Definition of "tracheophyte"

By virtue of the presence and absence of vascular tissues, the tracheophytes and the bryophytes were also considered two distinctly different levels of anatomical organization. Largely for these reasons, the bryophytes and the tracheophytes are traditionally viewed as two distinct lineages, though they trace their evolutionary history back to a common ancestor.

The tracheophytes (vascular land plants) have a fossil record beginning in the Wenlock (Edwards et al. 1983).

There is a clear relationship between tracheophytes and trilete spores, but not with cryptospores.
