'''''Alisma''''' is a genus of plants in the [[Alismataceae]] or water-plantain family. The genus consists of [[aquatic]] plants with [[leaves]] either floating or submerged, found in a variety of still water habitats. The [[flowers]] are [[hermaphrodite]], and are arranged in [[Inflorescence|panicles]], racemes, or umbels. ''Alisma'' flowers have six [[stamens]], numerous free [[carpels]] in a single whorl, each with 1 ovule, and subventral styles. The fruit is an [[achene]] with a short beak.
The nineteenth century [[Briton|British]] art and social critic [[John Ruskin]] believed that the particular curve of the leaf-ribs of ''Alisma'' represented a model of 'divine proportion' and helped shape his theory of [[Gothic architecture]].
