Rhabdodendron is a genus of flowering plant in the family Rhabdodendraceae . [1] [2] It comprises three species of tropical South American trees. [1]
It is placed in its own family, Rhabdodendraceae, which has only been recognized for the past few decades. The 2003 APG II system (unchanged from the 1998 APG system) assigned it to the order Caryophyllales in the clade core eudicots. The 1981 Cronquist system placed it in the order Rosales. Before the creation of the family Rhabdodendraceae, the genus Rhabdodendron had a very lively history as to taxonomic placement.
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the Eucalyptus grandis genome in June 2014.
Rosales is an order of flowering plants. It is sister to a clade consisting of Fagales and Cucurbitales. It contains about 7,700 species, distributed into about 260 genera. Rosales comprise nine families, the type family being the rose family, Rosaceae. The largest of these families are Rosaceae (91/4828) and Urticaceae (53/2625). The order Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families.
The Vitaceae are a family of flowering plants, with 14 genera and around 910 known species, including common plants such as grapevines and Virginia creeper. The family name is derived from the genus Vitis.
The Buxales are a small order of eudicot flowering plants, recognized by the APG IV system of 2016. The order includes the family Buxaceae; the families Didymelaceae and Haptanthaceae may also be recognized or may be included in the Buxaceae. Many members of the order are evergreen shrubs or trees, although some are herbaceous perennials. They have separate "male" (staminate) and "female" (carpellate) flowers, mostly on the same plant. Some species are of economic importance either for the wood they produce or as ornamental plants.
The Restionaceae, also called restiads and restios, are a family of flowering plants native to the Southern Hemisphere; they vary from a few centimeters to 3 meters in height. Following the APG IV (2016): the family now includes the former families Anarthriaceae, Centrolepidaceae and Lyginiaceae, and as such includes 51 genera with 572 known species. Based on evidence from fossil pollen, the Restionaceae likely originated more than 65 million years ago during the Late Cretaceous period, when the southern continents were still part of Gondwana.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics comprising c. 175 genera and c. 5115 known species. Melastomes are annual or perennial herbs, shrubs, or small trees.
Austrobaileya is the sole genus consisting of a single species that constitutes the entire flowering plant family Austrobaileyaceae. The species Austrobaileya scandens grows naturally only in the Wet Tropics rainforests of northeastern Queensland, Australia.
Dilleniaceae is a family of flowering plants with 11 genera and about 430 known species. Such a family has been universally recognized by taxonomists. It is known to gardeners for the genus Hibbertia, which contains many commercially valuable garden species.
Achariaceae is a family of flowering plants consisting of 31 genera and about 155 species of tropical herbs, shrubs, and trees. The APG IV system has greatly expanded the scope of the family by including many genera previously classified in Flacourtiaceae. Molecular data strongly support the inclusion of this family in the order Malpighiales.
Trimeniaceae is a family of flowering plants recognized by most taxonomists, at least for the past several decades. It is a small family of one genus, Trimenia, with eight known species of woody plants, bearing essential oils. The family is subtropical to tropical and found in Southeast Asia, eastern Australia and on several Pacific Islands.
Euptelea is a genus of two species of flowering plants in the monogeneric family Eupteleaceae. The genus is found from Assam east through China to Japan, and consists of shrubs or small trees:
The Rapateaceae are a family of flowering plants. The botanical name has been recognized by most taxonomists.
Ancistrocladus is a genus of woody lianas in the monotypic family Ancistrocladaceae. The branches climb by twining other stems or by scrambling with hooked tips. They are found in the tropics of the Old World.
The Molluginaceae are a family of flowering plants recognized by several taxonomists. It was previously included in the larger family Aizoaceae. The APG III system of 2009 made no change in the status of the family as compared to the APG II system of 2003 and the APG system of 1998, apart from a reassignment of several genera, such as the placement of Corrigiola and Telephium into Caryophyllaceae, Corbichonia in Lophiocarpaceae, Microtea into Microteaceae and Limeum in Limeaceae, because the family was found to be widely polyphyletic in Caryophyllales. In addition Macarthuria was found not to be related to Limeum as previously thought and thus it was placed in Macarthuriaceae, and similarly species formerly placed in Hypertelis, apart from type species Hypertelis spergulacea, a true Molluginaceae, were found to belong elsewhere and were described as Kewa in the family Kewaceae, named for the Royal Botanic Gardens Kew. Molluginaceae is still assigned to the order Caryophyllales in the clade core eudicots, although the generic circumscription is difficult because Mollugo is not monophyletic.
Loasaceae is a family of 15–20 genera and about 200–260 species of flowering plants in the order Cornales, native to the Americas and Africa. Members of the family include annual, biennial and perennial herbaceous plants, and a few shrubs and small trees. Members of the subfamily Loasoideae are known to exhibit rapid thigmonastic stamen movement when pollinators are present.
Hoplestigma is a genus of flowering plants in the family Boraginaceae, although this is disputed, and it has been placed in its own family Hoplestigmataceae. Its two species are native to Cameroon, Gabon, Ivory Coast and Liberia in western tropical Africa.
Caryophyllales is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae.
