Barclaya

Vegetative characteristics Its species are perennial, rhizomatous herbs has an entire margin. The gynoecium consists of 7–12 fused carpels bears globose, echinate seeds. Cytology The diploid chromosome count is 2n = 36. ==Taxonomy==

The genus Barclaya Wall. was first published by Nathaniel Wallich in 1827 Species 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. ==Habitat==

Within tropical rainforests, Barclaya develops alongside streams or at their fringes. The escalating deforestation across Southeast Asia is causing the habitats to become clouded, endangering Barclaya. ==Conservation==

The IUCN conservation status of Barclaya longifolia is least concern (LC). The IUCN conservation status of Barclaya motleyi is data deficient (DD). ==Use==

In Laos, Barclaya longifolia is used for its edible leaves. ==Cultivation==

Barclaya longifolia is a popular aquarium plant. Under high light conditions the attractive, upright foliage displays green colouration. Under lower light conditions brownish foliage is produced. It easily sets seed in cultivation, if pollen is deposited on the stigma. ==References==
