Illicium is a genus of flowering plants treated as part of the family Schisandraceae, [2] or alternately as the sole genus of the Illiciaceae. [3] It has a disjunct distribution, with most species native to eastern Asia and several in parts of North America, including the southeastern United States, Mexico, and the Caribbean. [4] General common names include star anise [5] and anisetree. [2] The genus name comes from the Latin illicere ("to allure"). [5]
Illicium species are evergreen shrubs and small trees. The leaves are alternately arranged and borne on petioles. The blades are glandular and fragrant. The flowers are solitary. They have few to many tepals in two or three rows, the inner ones like petals and the outer ones often smaller and more like bracts. A few to many stamens and pistils are at the center. The fruit is an aggregate of follicles arranged in a star-shaped whorl. One seed is in each follicle, released when the follicle dehisces. The seed has a thick, oily endosperm. [6]
These are plants of moist understory, adapted to shady habitat, and some species are so sensitive to light that too much sunlight causes them significant stress, manifesting in chlorosis and necrosis of the leaves. [7]
Several species are cultivated as ornamental plants for their flowers, foliage, and fragrance, leading to the development of several cultivars. [8] Many taxa can only be grown in low-light situations. [7]
The essential oils of several species are used as flavorings and carminatives; however, the oils of I. anisatum and I. floridanum are toxic. I. verum, the common star anise, is used to flavor food and liquor. Its fruit is a traditional Chinese medicine called bājiǎo huíxiāng (八角茴香), which is used to treat abdominal pain and vomiting. [6]
Illicium is a notably difficult genus to taxonomically classify. Many of the currently recognized species lack distinguishing characters, and treatments tend to list many synonyms. Additionally, herbarium material is often poorly preserved or scarce. [9]
As of August 2024 [update] , Plants of the World Online accepted these species: [1]
Illicium verum is a medium-sized evergreen tree native to northeast Vietnam and South China. It is a spice that closely resembles anise in flavor and is obtained from the star-shaped pericarps of the fruit of I. verum which are harvested just before ripening. Star anise oil is a highly fragrant oil used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. Until 2012, when they switched to using genetically modified E. coli, Roche Pharmaceuticals used up to 90% of the world's annual star anise crop to produce oseltamivir (Tamiflu) via shikimic acid.
Antidesma is a genus of tropical plant in the family Phyllanthaceae formally described by Linnaeus in 1753. It is native to tropical Africa, S + E + SE Asia, Australia, and various oceanic islands. The greatest diversity occurs in Southeast Asia.
Arisaema is a large and diverse genus of the flowering plant family Araceae.
Gaultheria is a genus of about 283 species of shrubs in the family Ericaceae. The name commemorates Jean François Gaultier of Quebec, an honour bestowed by the Scandinavian Pehr Kalm in 1748 and taken up by Carl Linnaeus in his Species Plantarum. These plants are native to Asia, Australasia and North and South America. In the past, the Southern Hemisphere species were often treated as the separate genus Pernettya, but no consistent reliable morphological or genetic differences support recognition of two genera, and they are now united in the single genus Gaultheria.
Tainia, commonly known as ribbon orchids or 带唇兰属 is a genus of about thirty species of evergreen, terrestrial orchids in the distributed from India, China, Japan, Southeast Asia to New Guinea, the Solomon Islands and Queensland.
Illicium anisatum, with common names Japanese star anise, Aniseed tree, and sacred Anise tree, known in Japanese as shikimi, is an evergreen shrub or small tree closely related to the Chinese star anise. Since it is highly toxic, the fruit is not edible; instead, the dried and powdered leaves are burned as incense in Japan. Its branches and evergreen leaves are considered highly sacred by Japanese Buddhists due to insects' aversion to them and their ability to remain fresh after pruning.
Illiciaceae A.C.Sm. was a family of flowering plants recognized in a number of systems of plant taxonomy. The Illiciaceae is not recognized as a distinct family by the APG III system of plant taxonomy, the most well accepted system in use today.
Phoebe is a genus of evergreen trees and shrubs belonging to the Laurel family, Lauraceae. There are 75 accepted species in the genus, distributed in tropical and subtropical Asia and New Guinea. 35 species occur in China, of which 27 are endemic. The first description of the genus was of the type species P. lanceolata made in 1836 by Christian Gottfried Daniel Nees von Esenbeck in Systema Laurinarum, p. 98.
Disporum is a genus of about 20 species of perennial flowering plants, found in Asia from northern India to Japan, south to Indonesia and north into the Russian Far East.
Anodendron is a genus of plant in the family Apocynaceae first described as a genus in 1844. It is native to most of tropical Asia: China, the Indian subcontinent, Southeast Asia, New Guinea, and some islands of the western Pacific.
Illicium floridanum is an evergreen shrub native to the Gulf Coast area of the Southern United States, from Florida to Louisiana.
Illicium parviflorum, commonly known as yellow anisetree, yellow-anise, swamp star-anise, and small anise tree, is a species of flowering plant in the family Schisandraceae, or alternately, the Illiciaceae. It is native to Florida in the United States. It historically occurred in Georgia as well, but it has been extirpated from the state.
Pholidota, commonly known as rattlesnake orchids, is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are clump-forming epiphytes or lithophytes with pseudobulbs, each with a single large leaf and a large number of small, whitish flowers arranged in two ranks along a thin, wiry flowering stem that emerges from the top of the pseudobulb. There are about thirty five species native to areas from tropical and subtropical Asia to the southwestern Pacific.
Eremochloa is a genus of Asian and Australian plants in the grass family.
Merrilactone A is one of the four sesquiterpenes that were newly discovered from the fruit of Illicium merrillianum in 2000. Members of the genus Illicium include Chinese star anise, widely used as a spice for flavouring food and beverages, and also poisonous plants such as Japanese star anise. Chemical studies of Illicium have developed rapidly over the last 20 years, and merrilactone A has been shown to have neurotrophic activity in fetal rat cortical neuron cultures. This has led researchers to believe that Merrilactone A may hold therapeutic potential in the treatment of neuro-degenerative diseases such as Alzheimer's disease and Parkinson's disease.
Urceola is a plant genus in the family Apocynaceae, first described as a genus in 1798. It is native to China, the Himalayas, Southeast Asia, and New Guinea.
Callicarpa (beautyberry) is a genus of shrubs and small trees in the family Lamiaceae. They are native to east and southeast Asia, Australia, Madagascar, south-eastern North America and South America.
Gomphostemma is a genus of flowering plants in the mint family, Lamiaceae, first described in 1830. It is native to Southeast Asia, China, and the Indian subcontinent.
