Pl. go through ‎Combretum (‎‎‎Combretaceae) page with images of species (mainly done by …) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.
Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.

It has been found that the Combretum wallichii complex (with spines on the main body of the fruits) comprises some closely related species, treated as varieties of C. wallichii by Gangopadhyay and Chakrabarty (1997), differing from each another with narrow differences.  Hence Combretum wallichii var. flagrocarpum should now be considered as a distinct species, Combretum flagrocarpus C.B.Clarke.

Gangopadhyay & Chakrabarty (1993) reduced Combretum flagrocarpus C.B. Clarke to a variety of C. wallichii DC. However, Chakrabarty & Chauhan (J. Econ. Taxon. Bot. 28: 126-127. 2004) wrote: “Gangopadhyay & Chakrabarty (1993, 1997) applied a rather wide concept while treating C. wallichii by reducing four well established species viz. C. flagrocarpum Clarke, C. griffithii Heurck & Mull.Arg., C. porterianum (Wall. ex C.B. Clarke) Craib and C. yunnanense Exell as its varieties. They also proposed a new variety, var. deciduum , under C. wallichii. It appears that the superficially similar foliage and the difficulty in identifying the incomplete materials of the taxa under discussion possibly prompted Gangopadhyay & Chakrabarty to make such drastic reductions. However, the present studies reveal that C. wallichii in its present state (i.e. sensu Gangopadhyay & Chakrabarty, 1993) represents a heterogeneous assemblage and in fact six closely related species are involved in it rather than varieties with clear-cut differences from each another without any intergradations. Hence it seems appropriate and convenient to remove all the varieties from C. wallichii and reinstate or raise them to specific ranks, following the traditional treatments….”
Here, Chakrabarty & Chauhan (2004) then reinstated Combretum flagrocarpum C.B. Clarke and clarified that it can be distinguished from C. wallichii in being pubescent and in the absence of tufts of yellow hairs or domatia on the lower nerve-axils on the undersurface of the leaves.
Now the present images show dense linear-subulate persistent processes on the main body of the fruits which point to C. wallichii as well as C. flagrocarpum.  However, as the nature of pubescence is not clear in the images (whether pubescent or glabrous) as well as whether the lower surface of the leaves bearing domatia in the lower nerve axils.  In any case, in its present concept, Combretum wallichii is endemic to Nepal and C. flagrocarpum is distributed in Bhutan, NE India, Bangladesh and Myanmar.
Conclusion: Combretum flagrocarpus C.B. Clarke.

Combretaceae ? Combretum ?
I think a similar plant was identified earlier. Not able to recollect it now.

Maybe yes but without close up of flowers (whether 4-merous or 5-merous) difficult to say.

Can you post a clear image showing the flowers?

There is a possibility of Terminalia also.

Sorry ! Not available cleared photo showing individual flowers

I am not finding a match as per comparative images at Combretum
What are the keys?
Or is it some other genus or family?

After checking all the species, I think Combretum roxburghii Spreng., is a close possibility as per GBIF specimen- one.

On further checking, it appears more closer to Combretum wallichii var. flagrocarpum (C.B.Clarke) M.G.Gangop. & Chakrab., as per GBIF specimens- one, two, three.
