The discovery of viral metagenomes with genes coding for energy metabolism and protein synthesis fueled the debate about whether viruses belong in the tree of life; the presence of these genes suggested.

    Before the advent of modern molecular studies, the relationship of this group to other living and fossil plants was considered problematic; because of their unclear relationships, the rank botanists have assigned to the horsetails varies from order to division. Traditionally, all of the spore producing vascular plants were informally denominated the pteridophytes, rendering the term synonymous with ferns and fern allies; this can be confusing because members of the division Pteridophyta were denominated pteridophytes.

    Thallophytes have a hidden reproductive system and hence they are also bodies (thalli), as opposed to cormophytes (Cormophyta) with roots and stems.
