In the male flowers of Hedwig, the succulent filaments are remarkabl clavate, jointed, pellucid, the joints containing greenish granules. Funaria hibernica has been found only on the roof of a thatched cottage at Blarney, near Cork, Ireland. The long flexuose fruitstalk of F. hygrometrica, one of the commonest of mosses in almost every situation, possesses strong hygrometrical qualities . 2238. Bartramia. So called in honor of John Bartram, an Anglo-American, to whose researches in North America the gardens of Europe owe many of their finest trees. He had a son William, who published in 1773, an account of a journey in the interior of North America. This is an elegant genus of mosses, remarkable for their fine capillary light green leaves, and spherical capsules. The genus approaches nearly to Bryum, but differs in almost every species having a spherical capsule; and the sixteen broad segments of the inner peristome, instead of being entire or only perforated, are cleft like the teeth of a Dicranum. 2239. Pohlia. Named in honor of I. E. Pohl, a German botanist. Small plants, often refered to Bryum, with which they entirely agree in habit. 2240. Bryum. One of the ancient Greek names of moss. These are all dwarf plants producing capsules in abundance, and generally found growing in wet places. In B. palustre are found terminal capitular bodies, which much resemble what are called the anthers of B. androgynum; but in B. palustre they are considered gemmæ, and arise not only from the main stems, but also from the innovations.

Anictangium. From avεiκτoς, open, and aγγεiov, a vase, on account of the open nature of the theca, which is not enclosed by a peristome. The only British species are two plants with nerveless leaves, and the habit of Trichostomum. 2243. Fissidens. From fissus, split, and dens, a tooth, in allusion to the structure of the peristome. Plants generally referred to Dicranum by British botanists, but differing from that genus entirely in habit, and sufficiently in characters. Dr. Hooker remarks, that the structure of their leaves is highly curious, and totally unlike that of any other plant with which he is acquainted. Besides being vertical, their upper half (taking the nerve for the line of separation) is, from the base beyond the middle, composed of two equal lamellæ, the lower part of which embraces the stem, and the rest very often embraces a portion of the leaf placed immediately above it. 2244. Leucodon. Named from λεuκoς, white, and oδες, a tooth, from the color of the peristome. The only British species has occasionally been thrown among the Dicrana, Trichostoma, and Pterogonia; from any of which, an attentive consideration of the lateral fruit, deeply divided teeth, and dimidiate calyptra, will keep its genus distinct. The stems are long, and creeping over the bark of trees. 2245. Fontinalis. From fons, a fountain, in allusion to the places where it grows. F. antipyretica is a common plant, floating in large masses in rivers and pools of water. The specific name was given it because ORD. V. TRIBE II.

Anomodon. So called by the authors of Muscologia Britannica, on account of the peculiar nature of the peristome, which has narrow fringed processes arising from the very same range, and from between the teeth ; avoμoς, irregular, and oδες, a tooth. The stems are dark, almost blackish green, long, cylindrical, and straggling. It is not uncommon on the wilds of Dartmoor. 2247. Neckera. Named after N. J. Necker, a German botanist, who published in 1791, his Elements of Botany, a work which contained more useful imformation than many of his detractors have been pleased to allow. Beautiful mosses, found in woods and upon trees and rocks. N. crispa has more the appearance of some fine tropical moss, than of those of our own country, where it is far from uncommon in mountainous districts, frequently covering a great extent of surface upon the trunks of old forest-trees. 2248. Daltonia. Named in honor of the Rev. James Dalton, a skilful English muscologist. The mitriform calyptra separates this from Neckera. D. splachnoides has only been found by the side of a streamlet on the Secawn mountain, near Dublin, where it grows sparingly in pale green tufts. 2249. Hookeria. This beautiful Hypnum-like genus was named by Sir James Edward Smith, in honor of Dr. Jackson Hooker, F. R.S., &c. professor of botany in the university of Glasgow, of the of William Jackson Hooker, F. R. S., &c. professor of botany in the university of Glasgow, one of the most distinguished of modern cryptogamic botanists, and a gentleman whose public reputation is only exceeded by his private excellence. The Hookera of Salisbury, must give way to this on every account. H. læte-virens has hitherto been discovered only in a bog near Cork. 2250. Leskea. N. G. Leske was an obscure German botanist, of whom little is known, except that he gave 3 N CRYPTOGAMIA.

This remarkable genus differs from all other mosses, in having a theca which splits into four valves, cohering at their ends by means of the persistent lid; it agrees with Sphagnum in having no fruitstalk, but in its room an elongated receptacle, and appears to be a transition from Musci to Hepaticæ. This is, however, only apparent. All the species are natives of rocks or mountains, and are remarkable for their nearly black or dark brown color. 3N3 Order 6. b CRYPTOGAMIA. d a CLASS XXIV.

Plants frondose of a cellulose structure not submersed. THIS order is distinguished from Algæ, with which it was formerly united, by the nature of the theca (a, b), and of the foliaceous frond (c) which is never submersed, and which bears a greater affinity to that of Musci.

HEPATICE. these Hepaticæ differ in being destitute of an operculum or lid to the theca, and, with the exception of Marchantia (d) and Jungermannia, of a calyptra. The order is composed of seven genera, all very different from each other, and forming an assemblage which is only natural in regard to the organs of vegetation. It does not appear possible to reconcile those of reproduction . The herbage consists of a variously dilated frond lying flat upon the substance on which it grows, generally naked, but in many Jungermannias covered with small leaves, which are often divided, but never really nerved, so that, in fact, they should rather be considered dilatations of the frond: the substance is generally loosely cellular, sometimes compact, as in Marchantia, in which Hooker asserts that pores of the epidermis exist. 2253. Jungermannia. Theca 4-valved, supported on a peduncle longer than the calyx. Valves free. 2254. Marchantia. Theca on the under surface of a common peltate pedunculate receptacle. Anthers ima common peltate pedunculate receptacle. Anthers imbedded in the disk of distinct peltate pedunculate or sessile receptacles. 2255. Riccia. Theca spherical, immersed in the frond (not opening), crowned with the style, which is alone protruded. 2256. Anthoceros. Theca stalked, linear, 2-valved, with a central columella to which the sporules are attached. 2257 Targionia. Perianth? globose, arising from the underside of the extremity of the frond, at length opening vertically into 2-valves. Theca globose, nearly sessile, included in the perianth, opening irregularly at the extremity, and filled with spiral filaments. 2258. Sphærocarpus. Thecæ minute, spherical, seated upon obpyriform receptacles, and filled with minute sporules unmixed with filaments.

Named by Nicholas Marchant, in honor of his father John Marchant, the first botanist whom the Academy of Sciences of Paris admitted among its members, in 1666. Soft-leaved creeping plants, with green cellular fleshy fronds spreading over the surface of the ground in wet places. M. hemisphærica and polymorpha are often the pest of the florist, whose flower pots are overrun by them, and continually disfigured. 2255. Riccia. Pietro Francisco Ricci, was a Florentine botanist, who left some of his works to the academy of Florence. Little, generally floating, simple plants, of the nature of which very little is known. Only one kind has been observed in fructification, and that is of a very ambiguous character. The thecæ, or the organs so called, are little round bodies immersed in a cavity of the frond, and containing minute sporules. 2256. Anthoceros. From avθoς, a flower, and κερaς, a horn, on account of the horn-like form of the theca, which old botanists considered to be the flower. Minute frondose plants, with a linear 2-valved theca, containing a columella to which the sporules are attached. In habit they resemble Jungermannia. ORDER VI.

Targionia. So called in remembrance of John Anthony Targioni, a meritorious Florentine botanist, who published in 1734 a work for the purpose of shewing the importance of botanical lectures, with reference to a course of studies in medicine. There was also another Florentine physician called John Targioni Tozzetti, after whom Tozzettia has been named. This genus consists of only one species, which is frondose and lobed. The theca is concealed and almost sessile within the involucre, globose, bursting at the apex, and discharging its sporules mixed with spiral filaments. This genus is very near Jungermannia. 2258. Sphærocarpus. From σφaiρa, a globe, and κaρπoς, fruit, in allusion to the form of the fruit. The plant consists of a roundish delicate membranous frond, bearing on its disk a cluster of obpyriform receptacles, each of which has a globose transparent finely membranous seed-vessel, filled with minute sporules unmixed with elastic filaments. e k RIDIHI THIGRA f CRYPTOGAMIA.
Order 7. ALGE. a C g CLASS XXIV. h a Reproductive organs of two kinds. 1. Thecæ or tubercles variously situated. 2. Sporules or granules naked or immersed in the frond. Plants always aquatic and submersed. THIS order is constituted of the sea-weeds of our ocean, and of the floating scum-like substances of our ditches and rivers. Little is known of the functions which what are called their reproductive organs perform. The nature and structure of those organs are so various as to render it improbable that they should all be destined for the same purposes. The bodies which are called sporules are variously situated; now filling distinct thecæ (a), or even tubercles (6), which are either free (b, c, d), or imbedded in the substance of the frond (e, f); now appearing to be naked and surrounded by an involucre (g); now scattered or arranged in some determinate manner in the interior of the frond. (h) The fronds are either cylindrical (h), or plane (i), sometimes little more more than a mere membrane, sometimes hard and horny, and extended to the length of many feet. Many are articulated (i, k): their line of separation is then called a joint, and the space between two joints an articulation. Professor Agardh, of Lund, one of the most celebrated of modern cryptogamists, and whose disposition of Algæ is adopted here, in his latest work, called Systema Algarum, published at Lund, in 1824, defines the order thus: 66 Aquatic plants destitute of cotyledons and of sexual organs; gelatinous, membranous, or coriaceous; filamentous, laminose, or even leafy; in color green, purple, or olivaceous; jointed or continuous; bearing sporidia" (little transparent bodies containing sporules), " either included in pericarps or scattered over the surface."
The Algæ form one of the three forms of the lowest order of vegetation, Lichens and Fungi the two other. Of the former, many are considered by some botanists to be animalcula, and others, to be the young seedling plants of mosses.
