Abstract
IN an experimental study of cell and nuclear division, especially in Vicia faba, Sakamura (Journ. Coll. Sci., imp. Univ. Tokyo, vol. xxxix., article 11) has made an important contribution, particularly witn regard to the lactors that may inliuence the form, size, and number of the chromosomes. He finds, in agreement with most previous investigators, that V. faba has twelve chromosomes, the earner counts of fourteen being due to a constriction which appears constantly at a certain point on the longest pair of chromosomes. Two other species of Vicia have fourteen chromosomes, three have twelve, while V. unjuga is tetraploid, having twenty-four.
