ANTENNARIA IN THE MIDDLE WEST 81 
of white which, on close inspection, is found to belong to the 
lower face of the leaf which is to that degree rolled in at the margin 
before its full expansion. Now it can not be allowed in Antennarta, 
as we have been learning its characteristics these last fifteen 
years, that the same species, on the same spot—or in different 
localities, for that matter—shall appear partly with foliage per- 
fectly glabrous above from the start, and partly with this hoary 
above with a wool that is deciduous; and this is the case in two 
of the well developed plants on what is a part of the type material 
of A. campestris. Out of this difficulty I am helped by two other 
sheets in the U. S. Herb., the numerous specimens on which are 
all from the Black Hills of South Dakota, the same region where 
Dr. Rydberg collected his specimens. One of these two bears 
specimens of two species, the other as many specimens all of 
one kind, without admixture of any even doubtful A. campestris. 
8.. A. parvula. Planta pumila, caule 1-3-unciali. Folia 
semiuncialia, saepissime ovalia, interdum suborbicularia, utrinque 
incano-tomentosa. Capitula pro planta magna, pauca, sub- 
sessilia. Pappi setae maris apice vix incrassatae, scabro- 
serrulatae. 
Black Hills, South Dakota, near Fort Meade, collected by 
Dr. W. H. Forwood in 1887; seven specimens on U. 58. Her. 
sheet 317207, three of them fertile, the rest sterile. Also by the same 
collector, and mounted on sheet 317750, fine specimens of A. 
parvula and two of the plants with leaves green and glabrous 
above, to which it seems best to have the name A. campestris. 
The distinctions between the two are not merely those of 
the permanency of the indument. This is not even tardily deciduous 
from the upper half face in A. parvula, while as already affirmed, 
in the other it does not at all exist at any stage of the half’s devel- 
opment; but the leaves in A. parvula are so short as to appear 
almost orbicular now and then; and while the pappus in its 
male is almost filiform at tip, and mostly barbellate, that in A. 
campestris—not mentioned in the original description—is very 
obviously thickened as well as quite smooth, or at best faintly 
crenulate. 
9. A. Lunellii. Planta pumila, caule vix biunciali, sto- 
lonibus elongatis crebre foliosis. Folia latiuscula, semiuncialia 
et ultra, interdum fere uncialia, spathulato-obovata, superne 
leviter sericeo-tomentosa, indumento vix, vel tardissime deciduo.
