30 miles below the town of Glendive, Montana. They come from 
strata usually referred to the Fort Union Group, but the beds.ap- 
pear, from the similarity of fossils as well as from their position at 
the base of the section, to be of the same horizon as the beds at 
Iron Bluff, which rest upon the Fox Hills Group. It is therefore 
possible, as Prof. Ward has pointed out (Bull. Geol. Soc. Am. 1: 
531), that these beds may represent the Laramie. 
I take great pleasure in naming the species in honor of Prof. 
Ward, its collector.

Botanical Notes. 
Steironema intermedium, Kearney.—Dr. Charles Mohr calls my 
attention to the fact that the form of this species collected by him | 
in Talladega county, Alabama, differs from the type in having the 
stems decumbent or ascending. 
In the figure of this plant published in the BULLETIN of the | 
Torrey Club,* the staminodia were inadvertently omitted. These 
afford another excellent character for distinguishing the species- 
In Steironema ciliatum they are subulate-lanceolate, tapering from 
the base to the very acute apex. In .S. intermedium they are of 
the same form, except that the apex is less subulate, but are from 
one-third to one-half as long. In S. radicans, finally, the sterile 
filaments are yet shorter and are comparatively broader and more 
abruptly pointed than in’ S. intermedium. 
Gray (Syn. Fl. N. Am. 2: Part 1, 61), describes the bottom of 
the corolla and the filaments of Steironema as “ granulose-glandu- . 
lar.” As these glands have distinct, though very short stalks, the ay 
term is not strictly applicable. In S. radicans the filaments are 
naked or with very few glands, while the corolla is much less 
glandular than in S. ciliatum and S. intermedium. ;
