    A brief general discussion of the general meaning of transpiring power is followed by a detailed account of the present status of the method of CoCl2 paper for estimating foliar transpiring power. Full directions are given for preparing both standard hygrometric paper and the four standard color papers that are employed in the timing of the color changes that indicate rates of water-vapor absorption by the hygrometric slips. A standard water-surface apparatus is described; also a tripartite slip, which consists of a hygrometric slip and two color-standard slips combined. Procedures of computation are also presented, by means of which results secured with this method may be interpreted. Finally, Some examples are given from experiments, to illustrate applications of the method.

    Ich habe aus einem Fall von trichophytieähnlichem Hautleiden, welches ein japanischer Diplomat während des Aufenthaltes in Äthiopien bekommen hat, eine neue Art von Cephalosporium als Erreger rein kultiviert und tierexperimentell seine Pathogenität sicher nachgewiesen. Ich habe diese Spezies mit den bisher beschriebenen Cephalosporium-Arten verglichen und keine Identität mit den anderen Cephalosporium-Arten finden können. Aus diesem Grunde möchte ich diese Spezies als neue Art “Cephalosporium nigrum KAMBAYASHI nov. sp.” benennen.

    1. Najas has a highly simplified flower due to adaptation to aquatic life but its phylogenetic origin may be drawn from submerged Hydro-charitaceae.
    2. The original home of Najas may be regarded as Africa, where many primitive species and many allied genera exist, both of which show a concentric distribution from Africa.
    3. The flower of Potamogeton may be considered as a reduced inflorescence viz. a central female flower surrounded by 4 staminate flowers, as in the flower of Cyclanthaceae.
    4. The descent of Potamogeton from Helobiae is not probable and it is rather reasonable to conceive that the genus was derived from Pandanales or Synanthae.
    5. The phylogeny of the group may therefore be drawn as the following diagram:

    Bei Cephalotaxus drupacea S. et Z. wurde die Nebenreihe 2, 5, 7, 12 ... gefunden und die Divergenz statistisch gemessen. Sie folgt nicht dem Wert der SCHIMPER-BRAUNSchen Divergenz, sondern dem Limitwert 151°8′8″.
    Die Divergenz α und der Quotient β/α, worin β den Restwinkel darstellt, stehen im engeren Zusammenhang mit der göttlichen Proportion χ.
    Bei den ersten Reihensystemen wie 1, a, 1+a, 1+2a ……, die im Pflanzenreich am häufigsten vorkommen, verhält sich der Quotient β/α und die Divergenz α mit χ wie folgt: β/α=χ, α=1/a+χ.360° (a_??_1) und je kleiner a ist, desto häufiger tritt die Reihe auf. Deshalb kommt die Hauptreihe, in der a=1 oder 2 ist, am häufigsten vor.
    Bei den zweiten Reihensystem wie p, ap+1, (a+1)p+1 …… verhalten halten sich β/α=1/a+χ und α=1/p+1/a+χ.360° (p_??_2, a_??_2) und unter diesen sind die Reihen 2, 5, 7 ……, 2, 7, 9 ……, 2, 9, 11 …… bekannt.

    I. Die Typen der aitiogenen Induktion der Dorsiventralität von Assimilationsorganen kann man wie folgt zusammenfassen. Soweit bisher bekannt wurde, findet man den in Klammern eingeschlossenen Typus nicht unter den höheren Pflanzen.
    1) photogen
    A labil:
    a) Die Wurzel von Taeniophyllum, Phalaenopsis und anderen epiphytischen Orchideen.
    b) Das Cladodium von Phyllocactus grandis.
    c) Das unifaziale Blatt von Podocarpus imbricata und “Blattpolster” von Thujopsis dolabrata, Thuja japonica, Chamaecyparis obtusa und anderen Cupressineen.
    (B stabil: Die Brutkörper von Marchantia und anderen Lebermoosen.)
    2) geogen
    A labil: Das unifaziale Blatt von Iris japonica und Iris formosana.
    B stabil: Das unifaziale Blatt von Iris uniflora und Iris Rossii.
    II. Alle Organe, bei denen die aitiogene Dorsiventralität beobachtet wurde, sind phylogenetisch junge Organe.
    III. Die Empfindlichkeit bzw. die Reaktionsfähigkeit den äusseren Faktoren gegenüber ist verschiedenen bei einzelnen Gliedern ein und derselben Pflanzen. Sie steigert sich mit zunehmender Ordnung der Sprosse bei Cupressineen und Phyllocactus grandis. Bei dem Keimlinge von Iris formosana zeigt das siebente oder achte Blatt erst die Folgestruktur. Die Keimachse von Iris uniflora und Iris Rossii schliesst mit einer Infloreszenz ab, ohne dorsiventrale Blätter zu entwickeln, während die Seitensprosse stabile, geogene Induktion aufweisen.

    Reaction times of many leaves of Aldrovanda are measured at various temperatures, using cinematography. When the stimulus is not strong, the frequency distribution diagrams of reaction times are skewed extremely to the left, every diagram showing two conspicuous modes at its left side (Figs. 2 and 3). The positions of the modes are affected by temperature in accordance with the BELEHRÁDEK formula. When the stimulus is strong, almost all the leaves show reaction times which correspond to the first mode of the case of the weak stimulation (Table 2). Possible causes are suggested.

    1) The mature pollen grains of eighteen angiospermous species were investigated in the living and the fixed state, with special references to FEULIGEN'S nucleal-reaction.
    2) The “droplets-sheath” has been found around the generative nucleus in nine angiospermous species (Monocotytedonae: six species; Dicotyledonae: three species), while it could not be observed in nine species.
    3) The quantity of the thymus nucleic acid contained in the vegetative nucleus is of various degrees in the different species, and does not correlate with the degree of transformation of the vegetative nucleus.

    1. In the genus Magnolia there is a polyploid series from diploid to hexaploid, the triploid being yet unknown, and the basic number of chromosomes being 19.
    2. M. purpurascens is a pentaploid plant, but not tetraploid as in the case with M. Soulangeana which is an artificially raised interspecific hybrid between M. denudata and M. liliflora. The sporophyte chromosome number (95) in M. purpurascens is the sum of the gametophyte number of the supposed parent plants, our denudata (57) and liliflora (38). These faets support MAKINO'S view based on the external morphological characters of the plants.
    3. Existence of a tetraploid M. denudata in nature is suggested.
    4. The “furrowing” is not the primary cause of the cytokinesis as was maintained by FARR, but follows the MLI formation.

    Late G. NAKAGOMI and I reformed the method of spodogram inventing a nickel apparatus, instead of WERNER'S or OHARA and KONDO'S aluminium apparatus.
    This study was carried out by the reformed method. Hardly any study of spodogram has been made on the leaves of borraginaceous plants, except one species, Plumonaria officinalis L., spodogram of which is inspected in Y. KONDO: Blatt-Aschenbilder wichtiger Krautdrogen' Journ. Pharmac. Soc. Jap. No. 615 (1933).
    The leaves of the plants of this family are more or less hairy. Outer membrane of the hairs and some surrounding epidermal cells of them are silicated. The spodograms of these leaves are quite characteristic to those silicated parts together with other inorganic cell contents.
    I am quite interested in it, and intend to study the relation between the spodogram of the leaves and the system of the family.

    1. From 3 species of brown algae, Fucus evanescens, Eisenia bicyclis and Laminaria angustata, a mucilaginous substance forming the content of the mucilage-passage, was prepared and its chemical properties were examined.
    2. On the basis of findings that the mucilage of Fucus is acid in nature and that both of its components, fucose and sulphate, exist approximately in an equimolecular ratio, the substance is considered as a polymer of the acid fucose monosulphate.
    The mucilage of Eisenia seems to be more complex in nature. Upon hydrolysis it yielded in addition to free sulphate and fucose a considerable amount of glucose. Although scarcely decisive, the analytical data, that the molecular ratio of fucose to organic sulphate is nearly 1:1, makes the supposition probable, that the sulphuric acid is bound to fucose as an acid monosulphate.
    The mucilage of Laminaria, which differs from those of Fucus and Eisenia in being highly resistant to acid hydrolysis, gives rise to free sulphate and sugars on hydrolysis, whereby, however, neither fucose nor glucose could be as yet detected.
    3. As far as the above observations go, it may be concluded with certainty, that the mucilaginous substances obtainable from different species of brown algae are not of the same chemical nature. The bearing of these substances on the mucilage of higher plants is discussed.

    Root tips of 5 pot-plants of Crepis capillaris were fixed at intervals of one hour during a day. Number of the dividing nuclei (excluding those of the late telophase, interphase and early prophase) at each time was counted. The stages in which the dividing nuclei were counted were classified into 6, namely, 1) late diakinesis and early mataphase, 2) metaphase, 3) late metaphase and early anaphase, 4) anaphase, 5) late anaphase and 6) early telophase. The results obtained are shown in Table 1. Two marked dividing periods and consequently two resting periods were observed as seen in Fig. 1. It is interesting to note that at the beginning of the dividing periods nuclei of the earlier stages are great in number, and at the end of the same periods many nuclei of later stages are observed (Figs. 2 and 3).

    Here I treated Sadogasima, Awasima, and Tobisima as the islands of the northern Japan Sea, having 880sq. km., 9.3sq. km. and 2.3 sq. km. respectively. Although very small they are, except the island Sado, these islands occupy important situation on the distribution of the marine algae. They are extended from 37°48′15″ to 39°12′18″ of the north latitude. These islands are quite warm for their northerly situation, their average temperature being 13.2°C., 13.3°C., and 12.5°C. respectively in 1935, owing to the Tusima-current, running closely along them, although branches of the LIMAN-current and Tisima-current give some contrary effect.
    Up to the present time the reports on the marine flora of these islands are very poor, and so far our knowledge concerning the marine flora is obtained to some extent from the works of Dr. K. OKAMURA, Dr. K. YENDO, and Mr. M. NAKAMURA. In general the study of the marine algae in the northern Japan Sea, both in these islands and along the coast of Honsyu, is still in an initial stage. I have studied these several years on the distribution of the marine algae of the northern Japan Sea. With this object I visited Sadogasima (Island Sado) in July 1933, Awasima in Aug. 1935 and July 1936, and Tobisima in July 1931, June 1936 and July 1936. The reports on the distribution of the marine algae in Awasima and Tobisima respectively have been published elsewhere by the author recently.
    1. The species here enumerated are 157 in number, of which 18 belong to Chlorophyceae, 53 to Phaeophyceae and 86 to Rhodophyceae. Among them, 19 species are left for future study on determining the species names, and also *-marked species have not yet been collected by the author, but they are abstracted from several literatures.
    2. From the point of view of algal distribution, in general, almost 75% of the species enumerated here are of the warmer sea, 6% of colder, 7% cosmopolitan, the remainder being unknown.
    3. The species which are endemic in Japan proper are 81 in number., those common to Australia, Malay Archipelago and Polynesia are 30, those common to North America (Pacific coast) 18, and those common to all Europe 24, 8 being cosmopolitan almost all over the world.
    4. Among them the following 10 species are peculiar to the Japan Sea: Ecklonia stolonifera, Cystophyllum caespitosum, Sargassum confusum, S. Turneri, Coccophora Lansdorfii, Grateloupia divaricata, Nemastoma Nakamurae, Chondrus affinis, Crouania divaricata, Laurencia nipponica.
    5. The 20 species numbered 13, 18, 22, 35, 44, 46, 47, 60, 82, 86, 104, 106, 109, 110, 124, 125, 129, 139, 152, 156 in the accompanying table may be regarded as the typical southern elements, while the 8 species numbered 8, 37, 40, 43, 49, 120, 121, 142 can be regarded as the northern elements.
    6. From the point of view of geographical distribution, so far 11 warmer species are recognized as having Sadogasima as their northern limits, while 8 species Awasima and 14 others Tobisima as their northern limits.
    7. Some of the species which have hitherto been treated as produced only in the Pacific coast were discovered on the coast of Japan Sea, such as: Dictyota spinulosa, Heterochordaria abietina, Sargassum Horneri (TURN.) C. AG. f. furcatodentatum, Myelophycus caespitosus, Nemalion pulvinatum, Lithothamnion laeve FOSL. f. tenuis, Jania adhaerens, Polyopes Polyideoides, Hypnea musciformis, Polysiphonia Stimpsoni, Laurencia obtusa LAM. var. majuscula.

    Four F2 plants were obtained from open pollination of the highly sterile wheat hybrid, Triticum persicum var. stramineum×T. Timopheevi. One of them was fertile.
    In the next generation of this individual, yellow and albino seedlings were found beside normal green ones (Fig. 1).
    From the genic analysis up to F5 generation, the author has proved the existence of one gene for yellow (y) and two duplicate albino genes (a1 and a2). These genes are independently inherited.
    The genic scheme for chlorophyll character may be expressed as follows:
    A1A2Y, A1a2Y, a1A2Y ……green,
    A1A2y, A1a2y, a1A2y ……yellow,
    a1a2Y, a1a2y ……albino.
    The heterozygote, A1a1A2a2Yy will thus give 45 green: 15 yellow: 4 albino. However the ratio of the 3 different phenotypes obtained from the heterozygote, A1a1a2a2Yy, is 9 green: 3 yellow: 4 albino (Tab. 1).
    The chlorophyll defective seedlings grew normally a few days; then they died, having probably exhausted the food supply in the endosperm.
