"Tabebuia" is a
neotropical genusof about 100 speciesSteyermark "et al." (1997)] in the tribe Tecomeaeof the family Bignoniaceae. The species range from northern Mexicoand the Antillessouth to northern Argentina, including the Caribbeanislands of Hispaniola( Dominican Republicand Haiti) and Cuba. Well-known common names include Ipê, 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 deciduousbut some are evergreen. The leaves are opposite pairs, complex or palmately compound with 3-7 leaflets.
"Tabebuia" is 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 glabrousor pubescent.
fruitis a dehiscentpod, 10 to 50 cm (4 to 20 in) long, containing numerous - in some species winged - seeds. 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
timbertrees. The wood is used for furniture, decking, and other outdoor uses. It has a fire rating of A1 (the highest possible, the same as concrete), [Wood Addicts' Guide Book: [http://www.woodsthebest.com/ipe_decking/ipe-wood.htm Ipe Lumber Fact Sheet] . Retrieved 2008-JAN-27.] and is denser than water (it sinks). It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipê wood had become readily available on the market, although certificates are occasionally forged. [ FSC Watch: [http://www.fsc-watch.org/archives/2007/08/22/SmartWood_misled_US_local_authority_over_FSC_timber SmartWood misled US local authority over FSC timber] . Posted 2007-AUG-22. Retrieved 2008-JAN-27.]
"Tabebuia" is 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. [Baza Mendonça & dos Anjos (2005)] Naturalist Madhaviah Krishnanon the other hand once famously took offense at ipé grown in India, where it is not native.
barkof 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 Ipê("T. impetiginosa") is known as Lapachoor Taheebo. Its main active principles are lapachol, quercetinand 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 mucusand contaminants. However, lapachol is rather toxic and therefore a more topicaluse e.g. as antibioticor pesticidemay 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. [Ott (1995)]
Mycosphaerella tabebuiae", a plant pathogenic sac fungus, was first discovered on an ipê tree.
The demand for ipê wood has risen dramatically in recent years, especially in the
United States. By the 1990s, numerous environmental organizations working on preservation of the Amazon Rainforestreported 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 IBAMAwere taking bribes. [SAE (1997)]
In an October 2001 study for
Greenpeace, five companies were reported to be logging illegally for ipê and other hardwoods in the region around Santarém, Pará: Cemex Commercial Madeiras Exportaçao, Madeireira Santarém( Madesa), Industrial Madeireira Curuatinga, Maderieira Rancho da Caboclaand Estância Alecrim/ Milton José Schnorr. The bulk of their illegal timber exports from that region went to The Netherlandsand France. [Marquesini & Edwards (2001)]
Much of the ipê imported into the
USis used for decking. Starting in the late 1960s, importing companies targeted large boardwalkprojects to sell ipê, beginning with New York City Parks and Recreation("Parks") which maintains the city's boardwalks, including along the beachof Coney Island. The city began using ipê around that time and has since converted the entire boardwalk— over 10 miles (16 km) long — to ipê. The ipê lasted about 25 years, at which time (1994), Parks has been replacing it with new ipê. Given that ipê trees typically grow in densities of only one or two trees per acre, large areas of forest must be logged to fill orders for boardwalks and, to a lesser extent, homeowner decks.
A 1998 study for
Rainforest Reliefstated that at one time average yields were 76 board feet per acre (44 m³/km²) of FEQ (first export quality — FAS four-side-clear) grade ipê over seven feet (2.1 m) in length. Typically, wooden boardwalks are composed of 30,000 to 40,000 board feet (70 to 90 m³) per city block. For New York City's 10 miles (16 km) of boardwalk, this would yield an estimate of 83,360 acres (337 km²) of Amazon rainforestlogged. [Keating (1998)]
Nowadays, ipé wood from cultivated trees supersedes timber extracted from the wild. As noted above, customers should check for legitimacy of certificates.
