Approximately 100 speciesthroughout the Old and New World tropics; in Malesia 13 species.

Taxonomy

1 There remains some debate as to whether Tabernaemontana is monophyletic. In particular it is possible that the New World species of Tabernaemontana are more closely related to some of the genera that have not been synonymised into Tabernaemontana than they are to the Old World species of Tabernaemontana (Mary Endress, pers. com.). This may eventually lead to the genus being made larger to accommodate these other genera or to the splitting up of the genus into smaller monophyletic genera. 2 Species delimitation is rather difficult in Tabernaemontana and there has been some debate as to whether the broad species concepts adopted by Leeuwenberg (1991) should be followed. This is particularly true for T. pandacaqui which has an extremely extensive synonymy. The account here is largely adapted from Leeuwenberg (1991) rather than having been completely reworked. I have not listed all the synonyms for each species and the reader is referred back to Leeuwenberg.
