There seems to be some grumbling surrounding the names of a couple of orchids I just posted so let's see if I can at least explain what is going on. The first was a Cattleya hybrid named Rhyncholaeliocattleya [Rlc.] Fatari. Last year or so, it would have been called Blc. Fatari, but one of the parents had its name changed from a Blc. to an Rlc. The other parent is a species Cattleya so no problem there. I can trace the problem back 7 generations to a digbiana, whose name was changed from Brassavola to a Rhyncholaelia, thus from a B to an R. Digbiana is such a popular orchid that it has been used in thousands of hybrids so when I see a Blc, I can suspect that it is now an Rlc. So, this one name change has affected 7 generations of names. The name itself is telling us that this orchid is an intergeneric hybrid made by crossing a Rhyncholaelia with a Cattleya. Looking at the profile, Rlc. Fatari is made up of 50% C. walkeriana, 25% C. warscewiczii, and 25% mutt.
Now for the Myc. Luster. The parents are (Cattleya forbesii x Myrmecophila thomsoniana). So, we have a species Cattleya crossed with a species Myemecophila which tells us right away that this is a primary hybrid (the product of two species orchids). Now remember that Myrmecophila is a boffin name for Schomburgkia so what we really have is a Schombocattleya. I hope this helps.
