    I thought this one was still considered a Laelia Zainal?

    The natural hybrid Cattleya x dayana, and the registered hybrid Cattleya Dayana are C. forbesii x C. gutatta (or vice versa). But this plant, formerly known as Laelia dayana, is now Cattleya bicalhoi. It couldn't be C. dayana after the switch because that name was already taken.

    So call it Laelia dayana or Cattleya bicalhoi, depending on your ability to deal with change, and this is a lovely example of the species either way. Cattleya dayana it is not.

    The only bit of your post which causes me any problem is the bit I quote.
    You see, I have seen several cases where, after the name changes, tye Register does end up with several quite different plants, all with the same name. What has been done then is add the year of the registration as an extra, so we have , lets say Onc Charlesworthii 1911, and Onc Charlesworthii 1927 etc. ( These are not precise examples, although Onc. Charlesworthii is a case in point.
    But the ways of taxonomic botanists are a perpetual sourceof irritation !

    That is indeed the case for registered hybrids, and under the control of RHS Orchid Register which is the official hybrid register for orchids. They chose to add the year as a way to distinguish hybrids that were given the same grex name and ended up in conflict because of later change in genus. That is a horticultural issue and falls under the rules of The International Code of Nomenclature for Cultivated Plants. As the recognized registration authority RHS makes the rules for registered man-made orchid hybrids within what is allowed in the Code.

    Naming of species or natural hybrids is a taxonomic/botanical issue, and falls under The International Code of Botanical Nomenclature. Laelia dayana and Cattleya x dayana were not in conflict under those rules because the genus was different. When the genus for L. dayana was changed to Cattleya, the older name C. x dayana had precedence under Cattleya, and L. dayana needed a new name. Such a change would be published just as any other botanical name, and C. bicalhoi was created.
