This is the measurement data for analyzed leaves for sun/shade leaf identification in two species of evergreen oaks: Quercus bambusifolia and Quercus myrsinifolia (section Cyclobalanopsis). Principal characters for distinguishing shade and sun leaves in the studied oaks were identified as leaf lamina length to width ratio (L/W), and the degree of development of venation networks. For Q. myrsinifolia, shade and sun leaves differ in tooth morphology and the ratio of toothed lamina length to overall lamina length. The main epidermal characters are ordinary cell size and anticlinal wall outlines. For both species plasticity within shade leaves exceeds that of sun leaves.
