<jats:p>
We have constructed a phylogenic tree for green plants by comparing 5S rRNA sequences. The tree suggests that the emergence of most of the uni- and multicellular green algae such as
<jats:italic>Chlamydomonas, Spirogyra, Ulva</jats:italic>
, and
<jats:italic>Chlorella</jats:italic>
occurred in the early stage of green plant evolution. The branching point of
<jats:italic>Nitella</jats:italic>
is a little earlier than that of land plants and much later than that of the above green algae, supporting the view that
<jats:italic>Nitella</jats:italic>
-like green algae may be the direct precursor to land plants. The Bryophyta and the Pteridophyta separated from each other after emergence of the Spermatophyta. The result is consistent with the view that the Bryophyta evolved from ferns by degeneration. In the Pteridophyta,
<jats:italic>Psilotum</jats:italic>
(whisk fern) separated first, and a little later
<jats:italic>Lycopodium</jats:italic>
(club moss) separated from the ancestor common to
<jats:italic>Equisetum</jats:italic>
(horsetail) and
<jats:italic>Dryopteris</jats:italic>
(fern). This order is in accordance with the classical view. During the Spermatophyta evolution, the gymnosperms (
<jats:italic>Cycas, Ginkgo</jats:italic>
, and
<jats:italic>Metasequoia</jats:italic>
have been studied here) and the angiosperms (flowering plants) separated, and this was followed by the separation of
<jats:italic>Metasequoia</jats:italic>
and
<jats:italic>Cycas</jats:italic>
(cycad)/
<jats:italic>Ginkgo</jats:italic>
(maidenhair tree) on one branch and various flowering plants on the other.
