This article is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive. The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors.
Acacia nilotica or Vachellia nilotica is a tree 5–20 m high with a dense spheric crown, stems and branches usually dark to black coloured, fissured bark, grey-pinkish slash, exuding a reddish low quality gum. The tree has thin, straight, light, grey spines in axillary pairs, usually in 3 to 12 pairs, 5 to 7.5 cm (3 in) long in young trees ...
Similarly, several Acacia tree species have developed stipular spines (direct defenses) that are swollen at the base, forming a hollow structure that provides housing for protective ants. These Acacia trees also produce nectar in extrafloral nectaries on their leaves as food for the ants. [77] Plant use of endophytic fungi in defense is common.
Senegalia (from Senegal and Acacia senegal (L.) Willd.) [2] is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. [3] [4] The genus was considered polyphyletic and required further division, [4] [5] with the genera Parasenegalia and Pseudosenegalia ...
Senegalia greggii, formerly known as Acacia greggii, is a species of tree in the genus Senegalia native to the southwestern United States and northern Mexico, from the extreme south of Utah south through southern Nevada, southeast California, Arizona, New Mexico and western Texas to Baja California, Sinaloa and Nuevo León in Mexico.
The tree produces a gum in the form of pale yellow small tears of mucilage. [11] [12] This gum (also called gum arabic) is used for emulsification and stabilizing agent in food, cosmetic, textile and pharmaceutical industries. [13] The hard wood of tree is also source of fuel. [14]
