Although these data have helped resolve the phylogeny of numerous clades (e.g., green algae, angiosperms, and gymnosperms), their utility for inferring relationships across all green plants is uncertain.

Relationship between mean leaf water potential at stomatal closure, and at 50% loss of leaf hydraulic conductivity in angiosperms (circles) and pteridophytes (triangles). They have got seeds in them that are surrounded inside the ovary. There are about eleven thousand different species of pteridophytes, making them the most diverse land plants after the flowering plants (angiosperms). 3.The venation in Ginkgo is dichotomous as in pteridophytes.
