Abstract
The writers studied the chromosome numbers in 18 species or varieties of Leguminosae which come into flower mainly from spring to summer in the northern part of Kantô district.
1). The basic numbers of chromosomes observed are 6, 7 and 8. Genera Trifolium and Vicia have two basic numbers of chromosomes, namely in the former 7 and 8, and in the latter 6 and 7, respectively.
2). 80 percent of the material plants was found diploid. Tetraploid species are very few compared with Gramineae.
3). A relationship among polyploidy, distribution and forage value in leguminous plants was scarcely observed.
