Bignoniaceae

Tabebuia sp = Androanthus albus (Cham.) Mattos

Lapacho amarillo (Spanish)

Ipe amarelo da serra (Portuguese)

Native tree to Argenitne and Brazil

Agreed Bignonoaceae is correct. sorry for my mistake 

thanks Prasad N V Majeti and Marcela Buyatti

The tree is Tabebuia alba  ( syn : Handroanthus albus)  of the Bignoniaceae family. Of course, it native to Brazil; mostly an ornamental tree for urban tree planting as well as medicinal plant to some extent.

In any case Tabebuia (Bignoniaceae), possibly T. chrysantha, the yellow-flowering species. My source gives a tree of 6 m tall, from Venezuela, flowering when leafless.

Definitely a Tabebuia sp. I have seen the golden yellow ones listed as T. chrysantha but also other names.  Both T. alba and Handroanthus albus look to be the same. I would like to see them side by side if they are not all the same species. It would be good to know the small differences.  Absolutely a beautiful tree when it blooms which name you call it.

Surely a Tabebuia tree of Bignoniaceae

Tabubia argentea-Bignoniaceae Road side tree

Common name in Brazil is "Ipê amarelo".

It is Handroanthus chrysotrichus (Mart. ex DC.) Mattos of the Bignoniaceae family. The native range of this deciduous tree species is Brazil to Northeast Argentina. It is often confused with Handroanthus ochraceus (Cham.) Mattos

Thanks!
