The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe. Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
Xanthosoma is a genus of flowering plants in the arum family, Araceae. The genus is native to tropical America but widely cultivated and naturalized in other tropical regions. Several are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, cocoyam, tannia, tannier, yautía, macabo, ocumo, macal, taioba, dasheen, quequisque, ʻape and as Singapore taro. Many other species, including especially Xanthosoma roseum, are used as ornamental plants; in popular horticultural literature these species may be known as ‘ape due to resemblance to the true Polynesian ʻape, Alocasia macrorrhizos, or as elephant ear from visual resemblance of the leaf to an elephant's ear. Sometimes the latter name is also applied to members in the closely related genera Caladium, Colocasia (taro), and Alocasia.
Cryptocoryne is a genus of aquatic plants from the family Araceae. The genus is naturally distributed in tropical regions of India, Southeast Asia and New Guinea.
Anthurium is a genus of about 1,000 species of flowering plants, the largest genus of the arum family, Araceae. General common names include anthurium, tailflower, flamingo flower, pigtail plant, and laceleaf.
Gonatopus is a genus of flowering plants in the family Araceae, consisting of about five species. This genus is native to eastern and southeastern Africa and is closely related to the genus Zamioculcas. The plant generally only produces one leaf from its tuber when in growth. In G. boivinii, the leaf is tripinnate, and with its stalk can reach up to 1 m in height and 40 cm broad; the individual leaflets are up to 10 cm long and 3.5 cm broad; in G. angustus, the leaf can reach 1.5 m tall. A spadix arises from the tuber during late spring.
Carlephyton is a genus of four species in the family Araceae, all endemic to Madagascar.
Ambrosina is a genus in the family Araceae that consists of only one species, Ambrosina bassii, and the only genus in the tribe Ambrosineae. This species is the smallest terrestrial aroid in the Mediterranean, growing only to 8 cm tall. It is usually found growing in woodlands on north faces of hillsides and in humus soil that is covering limestone. It is distributed in Sardinia, Corsica, Sicily, southern mainland Italy, Tunisia, and Algeria.
Aroideae is a subfamily of flowering plants in the family Araceae. It is the largest subfamily in Araceae and consists of about 72 different genera, and 2,300 species. Many Aroideae have spiny pollen grains without a sporopollenin outer exine layer and lacking an aperture.
Orontium aquaticum, sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the family Araceae. It is the single living species in the genus Orontium, which also contains several extinct species described from fossils. O. aquaticum is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix.
Urospatha is a genus of flowering plants in the family Araceae that consists of 11 known species. They are found growing in South America and Central America in swamps, wet savannahs, and brackish water. The leaves of the species in this genus are upward pointing and sagittate (arrow-shaped). The inflorescences are quite unique; the spathe is mottled and elongated with a spiral twist at the end. The seeds are distributed by water and have a texture similar to cork that allows them to float. They also quickly germinate in water.
Hendrik (Henk) Cornelis Dirk de Wit was a Dutch systematic botanist who contributed significantly to the knowledge of the Aroid genera Cryptocoryne and Lagenandra. He grew up in the Waterland, a marshy area in the Northwest Netherlands, and had a lifelong interest in aquatic plants.
Remusatia is a genus of flowering plants in the family Araceae. It contains 4 known species, one of which was described in 1987. This species was initially placed in genus Gonatanthus called Gonatanthus ornatus. After the genus had been sunk into Remusatia its new name was Remusatia ornatus, but it was later changed to Remusatia hookeriana.
Lagenandra dewitii is an aquatic to semi-aquatic flowering plant species belonging to the aroid genus Lagenandra. It was first described in 1986, from living plants and dried herbarium material, and named in honour of Dutch botanist Hendrik de Wit.
The Anubiadeae are a tribe of the family Araceae, subfamily Aroideae. The tribe was first described in 1879 by Adolf Engler and contained only the genus Anubias Schott. In 1915, Engler added the genus Amauriella Rendle. The two genera were distinguished by the position of the thecae on the synandria. The latest taxonomic revision regards Amauriella as a synonym of Anubias, leaving this a monogeneric tribe. The Anubiadeae are aquatic and semi-aquatic plants and are native to tropical central and western Africa. They primarily grow in rivers and streams, but can also be found in marshes.
Anubias heterophylla is a species belonging to the Aroid genus Anubias. It was first described scientifically by Adolf Engler in 1879.
Anubias gigantea is an aquatic to riparian aroid species belonging to the genus Anubias, within the Araceae. It was first mentioned by Auguste Chevalier in 1920, based on material that he had collected in Guinea, West Africa. The formal description followed in 1939 by John Hutchinson. It is closely related to A. afzelii, basically only differing from that species by the form of the leaf-blade, with mature growth appearing somewhat different than the juvenile plants.
Arie de Graaf is a Dutch insurer, biologist, teacher, and politician.
Anubias pynaertii is a species belonging to the Aroid genus Anubias. It was first described scientifically by Émile Auguste Joseph De Wildeman in 1910, based on material collected in Zaire by, among others, Léon Auguste Edouard Joseph Pynaert, after whom the species was named.
Anubias hastifolia is a species belonging to the Aroid genus Anubias. It was first mentioned by Adolf Engler in 1889 and described scientifically by him in 1893.
