The vascular cambium usually consist of two types of cells:
  • Fusiform initials (tall cells, axially oriented)
  • Ray initials (almost isodiametric cells - smaller and round to angular in shape)

Gymnosperm

Gymnosperm is a group of spermatophyte seed-bearing plants with ovules on scales, which are usually arranged in cone-like structures.
