Taxonomy
Numerous species placed in Albizia by early authors were eventually moved to other genera, most notably Archidendron. Other genera of Ingeae (Abarema, Archidendropsis, Blanchetiodendron, Calliandra, Cathormion, Enterolobium, Havardia, Hesperalbizia, Hydrochorea, Pararchidendron, Paraserianthes, Pseudosamanea and Serianthes) have also received their share of supposed Albizia species, as have the Mimoseae Newtonia and Schleinitzia, and Acacia from the Acacieae. Some presumed "silk trees" are in fact misidentified members of the not very closely related Erythrophleum from the Caesalpinioideae and the Faboideae Lebeckia.
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 probably will continue to do so. These include for example Falcataria moluccana (Moluccan Albizia, formerly Albizia moluccana), a common shade tree on tea plantations. Other closely related genera like Chloroleucon and Samanea are often merged with Albizia entirely.
