Falcataria moluccana, commonly known as the Moluccan albizia, is a species of fast-growing tree in the legume family, Fabaceae. It is native to New Guinea, Maluku Islands, the Solomon Islands, and the Bismarck Archipelago in Papua New Guinea, and is cultivated for timber throughout South Asian and Southeast Asian countries. This tree is considered to be invasive in Hawaii, American Samoa and several other island nations in the Pacific and Indian Oceans. It is about 30m tall tree in nature with a massive trunk and an open crown.
Falcataria moluccana Wikipedia
Falcataria moluccana is cultivated throughout the wet tropical and subtropical regions of the world and so has many common names. These include: albizia (Hawaii), Moluccan albizia, sengon (Java), batai (Malaysia), sau and falcata.Leaves - twice pinnately compound with small leaflets
Flowers - creamy white small flowers are faintly fragrant
Fruits - pods
Uses - soft wood is used for make match sticks of match boxes. Pulp is used for paper-making.
The tree has become invasive in forests in Hawaii and on other Pacific islands.
In Hawaii the caterpillars of the endemic Hawaiian koa looper (Scotorythra paludicola) has been found to defoliate Falcataria moluccana and complete their development on this invasive tree without the larvae eating the leaves of their native host Acacia koa.
In Borneo the following moth species have been identified as feeding on Falcataria moluccana.Lymantria brunneiplaga - Family Lymantriidae
Hypochrosis cryptopyrrhata - Family Geometridae
Erygia spissa - Family Erebidae
Hypopyra pudens - Family Erebidae
In the broader Indomalayan region the following species have also been found feeding on F. moluccana:Charaxes bernardus - Lepidoptera: Family Nymphalidae
Falcataria moluccana is the primary host of the gall rust fungus Uromycladium falcatarium, and has also been recorded as a host of Uromycladium tepperianum. Both of these gall rust species cause severe damage throughout all stages of the tree's growth.
Two Actinomycetales bacteria Streptomyces asiaticus and S. cangkringensis have been isolated from the rhizosphere soil surrounding F. moluccana in Indonesia. Although at least 10 species of Streptomyces are plant pathogens it is unclear if these two species have any negative impacts on the roots or other tissues of this tree.
