Diagnostics:
On first glance, Schizolobium parahyba look somewhat like a prehistoric tree. It is usually single-stemmed or sparsely branching from the individuals I have observed in Singapore, though photos of it in other countries showed that it can be otherwise. The large bipinnate leaves are arranged spirally near the tips of the branches, and the stem is very prominently marked by leaf scars.
Interesting Facts:
The Brazilian Fern Tree is a very fast growing tree species, with a growth rate of about 2m a year as recorded in one study (Piotto et al., 2004). It's unique form and splash of yellow flowers during its seasonal blooms makes it a popular cultivated tree at gateways and entrances.
