Hoya is a genus of over 500 species of plants in the dogbane family, Apocynaceae, commonly known as waxflowers. Plants in the genus Hoya are mostly epiphytic or lithophytic vines, rarely subshrubs, with leathery, fleshy or succulent leaves, shortly tube-shaped or bell-shaped flowers with five horizontally spreading lobes, the flowers in umbels or racemes, and spindle-shaped or cylindrical to oval follicles containing flattened egg-shaped to oblong seeds.
