Acacia fasciculifera seedling in the transitional stage between pinnate leaves and phyllodes. The leaves of acacias are compound pinnate in general. In some species, however, more especially in the Australian and Pacific Islands species, the leaflets are suppressed, and the leaf-stalks become vertically flattened in order to serve the purpose of leaves.
The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. [1] The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. [ 2 ]

A number of species, most notably Acacia mangium (hickory wattle), A. mearnsii (black wattle) and A. saligna (coojong), are economically important and are widely planted globally for wood products, tannin, firewood and fodder. [23]
Like other acacias, whistling thorns have leaves that contain tannins, which are thought to serve as deterrents to herbivory. Like all African acacias, they are defended by spines. [11] In addition, whistling thorn acacias are myrmecophytes that have formed a mutualistic relationship with some species of acacia ants.
Catechu (/ ˈ k æ t ɪ ʃ uː / or / ˈ k æ t ɪ tʃ uː /) [1] is an extract of acacia trees used variously as a food additive, astringent, tannin, and dye. It is extracted from several species of Acacia, but especially Senegalia catechu (previously called Acacia catechu), by boiling the wood in water and evaporating the resulting brew. [2]
