Scientists collect rare plant seeds from sinkholes in SW China
The time around the Mid-Autumn Festival is the best season for collecting seeds.
Three months ago in the sinkholes in Mengzi City, southwest China's Yunnan Province, researchers from the Kunming Institute of Botany found two rare plant species, Petrocosmea grandiflora and Elaeagnus bambusetorum, which have been out of people's sight for more than 100 years.
At that time, they only collected specimens of the flowers and leaves, but now they're heading back to collect the seeds.
