BRE er,

It was indeed 1689 that, with Keempfer's visit to this country, our alge were for the first time subjected to the study of scientific world of Europe. Since this time, not a little number of our algae have been brought away to Europe by several tourists and collecters, and such men as Harvey, Martens, Suringar, Kjellman, Hariot and de Toni may be mentioned among many others, who have studied our native alec and iden- tified them. In 1891, Hariot published his “Liste des Algues Marines rapportees de Yokoska,” in which he mentions that 233 species were already known up to the date of his publica- tion, and by his adding 21 new species, the total number becomes 254. In 1895, G. B. de Toni published his ‘‘ Phyceze japonicee Nove,” in which he enumerates 305 species, some of which were identified according to the specimens I sent him.

Since 1888, when I, as the first student on our marine algze amongst us, began my study, more than 350 species were studied, not a few of which are new species and, I doubt not, may be more or less interesting to the algologists in abroad. Now the main object of publishing this work is both to promote this branch of science in this country and to make our’ marine aleee more familiar to those who are interested in this study as well as to the algologists of the world at large.

Here, I want to add a few words that we are not placed in very favourable condition of studying alee by any means, especially from the lack of algological literature and reference specimens. or, as there is not yet any provision whatever

made in the Imperial University of Tokyo nor in any other

(catty)

institution of this country for the convenience of the students of alge, I had to gather the literature and specimens absolutely myself with very limited aliowance of means. Consequently the literature which are quoted under each species are restricted only to those which I had chance to concert with.

Before closing this preface, I would like to express my sincere thanks to those who have assisted me by specimens and works: to Prof. J. G. Agardh of Lund; to Mr. Reinboid of Itzehoe ; to Prof. N. Wille of Christiania; to Dr. Kjellman of Upsala; to Prof. G. B. de Tont of Padova; to Dr. M. Foslie of Wrondjchm’; tol #riot,) | miNemi<eMot wcll itomlatcm doi Fe Schmitz, and others. To late Prof. Dr. R. Yatabe, my first instructor on botany, I wish to render thanks for the general guidance he gave on my study. Lastly, 1 would like to acknowl- edge all kinds of help given by those who have sent me

materials from different localities of this country.

Yatabella hirsuta Gen. et Sp. Nov.

Yatabella Gen. Nov. GELIDIACEA.

Yatabella: Fvond filiform, growing in monopodial manner, irregualrly branched, consisting of two layers of cells; the inner, of larger, elongated cells, surrounded by very numerous and densely packed slender, longitudinally running filaments, covered by a few layers of smaller, roundish, cortical cells. Aanches closely imbricated with mulufd-echinate ramuli. Sporophyjlls produced from the prolongation of spines of ramuli. Tetvaspores roundish and cruciately divided, being lodged among cortical cells

of roundish, shortly stipitate sporophylls. Cystocarps binocular.

Yatabella hirsuta Sp. nov. NOM, JAP, Yetade-gusa.

Diagn.: Frond filiform, primarily erect, subsequently de- cumbent, irregularly branched. Lvanches closely set on all sides with multifid echinate, peltate ramuli, adhering to any object coming in contact with the frond. TZetrasfores collected in an irregularly roundish, shortly stipitate sporophylls.. Cystocarps

globualr, with or without apical prominence, shortly stipitate.

Hlab. On rocks and stones at the depth of 8-9 fathoms :

Hiuga and Kagoshima-prefecture.

Descr. Root a small disc with fibres. Fvonds single or tufted,

15-20 cm. high, branching from base without any definite order.

Pl. 1-V. Noy., 1900.

Branches arising on all sides, very patent, often 3-4 being arranged along one side, They are cylindrical, and attenuated above. They grow up here and there into flat, lanceolate or oblong, midribbed segments, becoming often very much slender and filiform above, adhering to other bodies ‘such as stones, gravels, shells, etc. By this way, the plant subsequently takes decumbent habit. All parts, save the denudated stem, bases of branches and the upper slenderer filiform portions, are closely loaded with multifid echinate warts which are peltate in insertion and are fixed to the branch by a slender neck. They are set as if imbricated, and the rachis may be seen through them, when not much crowded. A section of thicker portion of branches shows 4-5 of them sur- rounding angular axis or rachis. The echinate ramuli arise, at first, forming a minute prominence below the apices of branches which elongate in monopodial manner. Zetvaspores are produced in a small, roundish or elngato-oval, shortly stipitate sporophylls which are formed by the prolongation of spinose ramelli of echinate ramuli. Cystocarps are minute globular or oval, with or without apical prominence and furnished with slightly swollen pedicels. Colour is dull purplish-red. Szdstance is rigid and harsh to the

touch. In drying the plant does not adhere to paper.

The external appearence of the plant resembles Zamnoclonium hirsutum on account of having echinate ramuli; but the plant is widely different from the latter in many characters. Of the plants growing in this country, it presents some external resem- blance to Acanthopeltis japonica Okam., which also belongs to the family Gelidiacee. Acanthopeltts, however, is synpodial in its mode of growth, while the present plant has monopodial growth. And on this account, Yatadbella shows no affinity with Acanthopeltis,

not withstanding its external resemblances.

we

So far as I can judge from literature only, among the genera in Gelidiacee, Ptilophora seems to show some relations to the present plant from the presence of very numerous, stiff, spinose, processes growing from the surface of the frond. The abnormal growth of a lanceolate midribbed branches in the pre- sent plant seems as if to show its affinity with those plants which have flat and midribbed fronds.

I have collected the present plant at Oriuzako in the province of Hiuga on 13th July 1899, re. two days after my receiving the lamentable news about the untimely death of my much honored teacher, Prof. R. Yatabe who died on 7th July of the same month. For his honour I have selected the generic name “ Vatabella,” as the generic name “ Vatabea”’ was established formerly by Maximowicktz, though that genus was afterward reduced

as the synonymy of Razzanza Ito.

Fronds creeping on vatious kinds of calcareous alee, de- eumbent。 rooting from under surface. The “ Langtricbe” arise alternately from every fourth articulation; and the ‘ Kurztriebe,” which are flat and leaf-like, stand almost horizontally in double rows along the upper side of the decumbent stem, giving a dorso-ventral appearence for the plant. The latter arrangement of the ‘“ Kurztriebe,” however, is rather obscure; for, although piiemmleavesm(hes . urztgiebe )) areyme reality. inserted on) the dorsal side of the shoot, yet they spread out very widely on both sides, and appear to lie apparently on the same plane as the “Langtriebe.” The “ Avzzutrzebe” (i.e. leaves) varies from ovato- lanceolate to oblong, ending in a broadly acute apex with a tapering or constricted and oval base. The broader leaves slightly overlap one another with their edges. The length and the breadth of leaves measure 560-750 # and 131—281 / respectively. ‘Their surface is composed of horizontally arranged hexagonal cells of approximately equal length (34-38 /) and shows 7-11 cells in the widest row. The apices of ‘‘Langtriebe” are not inrolled,

but flat and straight; the ‘Kurztriebe” are patent or almost

horizontal, at first curving towards the growing apex of the shoot,

afterwards becoming flat and straight. In some specimen, a Kurztrieb ” has been found to show an abnormity as illustrated in Fig. 3a, and Fig. 5. Pericentral cells are 9-10 in the main branches, throughly ecorticated, with articulations half as long as broad. Zetraspores are formed in the more linear leaves, i.e. in the “ Kurztriebe,’ which contain 3 or 4 of them in a single longitudinal row in lower articulations, and are externally covered by two or sometimes three cells. vocarps are developed on either side but mostly on the outer side of the leaves slighty beneath the apex. Cystocarps are oval with a.rather wide ostiole, provided with a more or less elongated turbinate pedicel, which has mostly one or sometimes two wart-like or somewhat short spur-like prominences on both sides near the base of the cystocarp. When two of such prominences are present, one is smaller than the other ; but, one or both may be sometimes entirely absent. Of the two prominences, the one is transformed from the remnant of the apical portion of the original leaf, and the other is of secondary

formation.

Hab. On fronds of various kinds of calcareous algze and

others. Hiuga, Kishi, Sagami, Bosha, Noto. Fruit—summer.

This pretty plant has been first described by Mr. Holmes from materials collected at Enoshima by Mr. S. Okubo, After carefully studying the fructified specimens, I have been led to refer this species to Herfosephonia, and not to Polyzonza as Mr. Holmes has done.

At first glance, the plant appears to have a habit remarkably resembling that of W/olyzonza. But, the characters of the plant being as just described, it should, in spite of external resemblance arising from the obscurity of. dorso-ventral arrangement, be se-

parated from Polyzonia; for in Folyzonia there is no regularity

in the disposition of “Langtriebe,” from which both kinds of fruits are developed, while in the present plant they are formed

from ‘“ Kurztriebe.”

Fronds penicillate, with or without stem, not incrustated, formed of dichotomously branched filaments which are somewhat con- stricted here and there, and in the constricted portions cell-wall is so thickened that the protoplasm is connected only by a narrow canal. The constrictions are very far separated in the most part of the upper portion of the filament, but in the lower portion, they are shortly separated, so that the basal portion of filament appears as if somewhat moniliform. The stem (when present) is short, cylindrical and spongy, consisting of entangled basal portion of filaments and root fibres which are emitted from the side of filaments. The thickness of filament in our specimens measures 60-140 y, and the height of frond 2—7cm. Substance very flaccid and the plant having finer filaments closely adheres to paper in drying, but that having thicker ones, not. Colour of filament is light green, becoming dark green in drying and

that of stem is somewhat grayish green.

の zz Root fibrous, branched; some of the branches expand- ing into a small disk at the apex. frond terete, provided with thick and stout stem below, gradually narrowed above, much branched in an alternate or somewhat dichotomous manner, 5-20 cm, high, 2-3 mm. thick in the broadest portion. All the segments, except the basal denudated portion, are closely covered with disk-shaped, suborbicular ramuli which grow out one-sided. Ramu thick, about 3 mm. broad, somewhat spiral in the order of insertion, amplexicaul at the base; repand or irregularly crenulate at the margin, with simple or branched setaceous processes on both surfaces; some of the ramuli expand, in place of assuming the normal form, into short-pedicelled leaf-like phyllodia which are oblong or roundish, either smooth or muricated, 3-7 mm. long or more, 2-4 mm. broad. In some forms, almost all ramuli are trans-

formed into such phyllodia showing abnormity, as it is shown in

Cystocarps and tetraspores : August—October.

Acanthopeltis japonica, a species peculiar, as far as it is known, to this country, is distinguished from all the allied plants of the subfamily ZZZzz@ on account of its peculiar mode of growth by proliferating short-pedicelled, disk-shaped, peltate ramuli from the base of the uppermost ramuli. Another remarkable plant which I have established as a new genus, Vatabella, and have illustrated in Plate I, has so close resemblance with Acan- thopeltis in its external appearence in having multifid-echinate ramuli which are inserted in peltate manner, that I took it as a new species of Acanthopeltis, when I first colleted it at the province of Hiuga. Besides its external resemblance, both genera have their cystocarps as well as sporophylls bearing tetraspores equally produced from the spines of ramuli. But, Vatabella grows in a monopodial manner, as I have already stated under that genus.

The present plant grows abundantly in the warmer parts of our Pacific coast, extending from the southern part of Kiushiu to the Cape Inuboye, but is not yet known in Riukiu Islands as well as in,the coast of Japan sea. This alga is rarely free from the covering of sponges, bryozoa, sand and various kinds of cal- careous algae to such an extent that it is often taken as some-

thing else than alga.

Hypoglossum barbatum Sp. Nov. DELESSERIACEA.

Nom. Jap, Aige-deniha-nort.

Diagn: Frond perhaps decumbent, narrow, linear-lanceolate, tapering to both ends, branching by repeatedly proliferating similar segments from the midrib on both surfaces. /Pvroleferations alter- nate, but sometimes take apparently opposite arrangement. /Zzdrzb slender, jointed at short intervals, consisting of ecorticated three oblong cells, and destitute of veins. Marginal cells irregularly reticulated and give rise to root-like, jointed, simple or branched, fibres by fusion of two or more cells. zzz oblong, borne on

the midrib. Cystocarps unknown. Hab. Hiuga.

Descr. Only one small specimen has been found among marine detritus. The plant seems to grow at first decumbent and subsequently erect, judging from the presence of marginal root-like fibres. The frond is linear-lanceolate, destitute of veins, ‘tapering towards both ends. From the midrib of the primary frond repeatedly spring the leaflets of similar form, and their midrib emits others; the plant thus branches out by repeated proliferous growths from both surfaces, and the older portion seems to disappear, as the basal extremity of the frond is rounded and furnished with secondarily formed root-fibres (Fig. 6). The proliferations are single along the midrib, but here and there two

of them grow so as to appear to oppose one another at the

same point. This apparently opposite arragement of leaflets,

20

however, is due to the growth of lesser sort from the base of the antecedent proliferation, and is not strictly, so to speak, dichotomous or opposite ramification. The zzz み 22 is very slender, composed of three oblong cells in surface-view, jointed at short intervals, and ecorticated. Marginal portion of the frond consists of somewhat reticulated cells, the remaining being tesselated as it is the case in other species of the genus. Along the margin, rather thick, jointed, simple or slightly branched, rootlike fibres interruptedly arise in abundance, leaving the interval portion entire. They are formed either from the prolongation of a single marginal cell, or by fusion of three or more of them, and are often abundantly emitted from the apical portion of, or from slightly constricted part of the segments. Besides these root fibres, there is found a scutate disk as shown in the fig. 4. Sovz of tetra- spores are oblong, borne on the midrib of a leaflet, being produced by the confluence of linear ones formed along both sides of the midrib, and are lodged below the half way of the entire length of the sporophylls bearing sori. Cystocarps unknown at present.

Colour is clear rosy-red. Szbstance thin and delicate.

Affinity which the present plant has with /ypoglossum spathulatum (Kutz?) J. Ag. is beyond any doubt; but, in that plant, there is no marginal root-fibres. The apparently dichoto- 。 mous arrangement of proliferations in the plant in question makes us to remind that of Hypoglossum dendroides (Harv.) J. Ag., in which proliferations are always dichotomous, while in the present

plant such arrangements are only occasional and apparent.

Hemineura Schmitziana de Toni et Okam. DELESSERIACEZ. Nom. Jap. Mabutaye-norz. Flemineura Schmitstana de Toni et Okam., Neue Meeresalg. aus Jap., p. 76, Taf. XVI, fig. 6-12 (Ber. Deuts. Bot. Gesellsch., 1894, Bd.

EGS) ccm toum-tnye. yap. Nov., p20 +) ld: Syl Alo Vol: “lV. p: 72e 3) Okam- Ale. Jap, Exsic., Fasc. I, No. 18.

Frond solitary, adhering to substratum by roots which are either disk-shaped or branched monosiphonous filaments and produced from margin and under-surface, membranaceous, br tripinnate, faintly midribbed, whithout lateral veins, 10-15 cm. high, tapering below to a short compressed stipe in an adult frond. Segments lanceolate, broadly acute or roundish at apices, o.6-r.5 cm. in breadth, usually narrowed at the base, patent, with rounded axils. J/argin irregularly fimbriated with larger or smaller leaflets which either grow into sporophylls or remain as sterile. Very rarely leaflets proliferate from the midrib. Tetra- spores forming a dense sorus on each side of the midrib of sporophylls. Cystocarps subhemispherical and slightly oblique, sitting on the midrib of sporophylls, with a small terminal pore pointing upwards and towards the apex of sporophylls. Colour rosy-red. Swzdstance thin membranaceous, and the plant adheres

to paper in drying.

ffab. On rocks perhaps at low tide. Isé, Eno-Shima and Misaki (Sagami), Bosht, Kadzusa, Iwaki. Tetraspores and

Cystocarps—Summar.

“Diese schone Art, welche zu Ehren des Professor Dr. F. Schmitz benannt wird, ist am nachsten verwandt mit Memneura Jrondosa Wook. et Harv. (vergl. Harv. Nereis Australis, p. 116, tab. XLV, Delesserta frondosa Harv. Phyc. Austral., tab. 179), wie Professor Schmitz mir mitgetheilt hat. Die Cystocarpien der Harvey’schen Art sind, wie aus der Diagnose hervorgeht, am Scheitel hornformig verlangert. Bet Hemzneura Schmitziana sind die fruchtfihrenden Blattchen (Sporophylla) sehr gut differenzirt, wahrend dies bei Hemineura Jrondosa H. et 日 . nicht zu sehen ist; auch sind bet Hemineura frondosa die primaren Rippen dicker als bei Alemeneura Schuiwtziana; die wahrscheinlich zur Gattung Heminewra gehorende Delesserta cruenta Harv. FI. Nov. Zel. p. 240 habe ich nicht priifen k6nnen, und kann ich nicht entscheiden, ob und wie dieselbe von der hier beschriebenen neuen Art verschieden ist; die neuseelandische Art hat (wie aus der Diagnose in J..-Ag.. Sp. Il (1876), p. 485 hevorgeht) ganze Rander.”—De Toni et Okam. 1. c.

Root, a small conical disc. Fvond flabelliform; 4-10 cm. long and broad, rising from a small filiform stem which soon passes into a cuneate membrane ; this membrane expands and forks, and afterward is repeatedly divided more or less in regulary dt chotomous manner. Segments broadly linear, 0.5-t cm. broad, erecto-patent or spreading with blunt apices and axils. Sometimes one of the segments is accidentally torn off, and one or more proliferous elongations arise from the harmed ends, which become dichotomous like the rest. The marge which is usually quite flat and entire, sometimes throws out minute, lobed, and some- what fringed processes. Cystocarps linear, occupying the centre of the segments after the manner of a midrib, but never con- tinuous, being always interrupted about the axils. TZetraspores forming roundish or oval, wart-like, prominent nemathecia which

are scattered on both surfaces. Colour a bright pinkish-redl

PLATE XII. Isoptera Gen, nov. LOPHOTHALIE 生 (Rhodomelacez).

Isoptera: Frond filiform, compressed, 2-3 times alternato- pinnate, distichous, throughly corticated, with patent branches which are furnished with pectinated, monosiphonous, coloured “Tlaarblittern” altenatly arising in twos on both sides (only denuded in the lower portions). ‘ Lanxgtriebe” developed from upper one of the two consecutive ‘“ Haarblattern.’ Mode of growth of shoots is monopodial with a subobliquely articulated apical cell whose successive articulations soon give rise to paired “ Haarblattern.”’ Pericentral cells 4 in number, more or less thickly corticated. Zetraspores formed in upper swollen portion of slightly twisted, stichidia-like, short ‘‘ Langtriebe” which carry simple ‘Haarblattern,” usually in pairs in each articulation, making cross-way to each other. /Pvocarps produced on the upper side of the lowest or next cell of the rachis of mostly simple ‘‘ Haar- blattern ” which are developed near the growing apices of shoots. Cystocarps globular with more or less prominent carpostome, almost

sessile or provided with a very short apparent pedicel.

Descr.: The beautiful plant somewhat resembles in its external appearence to Lonnemarsonia Asparagoides. The frond is coespi- tose, attached to substratum by fibrous roots, filiform and com- pressed, 2-3 times pinnate, alternate and distichous, about 15 cm. high and o.5 mm. troad-in the lower portion... The entire plant is primarily divided into some main divisions which ramily in successive order, and the general outline of one main segment is broadly oval or lanceolate. The rachis of main branches are very slightly flexuous. The persistent, coloured, monosiphonous “ Flaarblattern” arise regularly alternating along both sides of branches, in such a manner that those issuing from every two consecutive nodes stand in. alternation on the sides. They are normally branched in a pectinate manner, that is 6-7 laciniae issue from every articulation along the upper side of the mono- siphonous rachis. a The latter, when young, is incurved towards the apex of the shoot which bears those “ Haarblattern,” but soon becomes straight and patent, and then either gradually becomes almost horizontal or curves backwards. Laciniae are directed outwards, standing almost parallel to one another. The rachis and laciniae are all sharply pointed at the ends. “ Langtrieb,” defiinte or indefinite, developes from the upper one of the two consecutive ‘‘ Haarblattern.” Consequently, “ Langtriebe”’ arise, as a tule, alternately from every 6th joint; but when they are more widely separated, they sometimes arise from roth, or when more approached, from 2nd, articulation. Simple, or not pectin- ated ‘“‘Haarblattern’” are of rather rare ‘occurrence except on the fertile branches; and, when they are present in the sterile portion, they are mostly placed beneath the pectinated one. Again, their disposition is commonly distichous, but not without some irregularities, especially in sporiferous: branches where- they

are arranged on all sides.

<

33

The shoot is composed of a distinctly articulated polysiphonous axis with four pericentral cells, coated internally with many layers of larger cells and externally with minute polygonal cellules. Mode of growth of shoot is monopodial with an obliquely articulated apical cell whose successive articulations soon give rise to pecti- nated “ Haarblattern.’””

Tetraspores are formed in the swollen potion of simple or

I

branched “ Langtriebe” of the ultimate order, which are more or less differenciated into stichidia and are provided with simple “ Haarblattern.” There are found two of them in each articula- tion (rarely one) arranged in such a way that every pair makes cross-way with that of the next. The surface of sporiferous por- tion is uneven, and owing to its slightly twisting, ‘ Haarblattern ” appear as if arising from all sides. The frocarpf is produced near the apical portion of growing shoot, being formed single on each ‘‘Haarblatt.” It is developed from the lowest basal cell or from that next to it along the upper side of the fertile “Haar-

y

bl&ttern ” which are generally simple; but a few laciniae are sometimes present. The cystocarps are globular, almost sessile or furnished with a very short apparent pedicel, provided with a slightly prominent carpostome and sometimes carry the remnant of the terminal portion of the rachis at their bases. Colour a bright red. Substance soft-cartilaginous and the frond imperfectly

adheres to paper in drying.

The present alga stands in the system near Lophothala and verona. From the generic character of Pteronza given by Prof. Falkenberg in Engl. u. Prantl’s Natiirlichen PHanzen-

familien, I. Theil, 2, p. 452, we learn that the frond is compressed

》

and branched out on both sides, whose “ Langspross” is furnished

2

with simple monosiphonous “ Haarblétern” which alternate in two

34

rows. Again concerting with Harvey's illustrations (Harvey's Ner. Austr. tab. XXVII.) and Prof. J. Agardh’s description (J. Ag. Sp. Alg. I. p. 1184) of Dasya pectinata (i.e. Pleronia pectinata), we understand that pinnae (i.e. “ Langspross”) arise from every second node and pinnulae (ie. ‘“ Haarblittern”) from every articulation,—both alternately and distichously. Thus the arrange-

,

ment of ‘“Kurztriebe” and ‘“ Haarblattern” is wholy different from that of those of the present plant which has all “ Langtriebe”’ always transformed from upper one of the paired “ Haarblittern” and strictly keeps this regularity for the general arrangement of ‘“Haarblétlern” and “ Langtriebe.’ Again, “Haarblattern” which are pectinated along the upper side of the rachis alternate alone both sides of branches in so regular manner that those arising from two consecutive nodes .stand in alternation on the sides. Plant having such a regular disposition of “ Haarblattern” and ‘‘Lanetriebe’’ does not find its position among established genera.

In the next place, Ptronia pectinata is said to have com- pressed or flattened frond according to Prof. Falkenberg’s description (though it appears cylindrical from Harvey’s illustration), which. has branches and “ Haarblattern” disposed in distichous and alternate manner. Moreover, some ("haufig 2 aufeinander folgende”) “ Haarbléttern”’ produce branches from their basal cells pointing upwards, This seems to me to show some relation with the pectinate branching of “ Haarblittern” in our plant; and, as also the compressed and disticho-alternate habit is same with /softera (though “ Haarblittern” are alternate in twos), the plant in consideration is not without some degree of affinity with Preronia.

The structure of stichidia in our plant is quite similar to that of Lophothalia which, however, differs from the present plant in having “ Langtriebe” and “ Haarbléttern” growing on all sides

35

2

of shoot. The plant in consideration has “ Haarblittern”’ some- times arising from all sides of shoot, especially on fertile portions, as I have stated above. From these relations, we may naturally infer the plant in question as one which stands near Lofphothala

and Freronia.

PLATE XIII. Neurymenia fraxinifolia (Mert.) J. Ag. AMANSIZ (Rhodomelacee).

Nom. Jap, /so-dasho.

Neurymenia fraxinifoha J. Ag. Sp. Alg. II, p. 1135; Schmitz u. Falkenberg in Engler u. Prantl’s Naturl. Pflanzenfam. p. 471.—Dictyomenia Sraxinfolia Harv. Phyc. Austr. tab. CXXIV.—Lpineuron fraxinifoliuin Kitz. Sp. Alg. p. 849.—Fucus fraxinifolius Mert. Turn. Hist. Fuc. tab. 193.

Root a broad disc. Fyvond leaf-like, linear-oblong, simple or pinnately lobed, with a prominent midrib and parallel veins, furnished below with a cylindrical stem which varies in length and thickness according to age of the plant. The ZZZz/ branches by producing similar segments repeatedly from both surfaces of the midrib. In specimens before us, the frond attains 10-20 cm, in height. As the frond grows in age, lamina of the primary leaf becomes decayed and the midrib is transformed into stipe. Thus the plant may have simple or branched stem. Lamina linear-oblong, 10-15 cm. long, 10-17 mm. broad, very obtuse at bases, emarginated and rounded at apices, slightly undulated, serrated throughout, midribbed and closely penninerved with slender, patent viens. Veins scarcely observable to naked eyes, obliquely ascending alternately from the midrib to marginal teeth, parallel in a short regular distance; upper veins curve at emargi- nated lobes and converge to each other. Marginal teeth are spinose and branched with subulate and recurved ramuli ; similar processes (simple or branched) also arise along veins and midribs, and consequently the surface of lamina is generaly rough. C7S-

carps unknown. Stchzdia are lanceolate or linear, acute, shortly

38

stipitate, containing a double row of tetraspores. Colour when recent is said to be a very deep full red, fading to reddish- brown in drying. Szdstance rigidly membranous, It does not

adhere to paper in drying.

Frond depresso-globular or sub-hemispherical, 2-7 cm. in ‘expansion, attached to substratum by its base, spongiose, composed of densely anastomosing cylindrical cells. As the frond grows in size, the older cells decay, making hollow at its base. Cells 2-10 times long as broad, branching repeatedly in every direction, with one or two ramuli at nodes, adhering to each other and other objects coming in contact with the frond by scutate tenaculae which arise from the apices or sides of ramuli. Colour grass-

frond single or caespitose, erect, rising from a common scutate disc, branching in a somewhat trichotomous manner, and by constrictions it is divided into joint-like, cylindrical or oblong internodes, attaining the length of 3o-4ocm. when fully grown. Branches patent, more or less trichotomous; every internode generally giving birth at its summit to three similar ones, some- times more numerous, sometimes fewer. Proliferous branches also arise (more or less densely) on all sides from several portions of internode, from the middle as well as from the filiform neck which connects.two internodes, All the internodes are separated by slender solid filiform nodes or isthmus, about 1-1.5 mm. long. The lowest joints are clavate or oblong, gradually or abwuptly tapering into short, solid, cartilaginous stem. The middle are the longest, cylmndrical or oblong, gradually becoming shorter and shorter above, and almost elliptical in terminal ones, with the diameter 3-10 mm. in the broadest part. Their length varies

according to the position; those of the median portion are often

Fronds caespitose, often forming a roundish tuft, filiform, 2-5 cm. high; attached to substratum by slender jointed hair-like roots whcih are emitted from nodes of the lower decumbent portion of frond. Filaments usually 177-192 / thick, of almost equal thickness throught and almost regularly dichotomous. Branches erect, furnished with proliferous branchlets springing from sides or forks; when they proliferate from forks, the ramification seems as if tripolychotomous. Ends of branches are somewhat club- shaped and sometimes straight but usually forked with inrolled and slightly swollen apices. The cortex surrounding the upper node of every articulation forms a circular ridge or rim, a little prominent obliquely outward and upward, so as to make a shallow cup or sheath which seems as if fo receive the base of the

articulation next. above. Along this rim, a whirl of mostly two-

48

jointed, colorless, pointed spines are more or less present. Hair- like roots are emitted from nodes of lower decumbent portion of frond in a transverse row beneath the line of spines. Lower articulations 3-6 times as long as, the upper ones gradually shorter than, the diameter, throughly corticated with a layer of cortical cells which consist of almost rectangular or hexagonal cells arranged in longitudinal rows. Cystocarps unknown to me. Tetra- sporangia are produced in upper branches (often in proliferous branchlets), mostly along the outer side, sometimes in a transverse row. They are produced from the larger cortical cells which form a ring around the periphery of the nodes, bulging out externally. An examination of the figures 5 and o will perhaps serve to make this relation more plain. Colour light red or pinkish. Swdstance membranaceous and the plant becomes fragile

when dried. It adheres imperfectly to paper in drying.

Diagn... frond compressed, two-edged, midribbed, decom- posito-pinnate ; branches distichous, alternate, patent, and also proliferous from the axils of pinnae; pinnee of simple character regularly alternate, deltoido-acuminate, entire; those of compound, suppressed in sterile frond, presenting only in fertile frond as a very short fertile pinne. Fruits of both kinds developed from pinnee of compound character, which are shortened and produced single or seriated along the margin of branches above the axils of simple pinnee. Cystocarps shortly pedicelled, involucrate. 72 み 2- sporangia collected in a dense globular aggregation on apices of the short pinnae, produced from the terminal cells of pinnule

and of opposite pinnelle, which are mixed with sterile—simple

or pinnated and subclavate— pinnule. Antheridia unknown to me.

Ffab. On rocks, stones, shells, calcareous alge etc. near low tide. Rather common along our warmer Pacific coast: Iwaki, Hitachi, Kadzusa, Boshu, Totomi. Cystocarps and tetrasporangia

—August.

Descripiton: Uhe voot- is a small disc. The frond is

caespitose, ancipito-compressed, 5-25cm. high, 2-3 mm. broad,

50

and has a more or less distinct, immersed, slightly flexuous midrib which becomes fainter gradually upwards. The ramification is irregularly decompound-pinnate, with patent branches the axils of which are rounded. The proliferous branchlets, which are always narrowed at the base, issue from or above the axils of pinne. The simple pinnee are broad at the base, pointed at the apex, with entire margin, and about 1mm. long. They are incurved when young, but erecto-patent or somewhat recurved when old. They have an excentric monosiphonous axis and are corticated to the apex. /yvuz/s of both kinds are developed from pinne of compound character, which are stunted and cylindrical. They are formed either singly or otherwise, seriated along both sides of branches above the axils of deltoid pinnae. The masses of の - sporangia are roundish or oblong, densely aggregated on the apex of short pedicels, that is pinnee of the compound character. They are developed from the terminal cells of monosiphonous pinnulze and pinnella. And these are accompanied by sterile pinnulz which are either simple and confervoid or pinnate and subclavate. Cystocarps are formed on a short cylindrical pedicel, involucrated with 7-8 thickly corticated ramult which are simple, cylindrical and entire, tapering towards the apex. Gonimoblast parted into two or three roundish gonimolobes surrounded by a colorless membrane. Antheridia unknown to me. The colour of frond is deep-red, turning to dark-red in drying. The substance is car- tilaginous and the plant adheres imperfectly to paper in drying,

except the younger portion.

The present plant may be considered as a 7 having opposite dissimilar pinnae, of which compound, that is pinnated, ones have been suppressed in sterile frond, the latter being re-

presented only in fertile form, and as the consequence, pinne

し 7

51

of simple character stand alternately. The compound nature of fertile pinnee is well shown in tetrasporic pinnae, as the tetra- sporangia are produced from the terminal cells of pinnule and opposite pinnelle. With respect to the affinity of the present plant we may consider that it exists with Pélofa Asplenioides, as it is shown by similar arrangement of fructified pinnae, by the alternate disposition of the simple ones, and by the obsoleteness of those of compound nature in both plants in consideration. Of the difference between Pélola dentata and Pt. Asplenioides it is so manifest that we need no further description. Among those /%/2Zze which have regularly alternate and similarly con- structed pinne, such as Ptlota formosissima, Ft. siliculosa and others (ie. species of Luptzlota Kuetz), we are far from finding any plant allied to the present Pxdota. In those just mentioned the arrangement of tetrasporangia and tetrasporic pinne are so widely different from that of those of Pk&lota dentata that no one can judge the present plant has any affinity with them. /#/ota Aspleniides has a wide range of distribution in the Arctic Ocean and in the Pacific, along the coasts of America, Kamschatka and Kurile Island, and it reaches down to Kushiro, a province in the south-eastern coast of the Hokkaido. Ptlota dentata is found in the warmer and southern coast of the Pacific, as far as it is known, extending from Iwaki to Totomi. In my opinion, it has certainly a close relation to L%lota Aspleniowdes having been naturalized and established as a southern representative. This plant is, as it is hitherto-known, only /%/ofa which is found in

the warmer part of our Pacific coast.

Root a small circular disc. Fyvonds single or tufted, simple, chord-like, sometimes twisted in age, 3-4mm. in length and 3-5 mm. or more in diameter in the middle, very much attenuated to a filiform stem at the base, and gradually tapering to a rather acute point at the apex, everywhere covered, when young, with scattered, pellucid or light-yellowish, gelatinous hairs; when old, these mostly disappear, the frond becoming more harsh and less lubricous and traversed by an internal tube which is divided at different intervals by diaphragms, not indicated by any external constriction or swelling. Frond consist of three layers: the in- nermost, of longitudinally running slender thread-like cells which form so-called sieve-tube in the vicinity of diaphragm; the in- termediate, of long, cylindrical or polyhedral cells becoming more slender outward, being covered by a few layers of epidermal cells i.e. the outermost layer. /araphyses clavate with slender neck, protruding above unilocular sporangia which are minute

Root fibrous, branching. Fronds single or caespitose, ancipito- compressed, linear, midribbed, branching or dividing from sides and proliferate from both margins and surfaces, 4-20 cm. high, 1.5-2mm. broad. Branches are sometimes more or less regularly alternate, sometimes much more irregularly ; and by the growth of proliferations into branches, ramification becomes more and more irregular. Proliferations, which are narrowed at bases, arise from the midrib, both margins, and intramarginal portions of both surfaces as well as from ends of branches. At the beginning, proliferate ramuli are very minute and ciliary; soon they grow up into narrow spatulate or oblong ramuli which usually become 2-3 times pinnately compound, rarely remaining simple or folia- ceous, especially in tetrasporic frond. Branches are rarely free from marginal proliferations, while their surfaces are often void of them. In a robust form, proliferations are so much dense that the rachis is invisible through them and the latter seems as if densely loaded with short and echinate ramuli. There is no

definite order for the disposition of branches which arise very

patent, often assuming almost horizontal position. Apices of all

sorts of branches terminate in truncate or blunt ends. Margin is flat and entire, excepting lower portion of the stem where -

both margins often become rough by wearing. The midrib is thick and conspicuous in full-grown parts, but is fainter in younger - or terminal portion of branches. [ Fruits of both kinds are produced from terminal pinnule | of proliferated pinne. Cystocarfs oval or roundish, slightly flattish, blunt or apiculated and consist of two chambers. TZetra- ‘sporangia densely collected in unaltered or slightly dilated pinnule. Antheridia unknown. Colour deep purplish-red. Swédstance rigid and. cartilaginous, becoming almost horny after drying. The plant does not adhere to paper in drying. | _ Fiab. On rocks, stones and shells, extending from high tide mark to the depths. of 1o-15 fathoms.

, Ns Suhria japonica has been first described by Harvey in 1859, ies x from the material collected at Shimoda (Prov. Idzu) by C. Wright. Since that time, no writer has made study of this plant till the appearance of. Schmitz’s work on Gelidiacce (Schm. 1.c.)。 who made a suggestion that Swhria japonica should be ranked among Porphylogossum. Av neice Il want to make a claim for referring this plant to the genus Gelrdium with the following reason. That Swhrta gaponica should not be allied with Swhrza vettata | ic) J. Ag., the typical species of the genus SZ/72Z。 1 am of the same opinion, with Schmitz who first made the remark on this point. Swhria vittata has, as it is well known, rather thin and

broadly linear-lanceolate, simple or irregularly branched, midribbed

59

frond which is furnished with obovato-linear,—‘ unverzweigte "3 or very slightly branched, but not pinnately compound,—fertile pinne, proliferating mostly from-margins as well as from the midrib. Swhria japonica has more narrowly linear and pcnnately divided frond having decompostto-pinnate, linear ramuli which are proliferated both from margins and surfaces. Plants having such different habit, | want to say, should not be kept in one and the same genus.

As to Schmitz’s view for classing Suhrea japonica in the genus Porphyroglossum 1 am quite far from agreeing with him. Forphyroglossum Zollingert Kuetz.” has an ecostated, simple or sparingly branched and undulated frond, from whose surfaces, either median or otherwise, 一 and not from margin (?)—very numer- ous, foliaceous, simple, minute and linear pinnule are proliferated. The mode of ramification. of Swhréa japonica, as it is shown in proliferating pinne, can be said to be nothing but pinnate, though in some forms very few ordinary branches are present. The plant in question has midribbed frond and is furnished with pinnate proliferations, arising from both surfaces and margins.

Now, since my discovery of Geldium subcostatum Okam.® which has midribbed frond, Schmitz has studied the. plants which were considered to be related to Gelediacee up to that time and has brought some important changes to the classification of Gelidiacee in general; and consequently, the diagnosis of Gelidium has suffered variations in.certain points. And thus, the presence of midrib in an allied. alga gives no objection for placing it in that

genus. Gelzdium pristoides (Vurn.) Kuetz., again, with which the

2) As to Porphyroglossum Zollingeri Kuetz., I am sorry to say, 1 have no specimen to examine and I have to study it only from the illustrations given in Kuetzing’s Tab. Phyc. Vol. XIX, t. 45 and descriptions given in literature. ; 2 -.~ 3) Schmitz. l.e.,-p. 1-2, Taf.. X.

alga in consideration shows many points of resemblances, has simple or decomposite proliferations either from the midrib or surfaces as well as from margins, making the proliferations to be no hinderance for ranking related alga among eZZzzzz. Still again, the mode of ramification in Swhria japonica is pinnate, as I have already remarked, and both kinds of fruits are formed, as in niany species of Gelzdium, beneath the apices of terminal pinnule of proliferated pinne, which is also the case in Gelzd@ium pristoides. From the points so far stated, I think it more proper to place Swhrza zaponica in Gehdtum than putting it in Swhrza or in Porphyroglossum.

Among hitherto-known species of Gelza:um, the present alga has so much remarkable resemblance with Gelidium pristoides, the specimens of which I have in my herbarium, that the illustra- tions given in Kiitzing’s Tab. Phyc. Vol. XVIII, t. 65 remind us, at first glance, a certain form of Suhria japonica. - The chief differences are that our alga has broader size of frond and non- denticulate sporophylls.

In Martens’ Preus、 Exped. n. Ost-Asien, Tange, p. 133, Gehdium pristordes Turn. is enumerated among our marine flora as collected by Siebold and De Toni mentions the same species in his Phyc. Jap. Nov. p. 22. Geldium pristoides, however, does not grow in this country, as far as my knowledge goes, and I want to take off that species from the list of our marine alge, notwithstanding of my ignorance of Siebold’s specimens, as I

believe it to be nothing but Swhrza japonica.

Fronds ceespitose, rising from a circular disc, stipitate, with a short compressed stem which soon passes into cuneate base of flat, linear,. dichotomo-flabellate frond, 5-17 cm. high. Segments irregularly dichotomous, with upper ones sometimes somewhat alternate, erecto-patent linear or linear-cuneate, 2-5 cm. broad, slightly widening towards forked portions, rounded at axils. Margin furnished with interrupted laciniee which are simple or com- pound ; simple ones subulate and teeth-like ; compound ones lobed and lacinulated. In some specimens, almost all margin is lacinulat- ed leaving no gulf entire, as it is illustrated in fg. 2. Cystocarps are immersed in the substance of laciniee, prominent above either surface of frond and crowned with three to five or more blunt horns in which orifices are formed from within outward. They are produced single or three to four or more aggregated. Zetra- sporangia are scattered over the whole surface of frond, oblong, cruciate, disposed among cortical cells. Colour beautiful rosy-red. Substance thin and membranaceous and often becomes rather

cartilaginous when old. Plant does not adhere to paper in drying.

Hab. On rocks and other substances between tide marks.

This species is most nearly resembling to Callophyllis rhynche-

carpa Rupr. and, beyond any question, it has close affinity with

the latter. But, Callophylis rhynchocarpfa has entire margin for

a longer distance than it is in the present plant, and toothed or_

lacinulated portions seem to be mostly limited to upper portions, as I judge from a specimen of it collected at the eastern coast of Sakhalin.

Plants caespitose, rising from a common scutate disc, with a short subcylindrical stem, soon expanding into the cuneate base of frond, ro-2o cm. high. /vond flat, coriaceous, dichotomously or subpalmately lobed with broad linear, patent segments whose axils are rounded. Segments, which are 1-3cm broad, sometimes end in blunt or ligulate, or sometimes in acute or bifid apices ; in other cases, terminal segments are much slenderer than the remaining portion, being divided in repeatedly dichotomous manner. Margin is usually flat and entire, sometimes slightly undulated, and is often provided with proliferous segments which are similar in character to other portion. Frond internally consists of large and thick-walled cells, elongated between margins and externally covered by a few layers of cortical cells.

Tetrasporangia are densely scattered over both surfaces of frond. Cystocarps are hemispherical or almost globular, densely scattered over both surfaces of frond. Pericarp is thick being

constructed of many layers of cells and is provided with a

PLATE XXIV.

Champia bifida Okam. nov. Sp. RHODYMENIACEA. Nom. Jap.: /zra-watsunagi-so.

Lagn.: Fronds perhaps decumbent, loosely intricated by coalescing to each other, compressed, throughly articulated, usually 2-3 times distichously pinnate, with branches alternate and some- times verticillate, patent, often subdichotomous above. Branches narrowed toward bases, acute or bifid at apices, with joints scarcely or slightly constricted and one-third or one-fourth long as broad. TZelrasporangia forming a dense orderless aggregation between joints. Cystocarps scattered, sessile and ovoid with a

promint carpostome. ffab, Enoshima and Misaki (Sagami). Fruits—late in Spring.

Decrip.: Plants are loosely intricated with branches coalesc- ing to each other by the formation of short root-like processes, and may perhaps become decumbent by adhering to substratum in the similar way, as this alga is only found washed ashore, and whenever we cellect it, we can not obtain a perfect plant with root, though the lower portion of frond is found to taper into subcylindrical stem. 7/ ヶ ogz〆 is compressed, usually branched distichously in 2-3 times pinnate manner, attaining the hight of 8-1ocm. in full grown plant. Branches are opposite or alternate, often here and there dichotomous and sometimes furnished with verticillate segments which arise from sides and

surfaces. The breadth of branches measures 2-7 mm., usually

68

5-6 mm. in broader portions. They are gradually narrowed towards their bases, patent and terminate in acute or bifid apices. Joints are not constricted in greater part of frond, especially in younger portions, but slightly constricted in lower and broader parts. The length between joints is one-third or one-fourth as broad.

frond is tubular, separated into small compartments by thin, cellular, one-cell-layer thick diaphragms at joints. The wall ef the tube is thin, internally consisting of a layer of larger roundish cells whose interstices are occupied externally by smaller cortical cells. Through the tube, there run longitudinally many, slencer, colorless, simple or branched, articulated filaments which arise from the cells lining the wall of the tube and pass through diaphragms. These filaments or hyphee are laterally provided with a smali globular cells what are known as “bulb-cells.” The filaments converge at extremities towards the apical points of frond.

Letrasporangia are densely collected over the surface between joints of the middle or lower portion of a branch, without any difinite order, bulging in towards the interior of frond. Cyséo- carps are scattered around branches, sessile and urceolato-ovoid, and are furnished with prominent carpostome. ‘The inner layer of pericarp is consisted of a beautiful network of slender fila- ments which arise from the tissue forming the bottom of the spore-cavity. Gonimolobes form a globular mass with densely packed spore-flaments paniculately branching from a large pedicel- cell, making spores to ripe in the terminal articulations and are covered by hyaline gelatinous envelope.

Colour orange-red fading to yellowish-orange in prolonged immersion in fresh water. Széstance gelatinoso-membranaceous

and the plant firmly adheres to paper in drying.

Champia lifida differs from Chamfpia compressa Harv., Ch. Nove-Zelandie (Hook. et Harv.) J. Ag. and the allied plants chiefly by having bifid apices, subdichotomous branches and

broader size of segments.

Root a circular disc. Fronds form densely glomerous tufts, 3-7 cm. high in our specimens. At the beginning, frond is lan- ceolate and thin membranaceous, with the growing apex rolled toward the ventral surface, pinnulated along margin, and pro- liferates segments similar to the primary frond from the midrib of the same surface. Proliferated segments are fasciculated after the manner of a rosette, and these segments, after having at- tained their full length, give rise to other proliferations in their turn. By this way, the simple primary frond becomes decom- pound. The midrib is insignificant in a lamina which has no proliferation, but becomes very thick and prominent, when pro- liferations are produced from certain points of the midrib, by gradual cortication over both of its surfaces, along the line ex- tending from the the points to the base of the lamina. In this

manner, the lower portion of the primary frond becomes thicker

72

and thicker, and by the abrasion of the wing, the midrib changes to the stem which ramifies with no definite order. All the seg- ments are same in shape and other characters. They are lan- ceolate, rolled up at the apices towards the ventral surface and are furnished with minute pinne or ‘ Flankendste” of German writers, which appears like marginal teeth, Pinnee, which are of endogenetical origin, incurve towards the ventral side and carry similar pinnule along their margins. They remain mostly short, but sometimes grow up. into segments similar to the rest. Thus, the ramification is brought about by two ways, firstly Ly the growth of pinnee and secondly by resette-like proliferations. Among our specimens, I have seen some forms in which root-like processes are emitted from marginal portion of an older lamina (fig. 5). And in other case, I have detected a plantlet which has developed itself into a separate individual by emittng root-fibres from the lower harmed end of the midrib of lamina (fig. 4). From these instances, the alga seems to adhere to substratum by its parts and not uncommonly to effect vegetative multiplication.

Lamina is entirely destitute of cortication excepting the thickened midrib, and consists of two layers of horizontal rows of elongated, hexagonal cells which are derived from paired pericentral cells disposed on both sides of the midrib. The height of the cells of lamina measures 72-120 and we may count about 150 cells between margins. Along dorsal median line of limina, a row of deciduous hair-leaves is arranged, which are branch- ed many times dichotomosly. The original lamina can always be seen even in thickly corticated portion such as stem and branches.

Tetrasporangia are formed in slightly altered pinnule in

double rows along the ventral surface, being covered by two

so-called ‘cover-cells.” Hinnulee which produce tetrasporangia are

lanceolate and simple or sparingly branched and are usually

1

marked by rudimentary growth of hair-leaves. Anthcridia and cystocarps are unknown to me at present. Colour Leautiful rosy-red. Szbstance of lamina thin and membranaceous, that of stem and mdbrib cartilaginous. The plant does not adhere to

paper in drying.

Plant is dendritic, forming a large, dense and roundish tuft, and rises from matted surculus. Frond is stipitate, erect, cylin- drical and tubular, 2-3 times pinnately branched and is 6-18 cm. high, attaining 1-1.5 mm. in diameter. Stem is percurrent, slightly narrowed at base, and is constricted into joints at various distances. Branches of every order are opposite or verticillate, but not with- out some irregularly inserted ones. The lower branches are usually longer than the upper, and their lengths become shorter and shorter upwards, and, as the consequence, the plant assumes pyramidal outline. All the branches and branchlets are very patent or almost horizontal, especially in lower branches, stand- ing on rounded axils, and arise from neighborhood of node or from internodes where segments widen out in some measures. Their bases are somewhat narrowed and their apices are blunt. Lengths of articulations are lonzer in the lower portion of stem and larger branches, becoming gradually shorter upwards. Upper portions of branches are catenato-constricted with fusiform

or ellipsoidal segments, especially so im tetrasporic fronds.

ones, but in other cases, their branches are much more elongated, often appearing to unaccustomed eyes to be entirely different from the typical plant. “2 The innermost layer of the wall -of frond is composed of 3 it loosely set and longitudinally running filaments to which so-called gland-cells are wanting. Outside of this layer is occupied by a

| thick layer, composed of internally larger and externally smaller | cells, which is covered by a layer of anticlinal, cortical ceils. At

constricted places, there are transverse septa which are composed of an aggregation of irregularly arranged roundish and elongated cells. These septa divide the tube into various compartments

and are connected with the inner wall of the intermediate layer

by filamentous cells. There are no longitudinally running fila-

developed from cortical cells and bulge in towards the cavity of

cortical cells which become filamentous there. They are roundish

or elongated and are triangularly divided.

PLATE XXVII.

Phacelocarpus japonicus sp. nov. SPHA ROCOCCACEA.

Nom. Jap, Az2-n0-wo.

Lagn: Fronds coespitose, rising from a circular disc, copiously branched almost from the base in distichous manner, membranaceous, ancipito-compressed above, subcylindrical in older parts, faintly midribbed, narrowly winged and pectinato-pinnatifid with broadly subulate or deltoid, patent lacinie, whose lengths are shorter below, subequal to or a little longer above than the breadth of rachis. Fruits of both kinds axillary and stipitate. Tetrasporic receptacles elongato-ovoid, shortly pedicellate. Cysto- carps flattish-globular or reniform with a furrow-like opening on

the summit.

Ffab. In deep waters. Ise, Shima, Sagami, Kazusa, Hitachi,

Iwaki. Fruits—Summar.

Fronds arise solitary or a few together from a broad scutate and circular disc which is 5-8 mm. broad, and branch copiously almost from the base. The mode of ramification is distichous and the plant attains 15-20cm or more in height. Branches are irregularly decompound in alternate manner, intermixed with longer and shorter ones, erecto-patent, and furnished with acute axils. The lower portion of frond as well as of larger branches is, in older specimens, subcylindrical by the decaying off of

lateral teeth; but other part of frond is pectinato-pinnatifid with

80

broadly subulate or rather deltoid, flat lacinia. They are mostly spreading and alternate, and are, as a rule, a little longer than the broadly linear portion i.e. rachis of frond. Those on the upper branches are incurved and longer than the breadth of rachis, while on the basal portion of all branches they are shorter, deltoid and patent, giving subserrate appearence to the rachis. The longer laciniz are about 4 longer than the breadth of rachis. Branches are furnished with the slightly prominent midrib, and the wings are broader on the upper than on the lower portion of branches.

The central portion of frond is occupied by an axis, composed of thick, cylindrical cells.. From a portion a little higher than the middle point of each axial cell, four branches arise in. verticillate manner. Of 人 es two shorter ones are. directed towards sur- faces and they are soon lost becoming indistinguishable from rhizoidal filaments which densely surround the central axis. One of the other two reaches the apex of lacinia, while the remaining one reaches the axil of lacinie. The latter may give rise to normal branch, and in fructified frond, fertile ramulus developes from it. Around the axis there is a more or less thick layer of longitudinally running rhizoids which branch dichotomously and anastomose to each other. The rhizoidal layer is again covered by a thick intermediate layer of which the. inner cells are larger and roundish. They become gradually smaller out- wards and are finally covered by a few layers of cortical cells. Some of larger cells near the surface are filled with orange- coloured contents.

Mode of growth of the frond is terminal, with a large apical.cell which is horizontally or slightly obliquely jointed. The

successive cells just beneath the apical cell soon give rise to

alternate and incurved lacinize which elongate by division of

81

their own terminal cells; From axils of lacinie, the apices of young ramuli, either sterile or fertile, make their appearence. »

Cystocarps and tetrasporic receptacles are axillary and pedi- cellate. Their total lengths (including pedicels) are usually same as those of lacinia. Receptacles of tetrasporangia are oval, containing numerous cavities excavated under the surface-coating. The wall of this cavity is composed of loose, moniliform filaments, among which elongated, clavate or oblong tetrasporangia, divided in zonate manner, are situated.

Procarps are unknown to me. ~Cystocarps are formed solitary or often two together, inserted obliquely beneath the apices of fertile ramuli, and are sometimes accompanied by abor- tive laciniee. The form of cystocarps is irregularly roundish and more or less reniform being slightly appressed in the same plane with the surface of frond. Each is furnished with a more or less gaping slit-like opening which runs on the summit in the direction of the longer axis. Placenta is laterally appressed on the plane parallel to the flattish side of cystocarp and neucleus is laterally flattened by the closely lying flaps of thick pericarp. Placenta is composed of numerous and several times forked spore-filaments which are densely packed together. The terminal cells of these tufted spore-filaments which form the vaulted surface of placenta are transformed into globular or elongated spores. Neucleus is mostly single, but another smaller isolated one is formed in the same cystocarp. In some specimens, fertile ramuli become abortive and develope into irregularly branched ramuli. They are mostly destitute of laciniee, but sometimes a few of them are formed on those ramuli and even cystocarps are thus developed.

Colour, when alive, is deep red, changing, after long immer- sion in water or exposure to air, to beautiful red and then orange.

Substance is thin and membranaceous except thickened midrib

82

and stem which have cartilaginous consistence. In drying, the

frond does not adhere to paper.

Phacelocarpus japonicus may be placed in the subgenus Liuctenodus (Kg). F Ag. in the neighborhood of 2. Labillar- dwert. On comparing the former plant with the latter, it differs in several points, viz: by smaller statue of frond, by thinner and softer substance, by less thickened midrib, by broaderness of wing of branches, by shortness and more distant arrangement of laciniee. The length of longer laciniz is, as stated before, about + longer than the breadth of rachis ; and even in well-developed ones, their bases are somewhat broader than the base of lacinise of Lhacelocarpus Labillardert. Lastly, the lacinie are more widely separated and are much more spread than in the latter - species.

In the point of its having broader wings of frond, the present plant resembles Phacelocarpus alatus Hlarv; but the latter plant differs in having pedicels of the both kinds of fruits transformed fromlacinie. Both Phacelocarpus apodus F Ag. and Ph. sessilis flarv. differs from the plant in question in having more slender and subulate laciniz and the former species, moreover, in having verrucose cystocarps. Lhacelocarpus epipoleus Holm. resembles to the present plant in the form, length and arrangement of lacinize, but it differs in having thickened rachis and externally

invisible midrib as well as in the mode of ramification.

PLATE XXVIII.

Cutleria cylindrica sp. nov. CUTLERIACEA.

Nom, Jap. AZuchi-mo.

Diagn: Fronds of the sexual generation high, cylindrical, stupose at base, dichotomous, with patent axils, tapering to both extremities and filiform above ; of radial structure, being composed axially of elongated and loosely set, filamentous cells, by the decay of which the frond becoming tubular afterwards. Sori of both sexes forming irregularly roundish, warty prominences, densely scattered around branches; female gametangia oblong and the male cylindrical. Plant of the asexual generation is not

known at present.

flab, On rocks between tide-marks. Ise, Shima, Sagami,

Bosht.—Gametangia in May.

Fronds arise solitary or in tuft from a common callous disc of diameter of a few milimeters. They are cylindrical and furnished below with a short stem. Lower portion of stem and surface of disc are stupose from the presence of buffy-coloured hairs. The hairs are monosiphonous and branched divaricately, being elongated by the division of terminal cells which are rich in yellowish-brown contents. Above the stem, frond is repeatedly forked, forks being nearer to each other in the lower part of frond, while in the middle and upper portion, they are more and

more distant. Frond is, for the most part, 2-3 mm. thick in

ta 1

86

diameter, gradually tapering to both extremities, and elongates above into slender segments. Segments are widely parted, making a gentle curve from origin, and are often loaded with irregularly inserted and similarly formed branches. The height of plant, when fully grown, attains 30-50 cm. in length. .

Of the structure of frond, there are three layers. The axial layer consists of longitudinally running and loosely set, filamentous cells which are connected with those, forming the inner wall of the intermediate stratum. This axial tissue’ becomes destroyed

as the plant advances in age, making the frond. tubular. Outside

of this, theré is a thick intermediate layer which is composed of large, roundish-angular and almost hyaline cells. These become

gradually smaller as it proceeds towards periphery, and finally

pass into infra-cortical tissue. The latter is formed of smaller coloured cells and is covered by a layer of: anticlinal epidermal cells which are often transversely divided into two. All the cells are united to each other by the formation of pit which appears to be similar as it is well known in cells of florideee.

Mode of growth of frond is trichothallic, that is, the growing

apices of branches dissolve into a tuft of penicillate hairs which

are free from each other down to the base and greenish-olive in

colour, These hairs consist of jointed: cells which are here and there divided by longitudinal walls, and the articulations appear in surface-view to be composed of a few cells zonally. arranged. By repeated division of the basal cells of hairs, new parts are added to frond, as it is well known to plants. of this. genus. After- wards, they are dropped off, leaving the apices of fully: grown branches slender and naked. |

Sori of both sexes form, on different individuals, irregularly

roundish, slightly elevated, warty prominences which are densely

scattered around branches, except in the upper segments and

87 and lower part of frond. The female sori are slightly greenish- olive, while the male are whitish in colour. On making section through a sorus, we find many jointed hairs formed from the elongation of epidermal cells, which are found to be either simple or branched and of unequal lengths. They elongate by intercalary cell-divisions. The part of the fertile hair, which forms a gametangium, is at first transversely divided and then longitudinally, and by this way, cylindrical or oblong gametangium is formed, The latter is either formed on the apical portion or sides of fertile hairs. ‘The female sporangium is longer and thicker and is of larger compartments than the male, and its content is densely greenish-olive, while that of the male is almost colourless. The pore formed on the side of each loculus, as it is clear from the empty gametangium, furnishes the exit for female gametes which I have hot yet been able to observe. As to the asexual form of this plant—that is the Av/aozontal plant—is not known at present.

The colour is yellowish-olive when fresh, turning almost blackish when dried. The substance, when fresh, is rigid, cartila- ginous and brittle; it much shrivels, and plant does not adhere

to paper in drying.

A distinct species from the form and structure of frond, The present alea is the only species known of this genus in this country. From its general appearence, it makes us remind Stlophora Lyngbya F Ag. and it is somewhat interesting in morphological point of view.

In structure, the present alga differs somewhat from that of hither-known species of this genus, as it is constructed in vadzal symmetry instead of を Zg/, and it has, in its axial layer,

loosely set filamentous cells,

88

In form of frond, Cztleria adspersa (Roth) De Not., on the one hand; has flabellate, multilobed and Zonaria-like frond which shows tendency, in adult state, “tov pass ‘into’ a form somewhat resembling to Cut. multifida (Sm.) Grev. as it-is shown in Zanar- dini’s Icon. Phyc. Meditr-Adr., Tav. LVI. Cytleria pacifica Grun., on the other hand, has thin-membranaceous, linear, dichotomous and elongated frond, while CzZ compressa Ke. has compressed, coriaceous and dichotomous one. Now, CZ/Z2Z cylindrica, as its name indicates, has cylindrical frond, and may perhaps be allied- with Cyt. pacifica or compressa. By the discovery of the present plant, the genus Cyd/eria comprises, in regard to the form of frond, three variations, namely, fan-shaped, compressed and cylindrical, and also, in respect to the structure, three diver-

Sities, i.e, dorso-ventral, bilateral and radial.

Fronds are densely tufted, erect and filiform, 25-40 cm. high, about 0.5-0.7 mm. thick. The basal articulation is more or less elongated into cylindrical stem (often 4cm. long, 0.7-0.8 mm. thick), which is annulately constricted at the base for a short distance. From lower extremities of joints extracuticular, decur- rent root-fibres are emitted, which remain very short in upper joints but becoming somewhat longer in lower portion of frond. And those fibres emitted from lower portion of stem, branch in an irregular manner and are septate at various distances. Branches are produced from nodes in an alternate manner and often 3-5 (mostly three upwards) arise from the same node. They are fastigiate and terminate in blunt apices. Lengths of articulations are longer in lower branches and shorter in upper ramuli. They vary in length from three to eleven times or more as broad. Substance is stiff when fresh, cells being provided with thick, lamellated walls, and the plant does not

adhere to paper in drying. Colour is deep bluish-green, fading

to reddish brown when dried and then presents glossy appearence.

Plants form a rosette-like tuft composing of fan-shaped, radially folded or undulated, leatlike nets, 3-4 cm. in extent. Net is constructed of repeatedly palmate and radially arranged, cylindrical cells which form the main veins of leaf. From almost every node of these veins, arise smaller cells which loosely anastomose to each other by means of the formation of terminal tenacula, forming angular meshes between. The size of meshes of the upper portion of frond is smaller than the lower, and it gradually diminishes as it proceeds upwards. Intercalary division of cells is often perceptible in those of main veins. Lower cells of the main veins are much elongated, their lengths being 5-6 times or more, while the upper ones are 2-3 times long as broad. Lengths of cells of the veinlets (if we may call those cells which arise from the main veins) are mostly subequal to or twice as broad. Tenacula have no such crenulated structure as

it is usual to Duectyospheria, Loodlea, Valona etc., but, here,

another part of frond, only slightly thickens, expanding and forming a circular or slightly crenate, cohesive disc, and no septation occurs at a short distance from the apex, as it is also the case with other typical tenaculum. Mode of growth of frond is acropetal and the margin is formed by free ends of ramuli. The number of rays of the main: veins is 3-5 or more. Cells in the basal portion of frond emit root-fibres which running

together downwards form a stem-like process.

The genus Ahzpediphylion has been established by Heydrich, based on Anadyomene. reticulatum Asken., who had done a careful study of the present plant and Axadyomene, especially Anadyomene Wright Harv. and throughly discussed about the difference between these two genera. Here, I refer our plant to the present genus according to Heydrich's view. On making this referrence, I only resorted to his work cited above, and therefore, I think it better to express, in this place, the reason why I have referred our plant to this genus, Our plant may be identical with his. It has main veins and veinlets as illustrated by that author in his Taf. XV. fig. 1. Again, tenaculum: which has been described above may be identical with his so-called tenaculum, as it appears from his illustration and description given in lec, p. 282, ‘Nach denselben Autoren........; solche vor, die nur ausgebuchtet sind, ............. Solche Tcnaculee besitzt

Rhipidiphyllon.” Murray and Boodle state that the similar ad-

93, hering organ occurs in Muecrodictyon Velleyanum Decne. = M. umbilicatum Zanard,; and also, I myself ascertained its existence in MWicrodictyon umbilicatum Zanard. collected at Gulf of Naples and sent from late Prof. Fr. Schmitz. Now, by putting aside the common character, 1. e. possession of tenaculum, from PR/zpzar- plyllon and Microdictyon, the former differs simply in its having two kinds of cells, viz. those forming the main veins*and veinlets, as well as non-umbilicated habit. I am really in accordance with Heydrich’s view in so far as the difference of Aupediphyllon from Anadyonmene is concerned, but, it seems to me rather weak to separate the former genus from Jcrodictyon, simply by the differences just spoken of. If existence of the present genus be allowed, it should stand between Microdictyon and Anadyomene, and may be said to be more allied to the former than to the latter. At any rate, here I have described the plant in question

provisionally under the genus Rizpedzphyllon.
