A number of bundles were made up for them to carry.
These bundles cotyledon.
The in Stems. bundles of plants which form cambium are, on the contrary, called open.

In the very frequent cases where the bundles have considerable individuality, the fibrous pericyclic cap very clearly has a common origin from the same strand of tissue as the vascular elements themselves.
