988. Antennaria Wilsonii E. L. Greene in Amer, Midl, Nat., IL (1911), 
p. 78. — Habitu et mensura A. neglectae, sed folia et breviora et latiora, 
tomento faciei superioris vix deciduo. Capitula majuscula, interdum 
distincte subracemosa, plantae femineae involucri squamis omnibus an- 
gustis, summitate angustissime scariosis, maris squamis obtusissime obo- 
vatis, summitate inaequaliter dentatis. Pappus maris apice paullulum 
inerassatus et obscure sub lente crenatus. — Collected ,Near Cold Creek, 
Hamilton Co.*, Indiana, 18 April, 1892, by Guy Wilson; specimens 
in my own herbarium and in that of U. S. Museum. In several of the 
male specimens the heads are loosely racemose, a thing never seen in 
A. neglecta, or in any other species whatever. The short broad leaves, 
from which the woolly indument is seldom wholly deciduous, and the 
peculiarities of the involucre in both sexes, compel the recognition of 
this plant as a species. It is from central Indiana, and the collector 
remarks that it is rare.

fertim subsessilia. Squamae involucri plantae femineae latiusculae apice 
subtruncato eroso-lacerae, aut interdum fere pectinato-fimbriatae; maris 
late obovatae, interdum retusae, leviter eroso-dentatae. — Prairies of
