The type of stomatal apparatuses is a good character to distinguish between some genera , such as hyoscyamus , anisodus , atropanthe and atropa 气孔器类型可以作为区分部分属的依据之一。
2.
The surface structure of the seeds is cerebelloid , or nearly so in anisodus and hyoscyamus pusillus , and reticulate in all the remaining genera and species . the testa cells fall into two types in terms of their shape and pattern of the cell walls . in one type the testa cells are from polygonal to suborbicular in shape , isometric , with the cell walls being nearly straight , and in the other the testa cells are irregular in shape , often not isometric , with the cell walls being variously sinuate 外种皮细胞形状和周壁式样有两大类，一类为多边形至近圆形，等径，周壁近平直，另一类为形状不规则，常不等径，周壁为各式波状：外种皮细胞周壁内侧有皱波状、瘤状、小颗粒、片状或小刺等各式附属物。
3.
In the 25 species examined , the epidermal cells fall into four types in terms of their shape and the pattern of the anticlinal wal ls . these types correlate to some extent with features of gross morphology , palynology and plant geography of the ten genera studied . features of cuticular membrane can be used to differentiate clearly the two genera physochlaina and hyoscyamus , and some species within them 颠茄叶表皮细胞形状和垂周壁式样在一些属和种中有一定的规律性，并与外部形态、孢粉学性状或地理分布相关；叶片表面角质膜的特征对属和种的划分也有一定意义。
4.
The cuticular membrane in the species of physochlaina is simultaneously striate , granular and scaly , while only striate , or occasionally granular in the species of hyoscyamus . 2 . seed morpholoy seed morphology of 25 species in seven genera of the tribe hyoscyameae and three related genera was investigated under sem for the first time 种子形态学在扫描电子显微镜下首次全面研究了天仙子族及颠茄属和茄参属等共10属25种植物的种子形态学特征，结果表明：该族植物种子表面纹饰有脑纹状或近脑纹状和网状两大类，除了山莨菪属anisodus和hyoscyamus
