Rauvolfia verticillata (Lour.) Baill.??

Flower is not matching dear …, center of my flower is closed,

Appears close to images at Rauvolfia serpentina (L.) Benth. ex Kurz

My ID request 179 is Rauvolfia serpentina, I am sure that this plant have something  difference, so it is not Rauvolfia serpentina, please check collage, 2nd row is 179,

I agree with … for Rauvolfia verticellata,

not only vegetative characters fruit also ovoid …..verticellata
Fruit globose……… serpentaiana.

What is worrying me is the protruding style (?) and pinkish throat which I do not see in Rauvolfia verticillata (Lour.) Baill.

There is another species i.e. Rauvolfia hookeri reported from Kerala as per FoPI.
But I do not find much material or keys to verify or otherwise. Pl. see:
Any clue?

The plant in question is Rauvolfia micrantha Hook.f., a critically endangered and endemic species of Kerala. Attached another photographs here.
