It is measured the shape and venation parameters of sun and shade leaves on short- shoots and long- shoots of modern Ginkgo leaves in Nanjing，China． The venation density of these leaves are 14. 78 ± 2. 44 cm， 16. 05 ±2. 57 cm and 15. 31 ±2. 34 cm，respectively for the sun leaves on long- shoots，sun and shade leaves on short- shoots． The venation index of these leaves are 0. 090 ±0. 026，0. 098 ±0. 037 and 0. 091 ±0. 027，respec- tively． This indicates that the venation parameters are not influenced by whether they are born on short- shoots or long- shoots，and by where they live under sun or shade．
