This paper is a study of the ultrastructual differences of the leaves of K.humilis and K.pygmaea from height gradient of 3260 to 4050 metres. It is discovered that the chloroplast and mitochondrium cell metamorphosis increases with the height gradient. However, the content of endoplasm reticulum and golgiosome decreases and their structures become simple.
