nately were cut down before they could be fully studied suggest its 
presence north of the city in the vicinity of Winnetka. ; 
That it differs from the ordinary black oaks to the eye of other than : 
botanical observers is evident from the fact that an intelligent farmer 
had separated it from its congeners, calling it “ yellow oak,” and remark- 
ing the tendency of the lower limbs to die. No chestnut oaks, to : 
which this name commonly applies, grew there, so that it could in no : 
way be confounded with this, even if the leaves were not so different. 
Looked at in the summer it gives the impression of great leafiness, the 
leaves being small as a whole, and of airiness on account of its glossy 
and finely divided leaves. In the winter it impresses by the glitter of 
its smooth bright branches when free from leaves, and by its great 
twigginess, due to the spray repeatedly and finely dividing, forming a2 
irregular network as one looks through it. 
As the form of the acorns first suggested specific difference, and on 
the whole is the most constant characteristic, the name Quercus ellip- 
sotdalis seems most appropriate.—E. J. Hiti, Chicago, Ii.

THE WYOMING SPECIES OF ANTENNARIA-. 
Most valuable and efficient work has been done recently by 
Greene* and Rydberg? in the long neglected genus Antennaria. 
critical examination of the material in the Herbarium of the Univer’ 
sity of Wyoming in the light of these contributions has 3 ee 
discovery of a few forms, hitherto undescribed, which seem worthy 
Specific rank. It has seemed well, also, to make mention of all Wyo" 
ing species of which specimens are at hand. ; 
Antennaria reflexa, n. sp.— Low and cespitose, somewhat i 
neous at base, with very short leafy offsets ; stems 5-10™ high: lea
