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 Afrotropic and Neotropic ecozones. 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. 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]

Description

The following description is almost entirely from three sources,[7][8][9] but with some information from previous versions of the article.

  • Pollen occurs in monads, and is delicate and monosulcate (usually with 10% of the grain trichotomosulcate); apertures are distal, exine, generally tectate, and granular, intectate, and reticulate in Cinnamosma; grains are small and hardly ornamented in Cinnamodendron and Warburgia, largest and most highly decorated in Canella and Pleodendron. The pollen is generally similar to that of the Myristicaceae, which had at one time caused some systematists to believe the two families were closely related.

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.

Ecology

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-(cinnamoil)-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]

Uses

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 not related to true cinnamons, which are in the family Lauraceae.

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]

Fossils

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]

Systematic position

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 III system, in which the order Canellales is sister to another small order, the Piperales.

Included taxa

Theoretical introduction to Taxonomy

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]

  • Petals fused into a tube to the middle of their length
Cinnamosma Baill., 1867, Madagascar
  • Petals free or slightly connate at the base
* Petals 5, slightly connate at the base, inflorescence a terminal panicle
Canella P. Browne, 1757, Florida, Antilles, northern South America
* Petals 6-12, free, flowers solitary, terminal or axillary, or in axillary inflorescences
* Petals 12, in 3-4 whorls, stamens 12, carpels 6
Pleodendron Tiegh., 1899, Greater Antilles, Costa Rica
* Petals 6-10, in two whorls, stamens 6-10, carpels 2-5(-6)
* Petals 6-10, stamens 6-10, carpels 2-4(-6), leaves elliptic to obovate, ripe fruit up to 2 cm in length
Cinnamodendron Endl., 1840 (including Capsicodendron Hoehne, 1933), Greater Antilles to southern Brazil
* Petals 10, stamens 10, carpels 5, leaves oblanceolate-spatulate to elongate, ripe fruit 3-6 cm long
Warburgia Engl., 1895, eastern and southern Africa

History

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.[12] 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.[13] In 1753, in the first edition of Species Plantarum, Linnaeus divided Winterania into four species.[14] 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.[15] He did not add a specific epithet to create a binomial.[16] 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.[17]

The genus Canella was not adopted by Linnaeus, who resurrected Winterania in the second edition of Species Plantarum in 1762.[18] 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.[19] The name Canella alba was validated by Murray in 1784,[15] but it had long been in use. Linnaeus attributed the name to Samuel Dale, who used it in his Pharmacologia,[13] the first edition of which was published in 1693.[20] Patrick Browne mentions its use by Mark Catesby.[16] 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).[21] 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.[22][23] 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.[24] 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.[25]
