Isn't this similar to (or even identical) to cleistogamous flowering in some
dicots ? eg our UK Wood Sorrel that rarely sets seed from the flowers in the
spring but does from later flowers that never open. Some labiates do it as
well and also I think some grasses.
I am sure I have heard in the case of the Sorrel that there are no
pollinators for the flowers in the UK so this strategy might be a "backup
strategy" if no pollinating insect is available.
The same lack of pollinators occurs with the Bee Orchid here - but luckily
they have not given up flowering properly!
