Request Tree ID 0006: In lalbagh, looks similar to ‘crape jasmine’ Tabernaemontana Divaricata


NO this is not TAGAR… a very popular bush with white flowers in Calcutta gardens and streets, and almost all over the world , gardeners love it in warm climates or for green houses,    Tabernaemontana Divaricata does not have such large prominent green calyx as in your picture….
This is reminiscent of some wrightia, they often have white flowers and prominent green calyx..


For me looks like Gardenia sp. of family Rubiaceae (coffee family)


I looked in wiki for gardenia, nothing matches the flower I have.
I did talk the guys in the lalbagh registrar office, who said they will put a name plate.


It look like some Tabernaemontana species (or may be hybrid) in Family Apocynaceae.. It definately dont look like any Gardenia sp. or Family Rubiaceae..


Come to think of it….
I have seen this flower and plant.. short shrub in the gardens of a Jain temple in Bihar, a few years ago…. in APril, was quite hot by then…flower fragrant when it opens and stays fragrant for a couple of hours in the am…. did not have a camera with me… but the intrigue has stayed with me… mostly for the semblance to tagar but not quite tagar…
the slightly undulating edges of the leaves and its size etc … and the green corollla more prominent than
Tabernamontana divaricata …makes me think it might be one of the Stemmadenia as in Stemmadenia litoralis


efi thread
Is it Vocanga africana ?


In the photographs it is not very clear, but if interpetiolar stipules are there then undoubtedly it is a Rubiaceae member. Otherwise possibility of Wrightia/ Holarrhena (Apocynaceae) can not be ruled out.


In the first picture there is one lone flower on the bottom left side of the photograph which looks very much like Tabernaemontana Divaricata. Has this flower fallen there? The other flowers definitely do not look like Tabernaemontana Divaricata.


It looks like Pootia grandiflora


The leaf arrangement and branching looks like a Rubiaceae shrub or treelet.


It is Vocanga africana, I confirmed with the Lalbagh curators


Here are the fruits
