attaching images of Acacia horrida from Nashik for validation, please validate
Here the characters are not clear. Hence it is difficult to pinpoint the identity.
Acacia horrida is currently known as Vachellia horrida (L.) Kyal. & Boatwr.
I think these does not match with images at Vachellia horrida (L.) Kyal. & Boatwr. from comparative images at Vachellia (pl. check).
Also pl. check with Vachellia tortilis (Forssk.) Galasso & Banfi
