I had seen this tree at Chennai. Looks like some Rotaceae sp.
Date/Time: 01-03-2012 / 03:30PM
Location: Gindi park, Chennai
Plant habit: Tree (around 6 m in ht).
Habitat: Not sure (Could be wild??)

Similar looking Ehretia laevis is flowering in Delhi these days on large scale.

Looks like Pamburus missionis. Unable to confirm as the foliage is not clearly seen (arrangement of leaves) . Check the arrangement of leaves and decide whether it is Pamburus missionis or Atlanta manophylla. It is one of these sepcies.

It may be Pamburus missionis as suggested by …

Last year I saw the fruits, having less than an inch diam. Those fruits were few, looked exactly like the fruits … have in efi thread. But, the species should not be same, for stamens are 8 in number and free, at least up to near the base region.
I didn’t see the ripe fruits, so can not tell the colour of ripe fruits or inside pulp.
Found blooming flowers today, other photographs were taken a few days ago.
This is a 10 ft shrub or tree growing in a home yard. The owner said juice of the fruit is fragrant, edible. Flowers have typical citrus smell, rather small than usual citrus, should not be any Citrus species.

I would like to correct myself. Fruits are not eaten as sweet citrus fruits like oranges, but juice, must be small quantity given the fruit size, is used as flavouring agent.

Atalantia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available)

It seems Pamburus missionis (Wight) Swingle, a small tree often found in Chennai area.

Thank you very much …, this is the closest ID possible. I wonder why should someone plant it in his home yard if fruits or flowers seem to be not so popular I think. But, then this looks so close and perhaps there is no alternative.
