    Hedwig observes that all the female florets have a dou- ble cdlyx, or a Cup and a Blossom. In shape and struc-t hire he says they greatly resemble the proper Mofses, but tfmt he never found the succulent threads; the Pistil-Hke substances are however found, accompanying both the germcn and the ripened capsule ; but not in all the species. The Capsule, like those of the preceding Mofses, is inclosed in a Veil, to which the style adheres; but this Veil is not as in them, loosened at its attachment and raised along with tlic growing Capsule, it tears open in two, tliree, or four places, and has therefore been sometimes considered as a petal. All these Mofses agree in ripening their fruit, which is raised u];x)ii an elongated fruit-stalk, and opens into 4 Valves, tilled with the seeds, attached to elastic cords, 'hhese seeds proved upon trial to reproduce their respec- tive plants^ JUNGERMANNIA nernorea. It bears its male, or barren tlowers, which are of a reddish brown colour, at the summit or extremity of the Stem, in one plaijt, and its female florets at the extremity> of another plant, lb. xiv, f. 30.

The germen of the female plant, with its pistil, and 3 pistiUlike bodies at its base, taken from the calyx leavps at the top of the plant, JUNGERMANNIA asplenkides* The extremity of ihe male plant forms a beautiful tiled, two-rowed Involu- ennu of leahts, very conegve at the base, within each of v/hich are found 2 or 3 stamens of a milky colour. The female flowers are on a distinct plant, included also in a leafy calyx or perichaetium, at the top of the plant, f. 35. A male plant of its natural size, f, 36. The tiled leaves at the extremity of the plant, •which includes the anthers. f. 37. An anther taken out of the Perichsetium or leafy calyx. f. 38.
