Description

All species are evergreen, woody plants: trees or shrubs. The branches are plagiotrop ( plagiotrop: by geotropism certain growth direction that is not the orientation of the shoot axis ) aligned. The alternate, distichous, closely arranged in short shoots (looks like a feathery leaf ) leaves are simple. The leaf margins are smooth, sawn or perforated. There are Stipules present.

They are usually dioecious getrenntgeschlechtig ( dioecious ). The flowers are borne singly or in differently constructed inflorescences. The small flowers are unisexual and usually radial symmetry fünfzählig. There are five sepals and petals present. The male flowers contain one, two or three circles, each with five free, fertile stamens. In the female flowers two to five carpels are fused to a syncarp, superior ovaries, with two to five free pencils. Are formed drupes.

Systematics and distribution

The family has a disjoint area: home ranges of taxa are located in West Africa and Southeast Asia to New Guinea and the Solomon Islands.

In the family of Pandaceae there are only three genera with 15-28 species. The three genera were formerly in the tribes Galearieae in the subfamily Acalyphoideae within the family of Euphorbiaceae:

  • Galearia inches. & Mor. (including Bennettia R.Br. and Cremostachys Tul. ): The approximately 14 species come from Indochina to the Solomon Islands.
