Abstract

The taxonomic history, nomenclature and application of one of the oldest species names in Pilosella are reviewed. Hieracium floribundum originally included a hybrid swarm with the participation of Pilosella lactucella, P. caespitosa, P. praealta and partly P. officinarum, and was interpreted either as a binary (P. lactucella × P. caespitosa) or triple (P. lactucella × P. caespitosa × P. praealta) hybrid. The original material of H. floribundum from Silesia, Poland includes plants of the triple hybrid which are designated as its lectotype in conformity with the usage of the species name that has been predominant during its history. The lectotype belongs to a morphotype in which the diagnostic characters of P. lactucella are dominant, and which is not typical of northern and eastern Europe. A further lectotype from the same hybrid complex is designated for H. floribundum var. subcymosum.

欧洲中部、北部和东部常见杂交聚合植物 Pilosella floribunda（菊科）的分类学历史

本文回顾了 Pilosella 最古老的种名之一的分类历史、命名和应用。Hieracium floribundum 最初包括一个杂交群，其中有 Pilosella lactucella、P. caespitosa、P. praealta 和部分 P. officinarum 的参与，被解释为二元（P. lactucella × P. caespitosa）或三元（P. lactucella × P. caespitosa × P. praealta）杂交种。来自波兰西里西亚的 H. floribundum 原始材料中包括三系杂交种的植株，根据种名在其历史上的主要用法，将其指定为标准模式。该模式标本属于一种形态类型，其中 P. lactucella 的诊断特征占主导地位，这在北欧和东欧并不典型。来自同一杂交复合体的另一个标本被指定为 H. floribundum var.
