Variations of leaves


ST1 ST2
[1] leaves at Kirishima, Kyushu Island, Japan, on March 28, 2003. The leaves are extremely smaller in Kirishima than in Hokkaido. When I saw the leaves, it was hard for me to believe that those leaves are Q. mongolica var. grosseserrata. Compare to a palm. [2] a leaf in Tomakomai Experimental Forest, Hokkaido, on September 10 2009. The box is a cigarette case.
