Vincetoxicum rupicola is a species of plant in the dogbane family Apocynaceae that is endemic to Queensland, Australia. ^[1] It was first described by Paul Irwin Forster in 1992 as Tylophora rupicola. ^[2]

Distribution and habitat

The species is known from the Wet Tropics of north-eastern Queensland, where it grows among grass and rocks above permanent water in grassy open forests of Allocasuarina torulosa , Eucalyptus granitica and Corymbia rhodops on granitic soils. ^[3]
