The following results concerning the phylogeny of Angiosperms, Particularly relating extinct gymnosperms of preangiosperm stages have been obtained.1. A gymnospermous female fructification, which is supposed to be a new order, from the Cretaceous of Hokkaido will soon be published elsewhere in a scientific journal. This fructification develops a thick envelop around a large unitegmic seed, and is morphologically comparable, but analogous to the angiosperm fruit.2. A bisporangiate reproductive organ from the Cretaceous of Hokkaido was assigned to a flower of a bennettitalean plant, Cycadeoidella Ogura (1930). The bennetitalean flower has never been described from East Asia before this finding. This well-preserved organ provides important and unequivocal evidence for better understanding the reproductive biology of the bennettitaleans.

本文对被子植物的系统发育，特别是前被子植物阶段的已灭绝裸子植物的系统发育进行了研究，取得了如下结果：1.北海道白垩纪的裸子植物雌性果实，被认为是一个新的目，不久将发表在其他科学杂志上。这种果实在一个大的单珠被种子周围形成一个厚的被膜，在形态上与被子植物的果实相似。北海道白垩纪的一个双孢子囊生殖器官被指定为一种本内苏铁目植物的花，Cycadeoidella Ogura（1930）。在这一发现之前，从未在东亚描述过本内特塔利亚花。这个保存完好的器官为更好地了解bennettitaleans的生殖生物学提供了重要而明确的证据。
