STUDIES IN THE COMPOSIT X. 177 
mens in my own herbarium and that of the U. S. Museum, 
it is peculiarly southern, and perhaps somewhat local. The 
best illustration of it which I have seen is an ample sheet 
in the Langlois collection at the Catholic University, these 
specimens having been obtained by A. Ruth, near Knox- 
ville, Tenn., in April, 1894. An original Louisiana speci- 
men, by Carpenter, is in the U.S. Herbarium, and also a 
sheet of Mr. Kearney's collecting at the Tennessee station. 
Mr. Kearney, in his paper cited above, speaks of the plant 
as “heretofore known only from Louisiana;" but, at the 
place of its first publication in the Torrey & Gray Flora, it 
is credited to some place near Philadelphia " as having been 
seen or obtained there by Mr. Lea. It is, of course, possible 
that the true A. monocephala may yet be found to occur 
overa greater extent of territory than we have supposed ; 
but it may also be merely monocephalous states of genuine 
A. plantaginifolia exist, and that the Philadelphia plant 
may be such. ;
