Some representative conifers ar:e discussed in this and the following article from the viewpoint of taxonomy and phytogeography. In this paper, short phytogeographical notes on all eight coniferous families are given, five of which have subalpine species. Then, the distribution patterns of the genus Larix and Tsuga were examined with reference of distribution maps. In both genera, the distribution of the primitive groups, Larix sect. Multiseriales and Tsuga sect. Heopeuce or sect. Hesperopeuce, is restricted in East Asia and the Pacific side of North America; while whereas, the distribution of the advanced species, e.g. Larzx sibirica and Tsuga laricina, is more extensive.
