They are both vascular, but gnetophytes produce flowers and fruit, and ginkgos do not.

Their xylem tissue consist of both tracheids and vessel elements.

Gnetophyta show a number of flowering characteristic.

Ginkgophyta is also a vascular seed plant but it has motile sperm. They are characterized by trees with distinct fan-shaped leaves. They have secondary xylem system.
