This is faulty information. Orchids can open and close stomata

Subject: [OGD] Question about stomata
I recently purchased Lance Birk's new Paphiopedilum Grower's Manual. In his
discussion about watering and watering technique he makes the statement
that
Orchids have "fixed stomata", and they remain open all the time regardless
of
environmental conditions. Never having heard this before, I am curious as
to its
veracity. Does anyone in the group have knowledge about this? I know that
some orchids are CAM plants, and thought one of the reasons for practicing
this
kind of carbon fixing was to keep stomata closed during the day and thus
control water loss.
Thanks
