Re: Aquatic Orchid

Dear Hanna,

According to COOK (1990), there are no true aquatic Orchidaceae. Some
species of Spiranthes can tolerate short periods of flooding, and S. cernua
is sold as an aquarium plant, but "so are many other non-aquatics such as
date palm seedlings". Other genus can be found in mats of floating
vegetation, but not possess any adaptations to aquatic life.
Sincerely yours,
