The sclerenchymatous hypodermis aids in decreasing water loss from the leaf because of the thickness of the cell walls and the reduction in airspaces.

On the other hand, characters such as the hypoderm and sclerenchymatous fibers in the mesophyll of the foliage (leaves) (METCALFE; CHALK, 1957) were registered for seedling leaves of Serjania communis.
In large VBs, thick sclerenchymatous strands are present on the upper and lower surface, while sclerenchymatous girders are absent.
Seed coat shows 2-3 layers of thin-walled cells which are externally covered by a thin cuticle and which are internally followed by thick-walled polygonal sclerenchymatous cells.

Microscopical characters Seed powder is brown, sclerenchymatous cells of testa parenchyma cells, and oil globules are present.
Plant cell walls strengthened by deposition of macromolecules such as cellulose, lignin, suberin, and cellose together with sclerenchymatous fibers make a plant resistant to mechanical injury as well as to the tearing action of mandibles or the penetration of piercing-sucking mouthparts (Schoonhoven et al.
This implies that the composite of the non-fibrous tissues namely, vessels, axial parenchyma and ray in these species substantially outweigh the sclerenchymatous fibres, which are more preferable in any pulp producing species.
