear, about 5™™ long, 
exceeded by the white softly plumose pappus. 
This species is perhaps most nearly allied to A. g/utinosa Ell., but the 
points of distinction are so patent that to call attention to them seems 
unnecessary. 
The only collection of it is no. 2771, Platte cafion, Laramie county, 
Wyoming, August 27, 1896. Some specimens of it were distributed as A, 
eupatoriotdes corymbosa T. & G. 
Lacinaria alata, n. sp.—tTall, 8°" to probably twice as high: 
stem stout, striate, puberulent: leaves numerous and crowded 
(especially on the middle portion of the stem), quite similar 
throughout (root leaves not seen), glabrous, closely and uni- 
formly punctate, linear-oblong, acute; the lower 8-12 long, 
mostly less than 1™ broad, deflexed on the short margined 
petioles, upwardly becoming smaller sessile and erect, passing 
into the large foliar bracts of the spike: spike 3—5%™ long, 
crowded: heads sessile or nearly so, numerous (30-50), about 
15™™ high, equally broad, 35—45-flowered: the involucral bracts 
in about 6 series, minutely punctate, purplish; the outer very 
short, ovate, acute, green, rarely slightly scarious-winged near 
the summit; the succeeding 2 or 3 series similar as to the 
foliaceous center but conspicuously and broadly scarious-winged 
toward summit, becoming broadly obcordate in outline, the 
wings from entire to dentate or even lacerate, about 1™ long
