Based on this single images, it appears to be incorrect.

May I request you to give your views in this matter pl.

Osbeckia octandra
sensu Clarke, is distributed only in Sri lanka, Ceylon. In FOI all images shown under Osbeckia octandra is Osbeckia virgata D. Don ex Wight & Arn.
Osbeckia virgata and O. octandra are closely related. They are easily recognized from other species in their area by their general appearance. But they may be confused with O. brachystemon, O. parvifolia and O. moonii when one has to decide their identity by means of differential characters. O. virgata and O. octandra differ from these by the usually much sparser vestiture of the hypanthium; by the almost thread-like intersepalar emergenoes with 1 to few bristles, or by the much reduced intersepalar emergences; and by the deciduous sepals.
I am attaching few images

That’s right. Osbeckia octandra is found only in Sri Lanka. So, the FOI specimen must be Osbeckia virgata.

Requesting a herb ID_110422-4:  2 high res. images.

A handsome herb with pink flowers, leaves alternate with characteristic three venations.
Bonacaud, Adjoining Agasthyamalai.

Osbeckia octandra L. ??

Looks different from images at Osbeckia octandra DC.
Could not find a match as per comparative images at Osbeckia

O. virgata

Could you please tell me the key characters to differential O. octandra and O. virgata

If you check both species in efi, you can notice the clear difference, in particular w.r.t. the hairs on the calyx, habit of the plant and shape of the leaves.

Please identify this Shrub from a hillock at Kozhikode district of Kerala. 4/11/22

Melastoma malabathricum

Since stamens are of isomorphous type it may not be Melastoma

To me appears close to images at

Osbeckia virgata D. Don ex Wight & Arn.
