Description
Turcha is a herb floating freely in the water. The stem is branched, covered with comb-cirrus leaves ; the stem and leaves are immersed in water; only a leafless flower arrow up to 30 centimeters high, bearing pinkish flowers located whorled, is exposed from the water; a flower sits on a long leg in the bosom of a linear covering sheet; the flower is regular, bisexual, the calyx is deeply divided, with narrow lobes; a corolla is dish-shaped about five oblong obtuse lobes, the throat of the corolla is somewhat thickened and yellow; five stamens attached to the corolla tube; the pestle is one with the upper, single-nested polyspermous ovary and with a long column. Fruit - a multi-seeded spherical capsule opening with five leaves; the seeds are small, oval. No roots . In addition to seeds, this plant propagates by buds, appearing in the autumn at the top of branches, where the leaves are underdeveloped, remaining crowded; the bud overwinters and in the spring grows into a new plant.
The number of chromosomes is 2n (20 or 22).
