Notes from Pennsylvania. 
At my solicitation, J. K. Small and A. A. Heller, students of 
Franklin and Marshall College, visited Lycoming County, Penn., 
on the 20th of last August, in order to search for Asplenium 
Jonianum, L. along Lycoming Creek, where it was found by 
McMinn. The cliffs on the east side of the stream were explored 
for a distance of twelve miles, but without success. Those on the 
west side, not easily accessible on account of high water, were. 
left for future examination. is 
From this point the young botanists proceeded to Luzerne 
County and spent the two following days about one of those 
little lakes or ponds, so common on the great mountain-plateau 
of N. E. Pennsylvania. Here they obtained a fine prize in Aster | 
concinnus, Willd., and, had they then been aware of the fact, 
would have brought away a full supply. Mr. McMinn (not | 
“ Minn,” as printed in the Synoptical Flora) wasa civil engineer, 
who resided many years in Williamsport and collected the rarer. 
plants of the region round about that city, as well as of the 
counties further west. He was the first, after the time Of, 
Muhlenberg, to meet with this Aséer in its native haunts, and
