Major Events in the History of Life
They considered that the presence of erect, persistent, differentiated tissue-
containing, un- branched sporophyte axes is a character of the moss-
tracheophyte lineage. Inasmuch as only tracheophytes developed branched
axes and multiple ...

Phanerozoic Diversity Patterns: Profiles in Macroevolution
Three of these four phases of tracheophyte evolution are associated with
significant increases in the total species numbers of land plants. The first
occurred within a 60 Myr period between the appearance of the first vascular
plants and the ...

This currently leaves us with a considerable phylogenetic gap between the
bryophytes and the seed plants for mitochondrial genome sequences of early
branching (i.e., non-seed) tracheophyte lineages (Fig. 1.1). Fig. 1.1 (continued)

The Evolutionary Biology of Plants
If so, then the hydroids of modern mosses more likely reflect the ancestral
condition of the moss- tracheophyte clade rather than highly reduced tracheids.
This hypothesis also resolves the developmental differences between the moss
and ...

Seedling Ecology and Evolution
Some tracheophyte embryos also develop a structure called the foot (e.g.
Lycopodium, Equisetum, and Botrychium), which typically occupies the same
position as that of the bryophyte foot relative to the apical--basal embryo axis. It is
not clear ...

A seedless-tracheophyte group characterized by having lateral sporangia and no
leaves or roots (Campbell 1996, 557, illustration; Strickberger 2000, 304).
Comment: There are about 10–13 living psilophyte species (Campbell 1996, 550

Planation in lateral branching systems occurred in some still younger taxa, while
arborescence and true leaves had evolved in many tracheophyte lineages by the
end of the Devonian. It is not logical for us to deduce a cause-effect relation ...
