NEW OR NOTEWORTHY SPECIES. 41 
ANTENNARIA NEMORALIS. Blade of radical leaves round- 
obovate to cuneate-obovate, very obtuse and notably mu- 
cronate, 1 to 13 inches long, lightly 3-nerved, glabrate above, 
the rather slender petiole an inch long or more: stolons 
elongated, scarcely leafy except at apex, the growing leaves 
thinly tomentose above, densely so beneath: flowering stems 
(only the male known) 3 to 6 inches high, with linear- 
acuminate bracts: heads 6 or 8, the central sessile, the others 
short-stalked, white tips of the involucral bracts oblong, 
obtuse or truncate: tips of the pappus bristles BEE 
serrulate or subentire. 
Said to be common in groves and open woods about Knox- 
ville, Tennessee; collected by A. Ruth, but the male plants 
only have been sent me; and these resemble those of A. de- 
cipiens (Pitt. iii. 321); but their stolons are longer and more 
depressed; their mature foliage is of another outline, and its 
upper surface is glabrate in maturity, while the tips of the 
pappus-bristles are much broader and less serrate. It is un- 
fortunate not to know the female plant of a species so well 
marked. 
CHRYSOTHAMNUS FORMOSUS. Low, branched from the base, 
forming dense almost spherical masses about a foot high; 
both the branches and very narrowly linear spreading foliage 
white with tomentum ; all the branchlets terminating in a 
large and dense ey me of rather elongated heads; branchlets 
of the cyme and their smaller bract-like leaves white-tomen- . 
tose, but the involucres wholly glabrous, their bracts numer- 
ous, 6 or 7 in each of the very distinet vertical ranks, the 
very short outer ones ovate; the inner successively longer, 
the inmost oblong-linear, all obtuse or acutish: corollas and 
achenes not known. 
A very elegant species, most distinct in habit and char- 
acters of the involucre, found only by the writer, in the 
neighborhood of a mineral spring among the hills a few miles 
‘southwest from Grand Junction, Colorado, 27 Aug., 1896; 
Prrros1a, Vol. IV. Pages 41-52. 11 April, 1899,
