State the tree of Rajasthan :

Amrita Devi of Khejarli village and her three young daughters laid down their lives to protect the sacred tree. This inspired other members of the community and a total of 363 people sacrificed their lives in coming days trying to save the trees by hugging them while the king’s men chopped their bodies with axes. From that incident, Khejri or Prosopis cineraria is the state tree of Rajasthan.
