NATURAL HISTORY. 
The iT nobeatin PERFOLIATUM is a coarse, unattractive 
plant, growing in rocky woods. It delights in rich limestone 
soil, on rocky or stony ground, preferring the shade, though it 
is frequently found in different situations. Its range is from 
New England to Carolina, and probably farther. It flowers 
in June and July, and the seeds ripen in September. 
The root is perennial, horizontal, about eighteen inches or 
two feet long, three quarters of an inch in diameter, and 
fleshy, nearly of a uniform thickness from the extremity to 
within two or three inches of the origin of the stems. At 
this place it is contorted, tuberculated, or gibbous, and of a 
brownish color. The color of the horizontal caudex is yellow- 
ochre without and whitish internally, and the fibres which 
_ proceed from it are of an ochroleucous hue. These are some- 
times so large that they may be considered rather as branches 
- forks . f the main root. The plan is from two to: three | 
fet high, and darth papel stems arising from ‘the: same
