204 Rhodora [NOVEMBER 
The entire group occupies a piece of ground less than three feet in 
diameter, and very likely has originated through root suckering from 
a single plant. How the original plant got there is another question; 
but from the location of the station—near the summit of a rocky 
ridge which has never been inhabited, and fifty feet from the nearest 
road, from which it is separated by a tangle of wood and thicket— 
it seems certain that the plant was not introduced by human agencies. 
Moreover, the redbud here occupies essentially the same sort of habi- 
tat which it favors on trap ridges in eastern Pennsylvania: a moist, 
rocky depression in oak-hickory woods, where it grows associated with 
such other woody plants as basswood and butternut, silky cornel and 
high bush blueberry, bittersweet and grape.. In short, I have no 
hesitation in accepting this Connecticut station for the redbud as 
representing a northeastward extension in the known natural range 
of the species, notwithstanding the fact that it apparently fails to 
propagate itself further by seed.
