The Canellaceae are a family of flowering plants in the order Canellales. [3] The order includes only one other family, the Winteraceae. [4] Canellaceae is native to the Afrotropical and Neotropical realms. They are small to medium trees, rarely shrubs, evergreen and aromatic. [5] The flowers and fruit are often red.
Several species of Canellaceae are important in herbal medicine or as a substitute for cinnamon, which is obtained from genus Cinnamomum in family Lauraceae. Canella winterana is the only species known in cultivation. [6]
The family is divided into five genera, [7] but studies of DNA sequences have indicated one of these genera should be split. [8] These genera together comprise about 25 species. In the Greater Antilles, many of these species are rare and restricted to small ranges. As of 2008, five of the species were newly recognized and not yet named. [8]
Some common properties include: [7] [8] [9]
Synapomorphies for Canellaceae include monadelphous stamens, parietal placentation, and campylotropous ovules. [8]
Other notable traits include the conspicuous lenticels, the aromatic bark, the peppery taste of the leaves, the three (rarely two) fleshy sepals, and the berry with reniform seeds. [8]
Some sources indicate Cinnamodendron has 20-40 stamens, contrary to the sources that are regarded here as reliable. The very large stamen numbers (20 to 40), are probably counts of thecae or microsporangia.
Canellaceae has species in both xeric and wet forests.
In Canella winterana , the flowers are protogynous. The berries are usually red, and probably eaten by birds, which contribute to seed dispersal (ornithochory). The trees are attacked by larvae of different insects, including dipterans.
Monoterpenes are common, as are drimane-type sesquiterpenes, including cinnafragrins, cinnamodial, and capsicodendrin. These three sesquiterpenes are shared with only the Winteraceae in angiosperms. Canellaceae also have alkaloids of the aporphine type, such as N-(cinnamoyl)-tryptamine, lignans of the aryl-tetralin type, cinnamaldehydes, and allylphenols. Crystals of calcium oxalate are in the leaf mesophyll. Most species are cyanogenetic. Protocyanidins, flavonols, saponins, sapogenins, and ellagic acid are absent.[ citation needed ]
The saro, or green sandalwood, (also known locally as mandravasarotra), Cinnamosma fragrans , is native to Madagascar and is exported from there to India to be burned in ceremonies. It is not related to the true sandalwoods, which are in the family Santalaceae.[ citation needed ]
Most species of Canellaceae produce bark that is similar in odor and flavor to cinnamon, but they are closer related to the family Piperaceae including black pepper (Piper nigrum) than to true cinnamons, which are in the family Lauraceae (still within Magnoliids).
The white cinnamon, Canella winterana , a native of Florida and the Antilles, is used as a condiment, with tonic properties.[ citation needed ]
Commercial production of "white cinnamon" from C. winterana has ceased, [11] but small-scale, local production continues. The Canellaceae have long had local use as aromatic plants and as herbal medicines.
The bark of the red cinnamon or false Winter's bark, Cinnamodendron corticosum , is used as a substitute for Winter's bark ( Drimys winteri , a member of Winteraceae) in Chile and Argentina, where it is called canelo, a name that is also applied to cinnamon. In Africa, several species of Warburgia have medicinal uses. The barks of Warburgia salutaris and Warburgia ugandensis are used to treat fevers, colds, and malaria.[ citation needed ] Other species are used for timber or in the production of resins used as glue.[ citation needed ]
Fossil leaves of Canella are known from the Pliocene of Bahia (Brazil).[ citation needed ] Pollen of Pleodendron is known from the Oligocene of Puerto Rico.[ citation needed ]
Depending on the classification system and the characters considered, Canellaceae has been placed close to Annonaceae, Myristicaceae or Winteraceae. [5] In his last book, Armen Takhtajan defined the order Canellales as consisting of Canellaceae and Winteraceae. [9] This circumscription is followed in the APG IV system, in which the order Canellales is sister to another small order, the Piperales. [12] These two orders combined with another two sister-orders Laurales and Magnoliales form together the clade Magnoliids. [13]
In this article, the genus Capsicodendron is maintained in synonymy with Cinnamodendron, although preliminary molecular phylogenetic studies separate Capsicodendron from Cinnamodendron and place Capsicodendron closer to Cinnamosma and Warburgia than to Cinnamodendron. This placement is not corroborated by morphology. The currently recognized genera in Canellaeae can be distinguished as follows: [8]

Canella winterana was an important medicinal plant of the natives of the American tropics, and it was soon adopted as such by the Europeans, as well. Dr. Diego Álvarez Chanca accompanied Christopher Columbus on his second voyage, after which he wrote of a cinnamon (canela in Spanish) which was unlike any of the species of cinnamon used in Europe. [14] He had probably reported the use of C. winterana. [8]
In 1737, in his Hortus Cliffortianus , Linnaeus combined Canella with Drimys , a genus now in Winteraceae, and Cinnamomum , now in Lauraceae , to form a taxon which he called Winterania. [15] In 1753, in the first edition of Species Plantarum , Linnaeus divided Winterania into four species. [16] Three of these are now in Cinnamomum, and the fourth, which he called Laurus winterana, consisted of what are now Canella winterana and Drimys winteri . These four species were included in a broadly defined Laurus .
In 1756, Patrick Browne applied the name Canella to the species now known as Canella winterana. [17] He did not add a specific epithet to create a binomial. [18] The generic name is derived from canela, the Spanish word for cinnamon, but the Spanish word is derived from the Latin canna, meaning "a reed", or from the related Greek kanna, which refers to a piece of rolled bark. [19]
The genus Canella was not adopted by Linnaeus, who resurrected Winterania in the second edition of Species Plantarum in 1762. [20] He assigned to Winterania a single species, Winterania canella, which was equivalent to the species he had previously called Laurus winterana.
In 1784, Johan Andreas Murray divided Winterania into two monospecific genera, the constituent species of which were Canella alba and Wintera aromatica. [21] The name Canella alba was validated by Murray in 1784, [17] but it had long been in use. Linnaeus attributed the name to Samuel Dale, who used it in his Pharmacologia, [15] the first edition of which was published in 1693. [22] Patrick Browne mentions its use by Mark Catesby. [18] Canella alba was renamed as Canella winterana by Joseph Gaertner in 1788 in his classic work De Fructibus et Seminibus Plantarum (The Fruits and Seeds of Plants). [23] The name change was required by the rules of botanical nomenclature. Wintera aromatica is now known as Drimys winteri and is in the family Winteraceae.
The family Canellaceae was established by Carl von Martius in 1832 and was defined as consisting of only the genus Canella. [24] [25] Stephan Endlicher divided Canella in 1840, creating the new genus Cinnamodendron. Cinnamosma was erected in 1867, Warburgia in 1895, and Pleodendron in 1899. Capsicodendron was erected in 1933. Some authors accept Capsicodendron and assign to it two species, Capsicodendron pimenteira and Capsicodendron dinisii. [11] Other authors subsume Capsicodendron into Cinnamodendron and C. pimenteira into C. dinisii. [8]
Molecular phylogenetic studies of DNA sequences have shown Cinnamodendron, as traditionally circumscribed, is polyphyletic, consisting of two distinct groups. [8] These groups are morphologically different and their ranges do not overlap.
One of these groups is related to the African genera Cinnamosma and Warburgia, and might be paraphyletic over them. It consists of eight species, one of which was named in 2005. [26] Two other species in this group have not been formally named and described in the scientific literature. [8] This group is restricted to South America. Since it includes the type species, Cinnamodendron axillare , it will retain the name Cinnamodendron.
The other group of Cinnamodendron species is most closely related to Pleodendron and is restricted to the Greater Antilles. It consists of six species, two of which remain unnamed. [8] The name Antillodendron has been proposed for this group, but this name is considered by some to be invalid because it was not effectively published. [27]
The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek [poly meaning 'many' and gony meaning 'knee' or 'joint']. Alternatively, it may have a different origin, meaning 'many seeds'.
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 Magnoliaceae are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two genera: Magnolia and Liriodendron.
Lythraceae is a family of flowering plants, including 32 genera, with about 620 species of herbs, shrubs, and trees. The larger genera include Cuphea, Lagerstroemia (56), Nesaea (50), Rotala (45), and Lythrum (35). It also includes the pomegranate and the water caltrop. Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well.
The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1,858 accepted species. Examples include horse chestnut, maples, ackee and lychee.
The Primulaceae, commonly known as the primrose family, are a family of herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are perennial though some species, such as scarlet pimpernel, are annuals.
Winteraceae is a primitive family of tropical trees and shrubs including 93 species in five genera. It is of particular interest because it is such a primitive angiosperm family, distantly related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera concentrated in Australasia and Malesia. The five genera, Takhtajania, Tasmannia, Drimys, Pseudowintera, and Zygogynum s.l. all have distinct geographic extant populations. Takhtajania includes a single species, T. perrieri, endemic only to Madagascar, Tasmannia has the largest distribution of genera in Winteraceae with species across the Philippines, Borneo, New Guinea, Eastern Australia, and Tasmannia, Drimys is found in the Neotropical realm, from southern Mexico to the subarctic forests of southern South America, Pseudowintera is found only in New Zealand, and Zygogynum has species in New Guinea and New Caledonia.
Theaceae, the tea family, is a family of flowering plants comprising shrubs and trees, including the economically important tea plant, and the ornamental camellias. It can be described as having from seven to 40 genera, depending on the source and the method of circumscription used. The family Ternstroemiaceae has been included within Theaceae; however, the APG III system of 2009 places it instead in Pentaphylacaceae. Most but not all species are native to China and East Asia.
The water-plantains (Alismataceae) are a family of flowering plants, comprising 20 genera and 119 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are herbaceous aquatic plants growing in marshes and ponds.
Parnassiaceae Gray were a family of flowering plants in the eudicot order Celastrales. The family is not recognized in the APG III system of plant classification. When that system was published in 2009, Parnassiaceae were treated as subfamily Parnassioideae of an expanded family Celastraceae.
Sabiaceae is a family of flowering plants that were placed in the order Proteales according to the APG IV system. It comprises three genera, Meliosma, Ophiocaryon and Sabia, with 66 known species, native to tropical to warm temperate regions of southern Asia and the Americas. The family has also been called Meliosmaceae Endl., 1841, nom. rej.
Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales. It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms. They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies. The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016. Some species are used in traditional medicine. The type genus is Chloranthus. The fossil record of the family, mostly represented by pollen such as Clavatipollenites, extends back to the dawn of the history of flowering plants in the Early Cretaceous, and has been found on all continents.
Peridiscaceae is a family of flowering plants in the order Saxifragales. Four genera comprise this family: Medusandra, Soyauxia, Peridiscus, and Whittonia., with a total of 12 known species. It has a disjunct distribution, with Peridiscus occurring in Venezuela and northern Brazil, Whittonia in Guyana, Medusandra in Cameroon, and Soyauxia in tropical West Africa. Whittonia is possibly extinct, being known from only one specimen collected below Kaieteur Falls in Guyana. In 2006, archeologists attempted to rediscover it, however, it proved unsuccessful.
Eupomatia is a genus of three species of plants in the ancient family Eupomatiaceae, and is the sole genus in the family. Eupomatiaceae is recognised by most taxonomists and classified in the plant order Magnoliales. The three described species are shrubs or small trees, native to the rainforests and humid eucalypt forests of eastern Australia and New Guinea. The type species Eupomatia laurina was described in 1814 by Robert Brown.
Theophrastoideae is a small subfamily of flowering plants in the family Primulaceae. It was formerly recognized as a separate family Theophrastaceae. As previously circumscribed, the family consisted of eight genera and 95 species of trees or shrubs, native to tropical regions of the Americas.
Huerteales is the botanical name for an order of flowering plants. It is one of the 17 orders that make up the large eudicot group known as the rosids in the APG III system of plant classification. Within the rosids, it is one of the orders in Malvidae, a group formerly known as eurosids II and now known informally as the malvids. This is true whether Malvidae is circumscribed broadly to include eight orders as in APG III, or more narrowly to include only four orders. Huerteales consists of four small families, Petenaeaceae, Gerrardinaceae, Tapisciaceae, and Dipentodontaceae.
Geissoloma is a genus of flowering plants in the monotypic family Geissolomataceae, native to the Cape Province of South Africa. Geissoloma marginatum is the only species in the family. It is sometimes called guyalone in English. The plants are xerophytic evergreen shrubs and are known to accumulate aluminum.
Rhodiola is a genus of perennial plants in the family Crassulaceae that resemble Sedum and other members of the family. Like sedums, Rhodiola species are often called stonecrops. Some authors merge Rhodiola into Sedum.
Canella is a monospecific genus containing the species Canella winterana, a tree native to the Caribbean from the Florida Keys to Barbados. Its bark is used as a spice similar to cinnamon, giving rise to the common names cinnamon bark, wild cinnamon, and white cinnamon.
Tetracarpaea is the only genus in the flowering plant family Tetracarpaeaceae. Some taxonomists place it in the family Haloragaceae sensu lato, expanding that family from its traditional circumscription to include Penthorum and Tetracarpaea, and sometimes Aphanopetalum as well.
