Stems erect, stout, pilose throughout, sparingly branched, the branches op- 
posite; leaf blades lanceolate-oblong, 8 cm. long and 2.7 cm. wide or less, some 
of the uppermost blades ovate, mostly obtuse or rounded at the apex, rounded 
at the base, the lower ones with short but distinct petioles, the upper sessile, 
soft-pubescent or pilose on both surfaces or sometimes almost glabrous, thin and 
soft, the leaves spreading; inflorescence panicled, its branches opposite and soft- 
pubescent, leafy, the reduced leaves oblong and rounded at each end, the 
branches with many glandular hairs among the pubescence; involucres on 
pedicels 10 mim, long or less, about 12 mim. in diameter and 7 mim. high, the 
lobes ovate, obtuse, soft-pubescent; flowers 10 mm. long, rose-purple; stamens 
3, scarcely exserted, the style long-exserted; fruit 4 mm. long, rather obtuse, 
S-ribbed, the ribs smooth but the spaces between them strongly tuberculate, 
sparingly and minutely hispidulous. 
Type in the herbarium of the Missouri Botanical Garden, collected at Mani- 
tou, Colo., August 20, 1885, Fritchey 28. Readily distinguished from the species 
by the soft, divaricate leaves which are not acute and not as much wider at 
the base as those of the species, by the soft pubescence, and more leafy 
inflorescence.
