Requesting to please provide ID of the plant.
This is a Bonsai of a Premna in Mumbai.
The leaves are very glossy and thickish. The original size of the leaves is around 7-8 cm (in as much as I have seen), but due to constant pruning, the new leaves can grow upto 3-4 mm only.
I have not seen this flower, but have heard that it does flower.
The suggested ID is Premna obtusifolia, is is possible to validate it based on the bonsai version?
