Description

Pittosporaceae are dioecious trees, shrubs, or twining vines, with leaves having pinnate venation, no stipules, and margins that are smooth.[5] Ovaries are superior, often with parietal placentation.[5] The style is undivided and straight, and the stigma is often lobed.[5] The fruit is a capsule or berry with the calyx being shed from the fruit.[5] The seeds are surrounded by sticky pulp that comes from secretions of the placental hairs.[5] The flowers have equal numbers of sepals, petals and stamens.[5]
