According to folk tradition, this ghost appears as a young woman that haunts wild banana trees (Musa balbisiana), known in Thai language as Kluai Tani (กล้วยตานี).

This ghost inhabits the clumps of wild banana trees and is popularly represented as a beautiful young woman wearing a green traditional Thai costume.

In some modern representations the lower part of her body is represented with an immaterial quality, her waist cloth ending in a kind of wisp emanating from the tree trunk.

[6] Their leaves are commonly used in Thailand to wrap locally produced sweets and the inflorescence for the treatment of ulcers in traditional medicine.

[9] Some people tie lengths of colored silk around the trunks of the banana trees reputed to be haunted by Nang Tani.

In the PC MMORPG Ragnarok Online, Nang Tani is inspiration of the MVP boss character Lady Tanee of the Ayothaya Dungeon.
