Vol. XVI, t. 50, f. d-e. Fronds numerous from the same base forming a subglobose tuft, attaching to stones, rocks, shells etc. by basal fibrous roots trans- formed from branchlets (sometimes the plant attaches to another alga by upper branches as shown in fig-. 4), compressed, linear or filiform, thin, membranaceous, generally nearly 7 cm. hicrh, but sometimes not above 5 cm. and at others 15 cm. long, their width about 0.5-2 mm., often very fine upwards, everywhere gently flexu- ose, much branched from the very base, or in some robust ones lower portions denudated and furnished with remains of wasted branches. Size of fronds, breadth of parts, density of branches and the substance much vary according to specimens. Branches all distichous, 3-4 times decompound pinnate, alternate and patent, the lower ones longer than the upper and gradually becoming shorter above, so that the ramification is somewhat corymbose ; they are throughout alternate in geminate manner, of which the lower one is always simple and the upper decompounded, and the simple one is 2-3 mm. long, entire, tapering to a fine point from broader base, and more or less incurved. In extreme branches ramuli are also arranged in alternate rows, two on one side (some- times here and there three) and as many on the other, in all of which lower or the lowest one is always simple and the upper with PL. CI— CV, May. 1913. still smaller ramelli on their upper sides.— —Tetrasporangia are formed in sporophylls which are seriated along the axils ; sporo- phylls are in some almost simple or sparingly branched, in others much branched in stellate manner or dichotomo-dccompound, with sublanceolate or linear ramuli and sustained with a short pedicel and contain double rows of zonate tetraspores. Cystocarps glo bular and sessile formed on the sides of branches. Colour a beautiful red. Substance thin membranaceous, somewhat soft car- tilaginous in robust ones and the plant adheres to paper in drying except robust ones. Remarks: In making the identification of the p.^sent plant I have not been able to see any reliable specimens except the lit- erature quoted above. Plant enumerated in Martens' Preus. Exped* n. Ost-Asien, Bot., p. 119 under the name Plocamium affine Kg« which was collected on Capca Richardiana at Yokohama is most probably same as the present plant. So also Plocamium botryoides determined by Heydrich (Einige Algen von den Loo-choo- oder Riu Kiu-Inseln p. 103; Kuroiwas No. 57) from Ryukyu specimen sent by Kuroiwa, who put many specimens under my disposal in common with Heydrich, as I judge from the identity of the num- ber denoting his specimens.

Ramifications are between alternate and subdichotomous with main branches set widely dichotomous, furnished with short patent alternate branches and beautifully pectinato-pinnat- ed along upper branches, leaving the lower portion naked, except for a few decayed pinnae. Pinnae 3-5, usually 4, the lowest one simple or compound, sometimes slightly bent backward, the higher in series pinnulated in the usual manner. Secondary pinnae and pinnulae arise along the side opposite to that, where the normal ones stand. They are subulate or spinose, and shorter than the normal ones, and are either simple or similarly pinnulated. They do not correspond in number to the normal ones, and are not definite in arrangement, but are mostly alternate with the normal ones. — Stic/iidia transformed from pinnules of both normal and opposite pinnae and are thus seriated along both margins of rachis. They are swollen and usually 2-lobed on a common slender pedicel and are recurved appearing like the let- ter r or the horn of a sheep ; they are sometimes single, the one branch being suppressed, or one remains simple, while the other is PL. cm. 5-77 6 3 Z 4- Plocamium oviforme Okam. & #> 1$ #> 0 Fig1. 1-5.

C, Fig. 7-11 I published an Acetabularian plant, as a new sp. struck by its smallest size, under the name of Acetabularia minutissima Okam.; but more afterward I came to doubt its specific value and by closer examination I found it to be identical with Acetabularia polypkysoides Crouan ; and so it must be reduced to a synonym of ACETABULARIA POLYPHYSOIDES Crouan. Acetabularia polypJiysoides Crouan ; Solms. Monograph of the Acetabularieae p. 29, pi. iv, figs. 2, 6 ; Howe Phycological Studies IV : the genus Neomeris and notes on other Siphonales p. 92, pi. 6, f. 16-20, pi. 7, f. 5-9. Our plants (only few in number) have rather thickly encrustated disk which is very shallow and though inter-radial lime-mass is shorter than the rays, their free margins are more or less encrusted (wood- cut fig. 2). Sporangia (rays) 12-16 (mostly 1 6) varying from intlated- obovoid and twice or a little more times as lone as broad to clavato- o cylindrical and thrice or a little more times as long as the greatest wideth ; coronal processes knob-like, oval or a little longer in radial direction, 67x75,^ (in one which I have measured), each bearing (4?) -5-6 hair-scars arranged in elliptical manner; hypopeltal process wanting ; aplanospores globose or ovoid or somewhat elliptical (in one I have measured go/* in diameter) ; stipe usually much corrugated and enlarged in the upper part, measuring 0.5 mm. in the thickest part.

Fronds caespitose, filiform or linear, rising from fibrous roots, ancipito-compressed or almost flat, densely branched from near the base in 3-4 times pinnate manner. Branches alternate, opposite or irregularly set, patent, often slightly flexuose ; the lower ones are longer than the upper, becoming gradually shorter above and similarly loaded \vith lesser sorts of branches in turn. Ramuli short and pointed and often furnished with ramelli. Plants attain the height of 10-25 cm> mostly 10-15, with the breadth of 0.5-2 mm. Tctrasporangia are produced in an elongated or roundish oblong sorus formed on the upper portion of a ramulus. Cystocarp swollen beneath the apex of a ramulus either terminated with a simple or more or less branched apical portion of the ramulus. Colour shinin-T purplish red. Substance cartilaginous, somewhat membranaceous in thinner and broader ones; the fronds do not adhere to paper in drying. Hab. : On the rocks and stones extending from tidal marks o to the depths of 14 fathoms in the Pacific coast and to about 5 fa- thoms in the Japan Sea. Keerun (Taiwan); from the east and west coasts of Kyushyu to Kinkwasan ; coast of the Japan Sea ; western coast of Hokkaido. In Chosen at Saishutu, Fusan, Kokuzanto (14 PL. CVI— CX, " fathoms), Ursan, Seikoshin. Friuts : spring to summer. Length of the frond, breadth of the branches, shape of the tetra" sporic rainuli, habit of the branches and substance of frond much vary according to specimens. Branches are usually very patent, while in others more erect ; in some, breadth of the branches vary according to portions, and broader segments suddenly taper to filiform ones. The variation of breadth of the branches may in some measures be seen from the illustrations given. Tetrasporic sori are mostly formed in spatulately expanded ramuli, while in others in smaller roundish knob- like swollen apices of rafmuli. Substance is firmer in thicker or sub- cylindrical and slenderer frond, and is somewhat membranaceous in thinner and broader ones. The variation of substance originates from the differences of the localities of plants. The present plant grows in more or less sheltered places extending from the midtide to the depths of 5-14 fathoms and those growing in calm places are softer than those growing in the place where tidal currents are in a good flow. As the plant has a very wide distribution in this country the general aspect often so much differs that one may take some of the specimens for a distinct species. The alga is perennial and during one year it makes the growth of 10-13 cm., though the rate of growth differs according to the con" ditions of the environments. In this country the present seaweed is argely used as the material of " Knnten " that is well known seaweed jelly. PL. CVI.

Fronds caespitose, erect, rising from a scutate disc (?) with fibrous roots, 15-20 cm high, more or less stupose at base, tapering below into the stem, from which (chiefly from the both sides) filiform stolonlike segments are emitted which grow up into new fronds, clicho- — 34 — tomo-decompound, with erecto-patent branches standing on roundish axils, forming the flabellate outline when spread out on paper. Branches more or less pinnately arranged in an alternate manner with terminal or ultimate segments ending in a little expanded obtuse and slightly emarginate apices. Segments broadly linear, a little expanding in cuneate form beneath forks, 3-7 mm broad, sometimes 10 or more. Margin entire and thickened as if bordered. In the cross-section of frond, cells of the internal layer at the marginal portion are thickend and many layered, instead of being one. Cells of the internal layer are subequal in length and being arranged in somewhat transverse rows, they appear in the surface view as if transversely striated with curved lines extending between both margins. Tetraspores densely scatter- ed over the surface of frond leaving marginal portions sterile, but in some specimens they are seen somewhat to form irregular patches. Colour greenish brown when young becoming more yellowish and darker when old. Substance thick membranaceous and the plant does not adhere to paper in drying. Fruits in summer. Hab. : Futae in Amakusa I., Cape Nomo and Hirado (Prov. Hizen), Shinhama (Prov. lyo), Enoshima (Prov. Sagami), Onahama (Prov. Iwaki), Kinkwazan and Karakuwa ( Prov. Rikuzen). A new species under the subgenus Slrigocarpus perhaps to be ranked in the vicinity of Dictyota pinnatijida Kuetz. It is easily dis- tinguished by its having thickened margins and stolon-like radical filaments. Though the ramification is more or less dichotomo- pinnate, yet some have an appearence much resembling Dictyota dicho- toma (Huds.) Lamour. PL. CVIII, fig. 9.

Fronds more or less stupose at base, coespitose, rising from a scutate disc, narrow or broadly linear, flat or torted, dichotom- ous or dichotomo-pinnate, more or less expanding with erect or patent elongato-cuneate segments, with margins entire or loaded with proliferations, widely parted or emarginated at apices, ending .n roundish-obtuse segments. Sori densely spread over both sur- faces of frond leaving narrow marginal portions. Tetragonidial sori elliptical at beginning, afterward becoming irregular in shape by growing together. Oosporic sori minute dot-like and equally scat- tered over both surfaces. Colour yellowish-green or more brownish. Substance thin and membranaceous and plant imperfectly adheres to paper in drying.

Size of frond, habit and breadth of branches, mode of ramification, characters of terminal segments etc. much vary according to specimens from different localities. But as it is difficult to separate one from another as a distinct species, there being several gradations from one form to another, I think all those variations as the dif- ferences of forms, consideriug that many diffterent species illustrated in Kuetz. Tab. Phyc. /. c. are put under one species as the forms of Dictyota dicJiototna. Those forms which I took for the typical one have more or less flabellately expanded regularly dichotomous frond, having mostly erect, entire and flat (/. e. not torted) segments, ending in blunt and einarginate apices with the breadth of segments varying from 2 to 10 mm. (mostly 5-6) and 10-15 cm. in height (PI. CXI, fig. 1-3). From those forms there are some deviations among the typical ones in torting of segments, spreading of parts and taper- ing of apices (PI. CXII, fig. 2-3). In some specimens proliferations are produced both from margins and surfaces (PL CXII, fig. i, 7). In robust ones fronds often attain the height of 30 cm. and epidermal cells are here and there (mostly at margins) seen to be transversely divided into two. They are thicker in substance and have darker brownish colour than usual forms which have thin membranaceous substance and light yellowish-brown colour. Those robust forms let us remind our Pachydiclyon coriaceum which how- — 4' — ever differs in having still darker colour, more thicker substance, erect emarginate apices and hypodermal cells. In some fronds as illustrated in PI. CXII, fig. 3 (from Cape Nomo) basal portions are stupose for a distance of 4-5 cm. from the root. In the next place there is one which I took for f. implexa. It has the frond of mediate size which has upper segments torted and interwoven, being dissolved into slenderer branches from the lower broader portions. In the specimens now before us such fronds attain 6-1 1 cm. in height with the breadth of 2-3 mm. at lower portions in dried specimens and tapering above into 0.3-1 mm. in breadth. Terminal segments are erect, obtuse and emar- ginate as well as widely parted and more tapering. In one and the same frond those different characters of terminal segments are often observed as illustrated in PI. CXII, fig. 4-6. Lasty, there is still another form which has branches more or less pinnately arranged. Of the plant of this form, there may be distinguished some two variations. As I have illustrated in PI. CXIII, frond has an appearence much differing from the typical form having elongated and straight rachises on both sides of which lateral dichotomous branches are pinnately arranged. These forms which have broader segments are seen along the Pacific coast of this country. Another one has more or less flexuose branches having a flabellate outline, and of this form apical segments are either blunt and emarginate or more acute and parted. Those forms are mostly found along the coast of the Japan Sea and they have narrow linear fronds. Of fructifications some remarks must be given about the arrangement of sori of oospores and tetragonidia. The former are equally scattered over both surfaces as minute dots except narrow marginal portions, while the latter are produced forming an — 42 — elliptical sorus, at least at the beginning, as it is seen from those formed in terminal segments. They become gradually confluent and in some irregularly roundish sori are formed, while in the other more or less elongated linear ones are produced. Afterward they become more and more confluent and the whole surface excep marginal portions become equally covered with them. Such seems to be the" case in the fronds having broader branches. In narrower fronds, tetragonida are seen from the beginning to be densely scattered in elongated patches between both margins. PL. CXI. Fig. 1: typical form of Dictyota dichotoma (Huds.)

New or little known Algae from Japan (Bot. Mag. Tokyo Vol. IX, No. 106) No. i, PI. IX, f. 1-2. Fronds numerous from a common callous disc, each rising with a single stem, 7-20 cm. high, rarely 30 cm. or more, narrowed at its base, soon becoming compressed and afterwards preserving everywhere a nearly equal width of 1-1.5 mm- (rarely 3 mm. or more) till, approaching to the apices, it again grows narrower, and ends in a sharpish point. Stem is undivided at the base for a more or less long distances, then becomes divaricately dichotomous, the distance between the lower dichotomies being longer than that between the upper ones. Sometimes the ramification is more re- gularly dichotomous in somewhat flabellate manner, but more usually it is irregular, irregularities being assisted by divaricately decompound segments and by large secondary branches, which has developed from proliferations, either simply elongating or similarly dichotomo-decompounded as other portion of frond. In some speci- mens, segments expand somewhat beneath the forks, being slightly -analiculated. All the branches are beset on both sides (some few ones from surfaces) with proliferous ramuli, usually 1-2 cm. long, distichous, scattered, some standing nearer to each other in secund manner, others rather remote ; some remain simple and short, others forked. Proliferations are linear constricted at base, taper- ing at apex. Terminal segments often elongate. Structure of the PL. CXVI— CXX, December, 1913. - 56 - frond is that of the generic type and the cells are firmly coalesced. — Fruits of both kinds are formed in ultimate segments and pro- liferous ramuli. Tetraspores forming a subsorus in the median or terminal portion of ramuli, oblong, immersed among cortical fila- ments. Cystocarps here and there scattered in a few groups in terminal portion of frond and in proliferations. They are not found in older and lower segments. Colour dull purplish-green, becoming greenish-yellow. Substance cartilaginous, becoming firmer in drying. Plants do not adhere to paper in drying. Hab. : On rocks near high tide.

Affinities : The many times dichotomous frond of the present plant induces us to think of its relation with Gratetoupia dictotoma and by that characters it may be referred to the section Chondro- phyllum. With Gr. filicina, on the other hand, the present alga shows some relations, for there is, in some specimens (as I have illustrated in the larger one of the two figures in PI. CXVI), a very close resemblance in appearence between the two species. In such specimens, the frond is very much elongated and remains for a greater lengths simple ; then once or twice forks at longer distances, and the segments from the base to apical portion are beset on both sides with proliferous very elongated, simple or distantly forked horizontal distichous branches, either naked or clothed with lesser sorts of ramuli. One may easily take such forms for Gr. filicina, though dichotomous ramification is rarer in case in that species. The substance, however, is firmer and more cartila- ginous than Gr. filicina, and moreover, even in those specimens which have an appearence like that plant, tetraspores are collected — 57 — in proliferous younger branches not in older segments, while in Gr. filicina, tetraspores and cystocarps are equally scattered over the frond. Thus, the present alga seems to me to be an intermediate form between Gr. filicina and the section to which Gr. dictotouia and others belone. •&• PL. CXVI.

Fronds consisting of three layers of cells ; the medullary layer of loosely and longitudinally running filaments, gradually becoming denser outward ; the subcortical layer of roundish cells, which pass into dichotomous moniliform filaments of the cortical layer. Cells are firmly coalesced and the dried frond long resists the action of water in reimmersion. Tetraspores and cystocarps densely collected in ultimate ramuli. Neucleus is rather smaller than that of other related species and the filamentous — 61 — tissue surrounding the neucleus is more thickly developed than allied species. Colour vinoso-purple fading to yellowish. Substance cartilaginous and firm becoming almost horny in dried state. Plant does not adhere to paper in drying. Affinities : In habit the plant is allied to Grateloupia fiilicina, but widely different in consistence. The substance is more firm than Gr. divaricata Okam. with which the present plant shows some affinities. PL. CXV1I, Fig. i-u.

Diagn. : Fronds high, caespitose, linear, compressed, more or less stipitate, many times dichotomous, patent, bifid or emarginate, with simple or forked proliferous ramuli on both sides which are constricted at the base. Cystocarps and tetraspores collected in terminal segments and proliferous ramuli. Tetrasporic sori linear or linear-oblong. Filamentous tissue surrounding the neucleus is rather weakly developed. Substance is almost horny and the plant long resists the action of water. Hab. : On rocks near high tide between tide marks. Provs. Totomi, Sagami, Boshyu, Kadzusa, Hitachi and Rikuzen. Cysto- carps and tetraspores : summer. Descrip. : Fronds caespitose, rising from callous discs, erect, linear, compressed, 15-20 cm. high and 1-2 mm. broad, more or less stem-like below, many times regularly dichotomous, often flabellate in outline, patent, with lower dichotomies more distant than the upper and ending in bifid or emarginate blunt apices, with simple or forked proliferous ramuli, constricted at the base, arising from both sides of branches and from harmed ends. Struct- ure of the frond is that of the genus ; medullary filaments are more or less loosely set, surrounded by larger and roundish sub- cortical cells which are covered by dichotomous moniliform filaments of the cortical layer. All the cells are firmly coalesced and the plant long resists the action of water. Tetraspores and cystocarps are collected in terminal segments or in proliferous ramuli. Tetra- - 64 - spores are collected in linear or linear oblong sori. Carpogonial branches and auxiliary cells are formed at the base of the cortical filaments which descend below into the cavity produced in the subcortical layer. Auxiliary cells are single and conical in shape and are abundantly prepared. Filamentous tissue surrounding the neucleus is weakly developed. Colour vinoso-purple. Substance cartilaginous and almost horny when dried. Plant does not adhere to paper in drying. Affinities : Allied to Grat. divaricata Okam., *but more carti- laginous in the substance and the plant in question is the firmest oi the genus as is known at present. PL. CXVIII.

Japi Motsure-miru. PL. CXX, Fig. 9-13. Diagn. : Frond large, creeping, compressed with broader segments, irregularly and divaricately dichotomous, deep-green, intricated by attaching to each other with root-fibres here and there ; utriculi cylindrico-clavate, thin-walled at top, 5-6 times as long as broad ; gametangia elongato-ovate. Hab. : On rocks a little below low tide. Ryukyu, Prov. Hiuga (Yendo), Cape Nomo, Futae (Amakusa Isl.), Kashiwa-jima (Prov. Tosa, Shiihara), C. Shiwo (Prov. Kii), Hama-jima (Prov. Shima). Dcscrip. : Frond creeping, compressed, irregularly dichotomous divaricately branched, densely intricated by attaching to each other with root-like filaments here and there emitted from the under- surface of segments and forms, in well-grown fronds, a low heap (2-3 cm. high) of irregularly roundish outline covering the sub- stratum extending from 10 to 20 cm. Segments become gradually narrower toward extremities from basal broader portions where they attain 5-10 mm. or more in breadth. Utriculi cylindrical or cylindrico-clavate, obtuse or subtruncate and thin-walled at apex, sometimes a little constricted beneath apex. They measure 7 70- 1 1 50 1* in the broadest part, and 5-6 times as long as broad. Gametangia ovate. Colour deep-green. Substance soft to touch, and firmly adheres to paper in drying. Affinities: As far as I know, there are three already known species of Codiuin which has creeping habit, viz. C. dimorpltuin — 75 — Sved., C. repens Crouan and C. divaricatum A. & E. S. Gepp (non Holmes). Of them, the present plant seems to me to show some affinities with C. repens Crouan on account of the creeping habit and longer, narrow, ond clavate utricles of the latter as A. & E. S. Gepp mentions under Codium divaricatum A. & E. S. Gepp (The Codiaceae of the Siboga Expedition p. 136). Of that species, however, I know nothing but Vickers' description of it (Liste des Algues Marines de la Barbacle p. 56, no. 37). C. repens seems to be very slender as A. & E. S. Gepp mentions under C. divarication that the latter (which has segments 1.5-0.5 mm. broad in dried state), resembles the former species in dimensions (A. & E. S. Gepp 1. c.). Moreover C. repens is described by Vickers as tubulous (" tubuleuse "). Of C. dimorphnm Sved. there is no need to tell much of its difference from the present plant. Thus the present species is different from all of those three related species. PL. CXX, Fig. 9-13.

Plants more or less variable in habits and size, attaining the height of 15-30 cm. Fronds densely ccespitose rising from callous disc, linear, compressed, almost flat in some specimens, somewhat thickened in others in the median line and then ancipitous, and often in fully grown larger fronds the most parts of the lower portion of the frond become almost cylindrical appearing like the stem. Fronds forked more or less immediately adjoining the root and afterwards repeatedly divided at mostly short, but uncertain, intervals, in an irregularly dichotomous manner, with patent seg- ments besides which, scattered branches, between horizontal and patent, of most uncertain length, some simple, others divided, arise here and there from the side of the larger ones. Branches are in some slender and linear, (1-1.5 mm broad) in others more broad, and often especially so towards the forks (even 5-6 mm broad in dried specimens). The apices of all the branches and branchlets are as a rule slender and pointed, sometimes obtuse and truncated, more so in older fronds ; the margin quite entire, naked below, but towards the summits fringed on both sides (also proliferated — So — from both surfaces) with distichous, horizontal ramuli, 2-15 mm. long, placed close to each other, nearly cylindrical, either filiform or slightly thickened upwards and simple or branched ; some fronds are quite free from them. Cystocarps terminal on short, simple or branched, ciliary processes closely set on both sides of branches ; cystocarpic fronds are furnished with such short processes only. Colour brownish-red, turning to almost black in drying. Substance cartilaginous and the plant does not adhere to paper in drying. Hab. : eastern and western coasts of of Kabafuto (Saghalien) ; Isls.

Fronds numerous from the same base, 10-20 cm high, very weak, gelatinous, cylindrical, filiform, somewhat tubular, 1—1.5 mni- thick, each rising with a single undivided stem, lower portion sometimes naked or beset from base to summit with branches rather loosely disposed on all sides in alternate, sometimes opposite manner, 3-7 cm. long, the whole branches densely furnished with a series of shorter branches similar to them in every respect, and those again with simple, short, subulate ramuli ; the branches and ramuli are all between erect and patent, slightly attenuated at their bases, and remarkably acuminated at the apices. In the growing portion of branch, cortical cells carry slender, one-celled, hyaline, deciduous hairs. — Cystocarps dot-like, densely scattered and 'mmersed beneath the cortical layer. Colour pinkish-red, soon turn- ing to brick-red in decaying. Substance very tender, slippery, almost gelatinous, and the frond breaks down soon in decaying into pieces. Formation of Cystocarps. Procarp is formed as a branch of two-sidedly branching auxiliary cell-branch which is laterally- supported on the side of an infracortical filament arising verticil- lately trom the central axis. It consists of 3 or 4 cells, of which hypogenal cell is larger and laterally elongated. Auxiliary cell is prepared as a larger, roundish, intercalary cell beneath the curved apex of auxiliary cell-branch. Spore-filaments are produced in a paniculate manner either from fertilized and non-fused auxiliary cell or from fused cell which results from the fusion of an auxi- liary cell and sterile cells adjoining it. Even when auxiliary cell — 38 — does not enter into fusion with other cells, they become almost empty in their contents. Neucleus is simple, globular mass( covered by slightly elevated cortical layer on that part. Hab. : On rocks between tide-marks near high tide. Prov. Hizen, Prov.

Frond epiphytic on larger algae, tufted, erect, cylindrical, throughly corticated, tapering and rooting at base, 6-n cm high in sterile frond, 2.5-5 cm 'n fructi- fied plant. Ramification is more or less irregularly and divaricately pinn'ato-decornpound. Branches arising on all sides, alternate, here and there subsecuad, much elongated in sterile plants, usually branching toward apex and the whole ramification is in some measure corymbose. In plants bearing cystocarps, branches are not so elongated as in sterile fronds and are similarly branched toward apex in subcorymbose manner ; and the whole frond is densely clothed with short, subulate ramuli, which often arise fas- ciculately. All the sorts ot branches are very patent, more or less constricted at base tapering to apex, which is straight, never being lorcipated. Tetraspores immersed beneath cortex, verticillately around the node of unaltered branches, afterward scattered. Cystc- carps sessile along the side of ramuli, single or often two seriated longitudinally along the same side of longer ramuli ; neucleus, surrounded by 5 or more involucres which are not much longer than neucleus- Articulation subequal as the diameter in the main portion, l/2-l/i shorter in basal portion of frond and in ramuli ; node neither constricted nor prominent. The cortical cells consist of two layers ; the inner, of larger roundish cells, while the outer, of a few layers of smaller cells. Color blood-red or purplish red.

Descrip, : Fronds high, often 30-40 cm, usually 15-20 cm long, caespitose, linear, ancipito-compressed, rising from fibrous roots, much branching a little above the root in 3-4 times pinnate manner. Branches of every order are alternate or opposite, very patent, longer and shorter mixed ; shorter ones appear as if ramuli which are furnished with simple or branched ramelli and longer ones are again pinnated in the similar manner as other branches. Larger branches are slightly flexuose and terminal portions are somewhat naked. Fruits of both kinds formed in ramelli which are often aggregated. Tctrasporic sori are produced in roundish, ovate or oblong, more or less expanded ramelli. Cystocarps are — IOO — swollen beneath the apices of ramelli, either terminated with a simple, or branched, pointed or expanded apical portion ; often two cysto- carps are formed in a discontinuous longitudinal row in one ramellus. Colour shining purplish red. Substance cartilaginous and the plant does not adhere to paper in drying. The alga is perennial and during one year it makes the growth of 1 8-2 1 cm. Of duration of the life of this alga we know nothing. Of the anatomical structure, the frond consists of three layers, cortical, infra-cortical and medullary (PI. CXXVII, Fig. 9, a, b, c). The hyaline filaments which are characteristic for the plants of this genus are very dense in the infra-cortical layer and more loose in the medullary. The structure is just same as that of Gelidium ainansii Lam. Affinities : The present plant has been taken by early authors for Gelidium cartilagincum Grev. (e.g. Harv. in Gray's List of Jap. Plant no. 13, collected at Shimoda) from the resemblance of the flexuose habit of branches, and of cystocarpic and tetrasporic ramelli. But the mode of ramification is very different in two plants. In Gclidinm cartilagincnin longer and shorter branches do not stand mixed, and the pinnate arrangement of branches is more regular than in ours. Moreover the frond of the former is much larger and more stout, and branches are broader and thicker than the present plant ; also branches (which are more widely patent as al- most horizontal) are a little narrowed at their bases. Gelidhim pacificiim, on the other hand, is more robust than G. amansii Lam. with which it is so closely allied that both plants are often confused, and the both grow in the same locality ; but the former prefers the habitat where waves are strong or tidal currents are in a good flow, while the latter is found in rather calm places ; I — lor — and so, the former is often found in a projected point while the latter in sheltered places. Fronds of the former are much larger than those of the latter and the branches are much broader. Tetrasporic ramelli are more or less expanded and roundish in G. pacificum, while in G. amansii, linear or linear-oblong. Again, cystocarps of the former are terminated with somewhat expanded apical portions of ramelli and not so long and slender as in the latter. Also in the plant in question both tetrasporic and cystocarpic ramelli are more or less aggregated, while in the plant taken in comparison they are loosely arranged. PL. CXXVI.

Basal por- tions of the primary branches are naked or provided with a few hamatous simple or divided ramuli which are also scatteredly found along the main segments. Pinnae alternate and linear in outline, patent, densely pinnulated on all sides. Pinnules or ramuli short, erect or erecto-patent, subulate, simple below, multifid above, and often recurved. Articulations 4-siphonous and throughly ecorticated »' length of articulations of the main segments 6-8 times as the diameter, that of pinnae subequal to or a little longer, and that of pinnules lint is ramuli, as half as the diameter. Telrasfores found in fusiform stichidial ramelli densely arising in clusters in the axils of ramuli, 3-4 arranged in a longitudinal row. Cystocarps borne on the upper ramuli, urceolate with a wide ostiole, slightly crenulated at the margin and almost sessile. Colour brown, becoming almost black in drying. Frond does not adhere to paper in drying. — IDS — Hub.: Riishiri (Faurie, Herb. Mus. Paris no. 9732, leg.

A very distinct and handsome species closely allied to P. urceolata Harv., as Harvey remarks in Harv. l.c, but the ramifica- tion is very different. I have studied a specimen of this species from Prof. Farlow's Herbarium kept in the herbarium of Tokyo Imp. Univ. which is found with stichidia forming clusters in the axils of ramuli as it is natural for this species. Kiitzing's illustration which shows tetraspores borne in usual ramuli instead of in the ramelli standing in the axils of ramuli is at variance with our observations. PL. CXXVII, Fig. i-S.

Clavigera (Harv.) Yendo 1. c. PL. CXXVIII, Fig. 2-3. Cystopliyllum fusifonne ft clavigerum Harv. 1. c. Root a small holdfast with robust, cylindrical rhizines. Stan erect, cylindrical, branching in 2-3 times pinnate and alternate man- ner. A few radical leaves or " rami," as they are called, are present near the basal portion of the frond. Leaves are deciduous and are always observed in very young individuals only, They are compressed, thick and fleshy, of ovate, clavate or linear-spathulate shape, more or less tapering upwards, pointed or rounded at apex, coarsely dentate at the upper margin and provided with a short cylindrical petiole and cryptostomata. The rami, as they are called, very much vary in shape. In some they are short and clavaf.e with the apical portion inflated into a pyriform vesicle. In others they are several inches long, solid, cylindrical, with equal thickness throught the whole length, except towards both ends, where they become somewhat slender. Often some "rami" become clavate, complanated above and toothed, thus assuming the appearence like leaves ; such forms seem to me to be more common in the southern plants. Vesicles are either mucronated or tapering upwards or fusi- — 110 — form, and sometimes they are furnished with leaf-like wings as in PL. CXXVIII, Fig. 3. According to Mr. Yendo the plants from colder seas are rich in the clavate " rami " while in those from warmer regions the " rami " on the principal members are mostly filiform. The former coincide with the definitions of var. davigvrum H irv. But this character is invalid as Mr. Yendo remarks and many intermediate froms between both extremes are met with. Branches when young are stunted standing in the axils of the "rami " and are beset with several ramuli in a spiral arrangement, thus as- suming the appearence of subfasciculate bunches at the axils ; they gradually develop into branches and fulcrant " rami " are dropped off. This prolongation is restricted to the primary branches only and those of the next order do not elongate. — Receptacles (diaeci- ous) are oblong or clavato-cylindrical with rounded apices, clustered in the axils of the "rami." "Colour olive brown. Substance succulent and the plant imperfectly adheres to paper in drying. Frond when fully grown often attains the length of one meter, but usually about 30 cm. long with the diameter of 3-4 mm. in the thicker portion. Branches are mostly short, but some are 5-10 cm. long. The plant is diaecious and perennial, but the original or primary frond seems to wither yearly and before it dies the plant shoots out short branches like stolon from the basal portion and on that stolon young fronds are developed. In this country the plant is gathered by people as food material and on this account the duration of life is not easy to make clear. Hab. : gregarious on rocks below high tide; very common along the Pacific coast from Kyushyu to Prov. Rikuchyu ; also Tsu- garu str. ; Toppu, Zenigamezawa, Fukuyama, Hakodate (Prov. Oshi- ma, Herb.

Only one specimen now before us. Frond rising from a circular disc, linear, with the midrib thickened below into a short stem-like, winged portion, 6.5 cm. high, 4-6 mm. broad, flat, undulated and serrato-dentate at margin. The midrib more or less thickened for the most part becomes fainter upward, with very patent and faint veins extending alternately from the midrib to marginal teeth. Branches standing in 2-3 times pinnate and alter- nate manner, arise from margins as well as proliferate from the midrib and are slightly narrowed at the base, ending in roundish- obtuse in-rolled apices. On unfolding the inrolled apex of a branch, the growing apices of lateral branches and finger like young marginal teeth are displayed, all of which are strongly incurved to the ventral side of frond. Marginal teeth become obsolete in the lower portions of branches or assume deltoid shapes. When young they are fine and subulate, strongly involuted, scarcely i mm., long in the longest one, and in a fructified frond stichidia are produced in them. Stichidia formed in pinnules of pinnately lobed and siibmultifid teeth, linear, containing a double row of tetra- sporangia. The midrib is much thickened on the ventral side, to- ward which curve the apices of branches and marginal teeth. On PL. CXXXI— CXXXV, February, 1915. — 124 — the dorsal median line of every young segment, for instance of marginal teeth, a single row of dichotomous "hair-leaves" is longitudinally arranged. The cortical and inner cells covering the midrib portion of the upper part of a branch are elongated, while those of the remaining portion are irregularly polygonal. On the cross-section of frond through the midrib 5 pericentral cells are observed, of which the unpaired one stands on the ventral side and the paired ones on both flanks. Colour vinoso-red.

Fronds csespitose, filiform, 1-1.5 mm- thick, elongated, rather harsh to touch and fragile, of dark greenish blue-violet colour, laterally branched, capillary-fine in young branches, becoming unequally thick in older portions, with globular or depresso-globular central cells in fully grown portion, with articulations not exter- nally constricted, thinly corticated (2-cell-layers thick), afterward becoming hollow by the decaying off of the axial cells when the branches attain the thickness of some 400 p in diameter.

Descrip. : Fronds densely tufted, filiform, about. 1-1.5 mrn- thick in the lower portion of a thickened frond, elongated, often 30 cm. long, usually crooked and somewhat entangled at the lower portion. Plants have a more or less traceable main segment and 2-3 times branch laterally in an alternate manner; younger bran- ches are capillary-fine and those standing at the lower portion of frond become somewhat thickened like the main segments.

Born, et Flah. ?9. Fig, 1-13, >^ ?>). Fig 14-17. 129 — branches consist of a single longitudinal row of disc-shaped cells and the plant makes its growth by the terminal as well as inter- calary cell-divisions. The articulations are ^2-^/3 as shorter as the diameter ; soon longitudinal partitions are formed near margins, giving rise to the central and cortical cells. By further divisions a cortical layer is produced covering the central cell. As the branch grows in length the central cells increase in size, and as it thickens it becomes unequal in thickness being bullato constricted at short intervals. Cells of the primary articulation now become almost globular or slightly depressed and those of the cortical layer are either undivided or here and there divided into two. In this stage the central cells are scarcely visible through the cortical layer and the articulations are not externally constricted. As the frond attains a thickness of some 300-400 ,« in diameter, the central cells show a tendency to be destroyed and in a thicker portion measuring 500-750 tl there is no remain of the central cells leaving the interior of frond hollow. The fully formed cortical layer consists of two layers of cells, of which the inner is larger and roundish, while the outer is smaller and anticlinally a little elongated. Cortical cells are not elongated in surface view, but irregularly polygonal and closely disposed. They contain a distinct neucleus and many roundish-angular chromatophores, while cells of the inner layer are almost empty and colorless. On account of the fragile substance the frond becomes, as the plant grows in age, rather naked by dropping off of branchlets and apices of branches become bluntish. Monospores (aplanospores) are formed in monosporangia which are produced either directly from a cortical cell or from a cell — 130 — produced by horizontal or oblique partitions. They contain very deeply coloured content and a neucleus. The development of the plant from the monospore is quite same as that observed by Mobius in C. chalybcus. Kuetz. The mono- spores which have been set free probably just to germinate measure 0.015-0.02 /". in diameter. The young prothallium which I could obtain on a leaf of I'alisncria spiralis consisted of 4 cells, of which the larger central one has cut off a cell by a horizontal partition (PI. CXXXIII, f. 10). After that there is formed a somewhat radiately branched flat disc which adheres to the substratum. The prothallium which is single- layered at the beginning now becomes parenchymatic by repeated cell-divisions and a flattish low mound like body is formed. When the prothallium attains the size of some 130 it, some of cells of the upper layer form branches directed upward. They consist at first of a single row of cells. Larger prothallium, more numerous the number of vertical branches. As they grow in length, the lower cells cut off a cell at the lower corner which elongates into a root-fibre. Root fibres which are articulated run in both intra- and extra-cortical ways and by coa- lescing together form a somewhat conical holdfast. When the ver- tical fronds are firmly established the prothallium goes down to the ground. After that, originally single row of cells of a young frond becomes two layered in the manner above stated. Colour dark "reenis'n-blue violet. Substance fragile and somewhat harsh o o to touch ; when dried, the plant does not adhere to paper. There is no doubt that the present plant has a very close affinity with C. cocnilcns (Balb.) Mont, as the size, thickness and colour show its resemblances. Of the anatomical character of the latter much is not known, as far as I am aware, except Kuetzing's description and illustrations (Kuetz. Sp. Alg. p. 432 and Tav Phyc. VII, t. 88, f. II.) and Thaxter's recent investigations (R. Thaxter Notes on the Str. and Repr. of Compsopogon in Dot. Gaz. Vol. XXIX, P. 259-267, pi. XXI, 1900). Kuetzing illustrates 3 cell-layered cross-section of the frond without central cell. He does not clearly mention that the frond is hollow, only stating that ,'articulis in ramis primariis obsoletis." Whether this statement means that the frond is hollow or not is not clear. But Thaxter describes and illustrates that " the corticating cells are separated into two well-defined layers which may be increased to 3 or even 4 in older axes like that shown in Fig. 13, a portion of the axial cell being indicated at x" (Thaxter I.e. p. 262). Consi- dering that Thaxter's material is C. coentleus, it is evident that it has thickly corticated frond with a central cell persisting. Such a structure is not the case in the present plant ; in ours the cortical cells are not more than two layers in the branches thicker than 400 n and in the branches of such a thickness the central cells are already disappeared. De Toni's remark saying "cellulae corticales e superficie visa? sunt elongatae, irregulares, acute contiguae " and Kuetzing's illustration representing regularly arranged elongated cortical cells are disproved by Thaxter's description and illustra- tions (i.e. " the corticating cells are irregularly polygonal "). Thus, the present plant differs from C. coentleus, as far as I can judge from the literature concerned by the brittle substance, by disappearing of the central cells in older portions and by fewer cortical layers as well as by slenderer habit of the frond.

Diagn. : Fronds a little stiff, decumbent, compressed, broadly linear, irregularly dichbtomous with obtuse, truncated or bifid apices — 142 — and roundesh axils, attaching to each other and to the substratum by emitting root-tufts from the undersurfaces, of deep greenish colour. Utriculi almost cylindrical, subtruncated at apex and slightly narrowed a little beneath the top, 50-66 n broad, about 366 n long, 5-6 times as long as broad ; utriculi of the undersurface having a very thin wall at the top, those of the upper side a little thickened and those standing at the corner or margin thicker than those of the upper. Hab. : On rocks below low tide. Provs. Boshyu and Sagami. Descrip. : Fronds decumbent measuring some 10 cm. or more in extension, with broader segments, 5-10 mm. or more in breadth I 3-4 mm. thick, which are parted with a patent axil, closely coa- lesced to each other by short tufts of reot filaments emitted from the under-surfaces of segments, with glabrous surfaces on both sides. Utriculi are generally slightly constricted a little beneath the apex. This character, however, is not strictly followed ; for, in one and the same frond some are not constricted; but subtruncat ed character is almost uniform. Utriculi branch near their bases close to each other after the manner of Codium adhaerens so as to form a dense compact layer and to extend side by side rather than to increase in thickness. Utriculi of both upper and lower sur. faces are not much different in the thickness of the terminal wall i but strictly speaking those of the upper side is a little thicker than those on the lower ; those standing at the corner or margin of frond have a thick wall at top, but not too much thickened like crescent. Colour deep green. Substance rather firm becoming somewhat coriaceous when dried and the plant does not adhere to paper in drying. — 143 — The present plant shows on the one hand a close affinity with Codiinn mtricatiim Okam. (p. 74, PI. CXX fig. 9-13) and on the other some relations with C. dinwrphum Sved. With the former t has the following characters in common, viz. : dichotomous, com- pressed and decumbent habit, characters of emitting tufts of root- fibres and shape of utriculi ; but it differs in the substance and colour of frond, as well as in the size and apical thickness of utriculi. The substance of C. intricatnm Okam. is more soft, the plant firmly adhering to paper in drying. The intrication of parts is more dense, and colour is light greenish. Moreover, the breadth of utriculi is broader than the present plant and they do not present any difference in every part in the thickness of apical wall. With C. dimorphnm, in the next place, the plant in question shows some similarity in having thickened wall of utriculi differing accord- ing to their positions ; but the thickness is thinner in ours than in that plant. Of the difference of shape of frond between two plants it is so evident that there is no need to relate much of it. Indeed, the new species stands near C. intricatnm Okam. under the Agardh's group of Codia elongatae. PL. CXXXIV, Fig. 4-12.

Hab. : At the depth of 2-3 fathoms. Provs. Hyuga, Satsu- ma and Hizen, Amakusa Isl., C. Shiwo (Prov. Kii), Prov. Shima. Desci'ip. : Fronds globular, ovoid or obovoid when young 2-3 cm. in diam., or irregularly protubelant from the beginning ; as they grow in size, some become uniform below, some extend more or less laterally or more and more becoming irregularly proliferating or variously sinuated or tuberous, attaining the size of 7-9 cm.- in height and breadth. Fronds seem to grow on gravels stones, corallines etc. by emitting root-filaments either from one spot of the undersurface or from several flecks and as they increase in size, rooting flecks are increased in number. On cutting the frond into two, the peripheral portion incurves with a strong force. Frond is not hollow within, but solid, the inner cavity being densely filled up with hyphoid filaments running downward from cortical utriculi and with abundant mucilaginous mass. Utriculi are slender cylindrical with a thin-walled globular top, ca. 2 mm. long with an average breadth of iSS ,u and 7-10 times as long as broad. They branch in the midway or a little below ; and from this mode of ramification it may be inferred that the frond grows in size on all sides. The surface of irond is velvety and the substance is firm and compact, very gelatinous to touch and the plant firmly adheres to paper in drying. Colour herbaceous green with shining lustre in drying. — 149 — Among our plants the present alga is related to Codium mamiUosum Harv. in shape, but from which it differs in size and irregularly protuberant shape of frond as well as in the form and size of utriculi. Codium pomoidcs J. Ag. (Anal. Alg. Cent. I, p. 100) which seems to me probably to have been known only in young stages seems to resemble very much to the present plant, especially in its very elastic habit and long cylindrical " aciculaeform " utriculi. But shape of the frond of that species is said to be regularly globular and the length of utriculi which are slightly constricted beneath the apex, unlike in ours, is much longer than the plant in question (" decies aut fere usque vicesies longioribus "). Of their breadth nothing is mentioned. Thus on the ground that the present plant differs much from C. mamillosum and somewhat from C. pomoides I establish the present plant as a provisionally new species. PL. CXXXV, Fig. 6-9.

Branches are more or less compressed often subcylindrical in upper segments as well as in stipital portion, patent, with round axils and are broadly expanded beneath forks into flat and cuneate segments where the breadth often measures 6-13 cm. The dis- tances between forks are usually longer in the median portion of frond, gradually becoming shorter above and below often attaining 30 cm. or more in a well grown frond. Apical segments are divaricated or simply elongated gradually tapering upward into blunt apices. In some specimens very irregular ramifications are met with. Ulriatli are as a rule cylindrical, in some slightly clavate or obovate, and generally somewhat truncated at apex with thin apical wall when young, but afterward becoming much thickened. They are 658-846 /* long and 6-S times as long as broad. Gamct- angia are grown upon utriculi at about their middle portions or rather below, but not without those arising higher and measure 450 ," by i So it. Colour dark saturated green. Substance thick and PL. CXXXV— CXL. May 1915. - i56 - tough and the plant firmly adheres to paper in drying ; the frond strongly contracts taking a channelled appearence when dried. Hab. : On rocks near low tide extending to deep tide. Kago- shima, Nagasaki, Hirado, Cape Nomo, Prov. Tosa and lyo, Eno- shima (Sagami), Prov. Boshyu. The specimen by which Holmes founded the present species is probably a young form and he measured the length of utriculi as only 3 times as long as broad. He took it as one of the characteristics distinguishing C. divaricatum from C. clongatniiit but it is not so short as he mentioned. The present plant has a very close resemblance with Carftiun elongatnm Ag. in the external appearence. To me the difference between the two related plants seems to exist in the form of utri- culi and their apical thickness. Utriculi of the present alga is cylin" drical with subtruncate apex whose wall is more or less thickened and especially in older specimen or in older portion of a frond. The apical wall is much thickened as shown in PL. CXXXYI, fig. 3 ; while in C. elongation they are obovato-clavate with round and thin-walled apices. I have not been able to ascertain the size of a fully grown frond of that species in the literature consulted, but in our plant it attanis 90-100 cm. in length. C. clongatum Ag. has been reported to occur in this country by early authors, such as Suringar, Kjellman etc. Amongst others Kjellman reports this alga to have obtained at Cape Nomo giving an illustration of an utriculus (Marina Chlorophy. fran Jap. p. 35, Tab. 7, f. 4-5). In my specimen get from the same locality I find some of utriculi to be obovato-clavate somewhat resem- bling those of C. clongatnm, but in the same frond cylindrical and — 157 — subtruncated utriculi predominate. To me, at the present knowledge, the existence of that species in this country seems to be somewhat doubtful, if Holmes' C. divaricatum is surely different from C. elongatum Ag. and not the same species, I do not doubt that my plant in question is C. divaricalum, though I have not seen his specimen. The specimen (No. 25) which I sent to De Toni under the name of C. elongatum with the Japanese name " Naga-miru " is indeed the present species. The Japanese name given to that species is erroneous owing to the confused using for this plant and C. cylindricion Holm. In my herbarium I have a specimen of C. elongation Ag. from Brasil sent to me from Mr. Reinbold. In making study of this specimen in comparison with our plant I have found that the difference between the both plants exists in the form and apical thickness of utriculi. Is it not fact for C. elongatum Ag. that the dried frond is thin and soft owing to the thin-walled utriculi, while in C. divari- cation Holm, thickish and stiff on account of thickened apex of utriculi ? /. hybrida Okam.

VI, t. 17, I, and many other forms. Fronds gregarious, elongated, flat, thin-membranaceous, linear, linear-lanceolate or oblanceolate ; entirely simple or so for the most part excepting the lower portion of frond where a few branches are often proliferated. They taper strongly below, un- dulated or flat at margin, more or less wrinkled on the surface, often twisted or longitudinally folded, 10-50 cm. long, 0.5-15 cm. broad. When young, the frond is filiform and tubular ; but in such a young and slender one as measuring 1-1.3 mrn- 'n diameter throught, the inner cavity is here and there interrupted by the union of the membrane. In more broad frond the membrane is for the most part united except marginal portions where the in terior of frond is left as a hollow space and also a few cavities are here and there left in the median part. In fully grown frond, hollow space is not found but in the stipe and marginal portions, the membrane of remaining portion being united after the manner lof Ulva. Cells of the stipe are clavate, vertically inserted and sub-seriated ongitu^ inally ; those standing a little above are elongated poly gonal and arranged in a longitudinal direction. In the upper broader portion, cells become smaller and irregularly disposed. The inner wall of membrane is somewhat thicker than the outer wall at marginal tubular portion. Cells in a cross section of frond - i65 - are subaequal to breadth or i}4-2 times as high as broad. Gametes are formed in the cells of the upper portion of frond. Colour herbaceous green. Substance thin ruembranaceous. Hab. : On stones and wood works, left bare by the tide. Widely distributed. Several forms are met with, of which forma crispata, with edges much crisped and folded, and forma lanceolata, with edges even or plicate, not crisped seem to be more common. In one or the other of these forms the species seems common mostly on the Pacific coast of this country. It is abundantly found in winter and spring usually in brackish water in calm, places as Tokyo bay. PL. CXXXVIII. Fig. 1: fronds of Enteromorpha Linza (L.) J.

Fronds small, weak and filiform with a short not-well-defined (not as is usual for other related species) surculus, attaining a height of 1-2 cm. being- Ca. 100 /< thick. Only one or two fronds arise from an extremity of the surculus which is unequal in the thickness, being here and there swollen at longer or shorter intervals and root fibres are mostly emitted from the swollen portions. Plant branches divaricate-alternately and branches are loosely closed with ramenta. Ramenta are typically distichous and opposite ; but this regular disposition is disturbed by the presence of some irregularly inserted ones. They are separated by wider distances and the rachis is distinct!)- visible through the interstices. They are oblong or cbovate, being slightly swollen upwards, and are neither falcate nor pointed, but very patent, straight and very obtuse at apex. The bases of ramenta are sometimes equally broad or a little narrowed as if pedicellated. Ramenta attain in a fully grown frond a length of 216-354 /-<; the shorter one half that amount. The breadth is almost equal to or a little thicker than the diameter of the rachis in swollen ones, being somewhat slender in the more cylindrical ones. The portion of rachis intercepted between two opposite ramenta is slightly constricted as if articulated; it is more especially so in frond bearing ramenta constricted at base. In frond bearing ramenta which are not narrowed at base, the constric- tion of rachis is not so marked. Ccl.n- bluish green. Substance soft and thin membranaceous.

The fronds are broadly linear or lanceolate, 50-83 x 1 5-30 cm. simple or simple-pinnately branched, densely rugulose, roughly toothed at margins, cuneate or roundish- ovate at base. The stem is cylindrical, 13-23 cm. long, 3-5 mm. in diameter, solid, furnished with more or less irregularly set double rows of mucilaginous lacunae. The root fibres are verticillately arising, some of which elongate into stolon, at whose apex a young leaflet is formed and grows up into a new frond. The primary frond decays down during autumn more or less toward the base of lamina, where a new lamina grows up during the winter, which takes the place of the lamina of the preceeding year after the manner of Laminaria saccharina or L. Clousfoni. From the existence of double modes of the vegetative reproduction, the formation of zoosporangial sori seems to be suppressed. In the cross-section of stem a ring of mucilaginous lacunae is seen half-way between the cortical portion and medullary layer and another ring of smaller and more irregularly scattered lacunae is situated just beneath the epidermal layer. Besides these two rings, there is often present a portion of another ring near the medullary layer. In lamina a layer of small roundish lacunae is situated near the epidermal layer of both surfaces and the thickness of the medullary layer is just the same as the breadth of cortical PL. CXL. K.

Strait of Hirado (Prov. Hizen), Wajima (Prov. Noto), No (Prov. Yechigo), Avvomori (Mr. Higashi) ; Hanseiho and Zetsuyei-to near Fusan (Chosen). When the frond is quite simple, it is difficult to distinguish the present plant from Laminaria. But in the latter, as far as we know, marginal teeth are never present and they may be taken as a characteristic distinguishiug an Ecklonia from Laminaria. As the frond of an Ecklonian plant, as a rule, branches or divides pinnately, the marginal teeth may be considered as rudiments of pinnae when the frond is quite simple, as may be inferred from the homology between marginal teeth of frond and tooth-like be- ginning of pinnae formed on both sides of the growing portion near the base of the frond. Again rugae seem to be taken as another characteristic. In Laminarian plants, rugae (considering bullations or network-like wrinkles of the same meaning as rugae) when present are not equally spread over the frond after the manner of an Ecklonia, but usually are arranged, as far as I know, on both sides of the median fascia. {Laminarlia radicosa Kjellm. is, in my opinion, not a Laminaria, but perhaps an Ecklonia or a new genus, on account of the presence of marginal teeth, pinnate lobes and equally scat- tered bullations).

This is without doubt an error due to the incomplete specimens sent to him. It belongs to the section C. dongatii J. Ag. In the fresh state the present plant is easily discernible from the related plants by its colour, its brittle sub- stance and by its sufficiently large utriculi so as to give a granular appearance to the frond, each being perceptible even in naked eyes. In the herbarium specimens the deep-colored median lon- gitudinal zone is fringed by pale-green borders. The translucence of this border is clue to the existence of long and thick utricles. In pearl-oyster beds this plant often causes a fearful damage suffc citing oysters by piling up on it. PL. CXLI.

The frond arises from fleshy conical disc with a short thick tereti-compressed stem, expanding into cuneate or broadly rounded sometimes reniform base, with flat and entire margin, ending in simple obtuse or ligulate or sometimes bifid apices. The plants attain usually the length of 50-60 cm. in the breadth of 20-30 cm. and with the thickness of 1-2 mm. in the upper portion much more thick in the lower basal portion.

(Jotirn. of Botany Vol. 42, 1904) p. 162, Tab. 460, fig. 7,8). Solitary or a few fronds tufted rising from a scutate disc, filiform or cylindrical when old, provided with a more or less traceable percurrent stem, 20-30 cm. high, i mm. or more thick. Branches arise laterally on all sides in an irregularly alternate manner from near the base, elongated and are provided with lesser sorts of the second or third orders. The ramification is in some fronds more regularly alternate, in others more irregular between alternate and dichotomous. In some fronds branches of the fist order arise very near to each other, in others more dis- tantly. In some especially in younger ones, branches are much loaded with ramelli, while in others, mostly in older ones they become naked. The axils are wid^y parted or almost horizontal and the branches are somewhat flexuose. In younger ones bran- ches are soft and pliable, but become coriaceous when old. The frond is hollow with a small cavity in the centre. The axile cylinder consists of two layers of densely compacted cells ; the inner layer, of elongated cylindrical cells ; the outer of radially disposed short roundish-angular ones. Thus there is a more or less broad band of short irregular cells between the long central ones and the cortical fringe of assimilatory filaments. This sub- cortical layer is composed of more or less thick walled cells which, in a transverse section of the frond appear radially elon- — 1 84 — eated or roundish and narrower than the central cells. In a longa- O *^* ttidinal section they are seen to be short and irregular, and they form a distinct broad sheath enclosing the long internal cells in older portion of frond. In younger part the subcortical layer consists of only one or two layers of short irregular cells. The lono- internal cells of the frond are all of much the same dia- o meter, and a transverse section shows them to be much more re- gular than those of Chordaria flagettiformis PL. XC. All the cell-walls of the axile cylindre are thick and show distinct pits, but those of the subcortical layer are somewhat thicker than the central ones. By the decaying of the central elongated cells a large cavity is sometimes produced. The assimilatory filaments are as usual as in the Chordarian plants ; some irregularities are observed in its branching as shown in the fig. 10-11. The frond is firm and tough and a little gelatinous in well grown plant, but in some soft and more gelatinous, especially in younger ones. The firmer fronds do not adhere to paper when dried but softer ones closely. Colour yellowish brown turning to black when dried. Hab. : On rocks between tide marks extending to 1-2 fathoms.

The present plant is most nearly related to Chordaria flagel- liformis Ag. in the substance and external appearence ; but it differs from the latter in being more or less distinctly tubular and possessing a broad Land of subcortical cells. In the latter the longitudinal cells are of irregular size while in the present plant tliey are almost uniform. From Chordaria Cladosiphon Kg. p. 1 66, PI., CXLIV, the present plant may be distinguished by firm and coriaceous substance (in older fronds and older portions of a frond), by alternate mode of branching, by densely compacted strata and by having more or less thick subcortical sheath.

Fronds tufted. 20-40 cm hi^h. * *^ * 0.5-1.5 mm. or more in diameter, filiform when young-, becoming thicker and cylindrical when old. Branches arise laterally on all sides at lower portion of frond, but upward dissolve more deliques- cently and irregularly in dichotomo-alternate manner at longer or shorter intervals, with some scattered lateral segments, either bare of ramuli or with some of them, especially in younger fronds. Branches and branchlets soft and pliable, very widely diffused in various directions and slightly flexuose. The branches and their lesser divisions taper to slender apices and more or less narrowed toward their origin. In older fronds branches become usually naked or bare of ramuli and tapering of their basal portions is more manifest than those in younger frond. The frond is hollow from the beginning and the tube is very wide being more than one-third the diameter. The axile cylinder is formed of rather loosely compacted longitudinal cells with wide calibres having many intercellular spaces. The wall of the longitudinal cells is slightly thickened and shows distinct pits. Along the inner side of the axile cylinder there are a few scattered cylindrical cells with nar- row diameters. From the outer roundish cells of the axile cylin- der assimilatory filaments and hair-tufts arise. The assimilatory filaments consist of 3-4 subcylindrical cells of which the terminal one is obovate or roundish. Zoosporangia are carried at the ba- sal joints of assimilatory filaments, oblong or elliptico-oblong. The substance is soft and membranous, very gelatinous, but the cross- section of dried frond extends with elasticity ; the plant closely adheres to paper in drying. Colour yellow brown, turning to blackish in drying. Had.: On fronds of several plants such as Sargassum, Phyllo- spadix etc, rarely on stone (?), extending from tide marks to 1-2 fathoms. Provs. Awa, Mikawa, Rikuzen, Rikuoku, Noto, Sado and Kitami ; Seishin (Chosen). On referring the plant in question to the present species, I have not been able to see any reliable specimens. But from the illustrations given by Harvey in Phyc. Austr. tab. 60, and the descriptions given by him and J. Agarclh, I think I am justified in doing so. Harvey states that the plant has a percurrent stem, but J. Agardh that it branches deliquescently. Again, Harvey mentions that the axile cylinder is formed of very densely com- pacted and agglutinated longitudinal filaments exactly as in Clwr- daria and J. Agardh that " cellulis exigua distantia juxtapositis ambitu rotundatis, amplioribus et fere duplo tenuioribus sine ordine adparente intermixes." These statesments are somewhat at varians with ours, though in our plants all of the longitudinal cells are not of exactly equal diameter and some have narrow calibres, yet the cross-section of frond shows them to be much more regular than that of C. flagclliformis and to be much loosely packed together. The near allies among our plant is Ch. fir ma PL. CXLIII from which it differs in many points especially in the soft sub- stance, mode of branching, habit of growing on algae instead of on stone and structure of frond. Though by those differences the two plants are easily distinguishable from each other, yet in some cases there are some specimens very difficult to separate one from the other. In different localities and ages the plant much varies in size, diameter and ramification. In some, branches are more al- ternately disposed, in others more dichotomous ; some have loose and barren branches, others densely ramellosed. By such varia- tions some samples show a remarkable external resemblance with Cladosipliou dccipicns PL. LXXXIX. PL. CXLIV.

Contr. to the Knowl. of the Mar. Alg. of Jap. Ill, (Bot. Mag. Tokyo Vol. XIII, 1899, no. 145 p. 37) PL I, f. 12-14. " Fronds filiform, almost cylindrical, about i cm. in length or less, about 217 ,« in diameter, decumbent, adhering to substratum by emitting root-fibres from the lower surface. Root-fibres simple, elongated or remaining short, either ending with a blunt apex or expanding into a radiato-scutate disc, limited to the main branches, which are few and patent. ' Langtriebe ' and ' Kurztriebe ' are arranged in a subdistichous manner, lying on almost but not quite exactly on one and the same plane. While some ' Kurztriebe ' arise from the dorsal side very slightly above the plane of ' Langtriebe,' there are others which stand on the same level with the latter. 'Langtriebe' spread out laterally with non- inrolled apex, and ' Kurztriebe ' almost horizontally, while the latter standing near the growing portion of the shoot are incurved toward the apex of axis. The 'Langtriebe' stand on alternate sides at every fourth articulation, and the ' Kurztriebe ' similarly t arise from articulations devoid of the 'Langtriebe.' A 'Langtrieb always stands directly above a ' Kurztrieb ' on the same side. The latter is short, 500-600 /* long. 80-140 n broad, somewhat cylindrico-oblong, tapering to a bluntish apex trom an equally broad or slightly constricted base, carrying in its young state very short and minute deciduous fibrillae at the apex. Tetraspores are ar- ranged in a straight line in a slightly expanded ' Kurztrieb,' 4 or — 2OO — 5 in number, externally covered by two outer cells of equal length. Frond is ecorticated throughout, furnished in the main branches with 1 1 pericentral tubes surrounding the central axis vhich has a wider calibre, and shows 4-5 tubes in surface view. Articulations about half as long as the diameter. Colour dark brownish red, almost blackish when dry." — Okam. I.e. Hab. : On various algae such as Gelidiwn, Anipliiroa etc. between tidemarks. Prov. Hyuga, Futae (Prov. Higo), Enoshima, Bosyu. Remarks. " Owing to the greater obsculity of the dorso- ventral arrangement of parts than in Herposiphonia fissidentoides Holmes, the present plant does not appear at first glance to be referable to this genus ; but its regular arrangement of ' Langtriebe ' and the formation of fruits in ' Kurztriebe ' tell us its nature. The present plant which is very closely allied to H. fissidentoides differs from the latter in the narrow and non-leafy ' Krrztriebe.k — Okam. I.e. PI. CXLVI, Fig. 11-18.
