242 NELSON : NEW PLANTS FROM WYOMING 
“ Anogra violacea sp. nov.* 
Biennial or possibly more enduring, from a vertical, semi- 
woody taproot: stems several to many, erect with a decumbent 
base, 2-3 dm. high, violet or purplish throughout (or at least 
broadly splotched), appearing smooth but puberulent under a 
lens: crown-leaves rather small, linear-oblanceolate, entire or 
toothed, few if any of them surviving the first season: stem-leaves 
puberulent, dark green, numerous, 4-8 cm. long, linear-oblong or 
narrowly oblanceolate, coarsely sinuate dentate and some of them 
deeply pinnatifid, the lobes acute, triangular to oblong: flowers 
axillary, congested at the summit of the stems: buds drooping, 
oblong or slightly enlarged towards the obtusish tip, pubescent 
with flat crinkled hairs which are densest at the apex : calyx-lobes 
a little more than half as long as the tube, tips free: petals tri- 
angular-obcordate, sinus broad and shallow, 1-20 mm. long, 
scarcely longer than the calyx-lobes, white, drying pink: young 
capsule largest near the base, tapering gradually to a slender 
apex, subangulate, sinuate-tubercled on the margins, sparsely 
hispid-ciliate, about as long as the calyx-lobes. 
This species probably finds its nearest ally in A. adbicaulis 
(Pursh) Britt., from which its numerous, erect, violet stems, its 
glabrous aspect, its smaller flowers and its divaricate capsule easily 
separate it. 
It occurs in the greatest profusion in sandy draws in south- 
central Wyoming. Type specimen xo. 3075, Point of Rocks, June 
I, 1897. 
~ Pachylophus glabra sp. nov. 
Acaulescent and completely glabrous throughout: perennial 
(possibly short-lived), from a thick deep-set semi-fleshy root which 
is caespitosely branched at summit ; the enlarged crowns rough 
with the old dead petioles: leaves crowded on the crowns, nearly 
linear, 7-12 cm. long, remotely and irregularly toothed on the 
margins, tapering to both ends, acute at apex, at base passing 
gradually into the slender petiole which is about half as long as 
the blade: flowers not equalling the leaves ; the calyx-tube slen- 
der, only slightly enlarged at the throat, 1 dm. or less long; 
calyx-lobes about 2 cm. long: petals somewhat inequilateral, 
broad, deeply cleft-cordate, about 2 cm. long, white, turning pin 
in fading: the versatile anthers and the filaments subequal, about 
* The description of this species wes prepared some years since but was withheld 
from publication. Dr. Rydberg now kindly writes me that he has received it in good 
fruit. <‘‘ The fruit is narrowly linear-cylindric, standing out at right angles to the sem 
and therefore in (sharp) contrast to A. albicaults.”’
