The endodermis in Pinus, Picea and many other genera is usually a well-defined layer of cells enclosing the vascular bundles, and separated from them by a tissue consisting in part of ordinary parenchyma and to some extent of isodiametric tracheids; but this tissue, usually spoken of as the pericycle, is in direct continuity with other stem-tissues as well as the pericycle.

They are more or less angular, and while elongated transversely at first, become nearly isodiametric as the pileus becomes fully expanded, passing from an elongated form to rectangular, or sinuous in outline, the margin more or less upturned, especially in age, when they begin to loosen and "peel" from the surface of the cap.

When To Use

What does isodiametric mean?

Isodiametric describes having the same diameters or axes.When two objects have the same diameter, they are isodiametric—that is, they have the same circular width. Two isodiametric objects may look alike, or they may look different and be different shapes. For example, two ovals could be isodiametric at their horizontal diameter but have completely different vertical diameters.Isodiametric is especially used in geometry and any field that involves geometric design, such as architecture, engineering, or design. In botany, isodiametric is used to describe a plant’s parenchyma cells, most of which are unspecialized. This is why they are isodiametric, or of similar size and shape.In geology and crystallography, isodiametric describes crystals with two or three equal horizontal axes and an additional, unequal axis at right angles.Example: The two celestial bodies are isodiametric, leading us to believe they may be similar in other ways as well.
