A check list of flora and endangered species of lucidophyllous forest was made according to red data books and others, in order to clear characteristics of the flora and critical conditions of the endangered species of lucidophyllous forest at Kyushu and northward in Japan. The number of component species of lucidophyllous forest in each prefecture had a high positive correlation with low temperature during winter. The life form compositions of lucidophyllous elements were studied. The life form of the lucidophyllous elements was classified into 19 categories. The value of lucidophyllous tree was about 24 per cent. The dominant life form categories were forest floor herb and epiphytes. Species richness of lucidophyllous forest depended on many ferns and orchids in forest floor herb and epiphytes. About 30 per cent of the total number of component species of lucidophyllous elements is endangered. The endangered species were, for the most part, ferns and orchids.
