Adoxa moschatellina is revised from the standpoint of floral morphology and anatomy. A new interpretation is given for the flower of Adoxa, considering the systematic position of it. The ancestral form of the lateral flower is suggested here to be 3-merous. The flower having three calyx-lobes and five corolla-lobes seems to have been derived from typically 3-merous flower by the reduction of a pair of posterior stamens and the fusion of two posterior corolla-lobes. The lateral flower is regarded as 3-merous, and the terminal one as 2-merous. The flower of Adoxa shows peculiar floral diagram, where are two corolla-lobes between the calyx-lobes. The relationship between Adoxa and Sambucus, Chrysosplenium, or Panax is discussed briefly in relation to the above speculation.

1. Seven species of Rabdosia were compared by the cultivation on the soil of various degrees of moisture. The growth was measured by the shoot length, the number of the nodes of stem, and the size of leaves for each cultivation on 53-55 days after the germination. 2. The results are summarized in Figs. 1 and 2. For every species except R. japonica, response was similar in appearance. The optimum soil moisture was 60% and 80% of maximum water capacity. When cultivated with 40% and 100% water supply, the growth was distinctly reduced, and on the media with 20% of water supply the plants became stunted or often died. In R. japonica, the range of optimum soil moisture was very broad and 40% to 80%. On the media with 20% and 100% water supply the growth was similarly bad. 3. Compared with the vicarious varieties restricted to the Pacific Ocean side, those of Japan Sea elements, R. shikokiana var. occidentalis and R. umbrosa var. hakusanensis, showed a tendency to have maximum growth on the media somewhat higher in soil moisture (80%).

The inner structure of cinnamon barks of 4 species (Cinnamomum burmanni BL., C. cassia PRESL, C. zeylanicum BL. and C. iners REINW. ex BL.) is described each at 3 different levels. These 4 species are distinguished by the inner structure of their barks. There are two types in C. burmanni: one has interrupted stone cell ring, many big stone cell groups and few bast fibers, the other has circular stone cell ring, few small stone cell groups, many bast fibers and lignified thick walled parenchyma cell or tissue. Crystals are the same, cubic or prismatic and sandy. These characters are assumed to correspond to the varieties of the same species. C. zeylanicum and C. iners are quite similar, and their common characters are circular stone cell ring, many bast fibers and rhombic or spindle and sandy crystals. The differences are : C. zeylanicum has stone cell groups in phloem and few amounts of lignified thick walled parenchyma cells in U-form in cortex, and C. iners has scarcely stone cell groups but many of U-form cells. C. cassia differs from the other species; it has circular or fluted stone cell ring, few bast fibers, many and big oil cells in phloem and needles and sandy crystals.

Frond articulation in species of Loxogramme was observed anatomically in details. Abscission layer composed of several layered obtuse parenchyma cells is clearly distinguished between phyllopodium and stipe in mature fronds of L. salicifolia and L. saziran. The disarticulation occurs at this separation layer. Leaf scars protruding from rhizome which do not become lignified but tanniferous at the upper concave surface are formed after disarticulation. The abscission layer is formed already at youngest stage of the development of a frond. This abscission is the same structure as in some species of the Polypodiaceae. Thus, the frond of these two species is safely regarded to have articulation to the rhizome. Clear leaf scars are also observed in such species as L. avenia, L. formosana, L. involuta, L. parksii, and L. remotifrondigera. These species seem to have the same frond articulation type as L. salicifolia and L. saziran. The abscission layer is observed neither in L. grammitoides nor in L. lankokiensis. L. grammitoides has phyllopodium with scales on its surface and the shape of the cells is the same as that of L. saziran. The abscission is scarecely observed in small frond of L. salicifolia and Microsorium hancockii just like as in L. grammitoides. From the facts noted above, the lack of the abscission of the two species belonging to Loxogramme seems to relate the fact that these species have small frond with slender stipe.
