| I don't know precisely when the RHS adopted Encyclia for registration purposes, but I am fairly sure it was some point within my orchid-life, meaning some point after about 1996 or so. When I started getting involved in showing orchids and judging (which was somewhere around 1999 or so) at which point it was necessary for me ot know proper names, Encyclia were called Encyclia by most everyone but the generic name Epidendrum was still used to register hybrids. When the first mass distributed/cloned Encyclia/Cattleya crosses (Epicat. El Hatillo 'Pinta' for one) became widely available (I noticed them in numbers around the turn of the millenium), the genus Epicattleya was still being used by the RHS meaning they had not yet switched to using Encyclia. It has only been since i moved here to Australia (2004), and even more so only in the last year or so I have seen the intergeneric name Catyclia. So, I think it has been a fairly recent adoption.
Lollipop and other formerly Epicatts like El Hatillo (reg. 1977) were probably correctly registered as Epicattleya back then as tampensis was, at least for hybrid registration purposes, an Epidendrum at that time. Now that the RHS recognizes Encyclia for tampensis, all crosses between it and various cattleyas have been changed retroactively.
