Cypripedium formosanum

The Formosan lady's slipper or beautiful cypripedium, Cypripedium formosanum, is a species of orchid endemic to Taiwan.

This species is restricted to the central mountains of Taiwan, where it grows in several types of habitat in mountain forests and bogs. It is associated with species of ferns, Epimedium, Trillium, and Podophyllum, and Diphylleia grayi. It is also cultivated, being attractive and easy to grow and propagate. This is especially true of in vitro efforts as researchers have been able to calculate an ideal Germination rate, 90 days after planting (DAP), which can help address the population decline issues within this species. Furthermore, the IUCN Red List suggests specific conservation actions for this species in order to reduce the harms they face such as climate change and human disturbance to their natural habitat.
