994. Antennaria umbellata Greene, l. c., p. 82. — Planta feminea 
saepissime pedalis, caule tenui summitate capitulis 5—9 tenuiter pedi- 
cellatis et sub-umbellatis coronato. Folia biuncialia, lamina late ellip- 
tica petiolo aequilonga, superne primum levissime villoso-tomentosa, dein 
glabra. Involucrum late-campanulatum; squamae angustae, subequi- 
longae, apice angustissime et vix conspicue scariosae. Planta sterilis 
fertili dimidio minor, ejus capitula 3—5 subsessilia; pappi setis apice 
manifestim dilatatis sub: serratis. — This fine species was discovered 
by the writer, in eompany with Dr. Nieuwland, in the vicinity of 
Benton Harbor, Michigan, 27 May, 1909, the special habitat being the 
crown of an open hill jutting forth from a piece of woodland, the ex- 
posure being northward. The fertile and sterile plants were growing 
together; but from the fertile alone the species is easily distinguishable 
from all others of this broad-leaved group. Its heads are slenderly 
pedicellate, and form usually a loose subumbellate corymb. The scales 
of its involuere are very narrow and not manifestly imbricated, being 
of nearly equal length, in this differing from, I think, every other an- 
tennaria known, and the scarious tips of the scales, being narrow and 
little elongated are nearly as inconspicuous as those of A. mesochora. 
The plant will be found in other localities of southern Michigan and 
northern Indiana when once the exploration of the region for antennaria 
shall be carried forward beyond what are hitherto its first beginnings.
