Paleobotany: The Biology and Evolution of Fossil Plants
In a single cross section, a eustele may look like a dictyostele, in that the cylinder
of vascular tissue appears dissected. The sympodial strands in seed plants,
however, are discrete and continue throughout the stem (FIG. 7.43C, D). The
ground ...

Paleobotany and the Evolution of Plants
The evolution of the gymnosperm eustele Most of the evidence supports an origin
of the Calamopityceae, and possibly the Lyginopteridaceae, from the
Aneurophytales. These two families have evolved eusteles, the basic
arrangement of the ...

architectures in plants is considered to be related to, and correlated with, the
evolution of leaf and branch size and complexity, and to hormonal control of
differentiation ...

Botany For Degree Gymnosperm (M.E.)
Two views are prevalent regarding the origin of the eustele from the primitive
protostele : 1. Jeffrey (1899, 1902, 1917) suggested that from the basic protostelic
condition the first step in stelar evolution was the appearance of a pith in the
centre ...

New Organic Architecture: The Breaking Wave
Protostele with mixed pith and eustele. This stelar type is characterized by a ring
of discrete or longitudinally interconnected sym- podial strands at the periphery of
a parenchymatous pith or of a mixed pith with scattered tracheids; the primary ...

Annual Plant Reviews, The Evolution of Plant Form
These may rep— resent leaf primordia whose development was arrested before
production of pinnae. Inside the stem, the most conspicuous innovation of living
seed plants is the eustele, with a ring of primary vascular bundles around a pith.

The Evolution of Plants
Eustele A third stele type, termed the eustele (Figure 4.7c), first emerged in the
fossil record at ~390 Ma. This stele appears to be the most complex of the three
structures in that it was composed of distinct strands of phloem and xylem, ...

Botany For Degree Pteridophyta
Namboodri and Beck (1968) and Beck (1970) have put forth an explanation that
the eustele in gymnosperms is not derived from filicean type of siphonostele nor
are there any filicean type of leaf gaps. These authors studied the stelar ...
