Eurya sandwicensis is the only native species of this family.

Young 'anini look very similar to forest 'ohelo when not flowering. However, it has smoother glossier leaves, smoother tan bark, and grows into a tree. Small trees tend to be scrawny, with long slender limbs - much more upright than bushy forest 'ohelo. Large trees have numerous small branches densely packed with small leaves, a bit like a bristly pipe-cleaner, often with distinctly pale new growth at the tips.

'Anini is listed as rare, but it is found on several islands and it tends to be locally common in places where its colonies are found. The two most numerous populations I have access to are along Stainback Highway near Pu'u Maka'ala Army Road and in the forests and kipukas near Kaumana Trail on the windward Saddle. There are certainly many other populations in similar habitats across the windward side of the island.
