The flowers appear to be monks wearing cowls and as all Catasetums have the capability of ejecting their pollina [arrow 2 in photo] from the male flower, up to 8 feet with the purpose of depositing it on an insects back that is rummaging around the flower. The photo here shows both male and female flowers and if examined closely [arrow 1 in photo], you can see the pollina within the stigmatic cavity.
