Delayed Self-Pollination as the Primary Reproductive Strategy in <i>Cypripedium shanxiense</i> S. C. Chen: Observations From Beijing Songshan National Nature Reserve.

ABSTRACT: Studying the pollination biological characteristics of the rare and endangered plant Cypripedium shanxiense S. C. Chen will provide a scientific basis for formulating conservation strategies for the species. This study investigates the flowering phenology, pollination insects, and the process of pollination and fruiting of C. shanxiense at the Beijing Songshan National Nature Reserve. The results indicate that the flowering period of C. shanxiense is 12-16 days. The full bloom period extends from early June to late June, with the population flowering duration lasting about 24 days. Four days after flowering, the pollen changes from a mucilaginous to a liquid state and flows to the stigma under the force of gravity. C. shanxiense exhibits high self-compatibility
