It is a perennial, deciduous, and belongs to the family Fabaceae (beans/legumes) and as it grows it starts as a shrub but eventually matures to a small tree.

The tree has a high density of leaves along with small clumps of white flowers and creates 4–7 cm long seed pods.

Acaciella angustissima is found in tropical areas around the equator since its water needs can vary from 750 to 2,500 mm a year.

Aside from being drought tolerant, A. angustissima also has the benefit of being a green manure, since it has such a high leaf density, but also loses the majority of its leaves each season.

Acaciella angustissima is normally a shrub but can also look like a small tree when fully grown, since its height can vary from 2–7 m depending on the growing conditions.

Luckily there is hope, roughly 20 years ago researches started evaluating it in tropical areas such as Zimbabwe.

[5] The only times it should be considered are when dealing with a harsh conditions where only weeds can survive, and some type of ground cover is needed to help with erosion control.

Intercropping would also be complementary, by allowing farmers to take advantage of the unused space between plants, the nitrogen fixing habit, and the shade provided by the bushy branches.

[9] Acaciella angustissima should be planted in March or April in soil that has good drainage and is more on the acidic side on the pH scale.

[7] The indigenous Tzotzil and Tzeltal Maya people of Mexico use A. angustissima to treat digestive tract problems.
