Abstract


Recently two thousand year old several villages ruins were discovered at Amsadong, Daeshimli and Hunbaukol near the Han River side in Korea.
An investigation of the present flora of these three localities was done. There are 84 families including 419 species of vascular plants. The vegetations of flora in the localities of the Han River side are very similar. The forests are poorly developed and appear as the secondary vegetations. The reforest plants can be recognized as Pinus rigida, Quercus acutissima, Q. serrate, Robinia pseudoacacia and Ainus hirta.
Herbaceous plants of Miscanthus sacchariflorus and Phragmitis japonicus bind up the soiles of the Han River side. Populus nigra grows abundantly in the moist places of sand bars which are located on the river side south of Daeshimli and on the northern side of the Han River across from Hunbaukol.
These three area are fully cultivated but still many primitive farm techniques are employed. Farm produce crops include rice, corn, barley wheat, other vegetables, and a few ornamental plants.
In this study the author found flower color variations ranging from a dark blue to a pale blue, and chromosome number differences existing between the populations of Commelina communis. The dark blue flowered taxa chromosome number is 44 and in the pale blue taxa it is 72.
The wild white flowered Chrysanthemum is Chrysanthemum zawadskii Herb. ssp. acutilobum and which has finely lobed leaves, and has 54 chromosome in the root tip cells.
