I would like to bring back some interrogation about Phragmipedium exstaminodium, I did read an old but very interesting thread and discussion concerning the caudatum alliance… I did miss that one too... And I would like to know what you are thinking about this specie now. I did read on that thread, than some of you are considering extaminodium as a mutation of popowii...? It was my first opinion and I was convinced abut that too. But when it blooms two years ago my opinion did change.... There is much more difference in the flower than just the lack of the staminode... Exstaminodium pouches opening are rounder and wider at the junction of petals. The petals are wide like ribons and hold horizontally looks like it protecting the pouch opening. Petals and ventral are much shorter. The popowii pouches are more oval and thinner at the junction of petals. The petals are thinner too and hold vertically like shoulders each side of the pouch and they are very long. The dorsal and ventral are long. Did anybody have pictures of that specie for comparaison...?
