“…Our studies show that many herbarium sheets borrowed from selected herbaria (i.e., BR, BRNU, FR, G, KTU, M, MA, S, STU, WRSL, ZT, Z) and supposed to be E. purpurata are misidentified, even though the species is fairly easy to recognize [10]. In our opinion, these specimens belong to E. helleborine.…”

The identity of the holotype of Epipactis purpurata Sm. is shown to be demonstrably ambiguous because all its flowers are at the budding stage (pre-anthesis); thus, no crucial diagnostic characters are visible, i.e., gynostemium morphology and undulations of margins of the labella and their shape and color. This way, the specimen is almost identical with several species of Epipactis genus (E. purpurata group) and including morphologically variable Epipactis helleborine, as many plants of the latter species can have similar combinations of characters like the holotype (i.e., small leaves and a robust stem even in the inflorescence). Thus, an epitype for the name Epipactis purpurata Sm. is proposed (M 257866) in order to enable its precise taxonomic interpretation and achieve nomenclatural stability.

Results. We observed that in anthropogenic populations: i) shoots were higher than shoots 43 from natural populations, ii) flowers differed significantly in terms of ten biometric features 44 between habitats, iii) the genome size differed significantly between plants growing in natural 45 and anthropogenic habitats. Discussion. According to some researchers, the presence of 46 phenotypic variability and the occurrence of ecotypes are adaptation strategies of plants to 47 environmental changes. In our opinion, in the case of the studied anthropogenic habitats 48 (roadside) in which the E. helleborine populations grew, we can talk about ecofen due to the 49 often repeated set of characteristic features, i.e.: high shoots, long inflorescence and long, 50

“…Hunt & Summerh and Epipactis helleborine (L.) Crantz are species which the most frequently occupy anthropogenic habitats (Bîtea et al, 2011; Light & MacConaill, 2005; Light & MacConaill, 2006; Rewicz et al, 2017a; Wittig & Wittig, 2007). The genus Epipactis includes 15–80 species (Delforge, 2006; Jakubska-Busse et al, 2017; Kreutz & Fateryga, 2012; Pedersen & Mossberg, 2017) and systematics of this genus is complicated mainly due to similar morphological features.

BackgroundThe process of apophytism or spreading native species to human-made habitats is one of the main elements in the creation of plant cover in anthropogenic areas. Lately, an increase of anthropogenic localities with valuable flora has been observed. Apophytes are also members of the family Orchidaceae, especially from the genus Epipactis. The aim of the study was to (i) determine and compare the phenotypic variation of E. helleborine (L.) Crantz plants in anthropogenic and natural habitats, (ii) compare the genome size of plants growing in natural and anthropogenic habitats. The results reported in this study may indicate that a habitat influences morphological characteristics of plant species.MethodsField studies were conducted on four native stands and four stands in anthropogenic areas of E. helleborine in Poland in years 2011–2013. Biometrical analyses were performed on shoots and flowers. The flowers were characterised by 25 biometric features and measured using a Nikon SMZ 800 binocular, microscopic Moticam-1SP cameras and the MIPlus07 programme (Conbest Co.). The nuclear DNA content was determined in fresh and young leaves of E. helleborine, collected from four natural and four anthropogenic populations.ResultsWe observed that in anthropogenic populations: (i) shoots were higher than shoots from natural populations, (ii) flowers differed significantly in terms of ten biometric features between habitats, (iii) the genome size of some population differed significantly between plants growing in natural and anthropogenic habitats.DiscussionAccording to some researchers, the presence of phenotypic variability and the occurrence of ecotypes are adaptation strategies of plants to environmental changes. In our opinion, in the case of the studied anthropogenic habitats (roadside) in which the E. helleborine populations grew, we can talk about ecofen due to the often repeated set of characteristic features, i.e., high shoots, long inflorescence and long, broad leaves. We agree, however, that it is difficult to isolate a taxonomic unit for ecofen due to the lack of experimental research.
