You have a beautifully grown plant, and the comparison photo with a well known form of B. nodosa is nice to see.

And hence why the cordata was known as such. The plants are endemic to Jamaica and one was found in brazil and then called b. cordata. It was the same species and improperly identified.

Things like that do happen, but that is not quite the case here.
This species, whichever name you know it under, occurs only in the Caribbean. It was apparently given two different names by the same person (Lindley) 5 years apart - Brassavola subulifolia (1831) and Brassavola cordata (1836).
This was probably an honest mistake on his part - simple confusion or the similarities between different specimens not being perfectly obvious when working from dried materials, and individual plants and local forms do vary. He named hundreds of species. He certainly didn't increase his fame or prestige naming one more that particular day.
The first publication was obscure and went unnoticed for the most part. The second publication became widely known and the species was distributed under that name. When the earlier publication was eventually noticed, the rules are clear - the first name given to a species in valid publication is always considered correct. It doesn't matter that a later name had become widely used.

The best single source for this kind of information is probably the Internet Orchid Species Photo Encyclopedia - a website easily found with a search. The information there is factually accurate as far as it goes, but remember that current classification and interpretation is constantly changing and never 'official'. At best it is someone's judgement of information available at a particular time.
