An unusual species (some consider a separate genus Cattleyella), Cattleya araguaiensis, intriguing 4.5-5" fragrant flowers with a most unusual lip which does not unfurl much, but has its own particular form of beauty. Like Laelia (syn.cattleya?) lundii and C.walkeriana, these and other unique species make one wonder about the relationships in their groups. Are unifoliate and bifoliate catts all really the same genus? Are all the large floofy ones really just one big species when even the 'experts' cannot tell them apart? Do C.walkeriana and C.nobilior belong in their own separate genus? How big do we want a genus to be if it is no guide to the morphology and culture of the plants within it? Sophronitis also comes to mind, as do the rupicolous 'laelias'.
