Canellales is the botanical name for an order of flowering plants, one of the four orders of the magnoliids. It is recognized by the most recent classification of flowering plants, the APG IV system. It is defined to contain two families: Canellaceae and Winteraceae, which comprise 136 species of fragrant trees and shrubs. The Canellaceae are found in tropical America and Africa, and the Winteraceae are part of the Antarctic flora. Although the order was defined based on phylogenetic studies, a number of possible synapomorphies have been suggested, relating to the pollen tube, the seeds, the thickness of the integument, and other aspects of the morphology.
The Santalales are an order of flowering plants in the dicotyledons. Well-known members of the Santalales include sandalwoods and the many species of mistletoes. The order has a cosmopolitan distribution, but is heavily concentrated in tropical and subtropical regions. It derives its name from its type genus, Santalum (sandalwood).
The Cornales are an order of flowering plants, early diverging among the asterids, containing about 600 species. Plants within the Cornales usually have four-parted flowers, drupaceous fruits, and inferior to half-inferior gynoecia topped with disc-shaped nectaries.
Proteales is an order of flowering plants consisting of three families. The Proteales have been recognized by almost all taxonomists.
The Francoaceae are a small family of flowering plants in the order Geraniales, including the genera Francoa, commonly known as bridal wreaths. The Francoaceae are recognized as a family under various classification schemes. Under the 2009 APG III system the Francoaceae were included within the Melianthaceae. In the 2016 APG IV system the Francoaceae are again recognized as a family, with Melianthaceae included in the circumscription of Francoaceae.
The Aquifoliales are an order of flowering plants, including the Aquifoliaceae (holly) family, and also the Helwingiaceae and the Phyllonomaceae. In 2001, the families Stemonuraceae and Cardiopteridaceae were added to this order. This circumscription of Aquifoliales was recognized by the Angiosperm Phylogeny Group when they published the APG II system in 2003. In the Cronquist system, there is no Aquifoliales order: the Aquifoliaceae are placed within the order Celastrales and the others are in other families.
The Zygophyllales are an order of dicotyledonous plants, comprising the following two families:
Haemodoraceae is a family of perennial herbaceous angiosperms containing 15 genera and 102 known species, sometimes known as the "bloodroots", found throughout the Southern Hemisphere, from Australia and New Guinea to South Africa, as well as the Americas.
Pontederiaceae is a family of flowering plants.
Saururaceae is a plant family comprising four genera and seven species of herbaceous flowering plants native to eastern and southern Asia and North America. The family has been recognised by most taxonomists, and is sometimes known as the "lizard's-tail family". The APG IV system assigned it to the order Piperales in the clade magnoliids.
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade. Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades, the common sunflower, petunias, yacon, morning glory, lettuce, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, blueberries, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.
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.
Myrothamnus is a genus of flowering plants, consisting of two species of small xerophytic shrubs, in the southern parts of tropical Africa and in Madagascar. Myrothamnus is recognized as the only genus in the family Myrothamnaceae.
In plant taxonomy, commelinids is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. Well-known commelinids include palms and relatives, dayflowers, spiderworts, kangaroo paws, and water hyacinth, grasses, bromeliads, rushes, and sedges, and ginger, cardamom, turmeric, galangal, bananas, plantains, and bird of paradise flower.
Hanguana is a genus of flowering plants with a dozen known species. It is the only genus in the family Hanguanaceae.
Philydraceae is a family of flowering plants composed of three genera and a total of six known species. Such a family has not been recognized by many taxonomists.
Tecophilaeaceae is a family of flowering plants, placed in the order Asparagales of the monocots. It consists of nine genera with a total of 27 species.
Huaceae is a family of plant in the rosids group, which has been classed in the orders Malpighiales, Malvales, and Violales or in its own order Huales. The APG II system placed it in the clade eurosids I, whereas the APG III system of 2009 and APG IV (2016) place it within the Oxalidales. The family is endemic to central Africa. It contains four species in the following two genera:
Icacinales is an order of flowering plants.
