Hab. Moist, shady banks, especially on a clayey soil, where it is not of unfrequent 
occurrence; bearing its fructification from October to the end of the spring. 
The Plant grows either in detached individuals, or thickly matted together so as to form patches 
of many inches in diameter, and firmly adhering to the ground by its 
Roots, which are long, dense, simple, issuing from the whole length of the under side of 
the stem, and of a remarkably deep purple color.
