Those are awesome catasetums. Catasetums are some of my favourites too. This seems to be the blooming season for Cstm. My Cstm pileatum ' Icy Green' will be blooming in a few days. This time with 10 flowers ( usually 6-7 ). Unfortunately the pink pileatum had the growing spike eaten by snails but a new spike is coming out about an inch. Hope the snails will not eat this one. 2 other cstm will be blooming soon. One is Cstm Jumbo Pearl but it is dark brown/purple like one of yours. Still can't figure out why it is named Pearl - unless it is meant to be a black pearl! LOL.
