The Stemonuraceae are a family within the flowering plants (Magnoliopsida).
description
The species in the family are woody plants: trees and shrubs . The alternate, simple leaves are often stalked and leathery. Stipules are missing.
They are usually dioeciously separated sexes ( diocesan ). Zymous inflorescences are formed. The small, non-fragrant, radial symmetry flowers are four to five-fold (rarely up to seven-fold). The sepals are more or less free. The petals are fused. There is only one stamen circle with strong, often noticeably hairy stamens (filaments). The carpels are a top permanent ovary grown, with a wide, sitting scar. There are drupes formed.
Systematics and distribution
The taxa have their home in the tropics. The center of biodiversity is the Pacific region from Southeast Asia to Queensland (Australia). A few species are found in the Neotropic , on the Indian subcontinent and in Africa including Madagascar .
Some authors place these taxa in the Icacinaceae Miers family. The Stemonuraceae family contains about twelve genera with about 80 species:
