| Anatomical features of leaves of 18 mangrove species and 2 none mangrove species belonging to Rhizophoraceae, Combretaceae, Sonneratiaceae, Myrsinaceae, Verbenaceae and Acanthaceae were surveyed and analyzed. The morphologicalfeatures of structure and quantity of leaves were described and stated thoroughly by means of optical microscopy, scanning electronic microscopy and laser scanning confocal microscopy. These results were used for the identification of species, related to systematic position and correlated with ecological adaptation to intertidal habitats. Correlation of features of structure of leaves of Kandelia candel, Avicennia marina, Aegiceras corniculatum and soil physical and chemical properties or latitude were studied. Relationship between soil physical and chemical properties or latitude and quantitative features of leaves were analyzed by means of statistical methods. This study will provide important information on ecological function of mangroves, identification of species, habitat, degree on economy of evolution, transplant and protection of swamp.1.Features of form, anatomy and structural quantity of leaves of 7 mangrove species in Fujian of China were studied for the first time. The leaves of mangrove species had common features of structure with lesser epidermis cell, hypodermis structure, settle of stomata, abundant palisade tissue,vascular bundle in midrib and dannin. Stomata is found to be one of the approach that mangrove vents salinity, and its mechanisms need further discussion.2.Features of anatomy and structural quantity of leaves of 7 mangrove species and 2 other plants of Rhizophoraceae in China were studied for the first time. The results showed:â‘ Features of structure of leaves of mangrove species were different with those of other plants significantly , which was mainly related to acclimatization.;â‘¡There are lenticel hydathode in the structure of leaves of Rhizophora stylosa and Rhizophora apiculata, and cork nubble in the structure of...
