The fibrovascular bundles also contain soft-walled prosenchyma cells.
Sometimes these crystals are coarser and less needle-like, as in Fig.K. Fig. C shows a transverse section through the leaf-bearing portion of the rhizome (at a), and is rather irregular on account of the fibrovascular bundles diverging into the base of the leaves of flower-stalks.
These fibrovascular bundles consist mainly of dotted or reticulated ducts (Fig. F), but all gradations from, this to the spiroids, or even true spiral ducts (Fig. E). may be found, though the annular and spiral ducts are quite rare.
In it we see the nuclear sheath, varying in width from one to three cells, and inclosing a number of crescent-shaped fibrovascular bundles, with their convexities toward the center and their horns toward the nuclear sheath.
There are also from two to four or five free closed fibrovascular bundles in the central pith.
The larger follicles (Fig. 1164) consist of an external fibrovascular coat, connected with the surrounding stroma of the ovary by a net-work of bloodvessels; and an internal coat, which consists of several layers of nucleated cells, called the membrana granulosa.
If the fibrovascular rope is the mechanical impediment which hinders the normal growth, we may try the effect of cutting through this rope.
Woody layers of strongly developed fibrovascular strands were seen to be separated one from another only by very thin layers of parenchymatous cells.
If the fibrovascular connection of the leaf-bases were lost at the same time the stems would grow and become straight and tall.
The fibrovascular strands constitute a strong rope, which is twisted around the stem along the line on which the leaves are inserted.
