Studies on the permineralized plants from the Cretaceous of Northern Japan and Saghalien.

1. Nishida， M.和H. Nishida对已故的Y. Ogura博士和S. Watari博士于1945年和1946年收集的Saghalien上白垩纪的松木进行了研究，并描述了7个物种，其中包括4个新种（Nishida， M.和H. Nishida, 1986； Nishida和M. Nishida, 1986；见本报告第11节）。他们还研究了来自种市、岩手县、北海道和Saghalien的松类木材，发现了6种，其中包括3种新种（见关于结果的单独报告和本报告第11节）2。Nishida， H.描述了岩手县Taneichi的一新种。这一发现是这种神秘的蕨类化石在亚洲和日本的首次记录。（Nishida， H., 1986） 1987年7月，在柏林召开的植物学大会专题会议上，他还研究了一种Gleicheniaceae的叶柄、一种Matoniaceae和Dennstaetdiaceae的根状茎和一种Anemiaceae的可育小叶。

1. Nishida, M. and H. Nishida examined pertified woods from the Upper Cretaceous of Saghalien, which were collected by the late Dr. Y. Ogura and Dr. S. Watari in 1045 and 46, and described 7 species including 4 new species (Nishida, M and H. Nishida, 1986; Nishida and M. Nishida, 1986; see Sect. 11 in this report). They also examined piceoid woods from Taneichi, Iwate Pref., Hokkaido and Saghalien and recognized 6 species including3 new species (see separate report on the results and sect. 11 of this report)2. Nishida, H. described a new species of Tempskya from Taneichi, Iwate Prefecture. This finding is the first record of this mysterious fern fossil in Aisia as well as in Japan. (Nishida, H., 1986) He also examined a petiole of the Gleicheniaceae, rhizomes of the Matoniaceae and Dennstaetdiaceae and fertile pinnules of the Anemiaceae and gave a lecture on them in the simposium of the Botanical Congress held at Jul., 1987 in Berlin.
