Among the Neckere none of the hitherto described species will accord with that here figured, nor will any of those belonging to Leskea, a genus to which it has an almost equal claim.

The plant of all others to which it approaches the nearest in general habit, is doubtlessly Climacium dendroides (Hypnum nobis); and even in its peristome it is not far removed, for the teeth of the inner fringe are perforated, but not so remarkably as in that plant; and the columella, it may be observed, is not at all exserted.

Has. In ripa fluminis Brinoci inter Atures et-San Fernando, in arboribus quarum radices aquis obtecte sunt. Barba de palo Hispanis nuncupatur. Humboldt et Bonpland.

Caules fasciculati, spithamei ad dodrantales, flexuosi, foliis de- stituti, ramosi, rami plerumque breves, clavati, quandoque in- novationibus elongatis (f. 2). Folia (f. 3) dense imbricata, erectiuscula, subflexuosa, oblongo-ovata, parum concava, acuta, apice serrata, pallide fusco-viridia. Perichetialia ( f. 4, 5,8) reliquis minora, strictiora, magisque dense imbricata. Seta vix ulla. Capsula (f. 5) minuta, foliis brevior, ovata vel tur- binata, erecta. Operculum (f.6) planum, centro umbonato,

This singular species of Grimmia has much the habit, as it has the mode of growth, of Cinclidotus fontinaloides, or of some species of Fontinalis in an injured state. There are no leaves, nor the appearance of there having been any on the main stems, whilst the short lateral branches are thickly terminated by them. These leaves are moreover very thin and membranaceous. The capsule is very small in proportion to the plant, and quite con- cealed by the perichztial leaves. The teeth are much curved in-

wards, pale coloured, obtuse, and jagged or cleft,

like Grimmia ovata,

Has. In umbrosis montis Quindiu, ad radices Quercus Grana- tensis juxta la Quebrada de Toche, altit. 1050 hexapod. Humboldt et Bonpland,

Caules vix semiunciales, repentes, substellatim ramosi, basin versus radicibus parvis fibrosis instructi (f. 2). Folia (f. 3) undique laxe imbricata, subpatentia, mollia, ovato-acuminata, integerrima, parum concava, reticulata, nervo ante medium evanescente. Perichetialia (f. 3) magis angusta, enervia. Sete numerose, vix tres lineas long, erecte, paululum cur- vate atque incrassate, pallide, apicem versus attenuate (f. 2). Capsula (f. 6) erecta, turbinata, sub-apophysata. Calyptra dimidiata (f. 5). Operculum (f. 4) conicum, ob- tusum, Peristomium (f. 6,7) octo-dentatum, dentibus ho- rizontalibus, geminatis, flavis, transversim striatis,

This plant accords so well, not only in habit but also in the general structure of the teeth, with the genus Falronia* of Schwaegrichen, that I can have little hesitation in placing it in that genus, to which I would assign the following character: Seta lateralis. Perist. simplex dentibus 8-geminatis. Calyptra dimidiata. Thus will the number of its teeth distinguish it from Pterogonium, and the lateral insertion of the fruitstalks from Octoblepharum. From the hitherto described species of Falro- nia the present differs in the entire leayes as well as in the form and texture of the teeth of the peristome.

Among those species of Pterogonium having their nerveless leaves imbricated on all sides of the stem, Pé. intricatum and repens have many characters in common with the one here figured and described. But besides that in all its parts (the most minute that this genus), its leaves are more and shining yellow green,

I am aware how liable I am to censure in assigning this plant to a genus different from that in which Dicranum flecuosum holds a place; since with that it accords so well in habit, in the foliage, and particularly in the fringed base of the calyptra. But with the genus Dicranum the more essential character, taken from the peristome, is wholly at variance ; and even with Didy- modon | cannot satisfy myself that the teeth agree in being placed in pairs. The habit however does not materially differ, and the teeth resemble in form those of many Didymodontes; and in Didymodon capillaceum and heteromallum it is not easy to dis- cover the approximation of the teeth in pairs. ;

Did. gracile has a striking peculiarity, not only in the long and slender, rigid stems, but also in the colour, which below is a deep and shining brown, inclining to black; whilst above it is of # pale and bright yellow hue.

Iregret being obliged to differ from so learned and so acute a botanist as Mr, Brown, who in the 10th Volume of the Linnean Transactions has constituted of this and some allied species having a membranous ring to the mouth, the genus Leptosto- mum. But much as I could wish to see the plants he has there brought together (which certainly have a very peculiar habit) Separated from the other Gymnostoma, yet the doin oblige us to remove also G, Griffithianum, G, microstomum, and some others which have no character in common with the Leptostoma of Brown, but the annular Membrane ; and this is to be discovered with so much difficulty that I believe it would often escape the notice of the most accurate investigators,

There can be, I think, no doubt of this being the J. flabellata of Labillardiére, although I cannot find that the exterior calyx in my specimens accords with what he has represented. With respect to the shortness of the interior calyx, as described by M. Labillardiére, that is in consequence of its being in a young state, for he was not acquainted with the perfect fructification. As in J. Lyellit and hibernica (with which this plant has many points in common), this part increases in size as.the fructifieation advances,

Although at first sight this may appear very near to J. flabel- as there are nevertheless abundant points of distinction. The stipes is shorter and the fronds longer. These latter have never their — SO numerous, nor are they spread out so as to form an orbicular outline: add to these the distinctly toothed Margins of he frond and the differently shaped exterior calyx. .

This Jungermannia is one of the most striking in point of size, and the most singular in structure, of any in the rich Men- ziesian collection, It is full as large as the J. nobilis (already figured), to which it bears at first sight no inconsiderable resem- blance. But here the leaves have the lesser lobe, not a conti- nuation or expansion of the margin of the larger one, as in that species, in J. memorosa and many others ; but it actually grows out (if 1 may use the expression) of its superior surface; =i age larger lobe itself, particularly towards the extremity, is cut into segments so deeply and regularly as to be almost pinnated,

We have among our British Jungermannie two species (viz. J. viticulosa and J. trichomanis), which have calyces pendent on the stalk; but then they are buried in the ground, or in the mosses and other plants among which they may happen to grow. In the present instance the calyx grows from the extre- mity of an erect stem, or which is curved only, as it would ap- pear, from the weight of the fructification, and there is pendu- lous. On the exterior surface of this calyx, near the mouth, is a cluster of pistilliform bodies, apparently covered by a mem- brane, and these are present at the same time with the perfect capsule, In the foliage and stems this plant has great affinity with J. asplenioides,

Those mosses having the peristome of a Trichostomum or Di- dymodon, and lateral fruit, were formed by Schwaegrichen into the genus Leucodon. This we adopted with much satisfaction in the Muse. Brit.; but being then acquainted with only one species, we subjoined to the character “a dimidiate calyptra,” which that individual possessed. Here we have a species with the same distinguishing marks, except that the calyptra is mitri- form. For the present, however, J shall suffer it to remain with Leucodon; and if during the progress of this little work I see the same reason to consider the different form of the calyptra as essen= tial in distinguishing genera as I do now, I shall constitute of this and of an allied species from New Holland (L. rugosus, MS.) a genus under the name of Lyedlia.

This comes under Sir James Smith’s Mnium, as characterized in the Linnean Transactions (vol. vii.); but surely it is contrary to nature to separate this from the genus of Bartramia tomen- tosa and arcuata, merely because of the more oblong form of the fruit. With the two species now mentioned this has the closest affinity; so much so that I believe no other character than the shape of the capsule and relative length and direction of the fruitstalk can be found to distinguish them. This, too, has truly the peristome of a Bartramia.

On the first aspect of this plant I conceived that it and some other Australasian individuals with the same habit would have be- longed to the genus Sclotheimia of Bridel and Schaegrichen; but after the most minute investigation I am unable to detect any in- ternal peristome (though I think that the columella, which before the ripening of the capsule is exserted, might by a casual observer be mistaken for one), or any character which can induce me to keep it distinct from Orthotrichum, many of which, as is suffi- ciently well known, have only a single peristome.

This is another species with the same habit as that figured at Tap. XXIV., and with the same remarkable calyptra. A similar ealyptra Mohr has attributed to a moss which he says is nearly: related to Aniclangium cirrosum of Hedwig,. and to another from Oronoko; but in both these, which he has included in his genus Ulota, there is an inner fringe exactly as in Neckera. The pre- sent plant differs from O./ongipes in the lengthened narrow leaves,. the shorter fruitstalks, and distinctly sulcated capsules.

Orthotrichum gracile has at first sight, not only in its leaves but even in the fruitstalk and capsule, the aspect of Trichostomum patens; the calyptra, however, and the teeth prove it to be of the same family with our. O. longirostrum and longipes. From ‘those it differs in its long stem, proliferous branches, which give the fruit so often the appearance of being lateral, and especially in the long narrow and flexuose leaves.

This approaches very near to the Leskea filiculeformis, the L.rotulata, and Leskea (Hypn., Schwaegr.) tamariscina of Hed- wig. From the first it differs in its much smaller size but larger leaves, and in its branches being never regularly twice pinnated;

There is a striking peculiarity in this plant from the regularly distichous, horizontal, and conduplicate foliage; circumstances in some degree belonging also to J. albicans, to which this plant in natural habit is allied. Here, however, the leaves have their lobes and segments equal in length, and their vente margins most beautifully ciliated.

It is probable that the fructifieation of this plant will be found to resemble that of J. albicans j—unfortunately, there is no ap- pearance of any in Mr. Menzies’s specimens,

This plant in its bright and upright foliage is not much unlike Neckera trichophylla of Swartz (Hypn., Hedw.) ; but the peri- stome is very remarkable: and were it not for the membrane from which the peristome rises (exactly as in the inner fringe of Neckera and Hypnum), it would very satisfactorily accord with the genus Leucodon, where it may, at least for the present, be allowed to remain. I can in no instance find a double peristome, nor the least appearance of its having existed on any one of the many capsules which I possess. But it must be observed that I have not had the opportunity of examining a capsule upon which the operculum was found.

This species will rank near Hookeria (Lesk., Hedw.) albicans. The very pale, almost white, colour is common to,both. Our plant is much larger, more straggling in its growth; the fruit- stalks are much longer; the leaves very obtuse, entire, slightly papillose at the back, with short nerves and a very minute reti- culation. In both the calyptra is multifid at the base, but the divisions are longer in this; both too are smooth, not marked with reticulations, of which the interstices are sunk so as to form Pits or hollows, as in Hook, lete-virens and ducens.

There are several European species of Jungermannia (such as J. nemorosa, J. undulata, &c.), with a habit similar to the one here figured, and with leaves of a like form; but none, that I am. yet acquainted with, which has the stipules placed on the same side of the stems with the larger lobes of the leaf. In this par- ticular our plant differs most remarkably from J. tomentella, with. which at first sight it may appear allied, and naturally ranks with J. appendiculata and J. nobilis of the Musci Exotici, It is. remarkable in its leaf-bearing calyx (such as is seen in J..com= pressa and a few other British species), and in its pubescent fo- liage and stipules.

This singular plant no one will hesitate to pronounce as nearly allied to J. juniperina of Swartz. It has the same rigid texture and dotted appearance in the foliage, vered by leaves,

and the calyx is equally co- Here, however, the ramification is very pecu- liar, being closely pinnate with deflexed branches, and has given rise to the specific name. The fructification too is axillary, and the leaves, which are only bifid in juniperina, have their seg- ments again divided in J. Scolopendra.

This most remarkable moss, of which I have not had the good fortune to see the calyptra, accords so well in the other parts of its fructification with the genus Aniclangium, especially with A. ciliatum and imberle, that I have little hesitation in placing it with and near those species. The rest of the plant is never- theless totally different from them ; and were it not for the strong nerve in the leaves, might be readily mistaken for some Junger- mannit.

Throughout their whole length the stems are covered beneath with a thick ferruginous down, intermixed with stipules, and the leaves, which grow in a distichous form, are, when dry, so much curled as to cover the whole upper surface of the stem, and if macerated for ever so great a length of time continue involuted in a most remarkable manner.

The stems and unmagnified leaves of this little plant resemble those of Bryum julaceum more than any other moss; and its ge- neral habit is that of a Pterogonium, It is however a true Gy- mnostomum, as far as I am capable of judging without the ca- lyptra, which I have neyer yet seen, although it does not bear much affinity to any of the other species of this varying genus, The nearest is perhaps G. estivum; in which, as well as in this plant, the perichetium is highly worthy of remark 3 but in their leaves the two species are totally different from one another.

It must be confessed that this species comes very near to N. seductrix ; but its much larger size, longer fruitstalk and operculum, together with the broader, more evidently acuminated and entirely nerveless leaves, have induced me to keep it distinct.

It is not easy at first sight, except by the decidedly sulcated capsule, to distinguish this plant from Anictangium cirrhosum of Hedw. (Sclotheimia? Schwaegr.); but when the leaves come to be more accurately examined, they will be found to be neither so long as those of .4. cirrhosum, nor in the least serrated. The operculum and calyptra I have not seen ; but judging from the general habit of the plant, this latter may be expected to resem- ble that of O, longirostre, gracile, and their affinities.

So closely does this moss border upon the Sclotheimia squar- vosa of Schwaegrichen, that I can hardly point out any essentially distinguishing character between them except in the calyptra, which is by no means alike in the two plants. I have therefore greatly to regret that in all the specimens I possess of O. apicu- latum the capsules are either not sufficiently, or else too much, advanced to exhibit a peristome.. Those in the latter state are quite destitute of teeth ; and as to those upon which the oper- culum still remains, I can, on removing this part under the mi- croscope, discover nothing but a pulpy mass filling the hollow of the lid, the external substance of which, when the capsule is arrived at maturity, probably forms the peristome.

Until T can satisfy myself as to the real structure of the teeth, I shall place this species among the Orthotricha, where it will rank naturally enough with O. longipes, O. gracile, O. longi- rostre and longifolium,—differing however from all in the form of the leaves,

In the Muscologia Britannica it is proposed that the genus Hedwigia should be confined to those mosses whose capsules have a naked mouth and lateral fruitstalks, Such is the case in the present instance ; and so it is with another Humboldtian moss, which differs from this in many particulars, and which I shall soon take occasion to publish in this work. In both there is a considerable resemblance in the leaves to those of Anictan- gium ciliatum and imberbe,

Various travellers, besides Mr. Menzies and Mr, Burchell, have brought this noble Jungermannia from the island of St. He- . Jena, where the latter gentleman informs me it grows only on the upper side of horizontal branches of ancient trees on the highest peaks in the interior of the island; such as are constantly wetted by floating mists and clouds, It is a most picturesque object, growing always in very large and dense masses, and varying from red to a pale green,

This species, which is plentiful with fructification, is the more interesting because the only one to which it bears any resem- plance, our J. cochleariformis, has never been found with ca- lyces; and from the close affinity between the two plants, it is natural to suppose that the fructification is also similar. As a species J. sphagnoides differs from J. cochleariformis principally in the form and circumscription ‘of the leaf. The auricle is nearly the same in both,

This is a plant the general structure of whose leaf is similar to that figured at Tas.

It is besides considerably smaller ; and at first sight its general habit resembles starved specimens of J. sphagnoides, so much so that the learned botanist to whom | we are indebted for its discovery had actually marked it in his MSS. as the same species,

If the structure of the leaves of Jungermannia appendiculata and J. Thouarsii, already figured in this work, excites our atten- tion as differing most remarkably from what we have hitherto known of the genus, those who take delight in beholding the varying hand of Nature in her minutest productions will be no less gratified by the examination of the present species. In those just mentioned we perceive a lesser lobe or division of the leaf, arising from the surface or disk of the larger portion; but here, from the exterior surface of two distinct lobes, are lamelle or plates, totally unlike any thing I am acquainted with in vegeta- ble ceconomy, running nearly the whole length of the lobes, and distinctly toothed. The extremities of the leaves are cut into lobules, or rather pinnules, as in J. appendiculata. Beneath the stipules are tufts of small scales, as there are likewise in an- other Menziesian Jungermannia, which I shall have occasion to gore g. 1, plant nat. size. Fig. 2, leafandstipule.

The specimens here figured were communicated to my friend Mr. Lyell, by Francis Boott, Esq. of Boston, New England, a gentleman whose ardent thirst after botanical knowledge has in- duced him to visit this country; and who, in conjunction with. Professor Bigelaw*, of Harvard University, is now preparing for publication a Flora of the New England States.

Although bordering very closely upon Polytrichum undulatum, this plant may with certainty be distinguished from it by the great breadth of the nerve and its distinct lamelke, and by the shortness of the operculum. To these characters may be added the much narrower capsule, its léss inclined direction, the nar- rower and more carnose leaves, and the much smaller size of the whole plant. Schwaggrichen does not seem in his specific cha- racter to have chosen those marks which will distinguish it from P. undulatum ; and he has introduced into his synonyms plants of Michaux and Dillenius, which appear to me to be only varie- os of P. undulatum, which is also a common plant in North

merica.

Of the genus of this plant, although I am not so fortunate as - to possess ripe capsules, there can be no doubt 3 since in its ha- bit, as well as in the leaves and calyptra, it has so great a con- formity with the Hookeri@. Nor can I be at a loss for a spe- cifie character, the calyptra being cleft into a number of long and narrow segments, as in some Orthotricha from the same country, and the fruitstalk being in a most remarkable degree hispid; in this respect resembling the Neckera scabriseta of Schwaegrichen.

This is one of the largest species which I am yet acquainted with of the genus Hookeria, and cannot be mistaken for any other. The leaves are similar to those of H. pallescens (vide Tas. XXXVIII.); but the rest of the plant is totally different, the calyptra especially, which is beset with the paraphyses (of Hedwig) as well as the pistilliform bodies, both of which are very numerous about the perichetium.

In one individual out of a great number of specimens which I have examined, I found the calyptra cleft on’ one side about a fourth of the Jength upward. This I suppose to be an acciden- tal circumstance, as we know it sometimes to happen in the ge- nus Grimmia and Trichostomum ; and, taking it for granted that the veil is in reality mitriform, I place this plant among the Hookeria, though I regret to say it does not accord in habit with any other species of the genus. The general appearance of the plant is that of a Neckera ; and its capsule is, as in that tribe and in most Leskee, erect. Those who have most studied the mosses will be best aware how difficult it is to form generic cha- racters from the parts of fructification, which shall include only those individuals which appear allied by nature.

This plant will come into the same family with J. platyphylla and J. filicina, and may be placed near the latter, though abun- dantly distinct from both. I have in my possession a Junger- mannia, communicated to me by M. Richard from the Isle de Bourbon, that is scarcely to be distinguished from this except by the texture of the leaves, which in M. Richard’s plant are curi- ously dotted in a similar manner to those of J. Turneri and J. Woodsii : but this circumstance, taken in conjunction with the very different places of growth and some other peculiarities, has determined me to keep the two plants distinct. Of J. flagellifera I have only seen very young fructification.

Totally different at first sight as this Jungermannia may ap- pear from J. reptans; yet when the leaves and stipules come to be minutely examined, the similarity between them is so great, that I hardly know whether I am warranted in making this a di- stinet species, The marks upon which I rest my doing thus are, _ the much greater size of J. pendulina; its erect habit ; its being regularly pinnated, with flagelliform and pendulous branches bare of leaves towards the extremities 3 and lastly, the difference of texture, which is here composed of small distinct reticulations, while in J. reptans the substance is elegantly dotted,

I may here observe that the J. cupressina of Swartz, whose description will be found in many points to accord with this spe- cies, does not appear to me to have any character which can essentially distinguish it from J. reptans, which is found in va- rious distant countries.

The very large, transversely oblong and closely imbricated sti- pules will readily distingush this species from any other with which I am acquainted. I think I am correct in considering it to be the J. Billardiert of Schwaegrichen ; his words being “ J. caule erecto subramoso, foliis imbricatis ovatis acutis omni margine serratis, stipulis arcuatis dimidio minoribus ;?’—and I am the more inclined to think them one and the same plant, because M. La Billardiére has given me very fine specimens, which he gathered in Van Diemen’s Land, of the same species, but with- out a name.

It must be confessed that this moss comes very near to our Grimmia ovata, though it is of a much larger size, and altoge- ther of a stouter habit. The main difference between them must however rest on the length of the operculum, which in the pre- sent plant is full three fourths of the length of its capsule. The calyptra, though a truly mitriform one, is sometimes seen to be so cleft on one side that it assumes the appearance of being di- midiate,

In the present species the leaves are remarkable in having the nerve occupying the entire breadth of the leaf, in the margins of the leaves being not in the least involute, nor at all serrated. The leaves are likewise more patent than in any other individual of the genus with which I am acquainted ; the fruitstalks are longer in proportion to the size of the plant, as is also the oper- culum.

This very distinct species of Bartramia was named in honour of its discoverer, by Mr. Turner, in a most excellent paper on the genus, published in the first volume of the Annals of Botany. Hitherto it seems but little understood by the continental bo- tanists, Schwaegrichen only placing it among his doubtful or lit- tle known species, and observing that ‘habitu similis B. gra- cili,’ (B, Gideri.) From this latter, and indeed every other, this plant may be readily distinguished by its long slender stems, and appressed leaves which are broad at the base and lanceolate,

and which terminate in a long narrow subulate point.

From all the hitherto known species of Bartramia the present may be easily distinguished by its very long, spreading, flexuose and subulate leaves, That to which it most nearly approaches is the variety called crispa of B, pomiformis; but, independently of the greater length and narrowness of the leaves in the plant now under consideration, the nerve is by no means so distinct, but vanishes upwards into the substance of the leaf, as in B. ithy- phylla, Its habit too resembles that of B, squarrosa of Turner, (B. patens Schwaegrichen,) but differs from it in wanting the very strait and rigid leaves,

sited

With all the habit of a Neckera this plant is possessed of a pe- ristome, which, according to the characters laid down by Hed- wig, should constitute it a Leskea. 1 cannot, however, resolve on separating it from a genus in which N, planifolia, which it so very strongly resembles, is placed ; of which latter species it may also be observed, that it possesses, in common with the subject of the present plate, the membrane uniting together all the inte- rior teeth of the peristome. This is a very stately plant, having upright stems, bare of branches at the base, and thickly clothed above with bipinnated ones, which, as well as the leaves, are al regularly bifarious. Those of the main stems are strikingly like the leaves of N. pennata, while those growing on the branches are nearly orbicular.

The present curious plant belongs to the same division of the genus as J. dilatata and J. Tamarisci; like them having the lo- bule of the leaf or auricle terminated, at least on one of its seg- ments, by aclubshaped vesicle. Here indeed these appendages are not confined to the leaf, for there are two on the middle seg- ments of the stipule, and the whole underside of the plant has a most singular appearance from the number and regularity of the vesicles. The calyx, however, differs remarkably from J. dilatata, and the rest of its affinities, and more nearly resembles that of J. juniperina, being altogether covered by leaf-like scales.

In the last plate (Tas. LXX.) was given a Jungermannia which, like the present figure, had saccate or hollow claviform appendages, both upon the lesser lobe of the leaves and upon the stipules. There is also a considerable resemblance in the two plants in the colour, the general ramification, the foliaceous ca- lyx, and the quadrifid stipules. J. paipebrifolia nevertheless differs from J. clavigera in the beautifully ciliated margins of the leaves, of the cauline stipules, and of the foliaceous scales of the calyx.

JUNGERMANNIA ERIOCAULA,

The first aspect of the plant now under consideration induced me to believe it not specifically different from the J. fucoides of Swartz, which name is equally applicable to the present species, as it bears, both in texture and ramification, a great resemblance to the Fucus cristatus y of Turner. But a more careful inspec- tion, with a view to the drawing and description, satisfied me that U had fallen into an error; for not only are the segments of the fronds narrower,—with nevertheless a broader nerve, which gives to the whole plant a more carnose appearance,—but, what

is a more important character, the caudex (or rachis of Swartz) which in J. fucoides is smooth, may in this species be observed to be covered on both sides with a short, brownish or ash- coloured pubescence, very apparent under a magnifying lens.

In those pubescent Jungermannie whose foliaceous branches, if I may thus express myself, arise from a trunk of a different or firmer texture, as is the case in JJ, Alalellata, J. trichomanis, and the present species, I find the structure so very similar to that of many individuals of the fern tribe, that I cannot do better than employ the same terms for different parts of the plant as are adopted by Willdenow, in his volume on the Ferns in the Species Plantarum,

It is onlv from the close analogy of this plant to Trichostomum vaginatum, figured at tab. 64, that I am induced to place it in that genus; for not only are my specimens destitute of a perfect peristome, but also of the calyptra and operculum. So nearly: indeed are the two species allied that an inexperienced eye might, on their first aspect, judge them to be thesame. In the subject. of the present plate the leaves when carefully examined will be: found to be never involute at their margins, also to be much.

Like the species just men- tioned, Mr. Menzies also observes of this, that it grows suspended from the branches and about the roots of trees in the north-west eoast of America.

I regret much the not possessing the calyptra of this species, which in its leaves comes nearest perhaps to Polytrichum hercy- nicum, but in other particulars is very different. Indeed its quite entire leaves, (of which the texture is like that of the last-men- tioned species and P. undulatum and angustatum,) together with the narrow nerve, exactly ovate capsule and subulate lid, will

keep it distinct from any other with which I am acquainted. Fig. 1, 1, plants, nat. size. Fig. 2,2, leaves. Fig. 3, capsule and lid, Fig. 4, peristome.—magn.

The teeth of my specimen of this moss are too imperfect to allow me to ascertain decidedly whether it belongs to the genus Didy- modon,—yet | think that it iscertainly a species either of that or of the genus Weissia,—but to whichever of these it be referred, there can be no doubt of its being entirely distinct from any hitherto described plant: and from the similarity of its leaves to those of some species of Splachnum I have derived its trivial name. I have received specimens of this plant both from the learned Pro= fessor Richard of Paris, and from M. Coulon of Neufchatel, a gentleman to whom I am indebted for many interesting crypto- gamic subjects from the West Indies,

Two other individuals of the genus Hypnum (H. basilare and spiniforme) have the same remarkable upright and Bryum-like mode of growth as the present species, which differs from the former in its having leaves which are narrower and marginated, and not at all bifarious, and in its nearly erect capsules, and which may be immediately distinguished from the Jatter by its almost erect, less rigid and broader leaves, and by the insertion of the fruitstalk, which, while it is in the present plant at the origin of the branches, is in H. spiniforme at the very base of the plant, among the roots, Authors have described H. spiniforme as having distichous leaves, which is not the casein my specimens so that it and EH. mnivides will rank in the same division of the genus, and ought to be placed close to each other.

So very thickly are the leaves and stipules crowded upon the stems of this plant, that it is not without great difficulty that their real structure is discoverable. It differs in many particulars from any species hitherto described, but comes nearest to one figured in the next plate from the Isle de Bourbon, and will pro- bably rank in the same division with J. trilobata. 1 have already noticed as being squamose, the stems of another J ungermannia = lamellata), though they are not so much so as in the present plant,

This and the immediately preceding species of Jungermannia (J. squarrosa), though coming from very different parts of the world and from totally different climates, have nevertheless a very great affinity with each other in the mode of growth, colour, the svaly stalk, the texture, and the general form and direction of the leaves and stipules. The principal points of distinction be- tween them will be found to be the much smaller size of J. jfim- briata, and its having the leaves and stipules narrower and more deeply cleft, with their segments recurved and their margins most beautifully ciliated.

At Tas. LX. of this work is given a Jungermannia, (J. pen- dulina) which is only to be distinguished from J. reptans by the different mode of growth and ramification. The present plant altogether resembles that in its size, mode of growth, and rami- fication ; yet the extreme minuteness of the leaves and stipules, and the distance at which these are placed from one another are so striking, that none would perhaps hesitate at first sight in pro- nouncing it distinct. But when these differences are pointed out, (and they are very constant in all the specimens which I possess,) nearly all that’ean afford marks of discrimination between the pre- sent plant and J, pendulina are mentioned; for, on subjecting the leaves of the former to a high power of the mi pe, they will be only found to differ from those of the latter in their extreme minuteness, their more quadrate figure and nearly plane surface. °

The specimens which I have received from Guadaloupe are smaller, and of a paler and yellower green, but are like those of Mr. Menzies in every other particular.

P. levigatum affords an excellent specimen of the curiously lamellated nerve of the leaf, which in a greater or less degree is common to all the species of the genus which have come under my observation. Wahlenberg, its first and indeed only describer, mentions the back of the leaf as having this appearance, if I un- derstand his words rightly, ‘ foliorwm dorsum undulatim dila- tatur,” which is not the case with my specimens ; yet there can, I think, be no doubt as to the identity of the plant. Schwae- grichen has quoted it, though doubtfully, under the P. /evigatum of Bridel, which has leaves that are marginate and serrulate, and — with which it can therefore have no affinity.

I am indebted to the learned Professor Richard of Paris for: specimens of this most remarkable and beautiful moss, whose: habit at first sight certainly resembles those speeies of Dicranum which Hedwig and most of his followers have called Fissidens,. and in that genus Schwaegrichen has already placed it: He,. however, appears to have been equally unfortunate with myself in not being able to describe the Peristomium. Besides the: curious form of the leaf, much more scymitar-shaped than that of H. trichomanoides, there is a striking peculiarity in the nerve, which in most mosses is placed in the centre of the leaf, whilst here it runs close along the lower Margin; in this respect ap- proaching the structure of the leaf of the Fissidentes, but wanting the dilated and conduplicate base, Here too, unlike the species of that genus, the leayes spring alternately from the anterior and posterior sides of the stem.

The distantly placed branches, the regularly patent leaves, the long slender fruitstalks and pale green colour of the whole plant, give to this little moss rather an elegant appearance, whence I have derived its specific name.

It is with much pleasure that I acknowledge the kindness of Professor Swartz, who has enabled me to publish this species which in so many particulars agrees with the Jungermannia eriocaula, (Tas.

In addition to the differences be- tween them there noticed, I may add that J. fi ucoides. has the fronds (pinne of Swartz) more distantly placed, their divisions. far less numerous, more patent, broader, more decidedly reticu- lated, of a browner colour inclining to reddish, of a thinner tex- ture, and having a nerve much narrower in proportion to the dia- meter of the segments.

Schwaegrichen has described the leaves of this Jungermannia -a8 quadrifid, though in my specimens they are usually emargi- nate; but it often happens that near the apices of the segments. there arise tooth-like processes so large that the extremity may be considered tri- or quadrifid, or more properly, perhaps, tri- or quadri-dentate, Of J.

The leaves approach nearest to those of J. asple- nioides, as does the general habit of the plant ; but the fructifica-. diem, which is very remarkable, bears a greater resemblance to that of J. Sphagni.

This species is very nearly allied to J. spinulosa, differing from it in the form of the leaves and denticulation, and like that, pro- bably subject to great Variations. It well accords with Swartz’s description ; but among the specimens under that name which I have received from that liberal naturalist are two kinds, which, if they do not differ specifically from the one here described, merit at least a separate figure as very remarkable varieties. Indeed in Mr. Menzies’s collection are two other Jungermannie which I can only find to differ from the present, the one in its smaller size, the other in its almost simple mode of growth, more distantly placed and broader leaves, They are all found in Dusky bay, New Zealand.

The fructification of J. conjugata greatly resembles that of J. adiantoides and spinulosa ; but a decided mark of discrimi- nation may be found in the leaves, which are truly united at their

hase all round the stem, and thus the plant becomes perfoliate in a most remarkable degree.

Although the leaves and fructification of z ramosissima re. semble very much, at first sight, those of J, conjugata, yet they differ not only in their direction, but essentially in their never being connate. To J, spinulosa it is even more nearly allied : the foliage however is very dissimilar, the plant is vastly more branched, and there is a peculiar elegance of character arising from the regularity in the size and direction of the leaves which is wholly wanting in the former.

Different as this species is in reality from the preceding one, . (J. ramosissima) yet I have found it very difficult to express this - difference clearly in words. The present plant is vastly more: stout and robust in all its parts, the stem very rigid and of a black - colour. The leaves larger, more horizontal in their direction, more inclined to quadrate, more ciliated, and altogether of a much darker hue. A greater point of distinction may be found in the: calyx, which is less urceolate, and in the capsule moreover, which is oblong. The vastly larger size of the plant, repeatedly branched: stems, the shorter fruitstalk and more ciliated leaves, are the principal marks which distinguish this from J. aspleniotdes.

This very elegant plant may be considered to approach nearer to J. trilobata than to any other species with which we are at - present acquainted, but is at once distinguished from it by its beautifully ciliated leaves and stipules, which give to the whole plant, even when seen by the naked eye, a peculiarly tomentose appearance.

Caudex repens, hic illic radicibus tomentosis obtectus. Stipites plurimi ex eodem caudice subunciales, filiformes, flexuosi, sub- erecti, glabri vel radicibus tomentosi. rons uncialis fere longa, ovato-lanceolata, carnoso-membranacea, minute reticu- lata, fusco-viridis, margine undulata, omnino integerrima, basi attenuata, apice obtusa, nervo tenui obscuro percursa.

This species, again, like J. rhizobola, is most clearly allied to J. Lyellii, and hibernica, differing however essentially from them in the presence of a caudex and stipes, in the much thicker tex- ture of the frond, as well as in its different outline.

JUNGERMANNIA HORIZONTALIS.

Stipule valde minute, sublunulate. Calyx inramulis propriis brevissimis, ex parte inferiore caulis egrediens, lateralis, oblongo-ovatus, ore sub- contracto, brevi-laciniato, laciniis denticulatis.

J. horizontalis may be immediately seen to be very nearly in- deed allied to a well known British species, J. polyanihos, hav- ing precisely a similar habit, leaves very nearly the same, and what is more remarkable still, its fructification on short horizon- tal branches arising from the under part of the stem. There is, however, a very striking difference in the stipules, in the dilated posterior base of the present plant, and also in the colour ; this being, in most of the specimens that Mr. Menzies has gathered, of arich brown. I have seen no individuals possessing perfect fruit ; so that whether or not the corolla be exserted beyond the calyx, as in J. polyanthos, 1 am unable to say.
