Barclaya
Barclaya is a genus of six species of flowering plants of the family Nymphaeaceae. Barclaya are aquatic plants native to tropical Asia. The genus was named in honour of the American-born English brewer and patron of science Robert Barclay. Synonym Though Hydrostemma is a name that is older than the name Barclaya, having been published 6 months earlier, the name Barclaya has been "conserved" as it was deemed being much better known than Hydrostemma. Taxonomy Rejected classification The separate family Barclayaceae H.L.Li was published in 1955. It has been believed to be separate, due to the extended perianth tube (combined sepals and petals) arising from the top of the ovary and by stamens that are joined basally. However, morphological and genetic studies support the position of Barclaya in the family Nymphaeaceae. A separate order Barclayales Doweld was proposed in 2001. The accepted placement of Barclaya is within the family Nymphaeaceae of the order Nymphaeales. Description Plants grow from egg-shaped tubers that produce short runners and a basal rosette of leaves. All leaves are submerged. Cytology The chromosome count of Barclaya longifolia is n=17. Species Habitat Within tropical rainforests, Barclaya develops alongside streams or at their fringes.
