When you typed 'orchids' it gave you everything that had it as a common or cultivar name, often it becomes a color name, that's why you will find daylilies, roses, etc. You have to actually search by the genus type (Phalaenopsis, Cattleya, Epidendrum etc.) to get it to be all orchids. You can perhaps pick one genus at a time and see what comes up.
I wouldn't want that job either, those names are all crazy sounding to me!!
I need simple.
