"Barclaya" is a genus of 3 - 4 species of flowering plants usually included in the family Nymphaeaceae but sometimes given their own family status as Barclayaceae on the basis of an extended perianth tube (combined sepals and petals) arising from the top of the ovary and by stamens that are joined basally. "Barclaya" are aquatic plants native to tropical Asia.

The genus was named in honour of the English gardener and plant collector G. W. Barclay.

ynonym

"Hydrostemma" is a name that takes precedence over the name "Barclaya", on account of having been published 6 months earlier. However, the name "Barclaya", being much better known than "Hydrostemma", has been "conserved" and "Hydrostemma" is therefore a synonym of "Barclaya". [W.E. Crusio and J. Bogner.

Taxonomy

Recent morphological and genetic studies support the view that "Barclaya" should be retained in the family Nymphaeaceae.
