• Mosses don’t have a vascular system so they
must live close to the ground, and in moist
areas.
– Forms a mat to keep the moisture in.

• The growth, death, and decay of mosses
produces more humus, and soon there is
enough to support the growth of grasses.

• Peat Moss / Sphagnum: The partially
decomposed remains of various mosses.
– Retains water, adds to the acidity of the soil pH.

Bog: An area of wet, spongy ground consisting mainly of
decayed or decaying peat moss (sphagnum)
• The acidic soil of peat bogs has preserved
bodies and artifacts.

New Area of Focus: Seedless Vascular Plants.
Copyright © 2010 Ryan P. Murphy
• The seedless non-vascular plants consist
of the following divisions.
– Psilophyta
– Lycophyta
– Sphenophyta
– Pterophyta (Ferns)
Copyright © 2010 Ryan P. Murphy
• Psilophyta: No leaves or roots, just stems.
Copyright © 2010 Ryan P. Murphy
• Psilophyta species were one of the earliest
terrestrial plants during the Devonian
Period.

• Lycophyta: They have root like structures
called rhizomes, and spores are clustered
in a cone-like strobilus.

• Sphenophyta: Horsetails or scouring
rushes. The plant has a scaly stem, it has
roots.
Copyright © 2010 Ryan P. Murphy
• They reproduce with spores located at the
top of the horsetail.

division in the plant world consisting of
20,000 different species.

Ferns: Flowerless and seedless vascular plant, having true roots from a rhizome, and fronds that uncurl upwards; and reproduces with bisexual spores.

• How Many? Answer… Zero
• Ferns have fronds, not leaves.
