Medicosma is a genus of shrubs and trees in the family Rutaceae, all native to New Guinea, Australia or New Caledonia. They usually have simple leaves arranged in opposite pairs, flowers arranged in cymes with four sepals, four petals and eight stamens. The fruit is a follicle fused at the base in groups of up to four, each containing one or two brown or black seeds.
Plants in the genus Medicosma are shrubs or trees that usually have simple leaves arranged in opposite pairs but the leaves are sometimes arranged alternately and sometimes trifoliate. The flowers are usually arranged in cymes, sometimes solitary, in leaf axils and are usually bisexual with four sepals, four petals and eight stamens. The sepals are fused at the base and persist in the fruit. The petals are usually free from each other but usually overlap each other slightly. The fruit consists of up to four oval follicles fused at the base, each containing one or two brown to black seeds. [2] [3]
The genus Medicosma was first formally described in 1862 by William Jackson Hooker in Genera Plantarum . [4] [5]
