Thanks Ian for the info. Perhaps it's getting too much nutrition. Starvation diet from now on. However the pileatum 'Icy Green' is behaving nicely and has 9 male buds about to open soon. The most consistent and vigorous bloomer Cstm Tengku Zainab Petra has just bloomed with 15 flowers and looks more like its fimbriatum parent. This particular plant responds very quickly to temperature changes and I've had the male, female and hermaphrodite flowers on the same spike just like your sanguineum. My Jumbo Pearl which has produced only female flowers, the last 2 seasons, is going to sleep with me every night in the air-con room when it spikes.
