Although Pulsatilla can easily be distinguished from Anemone by the former having a long, plumose beak on the achenes formed by the persistent style, phylogenetic studies have shown that they are probably congeneric.
尽管Pulsatilla 能容易地通过其在瘦果上有宿存花柱形成的长的、羽状喙,与银莲花属区分,系统发育的研究显示它们可能是同属。

The phylogeny of the genus Machilus was analysed by means of Bayesian Inference of nrDNA ITS sequences . Our results indicated that Machilus is a monophyletic clade within the Persea group, and its persistent and spreading to reflexed tepals on fruit are an important character for its generic delimitation against the related genera Phoebe, Alseodaphne and Persea .
应用nrDNA Internal Transcribed Spacer 序列,使用Bayesian 分析法对樟科润楠属的系统学问题进行了初步探讨,结果表明润楠属在鳄梨属群中本身作为一独立分支,是一个自然的单系类群;由于其花被裂片果期宿存且强烈反转与同产自亚洲的楠属和油丹属存在清晰界线。

Disk absent. Ovary ovoid, cylindrical, or bottle-shaped, glabrous or hairy, many loculed; ovules numerous per locule; styles as many as carpels (15-30), usually reflexed, persistent, radiating, in functionally female flower elongating after anthesis; rudimentary ovary in functionally male flower very small, with minute styles.
花盘无。子房卵球形,圆筒状的,或瓶形的,无毛或有毛的,很多室的;胚珠多数每室;花柱同数于心皮(15-30),通常反折,宿存,辐射状,功能上的雌花花后延长;功能上的雄花不发育子房很小,具小的花柱。

Moreover,in this dissertation,a method ispresented to control safe basin with the fractal erosion,that is by the application ofthe weak parameter periodic perturbation with an optimal frequency to control thefractal erosion basin,and the analytical study shows that the essence of the methodis that the parameter periodic perturbation can be used to delay the occurrence ofhomoclinic tangencies.
并且在本文提出了一种对分形侵蚀安全域进行控制的方法,那就是应用具有最优频率的参数周期扰动对于已受到分形侵蚀的安全域加以控制,在理论分析中得到这种控制分形侵蚀安全域的方法实质上延缓了鞍点同宿相切的发生,同时考虑了外加噪声对控制后安全域的影响,得到这种控制方法具有很好的鲁棒性。
