在解决海葵之间的关系的困难是在修订的家庭爱德华科的背景下探讨。这个科在讨论刺虫纲（刺虫纲，刺虫纲）内的关系中很重要，但一直没有得到很好的表征。爱德华科内的属以几个关键性状的马赛克分布为特征，其实际分布尚不清楚；广义的和理想化的形态学，而不是字符的实际分布，以前被用来划分属。肌肉和体壁的微观解剖，肌肉形状的定性和定量信息，以及线囊大小结合18s rDNA序列进行分支分析。结果表明，一些传统的诊断特征支持群体不同于以前认识到的。在几个先前提出的分类群或分支中确定了字符支持，包括Edwardsiella属和一个包含Nematostella和Drillactis的分支。爱德华科及其几个属是单系的；然而，在爱德华亚科的群需要修订和重新命名。爱德华属是单系的，这些资料不能将爱德华属划分为单系群。附加关键字。海葵，猕猴桃属
Difficulties in addressing relationships among sea anemones are explored in the context of a revision of the family Edwardsiidae. This family has been important in discussions of relationships within Zoantharia (Cnidaria, Anthozoa), but has been poorly characterized. Genera within Edwardsiidae are characterized by a mosaic distribution of a few key characters whose actual distribution is not well understood; generalized and idealized morphology, rather than the actual distribution of characters, has been previously used to delimit genera. Micro- anatomy of muscles and the body wall, qualitative and quantitative information about muscle shape, and nematocyst size are combined with 18s rDNA sequences in a cladistic analysis. The results demonstrate that some traditional diagnostic features support groups different from those previously recognized. Character support is identified for several previously proposed taxa or clades, including the genus Edwardsiella and a clade containing Nematostella and Drillactis. Edwardsiidae and several of its genera are monophyletic; however, groups within the subfamily Edwardsiinae require revision and recircumscription. The genus Edwardsia is paraphyletic, and these data do not resolve Edwardsia species into monophyletic groups. Additional key word.s: sea anemones, Actiniaria
