    The available data from the present study concerning the development to the tannin vacuole in the pulvinus of Mimosa pudica may be summarized as follows.
    1. By fixing the motor tissues with Kaiser's solution the tannin vacuole formation of all stages was demonstrated. The protoplast of young cell, which contains vacuole at first, begins to have a tiny original body of tannin nature at a certain stage.
    2. The presence of the tannin vacuoles is by no means relevant to the sensitivity of the motor cell in young seedling.
    3. As the result of the material confusion in motor cell, which may be caused by the bending movement, the morphological change in the tannin vacuole appears in the motor cell.
    4. In the young pulvinus of Robinia pseudo-Acacia, tannin substance appears in the central vacuole of the parenchymatous motor cell, forming a vacuolar appearance. In the full grown pulvinus, the tannin vacuole finally fills up the whole central vacuole of the cell, leaving no trace of the latter.

    全陽光乾燥, 同湿潤, 庇陰乾燥ならびに同湿潤の4区をガラス室内に設置し(庇陰区は関係光度13%, 土壌水分は湿潤区が容水量の85%, 乾燥区が25%とした), シラカシの3年生苗をこれらの試験区で栽培した。これらの処理をおこなつて約14ケ月後に当年生葉の補整点, クロロフイル含量, 全窒素含量, 無機要素含量などをしらべてつぎの結果を得た。
    1) シラカシの補整点は光度だけでなく, 土壌水分の影響をうけて庇陰下で低くなる。光度の影響は乾燥区にとくに著しい。同じ光度では湿潤区の補整点が低い。
    2)葉のクロロフィル含量は庇陰下に高く, 土壌水分の影響は本実験の範囲内では認められない
    3)葉の全窒素やK2Oの含量は庇陰下に高く, 灰分, SiO2, P2O5は全陽光下の葉に多く含まれている。湿潤区の葉には全窒素, SiO2, K2Oが多いが, 乾燥区ではCaO, MgOが多い。低光度での光合成能力は庇陰によつて高まり, 水分によつて塩類のバランスが保たれるが, 庇陰下では生命活動が衰えているようである

    1)The chromosome numbers and the karyotypes of genus Philonotis and genus
    Bartramia studied are as follows;
    Philonotis falcata (Hook.) Mitt _??_K(n)=6=V(X)+3V+J+m(h) _??_K(n)=6=V(Y)+3V+J+m(h)
    P. japonica (Schimp.) Par. _??_K(n)=6=V(X)+3V+J+m(h) __??_K(n)=6=V(Y)+3V+J+m(h)
    P. carinata Mitt. _??_K(n)=6=V(X)+3V+J+m(h) _??_K(n)=6=V(Y)+3V+J+m(h)
    P. lancifol Mitt. _??_K(n)=6=V(H)+3V+J+m(h)
    P. seriata Mitt. K(n)=6=V(H)+3V+J+m(h)
    P. Turncriana (Schwag, ) Mitt. _??_K(n)=6=V(H)+3V+J+m(h)
    P. socia Mitt. (monoploid) _??_K(n)=6=V(X)+3V+J+m(h) _??_K(n)=6=V(Y)+3V+J+m(h)
    P. socia Mitt. (diploid) _??_K(n)=12=2V(X, Y)+6V+2J+2m(h)
    Bartramia pomiformis (L) Hedw. _??_K(n)=8=V(H)+3V+2J+m+m(h)
    B. crispata Shimp. _??_K(n)=8=V(H)+3V+2J+m+m(h)
    2)The sex-chromosomes have been found in the four species of Philonotis X and Y are the largest V-shaped heterochromosomes of the male and the female chromosome complements respectively.
    3) The intraspecific polyploidy has been found in Philonotis socia (n=6, 12). The diploid plant is a monoecious having two sets of chromosome complements, each of which is similar in the morphology of the formative elements to that of the male or female gametophyte of a monoploid plant respectively. These evidences are suggestive that the diploid plant may have stemmed from the monoploid one by sporophytic apospory.

    1. This report concerns with the results of the author's observation on the characteristics and the types of pairing of chromosomes in the reduction division of P.M. Cs. in the F1. hybrid (2n=14) which was produced by crossing R. trifidus Thunb. (2n=14) ×R. ribisoidesMatsum. (2n=14).
    2. In this hybrid, the characteristics of R. trifidusare found in the cyme, the glandular hair, the wrinkles of petals and the color of stems (red-purple), while the characteristic of R. ribisoides in the wool on leaves and stems. On the other hand, with regard to some characteristics, e. g. the size of flowers, the shapes of leaves, the serrate and stipule, this hybrid is intermediate of its both parent plants.
    3. The peduncle of this hybrid, stands, at first. upright like that of R. trifidus, and then it turns downwards like that of R. ribisoides. This is a case of dominance change.
    4. The types and frequency of pairing of the chromosomes in the metaphase of the first reduction division of P.M. Cs. in this hybrid are as follows: 7II (35.5%), 6II+2I (40.9%), 5II+4I (18.3%), 4II+6I (4.3%) and 3II+8I (1.1%).
    5. There are two kinds of pollens in this hybrid; the pollens having contents and the empty pollens. The ratio of their occurrence being 45:55.
