已使用各种表型和分支方法对 18 个假设的进化单位（“Dendrogrammaceae”成员）的 20 个二进制特征的数据进行了分析。构建了来自单链接、完整链接、UPGMA 和 WPGMA 聚类分析的表型图、最短生成树图以及来自地平面散度、瓦格纳树和性状兼容性分析的分支图。将这些分析得出的表型图和分支图与每个分析得出的拓扑距离矩阵进行比较。比较最短生成树表型图和分支图的每个特征变化的数量和顺序。通过这些比较，讨论了每种方法作为表达生物体之间进化关系的手段的优点和局限性，并概述了一系列建议。每种方法都有助于对一组生物体的进化历史进行估计，但没有一种方法最适合此类研究。
Data for 20 binary characters for 18 hypothetical evolutionary units, members of "Dendrogrammaceae," have been analyzed using various phenetic and cladistic methods. Phenograms from single link, complete link, UPGMA, and WPGMA cluster analysis, shortest spanning tree diagrams, and cladograms from groundplan-divergence, Wagner tree, and character compatibility analyses were constructed. The phenograms and cladograms derived from these analyses were compared with respect to topological distance matrices derived from each. Shortest spanning tree phenograms and cladograms were compared for the number and sequence of character changes occurring on each. From these comparisons, the advantages and limitations of each method as a means for expressing evolutionary relationships among organisms are discussed and a series of recommendations is outlined. Each method can contribute to the development of an estimate of the evolutionary history for a group of organisms and no single method is best for such studies.
