1.【植】(蒴)内层;药室内壁
1.the inner tissue of the spore-producing capsule of a moss
2.the tissue of the inner wall of an anther in a flower
1.The anther wall layers consist of the epidermis , the one layered endothecium, two middle layers and the tapetum of one layer.
花药壁之构成，含表皮层、一层内壁层、二层中间层和一层营养层。
2.The anther was found to be 4-sporangiate. The anther wall includes 4 layers: epiderm , endothecium, middle layer and secretory tapetum.
结果表明：山韭花药具4个药室，花药壁由表皮、药室内壁、中层和绒毡层4层细胞组成，属分泌型绒毡层。
3.Cells of epidermis, middle layers, and endothecium still highly vacuolized, tapetal cells containing small irregular lipid droplets (arrow);
示表皮、药室内壁和中层细胞质没有增加，绒毡层细胞含脂类颗粒（箭号）；
4.Only endothecium and remnants of the epidermis are preserved in the anther wall
花药成熟时，仅剩纤维层和表皮残余
