The shapes of leaf epidermal cells of these three families are usually or ; the patterns of anticlinal walls are, arched or. The stomatal apparatuses, only present on the abaxial epidermis for all sampled species ( except for Cardiospermum halicacabum and Eurycorymbus cavaleriei), can be assigned into six types. The type, occurring in 16 species ( Allophylus caudate, Handeliodendron bodinieri, and Delavaya toxocarpa, etc.) is very common; the type, occurring in 11 species ( Amesiodendron chinense, Aesculus chinensis, Dipteronia sinensis, etc.), and the cyclocytic type, occurring in 6 species ( Dimocarpus longan, Litchi chinensis, Nephelium chryseum) are comparatively : : Author for correspondence ; Email: nhxia@ scib. ac. cn : 2007 11 15, 2008 01 21 : (1970 ),,,
406 30 common; whereas the other three types can be considered diagnostic of several genera, such as hemiparacytic type for Aphania oligophylla, Pometia tomentosa and Xerospermum bonii, Harpullia cupaniodes, staurocytic type mainly for Pavieasia kwangsiensis, and anisocytic type only for Cardiospermum halicacabum. Under SEM the cuticular layer of the leaf epidermis is striated, scaly or granular; the inner margin of outer stomatal rim of most species of these three families is undulate. The close relationships among Sapindaceae, Hippocastanaceae and Aceraceae are supported by the evidence from leaf epidermis.
