The Podostemaceae are a plant family in the order of the Malpighia-like (Malpighiales) within the flowering plants (Magnoliopsida). The kormus- like shape with often strongly receded plant parts is an adaptation to their location on stones in flowing waters. Many species are reminiscent of liverworts in their habitus and can only be clearly recognized as flowering plants for the layperson when they are in bloom.
description
They are annual or perennial herbaceous plants . It is the most species-rich family of flowering plants (Magnoliopsida) with only submerged, i.e. submerged, aquatic plants that usually thrive in fast-flowing river sections and even in waterfalls. The mostly flattened, thalloid or thread-like roots anchor the plants to stones or wood. The leaves , arranged in two rows on the stems, are scattered or scale-shaped, with a flat leaf base and smooth or divided leaf margin.
The flowers can be solitary by a spathaähnlichen bract be wrapped. The hermaphroditic flowers are radial symmetry or zygomorphic . The two to five bracts are free to more or less fused. There are one to four stamens with free or partially overgrown stamens. Two to three pistils have become a top permanent ovary grown, many ovules includes a central placentation. There are two or three free pens available.
Septicidal capsule fruits with many seeds are formed. The tiny seeds have no endosperm .
Systematics and distribution
The Podostemaceae family has a pantropical distribution overall, but many of the species and even genera are only native to narrowly defined areas. In the Neotropic there are about 21 genera with about 135 species.
The Podostemaceae family was first published in 1816 by Louis Claude Marie Richard in Karl Sigismund Kunth : Nova Genera et Species Plantarum , 4th edition, 1, p. 246 under the name "Podostemeae" and another publication by him took place in Aphor. Bot. , 125, 19, 1822. The type genus is Podostemum Michx. Synonyms are for Podostemaceae Rich. ex Kunth are: Marathraceae Dumort. , Philocrenaceae Bong. , Tristichaceae Willis .
