Origin of a land flora: A theory based upon the facts of ...
In both cases a prevalence of a cylindrical protostelic state, with comparatively
slight disturbance of the axial system on departure of the leaf-traces, would be
expected if the shoot were primitively strobiloid. Further, the leaf-trace would be ...
Frederick Orpen Bower, 1908
But hitherto the anatomical conditions have not materially helped this comparison
, for in the mature state both Matonia and Dipteris have advanced solenosteles,
while Gleichenia shows in most of its species a protostelic state. It is here that ...

Botany For Degree Pteridophyta
This step led to many important changes in the protostelic organisation and gave
rise, on further elaboration, to complicated stelar types. The origin of pith has
been explained variously by various authors. Two theories have been put forth to
...
To take an analogous case ; an apparently protostelic structure is known to have
arisen in certain cases (e.g. water-plants) by reduction, yet no one doubts that in
other groups the protostele is really primitive. The author's treatment of the ...

The natural systematic of plants in the light of the present ...
Most of the true Psilophytineae are provided with cylindrical protostelic strands (
Rhyniales). In the genus of Psilophyton the same kind of stele may (be found and
in the rather very advanced Asteroxylon we see in the thinner ramifications also ...

Protostelic and homosporous. Sporangia are terminal or lateral on naked
branches. Sporophytes are rootless, with dichotomously branched rhizomes and
aerial branches. Leaf-like lateral appendages. Protostelic, homosporous. It
includes ...
Many species have stems that are protostelic in the first-formed portion and
siphonostelic in later-formed portions. Matonia pectinata R. Br. affords the best
example of this recapitulation. Here, as development progresses, there is a
transition ...

Paleobotany and the Evolution of Plants
From this description we can visualize the vascular supply of a mature Psaronius
stem as comprising a series of inverted cones fitting inside of the one below,
each being protostelic at the base and giving rise to a siphonostele dissected by
...

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 ...

I. GleIchen1a, Smith. 1793. 79 species. i. Sub-genus Dicranopteris, Bernh. 1806.
Includes probably the most primitive types, as shown by their large output of
spores per sporangium, and of spermatocytes perantheridium. Protostelic axis.
