Falcataria falcata is the primary host of the gall rust fungus Uromycladium falcatarium, [17] and has also been recorded as a host of Uromycladium tepperianum. [18] Both of these gall rust species cause severe damage throughout all stages of the tree's growth.
An alternative basionym must be sought or a new name created. The correct name is Falcataria falcata (L.) Greuter & R.Rankin. [11] The four names Adenanthera falcataria, Albizia falcataria, Paraserianthes falcataria and Falcataria falcata can each be correct given different taxonomic opinions that put the plant in each of these four genera ...
Falcataria falcata had previously been classified within the genera Adenanthera, Albizia, and Paraserianthes before being moved to the new genus Falcataria, as the most widely distributed of the three species in the genus. [6] [4] This widely cultivated timber tree is still called by the common name "albizia" in Hawaii and elsewhere.
Cream albizia (A. adianthifolia) Albizia amaraThere are approximately 99 accepted species in the legume tree genus Albizia, the silk trees, sirises, or albizias. [1]Numerous species placed in Albizia by early authors were eventually moved to other genera, particularly Archidendron and many other Ingeae, as well as certain Acacieae, Mimoseae, and even Caesalpinioideae and Faboideae.
The delimitation of Falcataria and Pithecellobium, close relatives of Albizia, is notoriously complex, with species having been moved between the genera time and again, and this will likely continue. These include Falcataria falcata (the Moluccan albizia, formerly named Albizia moluccana), a common shade tree on tea plantations.
Falcataria gall rust fungus (Uromycladium falcatarium) is potentially specific to only one host plant, Falcataria moluccana.However, U. falcatarium is closely related to the acacia gall rust fungus U. tepperianum, which has almost 100 known hosts including plants from several tribes of Mimosoideae.

Extremophile is the term that covers a large group of organisms, most prominently Archaeans, which have evolved to fill the niches of extremely inhospitable environments. Such environments include high or low temperatures, high levels of salinity, high or low pH levels, and areas where volatile chemicals are prominent.
