Tracheophyte, a member of the largest and most varied group of plants. Tracheophytes are also called vascular plants, because they have vascular, or conductive, tissues. These tissues are of two kinds, xylem and phloem, and transport fluids through the plant. Tracheophytes have true roots, stems, and leaves. Most live on land, but a few (such as water lilies) are water plants. Tracheophytes include whisk ferns, club mosses, horsetails, ferns, cycads, ginkgoes, gnetophytes, conifers, and flowering plants.

Tracheophytes make up the subkingdom Tracheophyta. Whisk ferns make up the division Psilophyta; club mosses, the division Lycophyta; horsetails, the division Sphenophyta; ferns, the division Pterophyta; cycads, the division Cycadophyta; ginkgoes, the division Ginkgophyta; gnetophytes, the division Gnetophyta; conifers, the division Coniferophyta; and flowering plants, the division Anthophyta.
