Its look quite similar to Exacum tenue but the shape of the anther are different. The photos of online observation show anther which becomes thinner towards the end while my observations (at least 4 different indivu) shoes anther more regulary shaped.

Ill try to take a sample at the next rainy season here

Thank you

Here is the best "whole plant" photo I have. For the leaves you can look at the picture above.  It's an mycoheterotrophic species

[Saroj Kasaju]

There are no leaves ?

Thank you.

Except the little transparent bract / leave in the picture there is no clear leaf organ as the plant is supposed almost not to photosynthesize

Thank you
