Tabebuia is a neotropical genus of about 100 speciesSteyermark et al. (1997) in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina and central Venezuela, including the Caribbean islands of Hispaniola and Cuba. It is also very common in Brazil, where it's called "Ipe" and it is considered as a Brazilian symbol.
Well-known common names include Ipe, Poui, trumpet trees and '''''pau d'arco'''.
They are large shrubs and trees growing to 5 to 50 m (16 to 160 ft.) tall depending on the species; many species are dry-season deciduous but some are evergreen. The leaves are opposite pairs, complex or palmately compound with 37 leaflets.Tabebuiais a notable flowering tree. The flowers are 3 to 11 cm (1 to 4 in.) wide and are produced in dense clusters. They present a cupular calyx campanulate to tubular, truncate, bilabiate or 5-lobed. Corolla colors vary between species ranging from white, light pink, yellow, lavender, magenta, or red. The outside texture of the flower tube is either glabrous or pubescent.
The fruit is a dehiscent pod, 10 to 50 cm (4 to 20 in.) long, containing numerousin some species wingedseeds. These pods often remain on the tree through dry season until the beginning of the rainy season.
Uses and ecology
Species in this genus are important as timber trees. The wood is used for furniture, decking, and other outdoor uses. It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipe wood had become readily available on the market, although certificates are occasionally forged.Tabebuiais widely used as ornamental tree in the tropics in landscaping gardens, public squares, and boulevards due to its impressive and colorful flowering. Many flowers appear on still leafless stems at the end of the dry season, making the floral display more conspicuous. They are useful as honey plants for bees, and are popular with certain hummingbirds. Naturalist Madhaviah Krishnan on the other hand once famously took offense at ipe grown in India, where it is not native.
The bark of several species has medical properties. The bark is dried, shredded, and then boiled making a bitter or sour-tasting brownish-colored tea. Tea from the inner bark of Pink Ipe (T. impetiginosa'') is known as Lapacho or Taheebo. Its main active principles are lapachol, quercetin, and other flavonoids. It is also available in pill form. The herbal remedy is typically used during flu and cold season and for easing smoker's cough. It apparently works as expectorant, by promoting the lungs to cough up and free deeply embedded mucus and contaminants. However, lapachol is rather toxic and therefore a more topical use e.g. as antibiotic or pesticide may be advisable. Other species with significant folk medical use are T. alba and Yellow Lapacho (T. serratifolia).
Tabebuia heteropoda, T. incana, and other species are occasionally used as an additive to the entheogenic drink Ayahuasca.
Mycosphaerella tabebuiae, a plant pathogenic sac fungus, was first discovered on an ipe tree.
The demand for ipe wood has risen dramatically in recent years, especially in the United States. By the 1990s, numerous environmental organizations working on preservation of the Amazon Rainforest reported that about 80% of logging in the Brazilian Amazon was illegal. The Brazilian government has confirmed this figure, most notably in a leaked report from the Brazilian Intelligence Agency, in which it was confirmed that five times the amount of wood sanctioned to be cut from legal Amazon concessions was being exported and that numerous staff of the environment agency IBAMA were taking bribes.
In an October 2001 study for Greenpeace, five companies were reported to be logging illegally for ipe and other hardwoods in the region around Santarem, Para: Cemex Commercial Madeiras Exportacao, Madeireira Santarem (Madesa), Industrial Madeireira Curuatinga, Maderieira Rancho da Cabocla, and Estancia Alecrim/Milton Jose Schnorr. The bulk of their illegal timber exports from that region went to the Netherlands and France.
Much of the ipe imported into the United States is used for decking. Starting in the late 1960s, importing companies targeted large boardwalk projects to sell ipe, beginning with New York City Department of Parks and Recreation ("Parks") which maintains the city's boardwalks, including along the beach of Coney Island. The city began using ipe around that time and has since converted the entire boardwalkover 10 miles (16 km) longto ipe. The ipe lasted about 25 years, at which time (1994) Parks has been replacing it with new ipe. Given that ipe trees typically grow in densities of only one or two trees per acre, large areas of forest must be searched to fill orders for boardwalks and, to a lesser extent, homeowner decks.
In 2008-2009 Wildwood, New Jersey rebuilt a section of their boardwalk using ipe, the town had pledged to use domestic black locust, but it was not available in time.
Nowadays, ipe wood from cultivated trees supersedes timber extracted from the wild. As noted above, customers should check for legitimacy of certificates.
