The following species and natural hybrids in the flowering plant genus Ilex, the hollies, are accepted by Plants of the World Online. [1] Ilex has the most species of any woody dioecious angiosperm genus. [2]
Some artificial hybrids are also known, including: [3]
Schradera is a genus of flowering plants in the family Rubiaceae. It was described by Martin Vahl in 1797. The genus has a wide distribution area and is found from tropical America to the Malay Archipelago. It is the only genus in the tribe Schradereae.
Brunellia is a genus of trees. They are distributed in the mountainous regions of southern Mexico, Central America, West Indies, and South America. Brunellia is the only genus in the family Brunelliaceae. As of 2001 there were about 54 species.
Glyptopetalum is a genus of plant in the family Celastraceae.
Gymnosporia is an Old World genus of plants, that comprise suffrutices, shrubs and trees. It was formerly considered congeneric with Maytenus, but more recent investigations separated it based on the presence of achyblasts and spines, alternate leaves or fascicles of leaves, an inflorescence that forms a dichasium, mostly unisexual flowers, and fruit forming a dehiscent capsule, with an aril on the seed. It is dioecious, with male and female flowers on separate plants.
Salacia is a genus of plants in the family Celastraceae. They are woody climbers naturally found in tropical regions.
Daphnopsis is a plant genus in the family Thymelaeaceae. There are 50 to 65 species distributed in the Neotropics. They are shrubs and small trees with tubular or bell-shaped flowers. Individuals are dioecious, with male and female flowers produced on separate trees.
Connarus is a genus of plants in the family Connaraceae.
Tetrapterys is a genus of flowering plants in the family Malpighiaceae, native to Latin America and the Caribbean, from Mexico through to Argentina, but excluding Chile. Small trees, shrubs or vines, they are known to be toxic to livestock if consumed for long periods of time, and T. mucronata and T. styloptera have hallucinogenic effects in humans similar to ayahuasca.
