Cadellia

Cadellia is a monotypic genus of trees in the botanical family Surianaceae. The sole species, Cadellia pentastylis, commonly known as ooline, is a medium to large tree with bright green leaves and rough tile-pattern bark. It has rain forest origins dating from the Pleistocene Era when much of Australia was wetter than it is today. It grows on moderately fertile soils, preferably those suited for agriculture or pasture development. Due to extensive forest clearing, it is now considered a vulnerable plant in Australia.

== Description == The Cadellia tree grows to be about 10 m—rarely 25 m in height. It has leaves that are alternate, undivided and obovate or oval in shape. Flowering occurs from about October to December. The flowers have five white petals, about 5-7 mm in length. The ooline's fruit is brownish, wrinkled, and remains surrounded by five red sepals at its base. Fruiting generally occurs from November to December. The fruit's edibility for humans is not stated.
