IOSPE is a great source but I have found a few things to be fragrant that are not listed as fragrant there.
No, I have not grown this one. Someone seems to be rebuilding the Angraecum Encyclopedia which is great news. I used it as my guide years ago and then the site went down. It looks like they are starting to include much of the information that once could be found on the old site.
You can use the elevations to look up yearly temperatures and rainfall in Madagascar (or, if African, that part of Africa) which is very useful information. If it grows in Madagascar, it will like good airflow both to the plant and roots as Madagascar is breezy. That is why Angraecums tend to be more prone to fungus attacks. I try to add extra Calcium for these guys.
Good luck!
