There isn't one single scientific name for all vascular plants. Instead, vascular plants make up a large group, often referred to as Tracheophytes or Tracheophyta.

Here's why:

* Scientific names are specific to individual species. For example, the scientific name for a common garden rose is *Rosa × damascena*.

* Vascular plants are a broad category that includes ferns, club mosses, horsetails, and seed plants (which are further divided into gymnosperms and angiosperms).

Therefore, "Tracheophytes" or "Tracheophyta" are considered the scientific names for the group of vascular plants.
