THE centripetal xylem in the stem among the vascular plants is confined to the Pteridophyta and lower gymnosperms, the Pteridospermæ and the Cordaitales. The vegetative stem of Cycadales and Coniferales lacks centripetal xylem; but it occurs in a poorly developed condition in certain conservative regions like the reproductive axes and the leaf traces. In the Gnetales and the angiosperms the axial organs show exclusively the endarch condition, and the centripetal xylem is altogether absent from the primary vascular bundles.

How many types of elements together make up the xylem tissue?
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same .
