- With exposure after death, the epicuticle, which is the epibiont attachment surface, has been shown to degrade.
- The thin, soft upper layer of epicuticle is also absent from the surface of C. punctata, possibly due to abrasion or exfoliation, but present on the lower surface of each fungiform structure.

- For instance, compared with those of seedlings or acclimated plantlets, leaves of in vitro-regenerated plantlets have little epicuticular wax and stoma functioning is often altered.
- There are many other documented changes in shoot morphology which take place in the droughted plant (e.g. changed stomatal differentiation, synthesis of epicuticular waxes, formation of thorns, hairs etc).
- In order to analyse the relevance of the epicuticular wax to the overall transpiration barrier, the epicuticular layer was selectively removed with gum arabic.
