Acacia (genus Acacia) is a genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae, first described in Africa. The leaves of acacias are compound pinnate in general, the small flowers have five very small petals, almost hidden by the long stamens. The plants often bear spines, especially those species growing in arid regions.
Acacia was a type of wood used in the creation of wands. Garrick Ollivander found that wands made from Acacia were difficult to match with a wizard. Acacia wands generally refused to produce magic for anyone but their owners, but conversely, seemed to withhold their full power from all but the most gifted wizards. As such, Ollivander only kept a small supply of Acacia wands in his shop. Owners of Acacia wands were generally subtle wizards, as wands made from this wood were generally unsuitable for what Ollivander termed "bangs-and-smells magic".
