family lycopodiaceae การใช้

• The genera of Huperziaceae are included in the family Lycopodiaceae in several classifications ( in fact older classifications included the species of " Huperzia " within " Lycopodium " ) and there is as yet no consensus as to whether Huperziaceae should be recognized as a distinct family.
• In the families Lycopodiaceae and Huperziaceae, gametophytes are subterranean and mycotrophic, deriving nutrients from symbiosis with fungi . " Isoetes " and " Selaginella ", which are heterosporous, megagametophytes develop inside the megaspores, which crack open at the trilete suture to allow the male gametes to access the egg cells in the archegonia inside.
