The generic name has sometimes been spelt Aegialites[
This species is very similar to Aegialitis rotundifolia, differing mainly in the smaller flowers and also in its preferred habitat[
Aegialinites annulatus C.Presl
A small mangrove that grows in exposed sites. These ones are about half a metre tall and form a miniature forest at Charles Point, NT Australia. During high tide they will be completely submerged.

Aegialitis annulata is an evergreen shrub growing from 30 - 300cm tall[
The plant is sometimes harvested from the wild as a source of tannins for local use.
This species is relatively widespread and common. It is threatened by the loss of mangrove habitat throughout its range, primarily due to extraction and coastal development, and there has been an estimated 24% decline in mangrove area within this species range since 1980. Mangrove species are more at risk from coastal development and extraction at the extremes of their distribution, and are likely to be contracting in these areas more than in other areas. It is also likely that changes in climate due to global warming will further affect these parts of the range. Although there are overall range declines in many areas, they are not enough to reach any of the threatened category thresholds. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[
