It is an Epidendrum. It seems there are a few Epidendrum secundum types, ( lower case implies species) depending where in South America you look. I would think you look at small local differences, hence secundum is many times referred to as secundum type complex.
I wouldn't know what exactly applies to your plant, is it secundum type species, or is it a very closely related hybrid with a secundum type.
One thing is certain, it is not radicans or ibaguense.
