Summary

[edit]
Description

cross section: Syringa leaf magnification: 400x

The upper and lower epidermis are uniseriate with a thin waxy cuticle. Stomata are abundant on the lower or abaxial surface and may occasionally be seen on the upper or adaxial surface as well. Small mushroom shaped peltate trichomes are also present in the lower epidermis. These secretory trichomes have short stalks, appearing to sink into the epidermis.

A large upper palisade mesophyll is composed of two layers of elongated, densely packed photosynthetic parenchyma interrupted by an occasional substomatal air spaces. A smaller lower spongy mesophyll is composed of aerenchyma; loosely arranged photosynthetic parenchyma with abundant air spaces.
