|Tecoma chrysostricha (left) and Cattleya labita (right)|
According to sources that I found, Brazil seems to have two flowers it holds in national regard. The first, Tecoma chrysostricha is called the "National Flower Emblem" of Brazil. The second, Cattleya labita, is often called the "State Flower" of Brazil. Slightly confusing, but I guess the ust couldn't decide between the two. Tecoma chrysotricha, also known as Ipe-amarelo (caled so by the indigenous peoples of Brazil) is the flower of a native, broad-leafed tree that is found in the decidous forests of South America. It belongs to the tropical family of bignonias that has over four hundred species found in Brazil. It gained prominence when it was made the national flower emblem by President Quadros.Cattleya labita, also known as the corsage orchid, is very popular in festivals in Brazil. It primarily grows in the northeastern part of Brazil where it was discovered in 1818.
Erythrina cristina galli, also known as the ceibo or Cockspur Coral Tree, was declared the national tree and flower of Argentina on December 2nd, 1942. This species in the Fabaceae family usually grows in forests along waterways and in swamps and wetlands. The tallest varieites are found in the Argentine provinces of Salta, Jujuy and Tucuman.
