A FASCICLE OF NEW COMPOSIT#, 61 
Collected on the Moqui Indian Reservation in northern Ari- 
zona, 22 Aug., 189%, by Myrtle Zuck, the type in my own her- 
barium. 
CHRYSOTHAMNUS VIRENS. Shrub stout, several feet high, 
both leaves and branches of a deep dull green, neither notably 
viscid nor at all woolly; leaves about 2 inches long, firm and 
subcoriaceous, linear, very acute, strongly 1-nerved, but with 
also a lateral nerve close along each margin, and the upper face 
rugulose by short tranverse veinlets connecting the medial with 
the lateral nerves: heads very many, in dense large corymbose 
compound cymes: involucres short (the corollas twice as long), 
their bracts in mostly 4 series, all of more or less triangular 
outline, not carinate, scarcely acute, glabrous, not viscid: corolla- 
tube not slender, loosely hispidulous, teeth of little more than 
one-fourth the length of the throat, obtusish, not spreading : 
style-tips hispidulous: achenes appressed-silky. 
Plains of southern Colorado, and adjacent foothills, especially 
in the upper Arkansas Valley; the type specimens of my own 
collecting, at Cafion City, 7 Sept., 1896. 
CHRYSOTHAMNUS LEHTEVIRENS. Larger than the last, often 
4 or 5 feet high, the branches and foliage light-green, both 
glabrous or nearly so, only the inflorescence obviously viscid- 
resinous: leaves very narrowly linear, about 3 or 4 inches long, 
acute, attenuate at base and subpetiolate, very distinctly 3-nerved, 
. the midvein depressed, the laterals elevated: terminal flower- 
clusters ample, corymbose-panicled: involucres narrow and 
elongated, their bracts in 4 series, all the outer carinate, acute, 
the inner oblong-linear, obtusish, all very viscid on the back and 
shortly ciliolate at least below the apex: corolla with short 
slender tube beset with rather many short incurved pairs and a 
few long straight slender ones, or these last occasionally wanting; 
segments rather deep, spreading: achenes very silky. 
Plentiful on the plains about Grand Junction, Colorado, col- 
lected only by the writer, 27 August, 1896.
