Hoya aldrichii , commonly known as the Christmas Island Waxvine is a species of flowering plant in the Apocynaceae or dogbane family. It is a vine that is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean, where it is a common epiphyte in the shrublands of the island’s coastal terraces. The specific epithet honours Captain Aldrich, commander of the survey vessel HMS Egeria, which visited Christmas Island in 1887.
