对混合丛生植物的野外观察结果表明，该植物是一种新的植物。(不包括胡萝卜属、胡萝卜属、安多属等)由几种不同的基因类型组成，没有任何修饰。在对标本馆材料的研究中，标本被分类为不同的表型，其名称取自文献。在Hypnum cupressiforme中，具有直叶的表达式(var.(Brivisetum Schimp.)也被区分为三个具有钩状叶片(var.UncinulatumBul.，var.Cpressiforme和var。)，通过翅细胞和锯齿状细胞的大小、数量和形状来区分。整个叶尖。瓦尔在观察过渡过程的基础上，初步认为亚菊科植物是空心Hypnum的高山变种，而丝状变种则被认为是变种。
Field observations of mixed tufts demonstrate that Hpynum cupressiforme s.str. (excl. imponens, jutlandicum, andoi etc.) consists of several different genotypes which are no modifications. Within a study of herbarium material, the specimens were sorted into different phenotypes, for which names were applied from the literature. Within Hypnum cupressiforme, an expression with straight leaves (var. brevisetum Schimp.) was distinguished as well three with hamate leaves (var. uncinulatum Boul., var. cupressiforme and var. plumosum Mart.), which are differentiated by the size, number and form of alar cells and serrate viz. entire leaf tips. Var. subjulaceum is tentatively regarded as alpine variety of Hypnum lacunosum, var, filiforme is regarded as modification based on the oberservation of transitions.
