Spermatophyte flora of Dafang Fokienia hodginsii National Reserve

Based on specimen collection and identification, and referring related literatures, this paper studied the composition of spermatophyte flora and its geographic elements in Dafang Fokienia hodginsii National Reserve. The results showed that the spermatophyte flora in the reserve belonged to the Central China region, and was the core of Sino-Japan forest flora. There were 132 families, 476 genera and 1 060 species of wild spermatophyte. The basic features of the flora were abundant in species and complex in geographical elements, with a relatively higher connection on family level by 61.11% and a relatively higher connection on genus level by 55.61%. The origin of the flora was very ancient, with many monotypic genera and oligotypic genera, and of typical calcicoles.
