JUNGERMANNIA.* (Common Receptacle of the Fruit none:
Perianth or Calyx monophyllous, tubular, rarely wanting:
longer than the perianth. Hook. E.) (Many of these plants afford singularly beautiful microscopic objects. For
a fuller account of the parts of fructification, see vol. i. p. 349 and 370 of this work; and the subject elegantly illustrated in a Monograph of British Jungermanniæ by Dr. Hooker, wherein nearly one hundred species are described. E.)
(Named by Ruppius and Micheli in honour of Lewis JUNGERMANN, a native of Leipsic, and Professor of Botany at Altdorf and Giessen in the early part of the seven teeoth century. He published Illustrations of the Flora of Germany, and formed a five Hortus-siccus, wbich is still preserved at Altdorf. E.)

SUBDIVISIONS OF JUMGERMANNIA.
A. Plant unbranched and without a mid-rib.
2. Leaves winged; fruit-stalks lateral, or at the base. C. 1. 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.

Mull. Frid. 2. 6 and 5. Leaf variously scolloped and curled at the edge, pale green, firmly fixed to
the mud by fibres from its under side. Weis. 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. Filuments 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 segments, discharging a yellow brown powder mixed with fibres. This being done, the old leaf dies, and one or more young ones shoot out.
Dill (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. 7. 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

branches always more or less forked. In the month of March, on * plants of this description the branches become wider and of a deeper colour, and gradually partake more of the usual appearance of the plant: roots descend from their under sides, and the old frouds seem to, be going into a state of decay: so that these curious processes are, in all probability, destined by nature as a mean of increasing the species, different from any that has yet been noticed in other Jungermanniæ.

so as to form light, pellucid, green patches of many inches in diameter, and firmly adhering to the ground by its roots. In the calyx, two remarkable peculiarities may be observed, in the widely-expanded mouth, and the stipulaceous processes, or bracteæ, as they might be called, at the base. The situation, too, of the fructification is very curious, unaccompanied by perigonial or perichætial leaves; and the whole plant diffuses an agreeable odour, not unlike that of the Sweet Sedge (Acorus Calamus.

this otherwise diminutive plant. Purt. E.) (DWARF JUNGERMANNIA. J. pusilla. Linn. Hedw. Huds. With. Relh.

Leaves lying one upon another, in which way it appears to increase till it has covered a large patch of rock. (When moist and first gathered, it exhales a fine aromatic scent, which, uniting with the fragrance of certain Mosses, imparts to the air a peculiar and refreshing odour, often perceptible from grassy walks under trees or shadowy rocks, especially after showers. Prof. Hooker perceives no difference between this plant and J. multifida, except that the frond is somewhat wider, and the divisions frequently, but by no means constantly, so short that the margins appear to be here and there sinuate, rather than cut
into segments. E.) (JAGGED JUNGERMANNIA. J. multifida var. ß sinuata. Hook. E.) At
