  • Abstract This study used scanning electron microscope to observe, record and compare 28 native gymnosperm species leaf epidermis morphology in Taiwan. Seven common cultivated alien gymnosperms, Calocedrus macrolepis, Juniperus chinensis, Pinus thunbergii, Pinus elliottii, Pinus luchuensis, Agathis dammara and Cryptomeria japonica were also included in observation and comparision as their leaves are very similar to native species. The characters observed included stomatomal distribution, stomatal line number, cuticulization degree, cell shape and arrangement, wall ornamentation, peripheral wall morphology, cuticular nails presence and silicon crystal distribution. The result showed that micromorphological characteristics of leaf epidermis are very useful in the identification of Taiwan gymnosperm family, genera and species. Two morphological similar and often confused Taiwan gymnosperm species pairs, Pinus morrisonicola and Pinus mastersiana, Pinus taiwanensis and Pinus massoniana, can be diferentiated with their very distinct leaf micromorphology.
