Barclaya
Encyclopedia
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.
and Hydrostemma is therefore a synonym of Barclaya.
