Abstract
An electron microscope has been used to investigate the ultrastructure of leaf cells in Deschampsia antarctica Desv. (Poaceae). The leaf anatomy exhibits features typical of xerophytes. New ultrastructural features were found in mesophyll cells. Chloroplasts in mesophyll cells of D. antarctica leaves form small vesicles and pockets. The outer chloroplast membrane forms vesicles, and pockets are invaginations of both membranes. The invaginations contain small vesicles, mitochondria, or lipid droplets. The mitochondria or peroxisomes adhere very tightly to the chloroplasts.
