Description

Barbeya oleoides is a small tree, similar to the olive tree. The against-constant leaves are simple, lanceolate and pinnately with smooth margin. The lower leaf surface is hairy white. Stipules absent.

Barbeya oleoides is dioecious getrenntgeschlechtig ( dioecious ). The flowers are pendant together in zymösen inflorescences. Support and cover sheets are missing. The small, functionally unisexual flowers are radial symmetry. The three or four sepals are fused, the sepals are much longer than the calyx tube. Petals absent. In the male flowers, there are usually six to nine (rarely up to twelve) free, fertile stamens with very short filaments. The pollen grains have three apertures and are colporat. There are usually one, rarely two or three upper permanent carpels present, which are fused into an ovary if there is more than one. The carpel is in the apical placentation only a hanging, anatrope ovule available. The long pen are free. Pollination is about the wind ( anemophily ).

The encased by the perianth fruit stands alone or there are two or three together to form a federation and are then fused at their base. Well-trained embryo is straight.

Systematics and distribution

The type Barbeya oleoides was first described in 1892 by Georg August Schweinfurth in Bolle Tino della Società Botanica Italiana, the first publication of the genus name Barbeya took place in the same year by the same author in Malpighia, 5, p 332 and the family Barbeyaceae presented Alfred Barton Rendle, 1916 in Flora of Tropical Africa, 6 ( 2 ), pp. 14.

This type has so far been difficult to classify and so you set for them a monotypic order Barbeyales on or put them inside the Hamamelididae in the Urticales. Today it presents them in the order of Rosales.

Barbeya oleoides is native to northeastern Africa and Arabia.
