Among the Nvckerce 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 j and the columella, it may be observed, is not at 
all exserted.

GRIMMIA FONTINALOIDES. 

Grimmia, caule elongato ramoso fluitante, foliis ob- 
longo-ovatis acutis serratis, capsula ovata immersa, 
operculo plano-mammillato. (Tab. II.) 

Hab. In ripa fluminis Brinoci inter Atures et San Fernando, in 
arboribus quarum radices aquis obtectae sunt. Barba de polo 
Hispanis nuncupatur. Humboldt et Bonpland*

binata, erecta. Operculum (f. 6) planum, centro umbonato. 
Peristomium (/! 7) 16-deutatum, dentibus obtusis, plus mi- 
nusve fissis, pallide fuscis. 



This singular speeies of Grimmta has much the habit, as it 
has the mode of growth, of Cinclidolusfontinaloides, 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 sterns^ 
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 perichaetial leaves. The teeth are much curved in- 
wards, pale coloured, obtuse, and jagged or cleft, like Grimmia 
ovata.

This plant accords so well, not only in habit but also in the 
general structure of the teeth, with the genus Fabronia* 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 



Octolleph 



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.

DIDYMODON GRACILE. 



Didymodon, caule dense csespitoso elongato, foliis Ian- 
ceolato-subulatis, pilo longo colorato terrninatis, cap- 
sula erecta cylindracea, operculo subulato, calyptra 
basi ciliata. (Tab. V.) 

Hab. In monte Quindiu, regione temperata, Andes de Cundi- 
namara. Humboldt et Bonpland. 

Caides 3-4-unciales, rigidi, dense caespitosi, simplices vel divisi, 
apicibus attenuati (/. 1). Folia (f*2) erecto-appressa, stricta, 
vel paululum curvata, rigida, inferiora nigricantia, superiora 
flavescentia, omnia lanceolato-subulata, acumine longo pili- 
•formi colorato, sub lente serrulato (f* 4), terminata, nervo la- 
tissimo percursa. Perich&tialia (J\ 3) his minora, nervo te- 
nuiore. Seta sesquiuncialis, erecta, parum flexuosa. Cap- 

sula (/". 5) cylindracea, erecta, intense fusca. Calyptra (f. 6) 
subulata, dimidiata, basi ciliata, ciliis longis. Operculum su- 

bulatum, rectum. Peristomium {f. 7, 8) sedecim-dentatum, 

dentibus longis filiformibus, erectis, pallidis, vix per paria ap- 

proximatis. 



I am aware how liable I am to censure in assigning this plant 
to a genus different from that in which Dicranumjlexuosum 
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 I cannot satisfy myself that the teeth agree in being placed 
in pairs. The habit however does not materially differ, and the 



in 



semble in form those of many Didymodontes ; and 
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 
41 pale and bright yellow hue.

This plant is a Neckera of Hedwig. Should the calyptra, 
which I have not had the opportunity of seeing, prove mitriform, 
it will be Daltonia of the Muse. Brit. It is a truly magnificent 
species, and very unlike any thing with which I am acquainted.

This noble species has the lower part of the stem resembling 
the creeping stipes of many Ferns, and is equally black and rigid. 
The superior part alone is leafy ^ and the leaves are not much un- 
like those of some of the varieties of J. nemorosa; but the sti- 
pules, which are large and as beautifully ciliated as any part of 
the leaves, will keep the two species far removed in an artificial, 
■system. The axillary tufts of leaflike processes are confined, as 
far as I have had the opportunity of observing, to this species.

There can be, I think, no doubt of this being the J.jlabellata 
of Labillardiere, 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. Labillardiere, that is in consequence of its being in a young 
state, for he was not acquainted with the perfect fructification. 
As in J. Lyellii and hibernica (with which this plant has many 
points in common), this part increases in size as the fructification 
advances.

Cap 



This Jungermannia is one of the most striking in point of 
size, and the most singular in structure, of any in the rich Men* 
jziesian 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. nemorosa and many others j but it actually grows 
out (if I may use the expression) of its superior surface; and the 
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 Jungermannia two species (viz. 
J. ritkulosa and J. trkhomanis) , 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- 
imty of an erect stem, or which is curved only, as it would ap- 
pear, from the weieht of th* fr„„r:fi„„..:„_ ..",.,

1 hose mosses having the peristome of a Trichostomum or JDi- 
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 calvptra is mitri- 
Jorm. For the present, however, I 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, 1 shall constitute of this 
and of an allied species from New Holland (L. rugosus, MS.) a 
genus under the name of Lyellia.

grichen as a synonym to Bartramia arcuata, from which the 
great length of the footstalk, its erect (never curved) direction, 
and the decidedly sulcated capsule will always keep it distinct.

This comes under Sir James Smith's Mnium, as characterized 
in the Linnaean Transactions (vol. vii.); but surely it is contrary 
to nature to separate this from the genus of Bartramia tomen- 
tosa and arcnata, 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.

The very perfect state of the specimen of this plant gathered 
by Mr. Menzies has induced me to figure it, although already 
represented by Hedwig in his Species Muscorum. But there 
the leaves are erroneously given entire, and the peristome appears 
to have been unknown to the author.

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 Bride.l 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 bv a casual observer 
he mistaken for one), or any character which can induce me 
to keep it distinct from Orthotrkhum, many of which, as is suffi- 
ciently well known, have only a single peristome.

Tbis is anotber species with the same habit as that figured at 
Tab. XXIV., and with tbe same remarkable calyptra. A similar 
calyptra Mohr has attributed to a moss wbich he says is nearly 
related to Anklangium chrosum 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 0. longipes 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 oiTrichostomum 
patens ; the calyptra, however, and the teeth prove it to be of 
the same family with our 0. 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.

extent of this collection I need not speak, since this work is de- 
stined to contain figures and descriptions of all such as are new, 
and a list will be given towards its close of such as have already 
been described by former authors. 

Although so strikingly distinct from every other species, it may 
not be amiss to observe that the present plant will rank near to

From the first it differs in its much smaller size but larger 
leaves, and in its branches being never regularly twice pinnated j 

from the second, in the stipules, which want the excurrent 

and from the last, in the absence of the setce among 
the leaves. With regard to the Hedwigian L. tamariscina, in- 
deed, it does not accord either with Swartz's description, or 
with the specimen which he has kindly sent to me ; and Swartz 
is the original authority. His plant is destitute of setae, and I 
do not find that it differs essentially from L.rotulata of Hedwig* 
which ought thus to bear the name of tarnariscina. 1 shall have 
the opportunity of saying more of these species hereafter. 

H. laricinum is found as well on the continent of Africa as 
America.

profunde biloba, lobis vel potius segmentis oblongis, undulatis, 

subtortis. Substantia mollis, reticulata, areolis parvis rotun- 
datis. 



There is a striking peculiarity in this plant from the regularly 
distichous, horizontal, and conduplicate foliage j 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 whole margins 
most beautifully ciliated. 

■ 

It is probable that the fructification of this plant will be found 
to resemble that of J. albicans ;— -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 (Hijpn., 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. y 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 j both too are smooth, not marked 
with reticulations, of which the interstices are sunk so as to form 
pits or hollows, as in Hook. Icete-virens and lucens.

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. iomentella, with 
which at first sight it may appear allied, and naturally ranks with 
J. appendiculata and J. nolilis of the Musci Exolici. 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.

tula parva, valvis ovatis, fuscis. 



This singular plant no one will hesitate to pronounce as nearly 
allied to J. juniper ina of Swartz. It has the same rigid texture 
and dotted appearance in the foliage, and the calyx is equally co- 
vered by leaves. 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.

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 Brynmjulaceum more than any other moss j 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 ea- 
lyptra, which I have never yet seen, although it does not bear much 
affinity to any of the other species of this varying genus. The 
nearest is perhaps G. astivum; in which* as well as in this plant, 
the perichaetium is highly worthy of remark ; 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. 
With N. cladorr hizans in point of size it has a greater resem- 
blance : but that plant has its leaves, though likewise destitute 
of nerve, of a different shape, not very correctly represented in 
Hedw. Sp. Muse, and the " rami apice radicante:

It is not easy at first sight, except by the decidedly sulcated

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 A. 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 0. longirostre, gracile, and their affinities.

So closely does this moss border upon the Sclotheimia squar- 
rosa 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 0. apicu- 
latvm 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 I can satisfy myself as to the real structure of the teeth, 
I shall place this species among the Orthotricha, where it will 
rank naturallv enough with 0. longipes, 0. gracile, 0. longi- 

differing however from all in the form

lena, 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- 
blance, 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. A - -

This is a plant the general structure of whose leaf is similar 
to that figured at Tab. XV. of this work (J. appendicular), 
but which comes from a very different part of the world, and is 
characterized by the undivided larger lobes of the leaf, never cut 
into pinnae-like divisions, and the quadrate and simply emargi- 
nate apex of the stipules. 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 leVes 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 lamellae or 
plates, totally unlike any thing I am acquainted with in vegeta- 
ble oeconomy, 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 y which I shall have occasion to 
publish.

The specimens here figured were communicated to my friend

gentleman whose ardent tbirst 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 lamellae, and by the 
shortness of the operculum. To these characters may be added 
the much narrower capsule, its less inclined direction, the nar- 
rower and more carnose leaves, and the much smaller size of the 
whole plant. Schwt^grichen 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- 
ties of P. undulatum, which is also a common plant in North 
America.

Among the Humboldtian mosses a considerable portion be-

The present species differs from most of the family in having a 
single nerve to the leaf, and the under side of the stem destitute 
of leaves, as in Anictangium torquatum.

the calyptra especially, which is beset with the paraphyses (of

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. Wbodsii: but this circumstance, taken in conjunction with the 
very different places of growth and some other peculiarities, has

Totally different at first sight as this Jungermannia may ap- 



ipl 

be minutely examined, the similarity between them is so great, 
that I hardly know whether I am warranted in making this a di- 
stinct 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 ; and lastly, the difference of 
texture, which is here composed of small distinct reticulations, 



ept 



cupressina 



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. Billardieri of Schwaegrichen ; his words being " J. caule 
erecto subramoso, foliis imbricatis ovatis acutis omni margine 
serratis, stipulis arcuatis dimidio minoribus j" — and I am the 
more inclined to think them one and the same plant, because 
M. La Billardiere 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.

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. CEderi.) 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 xvhich 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, 
vanishes upwards into the substance of the leaf, as in B. ithy- 

Its habit too resembles that of B. squarrosa of Turner,

on separating it from a genus in which A T . planifoUa> \vhich it so

also be observed, that it possesses, in common with the subject 
of the present plate, the membrane uniting together all the inte-

upright stems, bare of branches at the base, and thickly clothed 
above with bipinnated ones, which, as well as the leaves, are all 
regularly bifarious. Those of the main stems are strikingly like 
the leaves of N. pennatu, while those growing on the branches are 
nearly orbicular.

The present curious plant belongs to the same division of the 
genus as J. dilalata and J. Tamarisci; like them having the lo- 
bule of the leaf or auricle terminated, at least on one of its seg- 
ments, by a clubshaped 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. dilalata, 
and the rest of its affinities, and more nearly' resembles that of 
J.jimiperina, being altogether covered by leaf-like scales.

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 cristalus y of Turner. But a more careful inspec- 
tion, with a view to the drawing and description, satisfied me 
that t had fallen into an error; for not only are tbe 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 Jungermanma whose foliaceous branches, 
it I may thus express myself, arise from a trunk of a different or 
nrmer texture, as is the case in J.Jalellaia, J. trichomanis, and 
the present species, I fi„d the structure so very similar to that of 
many mdmduals of the f er n tribe, that I cannot do better than 
employ the same terms for different parts of tbe plant as are 
adopted by Willdenow, in his volume on the Ferns in tbe 



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 the same. 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 
longer, and very gradually acuminated >, and the latter character 
is remarkable in the perichaetial leaves.

entire leaves, (of which the texture is like that of the last-men-

the narrow nerve, exactly ovate capsule and subulate lid, will 
keep it distinct from any other with which I am acquainted.

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 I think that it is certainly 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 tlie genus Hypnum (H.basilaremd 
spinij'orme) 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 latter 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. spimforme 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 j 
so that it and H. mnhides 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

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. I have already 
noticed as being squamose, the stems of another Jungerniannia

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 scaly 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. Jim- 
briala, and its having the leaves and stipules narrower and 
more deeply cleft, with their segments recurved and their margins 

most beautifully ciliated.

At lAB. La, of this work is given a Jungcrmannia, (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 can afford marks of discrimination between the pre-

leaves of the former to a high power of the microseope, they will 



be 



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. Icevigatum 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, "foliorum dorsum undulatim dila- 
tatur 3 " 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. Icevigatum 
of Bridcl, which has leaves that are marginate and serrulate, and 
with which it can therefore have no affinity.

This is a small and obscure species, having no striking character

It is probably a Leskea, judging at least from its erect capsule 
which is so common in that genus y but although my specimens 
possess capsules with peristomes, yet this part is so minute and 
so extremely fragile that I am unable to satisfy myself as to the 
true structure of its inner teeth.

This remarkable plant, of which the specimens so liberally com-

J. Lyellii, J. hibernka, J. Jlabellata, and J. Hymenophyllum : 
differing from all, however, in the thicker margins of the fronds, 
and especially in the curiously lengthened extremities of the apices, 
which strike root into the ground, and are scarcely to be distin-

JUNGERMANNIA FALCATA.

Caulis procumbensj rigidus, nigro-fuscus, nudus. Rami erecti, 
flexuosi, rigidi, attenuati, dichotome divisi, versus apicem prae- 
cipue insigniter incurvati. Folia luride viridia, subnitida, bifa- 
riam imbricata, erecta, subopposita, cauli appressa, rotundata,

sus. &?/a3-4-pollicaris. Capsula ovata. 



The remarkable falciform branches of this plant and the great 
length of the fruitstalk, together with the insertion of the calyx 
and its texture, will at once distinguish this from every other 
known species. The leaves approach nearest to those of J. asple- 
nioides, as does the general habit of the plant ; but the fructifica- 
tion, 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 Jun germanm ce which I 
can only find to differ from the present, the one in its smaller size, 
tne 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. conjugaia 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 
base all round the stem, and thus the plant becomes perfoliate

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 
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.

JUNGERMANNIA GIGANTEA. 

Jungermannta caule adscendente fastigiatim raraoso, 
foliis bifariis disticbis rotundato-quadratis denticulato- 
ciliatis, calyce terminali oblongo, ore dilatato com- 
presso ciliato, seta breviuscula. (Tab. XCIII.) 



Hab. In sinu Dusky bay dicto, apud Novam Zeelandiam. 
D. Menzies, 1791. 



Caulis spithamaeus ad dodrantalem, basi repens, demum erectus, 
flexuosus, rigidus, niger, crassiusculus, sublignosus, ramosus, 
ramis fastigiatis patentibus. Folia plerumque arete imbricata, 
bifaria, disticha, patentia, nigro-viridia, rotundato-quadrata, 
denticulato-ciliata, margine inferne subintegerrimo. Substari- 
tia reticulata, areolis parvis, rotundatis. Perichcetialia reli- 
quorum similia, sed erecta, calvci appressa. Calyx termina- 
lis, bi-trilinearis, oblongus, basi cylindracea, apice valde com- 

■ 

pressa, ore ciliato. Seta calyce triplo longior. Capsula ob- 
longa, 4-valvis, intense fusca. 



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. asplenioides.

This very elegant plant may be considered to approach nearer 

to J. trilolata 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.

what is more remarkable still, its fructification on short horizon-

however, a very striking difference in the stipules, in the dilated 
posterior base of the present plant, and also in the colour : this
