Chromosome numbers of five species and two varieties of Japanese Corydalis were determined. The results are summerized in Table 2. There are two cytological races in C. capillipes. I wish to express my thanks to Prof. Dr. Sadao Sugaya of Tohoku University for his advice and criticism throughout this study.

Mature spores of Loxogramme are observed in details. Some species of this genus have bilateral spores, and the others tetrahedral ones, though none of the species has both types of spores. This is certified also for Vittaria and Lindsaea. Tetrad formation is observed on the spores of some species of Loxogramme, comparing with that of the typical form of the type of tetrahedral tetrad; the granule zone which is observed at equatorial plane of heterotypic nuclear division is dissolved during homeotypic nuclear division. This type of tetrad formation is also observed at heterotypic nuclear division of L. saziran and L. salicifolia is not dissolved until the cell division occurs and bilateral tetrad is made. This type is observed in Microsorium hancockii and Dryopteris lacera. From the observations noted above, the spore character does not support positively to place Loxogramme in the Grammitidaceae.

The migration of the people in the ancient time can be guessed especially from the comparison of the vernacular names of the food plants of each people. In this report, the writer cited Cicer arietinum and Tacca pinnatifida as the examples.
