Cattleya trianae (Lind. & Rchb. fil), also known as Flor de Mayo ("May flower") or "Christmas orchid", [2] is a species of flowering plant in the family Orchidaceae . [1] [3] It grows as an epiphytic orchid, with succulent leaves, endemic to Colombia where it was nominated as the national flower in November 1936. That year, the National Academy of History of Argentina asked the Latin American countries to participate in an exhibition with the representative flowers of each country. The Colombian government gave the botanist Emilio Robledo the task to designate the most representative flowering plant of the country.

The choice of Cattleya trianae was made for two main reasons:

The species grows at 1500–2000 meters above sea level, in Cloud forests. It is an endangered species due to habitat destruction. [4]

The diploid chromosome number of C. trianae has been determined as 2n = 40. the haploid chromosome number has been determined as n = 20. [5]
