Botany For Degree Pteridophyta
another amphiophloic siphonostelic cylinder so that the stele becomes polycyclic.
There is a parenchymatous ring between the two concentric steles. Further
ontogenetic changes lead to the development of third siphonostelic ring around
the ...

Biology: A Search For Order In Complexity
Some of the ferns have protostelic (pro't3-ste'ITk) xylem patterns, and others have
the siphonostelic plan. In the protostelic arrangement, the tubes are in a mass,
whereas the siphonostelic pattern is cylindrical. Much like the seed plants, ...

Pteropsida and almost always among the siphonostelic Lycopsida, successive
gaps in the stele ase a considerable distance above one another. Such
siphonosteles without an overlapping of gaps are solenosteles. In the more
advanced ...

Annual Plant Reviews, The Evolution of Plant Form
The ancestral arrangement of the Vasculature is protostelic with a central xylem
core surrounded by phloem (Bower 1935; Smith 1938). Siphonostelic
Vasculature, central ground tissue surrounded by xylem and phloem, evolved
later. Early in ...

United States Geological Survey Professional Paper
Among the siphonostelic members are encountered features that indicate an
affinity with Tempskya. The section Aneimiorrhiza of Aneimia forms a natural
group of at least seven species, all having siphonostelic stems. Boodle 30 has ...

Stem is protostelic, siphonostelic or dictyostelic. Occasionally, it is polycyclic.
Rarely, there is limited secondary growth. The siphonostelic cylinder differs from
other pteridophytes (microphyllous) in having leaf gaps. Sporangia are thick or ...

ADVANCES IN BOTANICAL RESEARCH APL
This interpretation of the primary structure was based on the postulate that as the
axes aged there had been a “dediii'erentiation” of tissues to produce the
siphonostelic condition, followed by divisions in the medulla and xylem which
gave rise ...
Reginald Dawson Preston, 1963
Protopityales of Lower Carboniferous have endarch, siphonostelic condition. The
leaves of this group are not known. The diversity in steles from protostelic to
siphonostelic and mesarch to endarch conditions can be thought of as stages in
the ...
