The Crypteroniaceae are a family of plants in the order of the myrtle-like (Myrtales). They have a purely palaeotropic distribution.


The species in this family are evergreen trees and shrubs . Young twigs are often square. The short-stalked leaves are arranged opposite to one another, like most other myrtle-like species . The simple leaf blades are leathery. Stipules are tiny or only rudimentary .

Many flowers are in axillary, racemose , spiked or paniculate inflorescences . The flowers are hermaphroditic or unisexual, if they are unisexual, then the plants are dioeciously separated ( dioecious ). The small flowers are radial symmetry and usually four to five-fold, rarely six-fold. A hypanthium is formed. Sepals are present in all genera. Petals are absent in Crypteronia , are present in the other genera. Usually there is only one circle with four or five, rarely six free fertile stamens ; in Axinandra there are two circles, each with five free, fertile stamens. The anthers are small. The two to five carpels are one above to below permanent ovary grown. In each flower there is only one stylus with a mostly heady stigma .

There are fruit capsules formed to 100 seeds contain. The small seeds are wingless or have one or two membranous wings.


The Crypteroniaceae family was established in 1868 by Alphonse Louis Pierre Pyrame de Candolle in Augustin Pyramus de Candolle & Alphonse Louis Pierre Pyrame de Candolle: Prodromus Systematis Naturalis Regni Vegetabilis , 16 (2), p. 677. Type genus is Crypteronia Blume .

Within the order of the Myrtales, Crypteroniaceae are most closely related to the families of the Penaeaceae from southern Africa and Alzateaceae from the Neotropics . It is believed that their common ancestor lived in western Gondwana during the Cretaceous Period . The Crypteroniaceae drifted northward with the Indian subcontinent after the supercontinent broke up. Before the collision with Asia, the three genera arose and then spread to today's area: in Southeast Asia , the Malay Archipelago and Sri Lanka .

The family Crypteroniaceae contains three genera with about twelve species:
