イヌガヤの雄性配偶子について

抄録

In Cephalotaxus drupacea Siebold et Zuccarini, by a division of a boby cell, two male gametes are formed. They are two cells of unequal size. The nuclei of these two cells are about the same in their appearance, but the one of the small cell is slightly smaller than the other. The gametes have no membrane on their surface. These results does not agree with Lawson′s report on the same species.
