I also have a Pot. Little Fortune '#15' - and a Pot. Little Fortune 'NN' - I think I may have posted them about 6 weeks ago or so. The tag is exactly the same as yours. I also googled Paradise Beauty 'Golden Angel' and came up with a lot of results - you might want to check it out.
Oh - and about the Bratonia/Miltassia change - I have NO idea what they were thinking when they changed it - apparently, the hybrid was at one point years back called a Bratonia. Seems to me that if, like mine, your Miltassia has a lot more Miltonia in it than Brassia, the Milt should come first - but of course, that's just logical thinking and we all know they don't necessarily think that way over at the RHS. Seems like there was a powerful Brassia lobbying firm there that day.
