Botany for Degree Students Part-III: Bryophyta
These are the cortex or the hyalodermis, the hadrome (prosenchymatous region)
and the medulla (axial cylinder). The cortex or hyalodermis forms the outermost
region of the stem. It varies in thickness. In young stems and branches it is only ...

IV type : Stem differentiated into epidermis, cortex, leptome and hadrome. N type :
Cells of the hadrome smaller than (N type), or as large as (M type) those of the
leptome. R type : Cell walls of the hadrome by far the thinnest (R type). Q type ...

Physiological plant anatomy
In the absorbing roots, on the contrary, which grow vertically downwards and
finally enter the soil, the width of the central cylinder is equal to one-half of the
total diameter, while the ordinary hadrome- and Icptome-strands are
supplemented by ...

A Textbook of Botany for Colleges and Universities: Ecology
In stems the hadrome generally is within the leptome. In dicotyls the mestome
strands are arranged in a broken cylinder (fig. 541), which later may become a
complete cylinder through cambium activity, while in monocotyls the bundles are
...

No endodermis is differentiated, and the stele shows a continuous zone of
leptome, here and there interspersed with cells containing single, rhombic
crystals; the cambium is well represented, and in the hadrome the porous vessels
are ...

The position of the proto-hadrome is variable, since it is not unusual to observe
some of the vessels bordering on endodermis, having thus broken through the
pericambium, a structure not uncommon in grasses and sedges. The normal ...

The appearance of the stele is now suggestive of a tetrarch structure and is as
follows: In a plane at right angles to the primary hadrome plate lie the two
leptome bundles, between which and the hadrome plate the primary cambium
lies.
