asimilar distribution and history. Originally described by 
Michaux with a habitat ‘‘in rupibus circa Knoxville,” it was 
afterwards discovered in Kentucky by Dr. Short, and in the 
mountains of Virginia by Prof. Ruffner, and traced to Arkan- 
sas and Texas by Nuttall, Dr. Pitcher, Drummond and others 
(as A. Pitcheri). About 1870 Prof. H. H. Babcock detected 
it on the limestone formations of the Des Plaines river at Riv- 
erside just west of Chicago.* It occurs in considerable abund- 
ance in some localities of limestone within the city limits near 
Windsor Park and on Stony Island, and also beyond them at 
Lamont on the Des Plaines. It is reported from one locality, 
Tippecanoe co., Ind.,* between these stations in Illinois and 
its southern range.

ulent fruit, so much so that the figures of the fruit given in 
Coulter and Rose’s ‘‘Notes on the Umbellifer of the United 
States,”> though true as to the wings, do not cover these cases. 
his is specially the case with plants on the opposite shore of 
ke Michigan at Benton Harbor, Mich. In these the inter- 
vals of the ribs are strongly puberulent with short, blunt hairs, 
much as in T. pinnatifidum. ‘ 
ECHINACEA ANGUSTIFOLIA DC.—Found on a small prairie 
fast of Durham, a station on the L. S. & M. S. R.R., in La- 
Porte co., Ind. As but a few plants were seen beside the 
‘ssa it may possibly be an introduced plant, though more
