Albizia lophanta

Albizia lophanta


Encontramos a espécie no Cabo Mondego nas falésias, perto do Farol. Primeiro pensamos que a espécie seria Acacia dealbata porque são parecidas na morfologia das folhas. No entanto, a flor mostrou que a espécie apresentada será uma espécie do género Albizia, provavelmente Albizia lophanta. Esta espécie está na lista das invasoras em Portugal.

From Wikipédia:

Albizia is a genus of about 150 species of mostly fast-growing subtropical and tropical trees and shrubs in the Subfamily Mimosoideae of the legume family, Fabaceae. The genus is pantropical, occurring in Asia, Africa, Madagascar, Central, South, and southern North America and Australia, but mostly in the Old World tropics. Some species are considered weedy.

They are commonly called silk trees or sirises. Peculiarly, the obsolete form of spelling the scientific name - with double 'z' - has stuck, so that another commonly used term is albizzias (though the form albizias is also found, particularly in species that are not widely known under a common name). The scientific name refers to the Italian nobleman Filippo degli Albizzi, who in the mid-18th century introduced siris to Europe.

These are usually small trees or shrubs with a short lifespan - though the famous Samán del Guère near Maracay in Venezuela is a huge Albizia saman specimen and several hundred years old. The leaves are pinnately or bipinnately compound. Their small flowers are in bundles, with showy stamens much longer than the petals. Confusingly, some species are given the name "mimosa" which correctly belongs to species in the related genus Mimosa. Unlike those of Mimosa, Albizia flowers have much more than 10 stamens. Albizia can also be told apart from another large related genus, Acacia, since its flowers have their stamens joined at the base whereas in Acacia stamens are free (separated).

Persian Silk Tree or Pink Siris (Albizia julibrissin) extends well north into temperate regions in East Asia and is by far the cold-hardiest species. It tolerates temperatures down to about -22°F (-30°C), provided it gets adequate summer heat to ripen the shoots. In North America it is commonly grown as an ornamental tree, but has become naturalized in several US States, and is regarded as an invasive species.

Albizia species are used as food plants by the larvae of some moths of the genus Endoclita inclulding E. damor, E. malabaricus and E. sericeus.
