Abstract

Hypericum haplophylloides Halácsy & Bald is an endemic St. John’s wort of Albania described by Halácsy in 1892, with locus classicus in Llogara, Vlora district. According to Meyer, the distribution of this species is wider in Albania, and it’s represented by two subspecies: H. haplophylloides subps. haplophylloides and H. haplophylloides subsp. devollense, which are phyto-geographically divided and grow in different substrate types. Described almost a century later, there are still a lot of scientific discussions about accepting of these subspecies as new taxa, considering them as ecotypes or just high phenotypic plasticity of the species. In this study we aim to notice if there is any significant statistical difference between them based on some parametric measurements of leaves, sepals, and fruits; features that make the differences according to F.K. Meyer. The results indicated that: there is no significant difference between the two subspecies related to length of leaves, but the leaves width of subsp. devollense is significantly bigger. There is a significant difference between subspecies concerning the fruit’s size. They are larger to subsp. haplophylloides, but significant differences of fruit’s size exist even between different populations of the same subspecies. Subsp. haplophylloides results to have lengthier sepals than subsp. devollense, but the sepals are wider to subsp. devollense. These wide variations which are not considered by Meyer, probably reflection of different ecological conditions of habitats where H. haplophylloides grows, supporting the presence of different ecotypes and/or high phenotypic plasticity. Genetics studies are highly recommended.

不同种群中金丝桃形态特征的比较分析
摘要 Hypericum haplophylloides Halácsy & Bald 是阿尔巴尼亚特有的圣约翰草,由 Halácsy 于 1892 年描述,产地位于发罗拉地区的 Llogara。根据 Meyer 的研究,该物种在阿尔巴尼亚分布较广,有两个亚种:haplophylloides subsps. haplophylloides 和 H. haplophylloides subsp.在描述了近一个世纪之后,关于是否接受这些亚种为新类群、将其视为生态型或只是该物种的高表型可塑性,仍有很多科学讨论。在这项研究中,我们的目的是根据叶片、萼片和果实的一些参数测量结果,了解它们之间是否存在显著的统计学差异;F.K. Meyer 认为,这些特征是造成差异的原因。结果表明:两个亚种在叶长方面没有明显差异,但 devollense 亚种的叶宽明显更大。亚种之间在果实大小方面有明显差异。与 haplophylloides 亚种相比,它们的果实更大,但即使在同一亚种的不同种群之间,果实的大小也存在显著差异。haplophylloides 亚种的萼片比 devollense 亚种长,但 devollense 亚种的萼片比 haplophylloides 亚种宽。Meyer 没有考虑到这些巨大差异,它们可能反映了 H. haplophylloides 生长栖息地的不同生态条件,支持不同生态型和/或高表型可塑性的存在。强烈建议进行遗传学研究。
