1、endothecium anther───内囊花药
1、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
2、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。
3、Secondly, there was a little of collenchyma whose texture was tight in smooth type's endothecium of phellem;───另外，光皮型杜仲在栓内层分布有较少的，质地紧密的石细胞群；
4、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）；
5、Recent research shows that the vascular endothecium has played a vital role in regulating the cordis circulation and stabilizing the milieu interne.───近年来的研究证实，血管内皮在调节心脏循环功能和稳定内环境中起到重要作用。
6、At anthesis, the mature anther wall included epidermis and some layers of parenchymal cells and several layers of endothecium cells with an evidently thickened radial wall.───开花时，花药壁由表皮和几层薄壁细胞以及径向壁纤维加厚的变形细胞组成。
7、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。
1、The development of anther wall follows the dicotyledonous type, composed of four layers, respectively epidermis, endothecium, middle layer and tapetum.
2、The main results are as follows: (1) Anther wall comprises epidermis, fibrous endothecium, one middle layer and glandular tapetum with two-nucleate cells.
3、The anther wall of Setaria glauca consists of four layers: epidermis, endothecium , mid-dle layer and tapetum.
4、Fibrous thickenings are formed in the cells of the endothecium. In staminate flowers, the septum separating anther locules was cleaved and the stomium was degenerated to release the pollen grains.
5、Recent research shows that the vascular endothecium has played a vital role in regulating the cordis circulation and stabilizing the milieu interne.
6、The anther was found to be 4-sporangiate. The anther wall includes 4 layers: epiderm, endothecium, middle layer and secretory tapetum.
