Slender riccia and purple-fringed riccia are small leaf-like plants that are found floating on still water, often with duckweeds (Lemna sp., Spirodela sp.) The adventitious branches develop from the ventral surface of the thallus in species like Riccia fluitans. This initial enlarges, becomes papillate and first divides transversely into a basal cell and an outer cell (Fig. It is called octant stage (Fig. E) and do not undergo fruiting (Fig. But Riccia Fluitans is one species from Riccia that can grow in water.

In the apical region they project forward and. and watermeal (Wolffia spp.). Each of the three peripheral initials divides by an anticlinal vertical division forming two cells. It absorbs water, swells up and comes out of the archegonial mouth by pushing the cover cells apart. 15 K-M). In smooth-walled rhizoids both the inner and outer wall layers are fully stretched while in tuberculated rhizoids the inner wall layer modifies into peg-like or plate-like in growth which projects into the cell lumen (Fig. 11) or eight epidermal cells (e.g., R. vesiculosa). 3) Used as a foreground carpet in aqua scaping.
