Xylomancy was an "often overlooked" type of divination that relied upon twigs.[1] The book Xylomancy by Selina Sapworthy covered it,[1] and at least once, a class in the art was taught in the North Tower at Hogwarts.[2] In 1926, Ilvermorny School of Witchcraft and Wizardry offered an extracurricular class in Xylomancy.[3]
