Barbeya oleoides is a small tree that resembles the olive tree . The opposite leaves are simple, lanceolate and pinnate with a smooth leaf margin. The underside of the leaf is hairy white. Stipules are missing.
Barbeya oleoides is dioeciously segregated ( diocesan ). The flowers are laterally together in zymose inflorescences . Support and cover sheets are missing. The small, functionally unisexual flowers are radial symmetry . The three or four sepals are fused, with the calyx lobes being significantly longer than the calyx tube. Petals are missing. In the male flowers there are usually six to nine (rarely up to twelve) free, fertile stamens with very short stamens. The pollen grains have three apertures and are colporat. There are usually one, rarely two to three upper carpels , which have grown together to form an ovary if there is more than one. There is only one hanging, anatropic ovule per carpel in apical placentation . The long styluses are free. Pollination takes place via the wind ( anemophilia ).
The fruit, enveloped by the flower cover, stands alone or two to three are joined together to form a bandage and are then fused at their base. The well-formed embryo is straight.
Systematics and distribution
The species Barbeya oleoides was first described in 1892 by Georg August Schweinfurth in Bolletino della Società Botanica Italiana , the first publication of the generic name Barbeya took place in the same year by the same author in Malpighia , 5, p. 332 and the Barbeyaceae family placed Alfred Barton Rendle in Flora in 1916 of Tropical Africa , 6 (2), p. 14.
This species was previously difficult to classify, and therefore a monotypical order of Barbeyales was established for it or it was placed in the Urticales within the Hamamelididae. Today they are placed in the order of the Rosales .
