University Botany I : (Algae, Fungi, Bryophyta And Pteridophyta)
A medullated protostele is known as siphonostele. This type has evolved from
protostele, and it is advanced over the protostele. In siphonostele the vascular
tissues are arranged in the form of a hollow cylinders around the central pith.

5.3.2 Siphonostele In siphonostele, the pith is present in the centre of stele or in
other words, the protostele with pith is called siphonostele. It is also called
medullated protostele. The origin of pith may be intrastelar or extrastelar.

It is also extremely difficult to interpret certain types of siphonostele on the basis
of an invasion of cortical tissue. For example, it is practically impossible to
visualize the type of cortical invasion that would produce polycyclic siphonosteles
