迄今为止，在日本白垩纪植物群中还没有发现荷叶，尽管在九州、北海道和saghalian（新近纪基底）的一些煤矿的l' aleocene地层中已经发现了荷叶。远藤教授（1931）以Nelumbo nipponica的名字描述了这些。1)该物种已被Dr. II.报道。YAIIII（1944）产自多摩宇部煤田。同时，Ncluntbo sp.的发生已由Prof. 1报道。TATEI VA（1934）来自韩国a3)材料由S. SIIIMAMURA在韩国南部北真罗道中国地区的白木系列（上白垩统矿床）最上层收集。但其古生物学描述至今尚未发表。因此，据作者所知，这一新的阿苏瓦植物是东亚最古老的荷叶遗迹。然而，根据ENoo的论文，在东亚以外的地区，在阿拉斯加半岛、北美和法国南部的白垩纪晚期植物群中也发现了荷叶。5) HEER曾经认为Nelumbo属起源于白垩纪晚期的北极地区。那么，至少在北极地区，Nelunthe化石物种的出现可能被证明对上白垩纪地层的对比是有用的。日本国内普遍认为，我国近代的荷花（Nelumbo nucifera GAERTIN）是古代从中国传入的
Lotus-leaves have not hitherto been discovered in the Cretaceous Flora of Japan, although they have been known from the l'alaeogene formations of some coal-mines in Kyusyu, Hokkaido and Saghalien (the basal part of Neogene). These have been described by Prof. S. ENDO (1931) by the name of Nelumbo nipponica.1) And this species has been reported by Dr. II. YAIIII (1944) from the Ube coal-field, Tama. guchi Prefecture2) Meanwhile, the occurrence of Ncluntbo sp. has been reported by Prof. 1. TATEI VA (1934) from Korea3) The material was collected by S. SIIIMAMURA from the uppermost part of the Shiragi Series (Upper Cretaceous deposits) at the Chinan district, North-Zenra-Do, southern Korea. However its paleontological description has not been published until now. Therefore, this new species of Asuwa Flora is the oldest remains of the lotusleaf in eastern Asia, as far as is known to the writer. Outside eastern Asia, however, lotus-leaves are known to occur in the upper Cretaceous floras of Alaska Peninsula, North America and southern France4) According to ENoo's paper.5) HEER once thought that the genus Nelumbo originated somewhere in the Arctic region during the upper Cretaceous time. Then, the occurrences of fossil species of Nelunthe may prove to be useful for the correlation of the upper Cretaceous formations at least in the Arctic Region. It is generally considered in Japan that the recent lotus (Nelumbo nucifera GAERTIN) of our country was imported from China in an ancient time, while
