siphonostele  

One of 2 basic morphologies of stele, the other being protostele. Siphonosteles are the more highly developed form, being characterized by a cylinder of xylem and phloem surrounding a pith. ...

solenostele  

The most highly developed type of protostele; it is found in Selaginella, often arranged as a polystele. In ferns, and occasionally in Selaginella, the solenostele is amphiphloic, differing from ...

...The most highly developed type of protostele ; it is found in Selaginella , often arranged as a polystele . In ferns, and occasionally in Selaginella , the solenostele is amphiphloic, differing from amphiphloic siphonostele in the absence of a pith , instead encompassing endodermal cells ( see endodermis ). In ferns, leaf gaps may occur, in which case the solenostele may become a reticulate network and, therefore, be termed a dictyostele . Compare actinostele ; haplostele ; hypophloic haplostele...
