Guangdong Province. The area is 2 189.2 hm2
and the forest coverage rate is 99.47%. In this survey, there are
1 130 species of wild vascular plants in 186 families and 609 genera. Among them, there are 80 species of
pteridophytes belonging to 29 families and 45 genera, 6 species of gymnosperms belonging to 4 families and
4 genera, 1 044 species of angiosperms belonging to 153 families and 560 genera. The tropical components
of pteridophytes are 33 genera, accounting for 91.67% of the non-world genera in the region, and tropical
composition holds an absolute advantage. The tropical components of seed plants are 422 genera, accounting for
79.47% of the non-world distribution genera in the reserve, and tropical composition holds an absolute advantage.
One new record family Hippocrateaceae, 41 new record genera and 215 new record species were found. There are
