The surianaceae are a plant family in the order of the butterfly-like flowers (Fabales). Of the five genera and eight species , three genera with four species occur only in Australia and one genus with three species only in Mexico , a monotypic genus is distributed worldwide on tropical coasts.

description

The family contains only woody plants: trees , bushes . The leaves , arranged in a spiral or in two rows on the branch, are rarely simple, mostly pinnate; the leaflets are arranged alternately on the rhachis . Stipules are missing.

The flowers are arranged in zymose inflorescences . The hermaphrodite, radially symmetrical flowers are five-fold. They each have five sepals and five petals . In two circles they usually have ten, or rarely eight, free stamens . Usually two to five upper carpels are free (apocarp); only in Guilfoylia with the species Guilfoylia monostylis there is only one carpel. The Surianaceae produce berries , drupes or nuts .

Occurrence

The representatives of the family are mainly from Australia. Only the genus Recchia occurs only in Mexico. The species Suriana maritima , however, has a pantropical distribution. They colonize a wide range of habitats from beach vegetation and deserts to tropical rainforests.

Systematics and distribution

The genera of this family were previously classified in the Simaroubaceae family. The Surianaceae family contains five genera with about eight species .

Cadellia F. Muell. : It contains only one type:
- Cadellia pentastylis F. Muell. : It occurs only in New South Wales and Queensland .
Guilfoylia F. Muell. : There is only one carpel. It contains only one type:
- Guilfoylia monostylis (Benth.) F. Muell . (Syn .: Cadellia monostylis Benth. ): It occurs only in New South Wales and Queensland .
