Hoya aphylla (Apocynaceae, Asclepiadoideae), a new leafless species from Laos

A new leafless species of Hoya, Hoya aphylla, has been discovered in Hin Nam No National Protected Area, Laos. This unique find stands out due to its distinct floral morphology and corona characteristics, which differentiate it from similar species like H. lyi, H. carnosa, and H. multiflora. While it shares some traits with the type section of the genus Hoya, its leafless habit sets it apart, making it a notable addition to the region's flora. The discovery highlights the biodiversity richness of UNESCO World Heritage Sites like Phong Nha-Ke Bang National Park and Hin Nam No National Park.
