Castes and Tribes of Southern India/Banni or Vanni
Banni or Vanni (Prosopis spicigera). — An exogamous sept of Kuruba and Kurni. The tree is worshipped because on it "the five Pāndava princes hung up their arms when they entered Virāt Nagra in disguise. On the tree the arms turned to snakes, and remained untouched till the owners returned." (Lisboa.)
