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

1.Nishida，M.和H.Nishida于1045年和1046年采集了Saghalien上白垩统的渗碳木，描述了7个种，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)。他们还检查了来自田地、岩手县、北海道和萨加林的云杉属木材，确认了6个种，其中包括3个新种(见关于结果和组的单独报告。Nishida，H.描述了岩手县田内市的一新种。这一发现是这种神秘蕨类化石在亚洲和日本的首次记录。(Nishida，H.，1986)他还研究了Gleicheniaceae的叶柄、Matoniaceae和Dennstaetdiaceae的根茎以及Anymaceae的可育小羽片，并在1987年7月于柏林举行的植物学大会模拟研讨会上作了关于它们的演讲。

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.
