Tabernaemontana alternifolia is a species of plant in the family Apocynaceae. It is endemic to India.
The name Tabernaemontana heyneana Wall. has often been used for this species, and a proposal was made to conserve that name so that it would be used instead of T. alternifolia.[1] Arguments made for conservation were that the type of the species was not a specimen but an illustration, and that the plant has opposite leaves, not alternate leaves as alternifolia implies.[1] However, the proposal was rejected, and the correct name of this species is the original name, T. alternifolia.[2]
