東洋英和女学院大学キャンパスに生育する植物の注釈つきインベントリー : 食用植物

In this paper, the result of an inventory of plants fit for human consumption found on the campus of Toyo Eiwa University is presented, and how these plants can be used is described. Each description includes the Japanese plant name, its Latin name, the name of the part(s) of the plant used, and the literary source of each plant\u27s use with an annotation. Among the plants on the Toyo Eiwa University campus, 276 such species have been found. These plants therefore are useful in promoting learning through nature and in the enrichment of life. Some notes of importance, for example, to know how to identify such plants, the history of such plants, plants as these used in children\u27s games, the cooking and preservation of these items, their local names, the manner of plant collection, and a list of poisonous plants are also included. A plan for utilizing this information to develop learning programs for students and people of the surrounding communities is also described

東洋英和女学院大学キャンパス内に生育する植物の注釈つきインベントリー : 遊びに使用される植物

In this paper, the result of an inventory of plants (which are used in children\u27s play) found on campus of Toyo Eiwa University is presented and how these plants are used is described. Each description includes the Japanese plant name, Latin name, name of children\u27s play or game where it is used, the name of the part(s) of the plant used in that particular game or play, and the literary source of this plant\u27s use in this way. Among the plants on the Toyo Eiwa University campus, 206 different species were found and these can be used in 588 types of children\u27s play or games. These plants therefore are useful in promoting learning through nature and the enrichment of life. A plan for utilizing this information to develop learning programs for students and people of the surrounding communities is also described

Extreme Multiple Reticulate Origins of the Pteris cadieri Complex (Pteridaceae)

The Pteris cadieri complex displays extensive morphological variation and seems to have originated through hybridization. However, the members of this complex reproduce by apogamy, which usually limits genetic variation. To evaluate the hypotheses of hybrid origins, the pattern of evolution in this species complex is reconstructed. Multiple methodologies were used. Diploids, triploids, and tetraploids were identified by chromosome counts and flow cytometry. Nuclear DNA markers (cytosolic phosphoglucose isomerase gene, PgiC) were used, together with chloroplast DNA markers (atpB-rbcL spacer and rbcL gene) to infer the biparental and maternal lineages of the Pteris cadieri complex. The three cpDNA haplotype groups and five PgiC alleles found in this study indicate that the evolution of the Pteris cadieri complex has been extremely reticulate. Up to 11 taxa belonging to eight morphs were identified. By comparing genetic variation in the Pteris cadieri in two independent areas, Hainan and Taiwan, we inferred that hybridization has occurred independently in different areas. Furthermore, we found evidence for phenological divergence (evergreen and deciduous) within Taiwan. We propose that the Pteris cadieri complex originated from different genetic lineages through multiple hybridizations in different geographical areas, leading to its present morphological diversity
