    Premna?? 

    Very vague to guess for me, however, can I take chance with Premna integrifolia L. ???

    efi page on Premna serratifolia (syn: Premna integrifolia L.)
    Premna species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net)
    Can it be Premna integrifolia ?
    Does not matches with images at Premna serratifolia L.
    Looks like matching with P. integrifolia.
    The plant list says P. serratifolia is synonym of P. integrifolia.
    But does not look like matching with P. serratifolia.
    Calyx look much different from images given at my stated link: Premna serratifolia L.
