Riccia Fluitans, also known as Crystalwort, is a floating aquatic plant made popular by well known and respected nature aquarium master, Takashi Amano. Due to prolonged dry summer or towards the end of growing season the whole thallus in some species (e.g., Riccia discolor) dries and gets destroyed except the growing point. Primary stalk cells form the stalk of the antheridium. The ventral surface of thallus bears many scales and rhizoids. Sex organs develop in acropetal succession (i.e., mature sex organs are present at the posterior end, the young ones towards the apex of the thallus). However, Srivastava (1964) recorded 29 species from different parts of India. Subordinate Taxa. 16 C).

He was the first individual to utilize this delicate plant as an epiphyte by attaching it to hardscape material such as stones and aquarium driftwood. Riccia is a well-recognized floating plant, made popular by the renowned aquascaper Takashi Amano. Curiosity of this plant: it is at the same time a floating plant, moss and fern! 2, 3). These plants are small and thalloid, that is not differentiated into root, stem and leaf. A periclinal division is laid down in both the tiers of four cells and there is the formation of eight outer sterile jacket initials and 8 inner primary androgonial cells (Fig. Rooted aquatic plants will filter the water to a lesser extent, but will also help oxygenate the water. Image of nature, water, clay - 91735131 Riccia … 17 J, M). The cell walls form the semifluid content of the antheridium during the metamoiphosis. Then break up all the clumps of matted riccia into seperate plantlets. This plant serves as an ideal refuge for the young fry. There is no special method of dispersal, Spores remain inside the thallus for one year or so and dispese after the death and decay of the calyptra and surrounding tissue. 1, 3).

Ricciaceae. Thallus is 5-7 mm long and 1.2 mm broad in all the terrestrial species. 7). Fertilization ends the gametophytic phase. According to Pagan (1932), some of the spore mother cells in Riccia crystallina fail to produce spores and form abortive nutritive cells called nurse cells. Since Riccia flutians is a rapidly growing aquatic plant and hence needs frequent pruning otherwise, the parts that do not receive adequate sunlight might wither off. 21 E). 17 B). In the mature archegonium the venter canal cell and neck canal cells disintegrate and form a mucilaginous mass. Riccia Fluitans, also known as Crystalwort, is a floating aquatic plant made popular by well known and respected nature aquarium master, Takashi Amano. In this way the primary axial cell gets surrounded by six cells (Fig. Rhizoids are unicellular and un-branched. A single-layered sterile jacket encloses the mass of androcytes which metamorphoses into antherozoids. 18 M; 19). A mature sporogonium is represented only by spherical spore sac or capsule. Each androcyte thus metamorphosis into an antherozoid (Fig. A few white, root-like structures sometimes appear on its underside. The colour of the scale is due to dissolution of the pigment in the cell sap. 3) Used as a foreground carpet in aqua scaping. P. F.
