Scyphiphora hydrophyllacea C.F. Gaertn. or Chengam is a non-viviparous evergreen tree species. The flowers are bisexual, self-compatible, self-pollinating, temporally dioecious and exhibit a mixed breeding system.  The plant is both melittophilous and anemophilous at the study area.  Natural fruit set is 100% but seeds are non-viable which might be due to a genetic disorder.
