If ral it (/ this is so with plants in ge most especially true of Ferns, tho complicated б } tender organisation of which bafle the most skilful and patient artist, who can only gi the best an imperfect sketch. of wha he supposes to be their more important features. And herein lies the great defect of all pictorial representations. ‘The draughtsman can do no more than delineate a part of what he sees; and whether he secs correctly what he delineates will at all times be а matter of doubt, especially where, as in natural history, minute accuracy is indispensable. But if minuto accu 1 importance in опе than another race of plants, it is most especially so among Ferns, in the distinctions of which the form of indentations, general outline, the exact manner in which repeated subdivision is effected, and most especially the distribution of veins scarcely visible to the naked eye, Мау the most important part. To express such fa ¡cts with the necessary accuracy, the art of a Talbot or a Daguerre was insufficient, nor could they be represented pictorially until Naront-Prrvnixe was brought to its present state of perfection. Attempts were long since made to obtain Botanical portraits by printing from the plants themselves, flattened and otherwise prepared for the purpose. Ву this means impressions of leaves were produced with some success, and even of small branches, Rude as the process was, and imperfect the result, it was nevertheless found that the figures thus procured were far more characteristic tha any which artists could produce, as was to be expected, indeed, from the absolute of the representations as far as they went. No one who had ever seen a Rose-leaf could fail to recognise its impression, or was likely to mistake it for that of an Ash-tree; and the more the impression was studied, the more did the truth of all its details carry conviction to the mind. The fault of the method consisted in its limited appli ion, and its incompleteness. ‘The process of the Imperial Printing Office at Vienna, to which the name of Nature-Printing has been happily applied, and to which the Work now offered to the public owes its origin, is a great improvement upon the old method, inasmuch as it represents not only general form with absolute accuracy, but also surface, hairs, veins, and other minuti of superficial structure by which plants are п details of their internal organisation. Moreover known irrespective of the hi an exact сор) copper of the part to be represe jeet as ted being employed by the printer, instead of so fragile an ol the plant itself, we obtain the means of multiplying copies to the same extent as in copperplate engraving ; and hence the method becomes suitable for purposes of publication. ‘The Germans have ady availed themselves of the art, and with considerable success Von Heufler has published a specimen of the Cryptogamous plants of the Valley of Arpasch,* some of the figures in which are admirable representat nature ; and other works are announced as having made their appearance, or being in preparation, in thé Austrian dominions. PREFACE Tt is in emulation of such continental efforts that the present Work has been prepared, with the keable evidence what differences really exist among the Ferns whic wild in Great Britain and Ireland. ‘These beautiful plants h i able to establish upon solid tion, and are nov so universally cultivated, that it has become most. 6 to expect from m riptions or imperfect engravings. It is true that Nature-Printing has its defects as well as it lvantages: it can only represent what lies upon the surface, and not the whole even of that, But, on the other hand, its accuracy is perfect as far as it goes ; and in the case of British Ferns it goes far nt tho forms of sori, these, orindusia, we must never enough for all practical purpose Iit fails to repr a Fern is Adiantum ге subjects of inquiry in the cab ye knows at a glance th D et The practi illus Veneris not by looking to the underside of its leaves, and ascertaining the form of its indusium or annulus, and the place occupied by the sori, but by its general manner of growth, the ramification of N its stipes, and the form of its leaflets all which Nature-Printing does sl ш cannot be applied, are sufficiently pointed ut by description al the present Work at least, are in no need of delineation.

It will be apparent, from the subordinate position assigned to them, that no botanical importance is claimed for most of the forms thus enumerated ; but the object of recording them has been two-fold In the first place they have been specially noticed for the purpose of affording aid to those Fe admirers, including not a few of the gentler sex and of high estate, who derive such agreeable recreation as that afforded by Natural History studies, in seeking and finding, in collecting, and in cultivati the species of Ferns, prolifie of varied forms, and which for the most part have to be sought amidst P р enchanting rural scenery, where both mind and body derive benefit from the pursuit, Such students of Nature have a right to whatever assistance they may draw from records like the present and it is for their special behoof that the varieties we have had occasion to notice have been mentioned under distinctive We believe, however at the long series of variations enumerated, have a bo ical significance and it is this, in the second place, which has led us to notice them with some particularity. They are not indeed, in many instances, objects which the general bo anist can attempt to keep separate under disti ¡ct names even as varieties ; those only which are most prominently placed having this importance claimed for them, But they are undoubtedly links in the chain of evidence which may direct him to the conclusion that species have a wider range of form, even within narrow geographical limits, than many nists are willin to admit, They may also teach him that the va ions of different plants of admitted specific rank, often serve to connect the individuals into a series so extended, that spec themselves thus become things of doubtful import, and of uncertain limit. "his lesson, again surely leads to the conclusion that species are mere groups of individuals associated by the Naturalist for his own convenience and that of others, just as genera are groups of the so called species collected to with the same end in view. ‘The fact that such closely allied series of forms which would ordin; be referrible to several species admitted to be distinct but which for this very reason cannot be absolutely defined, and the total failure of all attemp to explain practically what a speci int forcibly, if no bly, to the conclusion that Nature acknowl mly individuals, and that а species is а thing of man’s contrivance, and hence has only an artificial value Apart from this consideration, another obtrudes itself. Admitting the existence of species, whether AUTHOR'S PREFACE natural or artificial in character then, if in a small arca like th me much more often marked, and usually constant in character occur, the variations must b iid extensive numerous and marked, if the sp spread, as often happens, over widely separated portions of the globe, It may safely be concluded from this further view of the s that an infinity of species, founded on slight differences and often on the nero fact тірегі separation, are thus thrown open to doubt, or at once reduced to mere local variations. Many apparently genuine species also, thus become broken down and amalgamated һу the discovery of connecting varieties, it may be, at their antipodes, The number of apparently good species so-called which thus become disturbed by th atural difusion and variation le vegetable types from any intelligible centre of creation, which in that caso would bo a necessary assumption—and all such conjectures as to origin aro mere sumptions and an affectation of being wise above that whi itten —become a serious obstacle in the way of continuing to hold faith in th One object of enumerating tho varieties of British Ferns then, has been to prove, that so-called species do vary very much in our limited area ; and hence to draw the inferenco, sufficiently supported indeed by facts, that they vary much more when a wider range is taken into account; such a conclusion being clearly unfavourable to the multiplication of species. It is to be remembered that the variations often marked, and here spoken of, though sometimes slight, are neverthele the most part constant and appreciable; by no means frequently ranging as mere monstrosities, but even then for the п part permanent, and renewable from the spores—this latter fact probably affording incidental proof that spores themselves aro in reality buds, and not at all analogous to seeds, and sug 16 only remains here to acknowledge the much assistance which has been afforded us in the of our labours; all of which it is hoped п duly recorded.

P.vulgare bifidum. THE COMMON POLYPODY This Fern is easily cultivated, if light por 1, and the rhizomes aro kept on the surface of the soil. When unnaturally planted deeply, or in stiff retentive soil, it dwindles and often eventually perishes. Mr. Newman, apparently founding his opinion on the circumstance of its being frequently met with growing on pollard trees, considers it to be of parasitical habit. This circumstance would, however, give it only an epiphytal not a parasitic character; but as it is frequently found, fully as Vigorous, growing among porous earth and on sandstone, these are all probably mere accidental condi tions, the essential ones being constant moisture more or less in quantity, perfect drainage, and moderate shade. It even exists in health naturally with little or none of some of these conditions about it, as many an old wall bears evidence. It increases readily by dividing the bı шеніне rhizom There aro in this species many deviations from the typical form which has been already described; but they rather of importance to the horticultural enthusiast than to the tanist : except in as the latter may regard them as evidences of the manner in which, and the extent. to which, common species are known to vary; and may hence learn to appreciate rightly the less familiar differences which formation of the now are found to exist amongst exotie species, 16 is, however, chiefly for the i humerous class of Fern cultivators, most of whom take an interest in these variations, that they will be enumerated hereinafter under distinguishing appellations. Th at form of the Common Polypody which differs in the least degree, albeit constantly, from the state, has the ends of its lobes gradually tapering off to a narrow point, instead of being nearly ‘equal in width to the end, and there more or less blunt, A somewhat more diverse form has the points of th bes acute as in the Inst, but their margins are at the same time deeply notched, the notches forming a series of coarse double serraturos. ‘This stato has sometimes a tendency to bifureation at the tips of the lobes, and what is more remarkable, the sori are not unusually decidedly oblong, in which respect it deviates from the generic type. Another slightly varying form has the ends of some or all of the lobes di with the divisions divaricate, so that the lobes become more or less manifestly two- forked. Occasionally more than two points are developed to cach lobe, and we have thus an indication of the nature of the tasselled apices which are common in some other species of Ferns, Sometimes the fronds acquire breadth rather than length, assuming a broad outline ; and this is occasionally accompanied by various degrees of marginal division in the primary lobes, showing a transition towards the moro highly developed bipinnatifid varieties, semilaceram and cambricum. "The most simple condition of this abbreviated and widened form, in which the apices аге usually acute and the margins finely serrated, and which is almost or quite identical with the N American plant called P. virginianum, and nearly so with the Madeira plant called 2. eunariense in gardens, is apparently not common in this country, but. has been communicated from near Hereford by Dr. Allchin. Tt is when deeply erenato-lobate, that this type of variation approaches the more highly devel ped or compound forms above alluded to ; this, too, sometimes varies with oblong sori The Irish Polypody—P. vousane вюмп.дскпом—{зсе P Lare TL), of whieh type there appears to be some slight variations, and which, moreover, is not confined to Trelaud—has the fronds irregularly bipin- natifid, in this respect approaching the Welsh Polyp ly ; but the latter is more regularly and univer sally bipinnatifid, and is, likewise ways barren, whilst the former is more or less fertile. ‘The fronds are from a foot to а fi and a half long, elongate-ovate, pinnatifid, in the lower part almost pinnate. ‘The primary lobes are narrow and deeply serrate at the base and apex, deeply pinnatifid about the middle; the secondary lobes or lobules are linear, acute or bluntish, serrate 1 the frond, becoming shorter upwards, Along these lobules the vei om the principal midvein extend, and become branched, the branch dividing into from two to three venules; in the other parts, the veins are arranged similarly to those in luxuriant examples of the normal form. ‘The upper half of the frond is fertile, and in this t ones xtile portion the lobes are searcely subdivided, the upperm ır erenato-serrate ; the development of the lobules, and of the sori, are conse THE COMMON POLYPODY quently not generally coincident on the same parts.

One sorus was found still close the spore-cases little developed ; niform, and lay alongside the venule. In many of the smaller sori remains of an indusium and in two or three it was as nearly perfect as one may expect to find it, ‘The ша laciniated with fine projecting points. ‘The laciniatod margins are produced by the rupture of the cuticle, and the fine points are the cell-walls thereof. ‘The indusium is very tender, shrivels, and where r than in the spore-eases are numerous, is speedily concealed or perhaps displaced by them: it is sm: the other forms of Athyrium. These peculiarities seem to result from the rupture of the cuticle taking place ca in the progress of development of the sori ; but that it has the true indusium of an Athyrium Think cannot be further disputed.” Subsequently, Mr. Rylands writes :— Tho ‘indusia’ of alpestre are not, I think, confined to the imperfect sori, though after bursti ig they soon shrivel а the larger ones. I have compared it with A. Filir,famina molle, and though in t exture, position, and general character, there was littlo difference, I am compelled to admit that in the ease of alpestre the spore-cases seemed to lie within the proper cuticle of the frond, while the evidence of a distinct much clearer in molle. This supports your view to some extent; but, all things considered, is it suflicient to remove the plant from others so evidently its allies?” When so many of the sori—not only the majority, but all, with few exceptions, and those exceptions havi strongly marked imperfect ог. normal el aractors—really appear to be the round naked masses of Polypodium, we have no alternative, repudiating as we do the other grounds of sepa ation already adverted to, but to retain this plant in that genus, he Flexil Polypody—P. atpesmer rurxine—(Piare VIL, в. к) as communicated to us by Mr. Backhouse, is certainly a very distinct variety, and may b ner be species, the ing the view adopted by its only discoverer, Mr. Backhouse, who writes :—" Dissimilar as it is from P. alpestre, 1 shall continue doubtful of its specific dif nee if it does not turn up in other places.” It differs in being more slender and flaccid ; in having a much narrower outline, and consequently shorter pinne, with a ‚er of pinnules; in the form of the pis nules, which are oblong, narrowed below, sessile or adnate, and distantly toothed ; in the very short stipes, becoming obsolete in the cultivated plants ; and in a tendency to bear perfect sori at the base of the frond, while the apex is barren—the reverse of what usually happens. ‘The absence of stipes, which Mr. Newman icludes in his definition. is not constant, the wild specimens sent by Mr. Backhouse having a distinct stipes of about a couple of inches; this part, however, is always very short. ‘The fronds are from six or seven to twelve or hteen inches in length ; the pinnae, spreading or more or less deflexed, short, with about six or eight pairs of pinnules, ‘The sori are few, six or eight on a pinnule, usual y distinct.

In this latter, which was only sparingly fructified, the spore-eases appeared for the most part to be at slightly clongated rather than circular, indicating an affinity with Athyrium, and there was in some cases a peculiar membr ous development in the position of an indusium, again indicating THE ALPINE POLYPODY the frond, the more perfect (Sif with tho elated indusia of Athyrium, but at the base and apes of the 0 а wth, and truly polypodiokl.

THE COMMON PRICKLY SHIELD FERN P. aculeatum is very difficult to distinguish from its near ally Р. angulare, and yet, viewing the ugh every British forms, they appear to be distinct, Indeed, were it otherwise, a series varying thr gradation from pinnate to tripinnate must be united, and all hope of definin; a species would be at an end, While thus admitti ig the difficulty of diserim ig between some forms of these species, and without presuming to | y down any infallible rule for effecting t object, we may point out how they may with tolerable certainty be known from each other, presuming that in the applicati d appreciation of the distinguishing peculiarities some general knowledge of the plants is desirable P. aculeatum is ® stouter, more erect, and altogether more rigid plant than P. angulare, which is normally lax and herbaceous, equally large or even larger in its size, 2. P. aculeatum has its pinnules either confluent or decurrent, in which cases there is no difficulty whatever in distinguishing it; or, when the pinnules are distinct, as in the most perfect plants, they are wedge-shaped at the base, the anterior side being truncate, and the posterior obliquely incised in str: ight lines, the two lines describing an acute angle hy the apex of which they are attached to the rachis, In P. angulare the truncated anterior base has a moro curved outline, and the two lines of the base des right angle or an obtuse angle, at the apex of which is a distinct slender petiole, by which they are attached. 3. P. aculeatum has that is, attached at а point along the middle part of the venule; it is in fact nearer the base of the venule, ie, the point of furcation, than the apex, which is carried out to the margin of the pinnule, In P. angulare the fertile venule stops about midway across the pinnuld, and the sorus is commonly placed at or almost close to its apex. These peculiarities observed in connection with each other will serv to reduce tho dubious forms within very narrow limits indeed, at least, so far as British examples are concerned. ‘The portion rather below the mi ldle of the frond should be taken for examination ‘This is one of the most easily cultivated of all the larger hardy ferns. It prefers a loamy soil and Partial shade; and is increased readily by division. Being evergreen, its varieties are among the most de able of our native species for the decoration of shady walks and rockeries, in which latter situation especially, where the roots are generally well drained, provided the pl: effects of nts are not exposed to the ere drought and aro moderately shaded, they thrive admirably. It is also very manageable as a pot plant, and under any circumstances is ornamental in its character. ‘The smaller form, known as lobatum, is perhaps the most өш table for pot culture, on account of its size and the elegance of its fronds, which not uncommonly assume a very graceful lateral curve. The allied Р. Lonchitis, though a у vous looking and hardy plant in its native haunts, is seldom. seen to preserve its vigour under cultivation, at least in the neighbourhood of London, probably on account. of the impossibility of imitating the pure atmosphere of its native mountains. It certainly ut, its roots too should be prefers a damp atmosphere; and, provided the moisture is not sta; freely supplied ; they should fact be constantly moist with percolating moisture: and hence the necessity of a careful mechanic adjustment of the materials employed as compost, of which mellow m, gritty к nd, and small masses of some porous body, such as soft sandstone hould be the main edients. We have succoeded tolerably well by potting the pla ts very firmly in such a compost with x small proportion of peat added, the plants being kept under glass in a close cold shaded frame, but the removal of the plants for the winter to a cold greenhouse where the atmosphere was drier, led to the partial de of the fronds. The ame plants however on being enclosed within a hand where consequently the atmospheric moisture was more abundant and regular, gı ew vigorously : so that we have no doubt the requirements of this species are a well moistened but freely-drained soil and a damp atmosphere, which can only be secured in many cases by keeping the plants close under glass. ted by division, lateral crowns being seldom produced ; consequently, plants generally have to be obtained ‘om their native habitats. As it fructifies freely, they might be raised from the spores "There are various di es of development in this species, some of the most distinet of which have COMMON PRICKLY SHIELD FERN.

There is no ground whatever for the arbitrary selection, which Mr. Newman has made, of Z. Oreopteris, as the plant to bear Bory's name, to the exclusion о all the other species now usually associated with it: as he himself has deed shown by quoting Bory's subgeneric character, the application of which to this plant was an original error of observation, or at -ast the result of imperfect observations. Lastrea Oreopteris does, net, much less accord with Bory’s character than do th three Polypodies he associated with it. Presl was the fore quite justified when in 1836 he revived Bory's name (altering it to Lastrea) for a proposed group which included two of Bory's five species —Thelypteris and Oreopteris,—the others being Polypodium.

These, several names were judiciously distributed twenty years since—Aspidium to the netted-veined peltate Aspidiew ; Polystichum to the freo-veined peltate Aspidiew; and Lastrea to the free-veined reniform Aspidiew ; and no further change, at least for the British species, is now required When the species of Lastrea and Polystichum wero included under Aspidium they bore the English name of Shield Fern. It is however objectionable to use the same English name for different. genera and as the old namo of Shield Forn is more properly applied to the Polystichums, which are the most genuino Aspidia, wo have proposed in the Handbook of British Ferns, to use for the Lastreas, the equivalent name of Buckler Fern, which is here also adopted, ‘The common Male Fern cannot well be mistaken for any other native species. It has been formerly confounded with Z. cristata, but the two have no very close aflinity, and the only resemblance occurs in а form of Fili-mas, not common, in which the lower pinne are triangular. The Incised variety is in some respects like Z. rigida, but obviously different in many others ‘The Incised Male Fern—L. Рилхомдя 1xca—(Prare ХУ.) is altogether а larger and more striking plant than the normal form, more robust, averaging three or four feet, and sometimes reaching six feet in height, with a stipes of five or six inches. The fronds in unfolding liberate the point, which becomes nt Tike the curve of a shepherd's erook, as in the common plant; they are distinctly bipinnat lanceolate, not contracting abruptly near the apex. The pinn are elongate, tapering gradually to the apex. The pinnulos are somewhat less closely placed ; the basal ones notched, often deeply, on cach side their base, thus having a narrow attachment, elongately pyramidate-oblong, broadest at the base and with a narrowed though rounded apex ; the rest more broadly attached, and more equal in width the margins more or less deeply inciso-lobate, the lobes three to five-toothed. ‘The venation is more highly developed, thus: a vein is directed up the centre of each lobe, and this bears alternately several venules; but the sori are, notwithstanding, produced only on the anterior basal venule of ench faseicle, so that, as in the normal form, they are ranged in а single line on each side the midvein, commonly extending, however, much nearer to the apex of the pinmulo, "The indusium is here reniform in tho other, convex, entire, and persistent, ularly deformed monstrous leafy developments of this variety constitute the Aspidium depastum of Schkuhr. This variety is probably equally common with the type form, and appears as widely dispersed ; it is certainly found in the south and south-western, the midland and the northern counties of England; in Wales; in the east and south-west of Scotland ; in the Channel Isles; and about Kingstown, Dublin, Ireland, whence it has been sent to us by R.

O. Gray, It seems really to offer specific differences, in its constantly small size, the direction of the pinnw and pinnules, the peculiar distribution of the sori, the glandular inflected indusium, and in the important character of vernation In the process of unrolling its fronds, nothing like the shepherd's erook form is seen, but the rachis gradually unrols from the base to the apex. It is also reproduced from the spores, although that alone is not evidence of its distinctness, On the other hand, the gene 1 form of the parts, and of the sori and indusia, agree with diminutive examples of the Male Fern, The fresh fronds are fragrant, in consequence no doubt of the presence of numerous small glands on their surface ; the f ance having something of the sweetness of Mignonette he Abbreviated Male Fern—L, Еплх-мав arme viara—is one of the permanently smaller forms, and is probably specifically distinct ; though the Dwarf Male Fern has many characters in common with it and the two are perhaps forms of one subalpine species. The present is however a larger plant, with considerably larger, broader, and therefore coarser lookin pinnules, and although they are to some extent recurved, yet they are by no means so fully nor so constantly so, as in Z. pumila, This also has the fronds, at least while young, glandular and fragrant The Golden-scaled Male Fern—L. Frux-was pareacea—(Prare XVIL) differs from the normal form, most obviously in its colour which is a yellowish green, and in the abundance of the lustrous golden-tinted scales, which clothe its stipes and rachis, so densely that their rich colouring is always conspicuous, but most so on inspecting the back of the frond. ‘The same plant seems 1 that of Dr. Wallich in the East Indies; and by to have attracted Mr. Lowe's notice in Madeira its peculiar scaliness serves also to connect the common European Fiiz-mas, with some South American Ferns to which other names have been given.

Mr. Wollaston points out, that the rachis and midyeins are more or less tinged with purple, but this also occurs sometimes in inci. Тһе sori are often, if not always, smaller nd the indusium before maturity, and even when the spore-cases are ripening, has its margins very much inflected beneath them, so that, when reversed, it is seen to have the form of a little pouch, just in fact like that presented by one of the leaflets of Cheilanthes lendigera, In the common and incised forms of Filix-mas, the margin of the indusium is merely bent down straight, a little sloping outwards till it comes in contact with the surface of the pinnule, ‘The plant appears not uncommon, but its range is not fully known. It is, in part, from the Indian forms of this plant—forms in which we can detect no difference except the darker colour of their scales, and their somewhat larger growth—that Prof. Braun has constituted his genus Dichasium, which is characterised by having *biseutelloid" indusia, which are indusia of roundish outline with a sinus extending upwards beyond the centre, so that the lobes look like two flaps We have ascertained from a careful examination of Dr. Wallich’s specimens that this appearance of the indusia is merely the result of age.

Probably in old plants the viviparous character will be more abundantly developed, 5. dichotoma (№). This is a multifid variation of the normal Filir-mas, exact corresponding in its peculiarities with the variety mudtifida, already noticed, in having the apex of the frond and of all or the greater part of the pinnw two-cleft or many-cleft, the pinnæ ocensi nally depauporated.

It appears to be comm to be in fact one of the two Та y forms into which the species is commonly developed, the characteristics of the two being sometimes united in one plant. The Rev. W. A. Leighton appears to have first noticed the peculiar lobing ; his specimens athered twenty years since are from Bomere and desea. We have also seen Sutton in Shropshire, and from А) Callende peeimens from Ballyvaughan in Ireland, in Scotland, Bedale in Yorkshire, Black Park in Bucks, Maidstone and Cobham in Kent, Albury in Surrey, Epping in Essex, Lynn in Norfolk ; as well as from Jersey and Guernsey 9. producta (М. This is а very striking variety, somewhat analogous to incisa, being like it a large growing plant, with fronds at least three feet long and ten inches broad, and also n mbling it the divided condition of the pinnules, which are however much more deeply divided. The frond is lanceolate ; the lowest pair of pinne two inches and a half long, triangular a the next are gular elo nearly two inehes across the bi more than four inches long, tria se, gradually per part of the frond, though narrower at the yg to a sharp elongated. point ; those in the w го also triangular elongate, the base being broadest, thi igh in the uppermost the sides become more nearly pa allel. "The pinnules throughout are elongated, deeply pinnatifid, and narrow upwards to the apex, their outline being that of a narrow cone or pyramid; this, together with the deep and conspicuous lobing, gives to the plant a very distinct appearance mules, which are cut down more than half way to the midrib, have an attachment so narrow as to resemble a mere winged petiole ; the rest, half way up the pinnas though adnate are attached by less than their whole width. "The lobes of the pinnules are obscurely serrated at the end. "The sori are confined to the upper 1 central than the basal portion of th third of the frond; and on the only frond we have seen have a manifest tendency to occupy rather the pinnules: that is, they are distant from the base on those pinnules which occupy the lower half of the fertile pinna. This variety was found by the Rev. W. A. Leighton, at Wrekin, in Shropshire 10, triangularis (ML). This form belongs to the incisa group, but has something of the aspect of FERN THE MAUI w sti ereetish fronds, and especially for the unequally EEEREN socially ; these having—as indeed the Lastrea cristata, bein triangular outline of a few of the lower pinnae, the lowest pair esp pulosa than that which usually occurs in whole frond has—much more the outline met with in Z. sp ish and all but the bas а the enlarged posterior basal lobe, which occurs in 1 ones adnate or decurrent; they are L.

THE CRESTED BUCKLER F RN. treated all three as forms of one species; and that they have a clo natural affinity which separates them from the forms of Z. dilatata, we have no doubt whatever, however similar to the latter, in some cases, may be the degree and mode of division in the fronds. "Thei inity is evidenced by marks far more important t an those to be derived from such inconstant characters as are the outline or division of the fronds: namely, by the creeping des, by the sparse and pallid broad appressed scales, and у 1 Г by the erect narrow fronds, and entire indusia, in all which they agree. In these points they differ more or less obviously, and in the case of the first-named absolutely, from the dilatata group. Without at all disturbing the convietion which led us to regard these plants as varieties of one species, we however propose here, in deference to the more commonly received opinion, to treat of Z. spinulosa separately The La: rea uliginosa of Newman (Prate ХХ.) we must still regard as a variety of L., eristata, the only marked difference, in truth, being that its earlier fertile fronds have the pinnules more asly lobed and toothed acute, and more eonspiew and that the d poney in size between the anterior and posterior basal pinnules is a degree more manifest. It has a stout decumbent caudex, and erect lincar-lanccolate fronds, two to four feet high, and bipinnate at the base of the pinna. Three kinds of fronds are borne by the plants, but they are not all simultaneous in their appearance, nor constantly produced; and though different they are not strikingly dissimilar, like the barren and fertile fronds of some other Ferns, The enrly fronds of the st nger crowns are fertile, and with them sometimes but теп, the latter not always appear others which are smaller and b m produced from small lateral crowns, but also so is from the same crown which produces the fertile ones; whilst later in the season other fronds with bı ader and blunter pinnules are borne, these being sometimes fertile, sometimes barren, Thus, the early barren fronds are small, spreading, pinnate, with decurrent oblong obtuse pinnules, and resemble small barren fronds of istata, ‘The summer fronds are also eristata-like large, with decurrent oblong obtuse pinnules, and very frequently fertile, ‘The fertile fronds produced in spring are more like spinulosa ; they grow quite erect, and are linear-lanceolate, bipinnate, the basal pinnules distinct, all the pinnae stalked, and set on so that their upper surface is turned towards the point of the frond.

"There are two versions of the specifie name of this plant in use a British botanists- spinosa and spinulosa. We advisedly use the latter. Тһе former has been revived by recent authors, on the grounds that Roth who employed itin Flora Germanica (1800), was the first to correctly define the plant from its ally Z. dilatata, and that Müller in the Flora Danica has “misprinted” spinulosa for Weiss’ name of spinosa, and under it figured the plant we now call Z. eristata, Weiss’ name Polypodium Filizfamina var, spinosa, as that of a variety merely, and altogether so incorrect, has no claim to notice Müller describes, but witho name, and very well figures, two рїшше of Z. spinnlosa in the Flora Pridvichsdalina (1767), and his later figure in Flora Danica (1777), where he names it Polypodium spinulosum, is an exact representation of our Z. spinulosa, and not of 2. cristata, We therefore llow the neither subscribe to the assumption that Müllers name is a misprint, nor can wo лос over Roth. a of sum as defined by Swartz in his Synopsis Filicum (p. 420) is the plant of jade on behalf of Weiss’ name; while Müller has by many years the preced Equally, as we believe, го those writers in error, who deny that this plant is the Zastrea spinul Presl.

They are bipinnate above, tripinnate below ; the pinne ascending and twisted, so as to form nearly a horizontal plane, laneeolate-ovate, the longest nearly six inches long, and about two inches broad just above the base ; pinnules lanceolate-ovate, or pyramidately ovate, acute, reraging nearly an inch in length over the greater part of the frond, the posterior ones on the lower pinnae long st, those of the lowest pinnse being an inch and three-quarters long ; the lower ked, the rest successively decurrent, adnate, confluent. ‘The pinnules are pinnatifid almost down to the midvein ; their lobes obloı adnate, incised or toothed, the serratures all tipped by a bristle-like point. Tho stipes varies from about one-third to one-half the entire length of the frond, and is clothed sparingly upwards, more thickly near the base, with ovate bhuntish, and ovate-lanceolate pointed scales, which are generally of a pale brown, scarcely tawny, some having and others wanti darker central streak, many of them, as seen in the grow plant, becoming a good deal appressed to the stipes, whilst a few remain spreading; but this appears to be far less obvious when dried.

The latter is certainly not identical with the Dean Forest and Epping plants, but approaches them closely in some respects, differing chiefly in its laxer habit, and less elongated fronds, and in the presence of more nume pointed lanceolate and dark-centred scales among the br ог ones on the stipes. We have gathered another glandular Fern at Hampstead, Middlesex, somewhat different, especially in the scales, which are lon narrow, and in the more obtusely ovate form the pinnules. This latter, with that from Barnes, supplies the connecting links between glandulosa and dilatata ; the most ordinary looking forms of the latter being moreover sometimes quite glandular Besides the varieties already mentioned, which we consider the most distinct and important, thero are many other, indeed almost endless, modifications of this Fern, many of which, however, we believe to bo permanent forms, although they have not all been proved by cultivation. ‘The following is a brief summary of the various forms which have come under our observation 1. multifida (W.). Mr. Wollaston describes this as having the rachis divided very low down, so that, in fact, two fronds are, as it were, borne on one stipes. 16 is, however, rarely that more than one or two fronds on a plant are affected, and the variation is not constant. tanacetifolia (ML).

The largest plants seldom exceed a foot in height. Some of tho forms have been referred to collina, but it diers from that in іш abundant glands, and in ia pallid fimbriated scales. The Arran, Devon, and Isle of Man forms have their scales somewhat less fimbriated than the others. A small ovate form, agreeing with this in the scale and in the glands found in Glen Croe, Argyleshire, is tripinnate at the base, and has the pinnutes much smaller than usual, giving it a somewhat different aspect, and it is probably a permanent departure from thie type of variatio 9. collina (Хетта), This is a narrow ese form, from ono to two fect high, with the fronds varying from narrow ovate elongated at the point, so as to become ovato-lanceolate, to narrow oblong-lanecolata. ‘The pinnules are bluntly-oblong, with coarse acuminately-aristate teeth.

This very diminutive plant was found by a gardener named Schofield, near Buxton, Derbyshire, a few years since, and has since retained its peculiarities under cultivation, It is uncertain whether it should be referred to Æ. dilatata or L. spinulosa, and its tendency to a creeping habit of growth, as well as its concolorous scales, rather lead to the inference that it belongs to the latter ; but itis yet altogether too diminutive, and too litle known to admit of the question being decided.

THE LADY FERN Cauder stout, erect or decumbent, sometimes elongated and trunk-like, often tufted, scaly at the crown. Seales lanceolate or ovate-lanceolate, dark brown, sometimes almost black. Fidres strong, ‘kish, branched, the younger parts tomentose ‘Stipes terminal, and adherent to the caudex, from about one-third to one-fourth the entire length of the frond, pale green or dull purplish red, stoutish, much thick ned and assuming a kind of spindle-shape just above the base and considerably reduced in size at the extreme base, scaly ; seales numerous on the lower part, lanceolate linear, dark-coloured, varying from dark reddish brown to almost b k, fewer and narrower on the upper part, often contorted, Rachis furnished sparingly with small narrow melled in front, rounded behind. deciduous senles, cha Vernation eireinate. In the partially developed fronds the apex becomes liberated and bent down wards in a curve like that of a shepherd's crook. Froud very variable in size, outline, and division, herbaceous, usually of a bright tender green, егесі spreading, or drooping. In the form we have figured (which is one of the most compound states of the incisa type) two to three feet high, and from nin inches to a foot broad ; but often met with mature from one to two fect high, and from threo to six inches broad, and not unfrequently пе ly or quite five feet in height, with the longest pinnæ measuring ten inches. ‘The outline is lanceolate, sometimes v broad, sometimes narrow ; the less developed forms scarcely bipinnate, the pinnules being connected by the winged rachis, the more highly developed forms almost or quite tripinnate, the pinnules being distinct, and divided almost, or quite, to the midvein. Pinner numerous, opposite or alternate, more distant below, and often deflexed ; sometimes approximate, sometimes distant above ; linear-oblong, broadest at the base, gradually narrowing to а point, pinnate. Pinnules oblong, or ovate-laiceolate, obtuse or acute ; sessile with a broad attachment, decurrent and confluent at the base, or with a very short narrowed stalk-like attachment ; pinnatifd with shallow 2-3-toothed lobes at the base, and simple teeth towards the apex, or deeply pinnatifid throughout, with the lobes variously toothed—the teeth sometimes confined to the apices of the lobes, but in the more compound forms extending along their sides ; the teeth are usu short and blunt-pointed, but somet nes narrowed and len; hened, though never normally bristle-pointed. ‘The pinnules are sometimes merely patent, but frequently form a right angle with the secondary rachis and they are sometimes flat, the teeth lying in the same plane they become convex from the incurving of the teeth over the sori. In some forms there is no appreciable difference in the proportionate size of the lobes, but in others the lowest anterior lobe is considerably longer, giving an aurieulate appearance to the pinnules, and forming a conspicuous line on each side the rachis of the pinna: ion of the pinnules in the less divided forms consisting of a flexuous midvein, producing alternate veins of which the lower are forked, with a venule directed into each tooth, and the upper are simple, directed into the simple teeth at the apex of the pinnules ; in these the anterior venule of cach fascicle bears the sorus along its anterior side. When the pinnules are more divided, the veins are pinnately branched, several alternate venules being produced, the number corresponding with the number of teeth ; the anterior venule is here also soriferous, so that a line of sori are produced on each side the midvein, but in addition s me of the other venules of the lower lobes bear sori. When the pinnules become very deeply divi fe J, as in the most compound states of the plant, each of the veins produces sever е venules, the sori then forming two lines along the lobes. The veins а d venules terminate in a very slight attenuated point, just within the apex of the tooth, towards which they are directed.

In the very much divided varieties, this curved form of sorus is more frequent; and sometimes it is өтеп moro abundant than the simple oblong form. In this latter stato, the fructiication may be readily mistaken for that of ‘or Jess confluent by the spreading а Lastrea.

Though related on the one ists, it is at once dis hand to Asplenium, and referred to that genus by many talented bo from all the British 4 ms by its herbaceous texture, its annual fronds, and its whole habit, as well m splen as by the curved or arcuate sori, On the other hand, these sori connect it in some degree with Lastrea, and it was no doubt the examination of specimens with advanced fructifications of this form which led toits being associated, as it was formerly, with Aspidium ; but neither is it properly referrible to the Aspidice at all, nor is the plant sufficiently like any species of Zastrea to be mistaken for one of them. ‘The genus Athyrium, to which it is referred, is nevertheless one of doubtful character: not on the ground stated by Mr. Newman—that Roth's typical species is Asplenium fontanum, and that we have по right to restr 4 the genus to the “Filix-fæmina or abnormal group,” because that would be a palpable perversion of tho authors meaning; for the fact of Asplenium fontanum occurring first in Roth's ‘enumeration of the species, does not constitute it the type of the genus, Ъ is clearly on account of its x the smallest and the simplest of the forms he proposed to brin together ; Roth, moreover, in his vio character, expressly states of the indusium “margine laciniato-fimbriatum,” which character belongs specially to the Filix-foom » group, and does not well apply to A. fontanum. There need be no hesitation therefore about restricting Roth's Athyrium within the limits to which he himself points, and. thus identi p. Tt is by taking a wide ш it with the Filix-fæmina g d more comprehensive view that the genus becomes doubtful. Both Presl and Fée unite Allantodia and Athyrium under the latter namo, and characterise thé oup mainly by the short oblong gibbous sori, and vaulted indus but these marks pass i nnsibly into those of Asplenium ; while the character al ded by the fringed indusia, on which Rot seems partly to have relied, is too trivial for the purpose of generie definition ‘The remaining character, that of the curved arcuate wse-shoe-shaped sori, is certainly foreign to Agi and indicates, as we have alread towards Lastrea, Tt is on this ground that we adopt the genus, from which the straight-fruited Allantodias should assuredly be ovod to Asplenium.

Its habit co ds exactly with the usual form of the plant; but it differs in having the apices of the frond, pinnae, and (in well-grown plants) the pinnules most exquisitely tasselled or divided into a lash of branches. "he tips of the pinn are in fact many times dichotomous, with the apices dilated nd incised. It belongs to the rhaticum group. Mr. Wollaston suggests, with a view to uniformity in the names of corresponding varieties, that this ought to be called cristatum on account of its similarity to the crested f m of the Male Fern ; but it seems imp without continually changing the names in u at this uniformity, so that Fern-cultivators should adopt the rule which botanists have established on this point, and avoid mere changes, Our plate of this ty necessarily represents a small specimen ; when lange and at the same time well grown, it is far handsomer. This form was Ireland, by Mr. D.

A cent mass of this plant, cultivated by Dr. Young, can be seareely less than a foot in diameter with fronds eight or ten inches long. ‘This plant is not much given to variation, Mr. Wollaston notices a variety, multifidum, in which the fronds are occasionally bifid or multifid at the apex; this state is not uncommon, but it is also not permanent, Im d plants having this tendency sometimes produce a few of the pinne unusually Mr. Wollaston proposes for another supposed variety, of dubious origin, the ше of proliferum. ‘This interesting plant, which has been known to us since 1851, is so remarkably distinct, that were it not for the ob ity of its history, we should, without any hesitation, claim for it specific rank ‘Though most like A. fontanum of our British species, it is in quite unlike that plant in several of. its characters. We do not recognise it in any published descriptions, nor can we find any specimens to which we can refer i in Sir W. J. Hooker's magnificent collection. The fronds we received in 1851 were from the gardens at Pepor-Harrow Park, Surrey. Tt has since bgen exhibited at the metropolitan fates by Mr. Parker, nurseryman, of Hornsey, who, we bel хе, holds the stock of it, and whose plants were obtained from Mr. Williams, gardener to С. B. Warner, Esq, of Hoddesdon, Mr. Williams reports that about six years since he received it, as A. viride, from a gardener, whose friend had found it in Scotland, and sent three plants. This person, whose name was Filden, it appears died soon after the occurrence. Compared with A. fontanum, the fronds are longer and narrower in proportion, being seven or eight inches high, and not more than three-fourths of an inch wide. ‘They have а dark brown rachis throug! out, which is not distinctly winged, as in fontanum, although there is a slight decurrent line at the upper angles between the pino ; the outline is different, being equal and almost linear, not broader ET and the fronds are proliferous. Mr. Wollaston remarks, that “its having been associated with upwards ; the wer pinnw are scarcely more distant than the rest, and they are ieted in a remarkable manner, as well as much less divided ; the habit of growth is spreading, eiride, and partaking so much of the aspect of that species as to have deceived some of our best P " pteridologists, is at least cireumstantial evidence of its British origin.

For outdoor rockwork modera well adapted on account of its shining ever appearance ; and if p ted in porous soil among stones on a north aspect, it will generally flourish, It does not like a smoky confined situation, and is therefor «s frequently seen in a thriving stato in town gardens. It may be increased by division ‘The Obtuse Black Spleenwort—A. Avtayrus-sicnum onrosew —(Ртлтк XXXVI, C, D) should perhaps be considered rather as a less developed condition than as a variety, it being united by various gradations with the more deve 4 plant, which we have taken as the representative of the species; nevertheless, its extreme states seem to claim especial notice. It is a comparatively small nd dwarf plant, and assumes an ovate rather than a angular outline, Some specimens are not more than two inches high, and others very marked in character are six or eight inches high. ‘The smaller specimens are barely bipinnate, the pinn short and bluntly triangular, the pinnules roundish obovate, and very indistinctly toothed. ‘The larger examples are tripinnate, with their primary and secondary pinnules corresponding with the pinna» and pinnules of the small specimens. Tt is probably not uncommon, specimens from the three kingdoms being before us. ‘The Acute Spleenwort—A. Avraxtew-xionew acorem—(Prare XXXVIL) is a more distinct plant, and might perhaps be separated from A. Adiantum-nigram without much inconvenience or error ‘There are, however, connecting links, which, in a botanieal point of view, seem to indicate too close an aflinity to favour the separation of the two, and suggest rather the idea that the one is the extreme development of the other, ‘The texture of the plant is firmer and less coriaceous than the us states of A. Adiantum-nigrum, but some forms of the latter are undistinguishable in this respect. "Ше caudex is short, thick, and tufted, like that of A. Adiantum-nigrum, with which it also agrees in being furnished at the crown and on the base of the stipes with cellulosely reticulated scales, lanceolate below and ending in a hair-like point, as well as having elongated dark purplish brown stipes. The fronds in the Irish specimens vary from about six to eighteen inches in length including the stipes, are from about two and a half to seven or eight inches across the of the leafy portion; in THE BLACK MAIDENHAIR SPLEENWORT A very fino example before us, the leafy part is eight inches d, the stipes nine inches They are quite smooth, and in outline are sometimes deltoid, or perhaps more correctly pentangular, the apices of the lowest posterior pinnules forming additional angles ; sometimes ovate with the point much attenuated, Full-sized examples of the latter, and a rather small frond of the former state, are shown in our Plate, The smaller might be supposed to indicate a le unt of the dition of the plant, but we are scareely prepared this explanation, on ceeurrence of equally. small fronds in which the pentangular outline is preserved, while again the ovate fronds are often abundantly fertile; and we would rather suggest that it is an instance of that profusion of form in Nature which mocks at our specific definitions, In the larger fronds, which are most quadripinnate, the pinnas, especially the lowest which is also the largest, are of the same subdeltoid outline as the frond itself, excepting that as the pinnules are alternate and not opp the lower pair of pinnae are, | gree of obliquity almost producing a trapeziform outline The apices of the pinnas as well ules, are caudate, with a few f the frond, and generally of the p the mewhat obliquely ovate attenuate, and their divisi nte mdary pinmules, are lanceolate, deeply pinnatifid at a very a wer of which aro about three-toothed, the upper bifid at their points, narrow and very acute these lobes as well as the simple teeth at the apex of the pinnule itself being "The pinnae towards the apex of the frond, and the pinnules towards the apices of the pinne, become gradually narrower than the basal ones ove, until they both become reduced to linear lanceolate sharply toothed lobes, and these gradually merge into the simple linear teeth of the caudate extremities. А similar mode of division, but on a smaller scale, obtains in the smaller forms, The ing only tripinnate, and the secondary pinnules narrower, and less deeply lobe veins, though slender, are very distinct ; they consist of а series of furcations, that is to say, the vein which re pr former simpl sents the midvein of the pinnules forks below each of the lobes or teeth, and the venule thus › duced proceeds along the tooth or lobe until it nearly reaches the apex, being in the case of the and in the ease of the latter again forked o r twice, according as there may be tw three apical teeth, No one who has ob wainted with our хуей the venation in this plant, and is ac British Asplenica, can fail to notice the similarity in form and division and in the condition of the veins that exists between some of the pinnules of this plant, specially the shorter and broader ones of the less divided fronds, and some fronds of 4. septentrionale.

Under this name are included those forms in which large size and laxity of habit are coincident with an elo tion of the parts, and a thin though firm texture of the fronds, such forms having often been wrongly associ fed with acutum. From that variety they differ in their more elongated and less compound fronds, and in the greater breadth of their ultimate divisions, ‘The pinna and the fronds are caudate, but there are no linear segments of the pinmules, It seems to bear about the same degree of relation the normal state as obtusum, but in an opposite direction, and we enumerate it as a variety merely in order to point out the steps by which the more usual state of the pproaches the distinet-looking acu form.

This form in its texture and the acuteness of its divisions has a good deal of resemblance to the true acutum, but it recedes from it even more than the last in the outline of the frond, which tho all is rather narrow and elongated, with a tendeney to diminution rather than enlargement of the lower pinne. The pinng are short, very oblique from the еп rgement of the basal anterior pinnule, the latter bei 'g more distinct and distant than the remainder, which become a good deal confluent; the teeth are deep, narrow, and conspicuously acute.

This, like acutum, is almost or even quite quadripinnate, and may be briefly described as resembling that variety in the form of its fronds and pinn, and even pinnules, but the ultimate parts though narrow are blunt as if rounded off, not acute as in that, and the texture is reover, although small and comparatively narrow, are not so much narrowed as in acutum, and the absence of linear segments, and the bluntness of the few teeth which are apparent, readily distinguish this plant from that. We have received it from the Rev J. M. Chanter, who found it at Manaton, in Devonshire 9. acutum (Bory). This, which has been already fully described, differs in its moi с subdivided fronds, in which the deltoid modo of growth is usually strongly developed, in its thinner and papery texture, and in the presence throughout of linear acute segi ients and teeth, As to its distinctness, the preceding enumeration of varieties or forms occurring in this country s s that in comp simulated by decomp um, in texture by oxyphyllum especially, and by intermedium in a considerable degree ; and in the presence of linear segments or teeth, both by aryphyllum, in which the teeth th sharp are short, and by Jissum, in which latter the narrow n arginal divisio is are, perhaps, rather abnormal developments of the teeth, than normally narrow divisions of tho pinnules These points of resemblance, however, and the occurrence of other foreign intermediate states, have determined us in retaining acutum as а variety of A.

The pinnas are undulato-crenate, slightly lobate, with blunt teeth, The venules appear more clavate than usual. It is a rare form, and was found in 1850 by Mr, Wollaston, in Dorse shire ; since that time it has retained its character. A similar plant has been sent to us from Totnes, 4. trapeziforme (Clapham). The fronds of this variety are r t and leathery, the pinnae nearly trapeziform, imbricate, and erenulate. Tt was found by Mr. Clapham, at Scarborough, Yorkshire, and is a permanent form. 5. crenatum (М). This is remarkable for its short, obtuse, oblique, trapeziform pinn rownd the mar in with small but deep roundish crenatures. It occurs in a stone quarry, near Warrington, and has been communicated by Mr. T. G, Rylands. 6. cuneatum (М). T s is peculiar from the absence of the aurieuliform projection usual at 0 anterior base, the base of the pinnw being truly wedge-shaped ; the pi aro oblong, with deep sharp uneven serratures. It was found by Dr. Allchin at Black Head, Clare, Irel: 7. microdon (М), This is the most remarkable variety with whi we are acquainted, and but for a repugnanee to add to the number of dubious species, we should be tempted to consider it distinct, Its chief points of discrepancy are its sub-membranaccous texture, its undulately-lobed pinnas its denticulated margi д, which id small patent apiculated teeth ; and. small dispersed disposition follow rather the margin than the midrib, and in their shortness and paucity of spore-ca bear no comparison with those of any British Asplenium at all resembling the present plant. It resembles A, marinum its scaly crown, pinnate fronds, and winged rachis, It is not so much divided as A. Zanesolatum, or A. oboratum, from which also it differs in other respects.

This form has the acute elongated pinna of acutum, with somewhat the lobing of sub-bipinnatem, or else is narrow and strongly auriculate; the рішше resembling those of the Australian A. caudatum, or the West Indian A. auritum.

In country rockeries it succeeds when such precautions are taken, but in town gardens it requires shelter, and then even more caro is necessary to guard against excess of moisture In endeavouring to account for the difficulties which occur in cultivating Ferns such as the present, which sometimes prove to be rather shy growers under artifical treatment, the natural conditions under which the plant occurs should be well studied. Hore is a species abundant enough naturally which oftentimes refuses to maintain its natural vigour under cultivation ; and why? In most cases it will bo found that there is something wrong at the foundation ; the roots are suffering. Indeed, this appears to be the principal source of failure in cultivating the Common Maidenhair Spleenwort, The plant naturally grows on the perpendicular face of walls or rocks, inserting its roots into the erevices d fissures where it finds enough nourishment; or even when growing on banks the soil is generally of an open sandy texture, so that water docs not stagnate. It should not, therefore, be planted in lange masses of soil retentive of moisture ; the crown should be elevated between fragments of stone ; the pots should have an extra amount of drainage; and finally, sand, fine broken brick, broken sandstone, or the rubbly portions of mortar from old buildings, should be freely used. In short, above that portion which is kept free for drainage, the pot should be filled up with coarse pieces of brick, rock, or mortar, and the interstices only filled with finer soil, in which the same ingredients, mixed with sandy loam, should predominate, This mode of potting is suitable especially for the present species, the Wall Rue, and the Ceterach.

Water must be applied cautiously; the crowns or cen growth should not be wetted, and the fronds them are the better for being kept dry, although an occasional syringing, if necessary to cleanse them, will not be found injurious, provided they are afterwards allowed to dry. ‘The more successful instances we have seen of the cultivation of this Fern, were in cases in which the atmosphere of the greenhouse was kept rather drier than is usual in Fern it tho natural habit of the houses; and this is just w o expect plant would lead one Sinco writing the а +, Mr, Wollaston, who is a very successful grower of Ferns, has favoured us with the following memo ‚da of his experience with this species, He says it succeeds best with him planted in sandy loam, with a very slight admixture of perfectly decayed leaf-mould, over plenty of drainage, without moss above it, with a free use of water, and free ventilation. “Finding it difficult to he writes, “I t d it in the following way.

That planted in ndy loam did best, very perceptibly, and that in sandy peat did worst; that in pure leaf mould was bad also, Until lately very little variation had been observed in this species; now, however, several m: varieties are known, and they, for the most part, seem to have the quality of constancy 1. dichotomum (Wo. 1 his resembles the normal form in every respect except the dichotomous division of the apex of the frond, Tt is occasionally met with, but is not constant, 2. difurewm (W.) is a neat and pretty variety, differing in having the apical lobe frequently enlarged. amd always doubly or {геу fureate.

Iis early history is lost, but some seedling plants made their appearance in a mass of Hymenophyllum unilaterale sent to Mrs. Delves, of Tunbridge Wells, Kent, from the Glasgow Botanie Gi ind in 1853, by Dr. Allchin, in Clare, in Ireland, and 6. depauperatum (W.).

At home on the mountain sides of the north this delicate species does not bear so well as others the atmosphere of lowland cities, Hence, except in favourable localities not affected by smoke, the plant will not bear exposure. It is generally found necessary to cultivate it under lass, а cold frame occasionally ventilated, and with the atmosphere moderately moist, being most suitable for it, "he soil should be of a rocky nature, and no stagnant water should be suffered to remain about it. It may be increased by division, For pot culture in a moist shad icenhouse or frame, a soil composed of equal parts of loam, peat, sand, and sandstone rock broken up into lumps of one or two inches diameter, should be employed, and the pots must be w ell drained, because, as it is necessary that the roots should be kept. moist, provision must, be made for the free pass of the water applied, во that it may not stagnate. ‘The proportion of rocky material, for which soft broken brick is a passable substitute, may be even increased with advant igo, the object b 1g to provide for the draining of the moisture away from. the crowns, whilst it laves the absorbing fibres of the roots. In outdoo ockeries such species as the present would be benefited by the use of a kind of bell of шщ like а moist atmosphere about the plants during the arid glass provided with a vent at the top, which may either bo opened or closed at pleasure. The u such a glass would be to retain somethi summer months, and to shield the crowns from exe s of wet in winter. If the aperture, or apertures, were but of moderate size both these objects would be secured without ev closing the glass, and. thus risking another evil which follows mo ntain plants when brought under artificial culture away from their pure and airy habitats—that of өші cation from too close confinement ‘The varieties of this Fern are not numerous.

(М), This is а distinct and constant form, cultivated by Mr, A. Tait, of Edinburgh, It is peculiar in its short blunt ovate narrowly tly stalked pinnules, which are deeply separated into distinet oblong lobes, almost pinnules, and these are notehed with small even teeth, which are very apparent, The spores are echinate. The colour of the fronds is a dark green, 3. dentata (Dickson). There are some cultivated forms referable to this variety that aro constant, though it is probable that accidentally blunt pinnuled fronds of other forms aro sometimes associated with it in the herbarium, and hence it is often looked on as inconstant, The features of the true plants эге, small size (four to eight inches long), and confluent pinnules, so that the narrow fronds are sometimes scarcely bipinnate ; these pinnules are blunt-oblong, simply blunt-toothed, or obscurely blunt-lobed, and with the sori placed near their margi d forms, having the Somewhat larger and more ply same aspect, aro met with, and through these it gradually merges into obusa, and the normal form.

The Jour is uniformly a decp bright green. In the more highly developed of the fortile fronds the lobes of the pinnules, though still blunt, are more distinct, and they have then blunt inconspicuo teeth. The sori are situated very near the margin. The pinna are twisted more or less from the plane of the frond, as occurs in some gree in dentata, from which, with the deflexion of the pinne and the frequent confluence of the pinnules, results a pecular aspect, һу which this variety is known at first sight. The spores are or tubereulate, not echinato-tubereulate as in the other varieties, a fact, we believe, first pointed out by Mr, Wollaston, The plant was first found by Dr. Dickie on dripping rocks in a cave at Cove, near Aberdeen, and it has since been gathered in the same place by several botanists, and by Dr. Balfour, near Dunkeld.

The plants average about a couple of inches in height, and rarely exceed three inches. Tt is an extremely interesting plant; and we think may fairly be allowed to remain separate from O, eulgatim—unless indeed in the Vegetal t adopt the rule of combining under the name of a species a lengthened series of widely dissimilar forms, if they happen to be at all seemingly connected ; a practice, which at the least would be equally inconvenient with the more fashionable mania for subdivision and separation. As in other simple-fronded genera, the species are, however, really difficult of limitation. ‘The most successful attempts that have been made to cultivate this little plant have consisted in taking up the plant, in little clods of soil, and planting them in a compost of sandy loam, which resembles tho soil in which they naturally grow. Tn this way, the plants may be occasionally preserved and induced to reappear at the proper season ; but like all the allied species it ean hardly be considered as a manageable plant in the eultivator' hands,
