inophyllous-
Leaves tufted ; stipes 15 - 30 cm long, densely scaly at base, glabrous above ; sterile lamina about 60 cm long and 20 cm wide, simply pinnate ; pinnae numerous, alternate or subopposite, linear - lanceolate, the largest about 12 cm long and 1 cm wide, base cordate, apex acuminate, margin finely toothed ; veins close, forking once or twice and forming areoles near the midrib ; fertile lamina similar to sterile ones, but somewhat reduced, about 8 cm long and 0. 4 cm wide, lower surface almost entirely covered with sporangia
葉簇生；葉柄長15 - 30厘米，基部密被鱗片，向上近光滑；不育葉片長約60厘米，寬20厘米，一回羽狀；羽片多數，互生或近對生，線狀披針形，最長者長達12厘米，寬約1厘米，頂端長漸尖，基部心形，邊緣有細密鋸齒；葉脈1 - 2次分叉，近中脈形成網眼；能育葉與不育葉相似，但較小，長約8厘米，寬約0 . 4厘米，下部滿布孢子囊。We use bezier curves to describe the shape of leaf midrib and embed the image of leaf into the space of local frames along the midrib curve
植物葉面的造型採用bezier參數曲線描述葉子中脈的形狀，然後將葉子的紋理圖象嵌入到葉脈曲線的局部標架中。As for the leaves, we use bezier curves to describe shape of leaf midrib. the texture image of leaf is embedded into the space of local frames along the midrib curve
對于葉片的生成，本文採用bezier參數曲線描述葉子中脈的形狀，把樹葉或草葉構成的星形結構紋理圖象嵌入到葉脈參數曲線的局部標架中來實現。
