NEW OR NOTEWORTHY SPECIES. : 71 
lected by Mr. John Macoun, no. 447; distributed for Aster 
radulinus, and later referred by me to EHucephalus Engel- 
mannii, from which its pubescence, serrated foliage and nar- 
row pubescent involucral bracts completely distinguish it. 
MACHJERANTHERA TAGETINA. Related to M. tanacetifolia, 
of similar habit, the root doubtless annual: herbage rough- 
ish with a short spreading pubescence, some of the hairs 
gland-tipped: leaves consisting of an oblanceolate long ter- 
minal lobe and two or more pairs of remote linear short 
pinnules below it, the reduced ones of the branchlets smaller 
and with less inequality between the terminal and lateral 
lobes: heads about half as large as in M. tanacetifolia, the 
involucres turbinate, their bracts in about 3 series, closely 
imbricated and wholly erect, the linear white-chartaceous 
lower part much longer than the subulate-linear erect and 
hardly acute green tips: rays few (12 to 15); achenes (im- 
mature) densely silky-villous. 
Of this species, remarkably distinct from all others known 
in character of foliage and involucre, only a flowering branch 
apparently broken off from what may have been a large 
plant, is preserved in the U.S. Herbarium. It was collected 
by T. E. Wilcox in 1891, at some unrecorded station in 
Arizona. 
MACH.ERANTHERA COMMIXTA. Stems 6 inches high more 
or less, apparently from a perennial root, reddish and gla- 
brous below, hirtellous-scabrous above: leaves large for 
the plant, spatulate, serrate, 3-nerved : involucres several in 
a terminal corymb, large, campanulate, their bracts in 3 or 
4 series, broad, with triangular-subulate viscid-granular 
spreading green tips: rays many, large and showy. 
From the Henry Mountains, Utah, 1894, by Marcus Jones; 
the specimen preserved in the U. S. Herbarium, mounted 
with specimens of the next. It might be referred to the 
Colorado M. Pattersonii but for the conspicuously 3-nerved 
leaves and the characteristie involucre of broad short-tipped 
bracts.
