Plant Diversity(Nonvascular Plants)

Non-vascular plants have no roots, stems, or leaves, since each of these structures is defined as containing vascular tissue. The lobes (rounded parts) of the liverwort may look like leaves, but they are not true leaves because they have no xylem or phloem.

Some uses of nonvascular plants include

Sphagnum (bog or peat moss) has tremendous ability to absorb water and is important in gardening.
Sphagnum does nat decay in some acidic bogs; the dried peat can be used as fuel.
The uses for intact moss are principally in the florist trade and for home decoration. Decaying moss in the genus Sphagnum is also the major component of peat (as mentioned above), which is "mined" for use as a fuel, as a horticultural soil additive, and in smoking malt in the production of Scotch whisky.

In rural UK, Fontinalis antipyretica was traditionally used to extinguish fires as it could be found in substantial quantities in slow-moving rivers and the moss retained large volumes of water which helped extinguish the flames. This historical use is reflected in its specific Latin/Greek name, the approximate meaning of which is "against fire".

In World War I, Sphagnum mosses were used as first-aid dressings on soldiers' wounds, as these mosses are highly absorbent and have mild antibacterial properties. Some early people used it as a diaper due to its high absorbency.
