Acaciella angustissima is a short perennial that is woody at least at the base. It does not have spines like the Mimosas. Acaciella angustissima has many small leaflets on each pinna of the compound leaf, and whitish flowers in spherical flowerheads. The pods are flattened, finely veined, and abruptly pointed at the end. The seeds are conspicuously crested and dappled with irregularly shaped light spots. Acaciella angustissima is found on dry, rocky hillsides at middle elevation.
