For classifying life forms of plants a proposal was made to use the principle of parallel divergence based on the hypothesis that life forms diverging to any degree preserve further the potential of evolving in a similar way, that is, in parallel series. Life forms of plants are divided into thirteen types corresponding to the nature of their basic metameres. Further, every type is divided into subtypes and sections according to the character of these metameres and then into smaller grades (classification units of the system of living forms corresponding to one trait and its evolutionary level) according to categories of traits: ramification, vegetative flexibility, rate of changes of metameres, types of habitat and environment. On the basis of the principle of parallel divergence scales of traits were constructed for each category. Corresponding to 26 paires of alternative traits 26 degrees of hierarchic classification were devised and within the limits of every type of life form there were 2(26) grades at the lowest rank. Separate systems were developed for single-celled and colonial forms.
为了对植物的生命形式进行分类，有人提出基于这样一种假设使用平行分歧原理，即任何程度上分歧的生命形式都进一步保留以相似方式进化的潜力，也就是以平行系列的方式进化。植物的生命形式根据其基本节段的性质分为13种类型。此外，每种类型又根据这些节段的特征分为亚型和亚组，然后根据性状类别分为更小的等级（与一个性状及其进化水平相对应的生活形式系统的分类单位）：分枝、营养柔韧性、节段变化速率、栖息地和环境类型。基于平行分歧原理，为每个类别构建了性状量表。对应于26对相对性状，设计了26个等级分类度，并且在每种生命形式类型的范围内，最低等级有2(26)个等级。为单细胞和群体形式分别开发了单独的系统。
