I am very much sure that *Senegalia catechu*, *Senegalia polyacantha *as
well as *Senegalia chundra* are distinct species.

The calyx of *S. catechu *and *S. polyacantha *are hairy (sometimes
sparsely hairy in *S. polyacantha*); while calyx is completely glabrous in *S.
chundra*

Bark of *S. catechu *and *S. chundra *is very similar. Grey white when
immature while dark brown to black, fissured when mature. *S. polyacantha *bark
is white, papery, peeling out and armed with several, individual, prickles
even on main trunk (probably the name is because of this feature:
poly-a-cantha). Leaves of S. polyacantha are larger than other two species.
Prickles in S. polyacantha is yellowish brown, recurved or straight, and
about 0.5-1.0 cm long, while prickles in other two species are brown to
black, mostly recurved and about 0.3 cm long.

Please find attached pdf of paper by Kshirsagar 2012. He differentiated all
the three species based on morphology.

Thank you.
