SUBDIVISIONS OF JUMGERMANNIA. 
A. Plant unbranched and without a mid-rib. 
B. 1. Leaves winged; fruit-stalks terminal. 
2. Leaves winged; fruit-stalks lateral, or at the base. 
C. I. Leaves winged; leafits with appendages; fruit-stalks terminal. 
2. Leaves winged; leafits with appendages; fruit-stalks lateral, or 
at the base. 
D. Shoots tiled with leafits. 
A. Plant simple , without a mid-rib. 
J. epiphyl'la. (Stem none: frond bluntly lobed, bearing the sheaths 
on its upper surface, with a little leaf at the base of each.

Leaf variously scolloped and curled at the edge, pale green, firmly fixed to 
the mud by fibres from its under side. W eis. Fruit-stalks hollow, two 
inches high. Scop. Bears its fruit in the spring, but flowers in autumn, 
the barren flowers appearing like dots on the older leaves, and the fertile 
ones in the cylindrical sheaths. Involucrum of one leaf, irregular, 
wrinkled. Germen globular, smooth, on a very short fruit-stalk, which 
is ensheathed. Lower part of the involucrum fixed in a kind of groove. 
Style very short. Filaments on the germen of no determinate number. 
Knapp. Leaf short, roundish, moderately broad; segments blunt, 
shallow, fine green, pellucid. In winter a dark green head appears upon 
the middle of the leaf. In spring this head breaks forth from a valve on 
the surface of the leaf, circular and open at the top, afterwards cut into 
four shallow segments. Out of this the fruit-stalk rises, growing rapidly 
to the height of one and a half or two inches, white, pellucid, supporting 
a dark green globe which opens into four brownish and roundish seg¬ 
ments, discharging a yellow brown powder mixed with fibres. This 
being done, the old leaf dies, and one or more young ones shoot out. 
Dm: 
(In the situation of its anthers, observes Professor Hooker, J. epiphylla 
differs from every known species; they being placed singly, and im¬ 
mersed in small scattered tubercles upon the surface of the nerve. E.) 
(Var. y. furcigera, of the same author, is most abundant in autumn, when 
the apices of the fronds are produced in a very remarkable manner; 
forming branched elongations, which are considerably more narrow, 
and of a paler green than the rest of the frond, and have the ultimate 
recognize the power of the Creator great even in those things which ignorance regards as 
too minute to merit attention : for we thus perceive each little herb complete in its own 
peculiar structure, and beautiful in its symmetrical proportions, as the most magnificent 
productions of His hand : and to the observant eye, (the mental as well as corporeal 
vision), the stately monarch of the forest will be scarcely an object of more profound 
admiratioo, than the definitive Moss ! E.)
