This seems to be Erythrina suberosa (E. stricta var. suberosa is a synonym) 
- most prominent indicator is pubescent leaves which I think can help 
distinguish from E. stricta ( as given by Hooker - v.2 page 189  and 
Brandis - page 227). I could not decipher many typical taxonomic terms used 
in these texts (Probably Dr. Gurcharan Singh can help in that and find some 
more distinguishing features) 

However, there are many confusing characteristics in these species. One my 
earlier posts was sort of inconclusive 
(https://groups.google.com/forum/?hl=en&fromgroups#!topic/indiantreepix/5wkiyksq50M).

The tree on right side in my earlier post also has some similar 
characteristics to the one above but there are some deviations also like 
spine characteristics and glands on petiole.

Pradeep Krishan in 'Jungle trees of Central India' - page 371-72 has also 
left this issue unresolved but it is obvious that there are many 
overlapping/ mixed characters - bark being the most confusing.

I found a reference describing natural hybridization within Section 
Erythrina 
(https://ia700703.us.archive.org/34/items/cbarchive_120964_experimentalstudiesonspeciesre1988/experimentalstudiesonspeciesre1988.pdf)

Both E. suberosa and E. stricta belong to section Suberosae and if section 
Erythrina can have interspecific hybrids, chances in section Suberosae are 
also high.

It is more likely that we have such hybrids.
