H a b . — In marshes and wet woods, and by the margins of ponds
and streams ; very common from Newfoundland and New Brunswick,
through Canada westward to the Saskatchewan, and in the United
States from Maine to Florida, extending to Lake Superior and Louisiana.
Mexico and Cuba to Brazil. Europe, Asia, Africa, and the Mauritius.
Apparently absent from the western side of both the American
continents, unless possibly it is in the Sierra Madre of North-western
Mexico.
D e s c r i p t i o n . — The root-stock creeps just beneath the surface
of the ground, or even at the surface, advancing an inch
or so every year, and slowly decaying at the older extremity.
The existence of a plant probably continues many years, as
the old and decayed remains of the root-stock may sometimes
be traced for two or three feet. The root-stock itself is slender,
scarcely more than two lines in thickness ; but it is so covered
with imbricating stalk-bases and by interlacing roots, that the
whole is massive, and often has a diameter of two or three
inches.
The stalks are continuous with the root-stock, and indeed
inseparably united with it: the part above ground is roundish,
but flattened on the upper or anterior side, and smooth, except
for a little pale-brown deciduous cobwebby wool. The single
fibro-vascular bundle is in section horseshoe-shaped, with in-
