Leafits serrated. At first sight distinguishable from all other Hypna by its shoots being very long, very closely crowded together, covering the trunks of trees, in broad patches and hanging down. Shoots trailing, very tender, brittle when dry, a span long, or more, clinging to the trees by means of numerous brown, woolly fibres. Leafits small, triangular, ending in a hooked hair, alternate, in a double row. Weis. From a span to a foot in length, doubly winged. Leaves very small, triangular. Fruit-stalks an inch long, purple. Capsules dull green, brown when ripe, short, nodding. Veil pale green, straight. Dill.

D. (1) Leaves bent back: capsules upright.

H. RUGO'SUM. Shoots scattered, rather upright: leaves pointing one way, wrinkled at the base: fruit-stalks axillary.

Dicks. H. S.-(E. Bot. 2250. E.)—Dill. 37. 24.

Leaves spear-shaped, narrow, sharply pointed, closely tiled. Pol. Shoots seldom more than three inches long, thick, lying on the ground, crowded together, irregularly branched. Leaves exceedingly crowded, dry, crisp, their points in one direction, yellow green, when old or dry quite yellow. The fruit-bearing plants grow a little distant from the others, and have a different appearance. They are thinner, more pointed, the leaves more uniform, and less yellow. Involucrum open, scaly, at the origin of the branches. Fruit-stalks three quarters of an inch high. Capsules cylindrical, straight, slender, red when ripe. Dill.

Fertile plants entirely green, except here and there a little purple. Dill. (One of the largest of British Mosses; with leaves generally nerveless; but, according to Schwaegrichen and Mr. Tozer in Musc. Brit., occasionally two nerved; which shows how liable this, like most aquatic plants, is to vary. E.)

H. CUPRESSIFOR'ME.

(Leaves closely imbricated, more or less falcatosecund, lanceolate, acuminated, entire except at the points, which are usually serrated, very faintly two-nerved at the base: capsule cylindrical, erecto cernuous: lid conical, with a point.

Hedw. Stirp. iv. 23-E. Bot. 1860-Musc. Brit. xxvii.—Fl. Dan. 535—Dill. 37.23 and 41. 53.

So sportive is this plant that it is scarcely possible to define in a few words the marks belonging to any of the varieties. y at first sight is totally unlike the more usual state of H. cupressiforme; but we have seen the one run completely into the other. ß is now universally acknowledged to belong to our plant; and we are equally satisfied of Dickson's nigroviride being no other.

In its tree-like mode of growth it resembles H. dendroides, but the shoots are longer, the trunk is taller, the branches expand more, and are more frequently branched again; the extremities are not straight, but hanging down, and the leaves expanding. When dry the leaves bent back at the points, but in H. dendroides they lie closely adpressed. Weis. Stem four
