Lycopodium clavatum Lycopodium selago Selaginella lepidophylla

Lycophyta (lycopods)

  • free-living sporophyte and gametophytes
  • leaves and roots different from other land plants
  • in the geologic past (ca 300 MYA), the lycopods were the dominant floral elements with large, expansive swamp-forests of lycopods. Much of the coal and oil found today were formed from the extensive growth of these plants
