Domestic specimens from Guangdong Province and foreign specimens from USA have the largest percentages representatively. There are 6351 type specimens belonging to 4373 species in 938 genera, 194 families. These data provide information for locating biological diversity hotspots, and for making plans for collection work in the future.
