Determination key for Central European Epilobium species based on trichome morphology

Abstract

Strgulc Krajšek S., Dermastia M. and Jogan N. 2006. Determination key for Central European Epilobium species based on trichome morphology. Bot. Helv. 116: 169 -178.The distribution and morphology of trichomes was investigated for 14 European Epilobium species (section synstigma) to evaluate their taxonomic relevance. Three kinds of trichomes were detected. Tapering trichomes without glandular activity occurred in all examined species but differed in their distribution on the plant. Blunt trichomes with a rounded tip were only present in some of the species. They were of two types, one of which possessed glandular activity. Together, trichomes characteristics allowed a clear distinction of the 14 species and were included in a determination key.

“…Raw plant materials were dried in the shade at room temperature and cut. Botanical identification was performed as described previously . The voucher specimens of the plant materials were deposited in the collection of the Department of Pharmacognosy and Molecular Basis of Phytotherapy, Medical University, Warsaw, Poland.…”

“…Botanical identification was performed as described previously. [1,4] The voucher specimens of the plant materials were deposited in the collection of the Department of Pharmacognosy and Molecular Basis of Phytotherapy, Medical University, Warsaw, Poland. Powdered plant materials (50 g) were extracted (1 h) with water (1:10) at 40°C, using an ultrasonic water bath.…”

“…Different species are collected as plant sources, including small‐flowered species, such as Epilobium parviflorum , E. montanum and E. roseum , and large‐flowered species, such as E. angustifolium and E. hirsutum . Authentication is difficult because similarity among the species and frequent interspecific hybridisation requires a combination of chromatographical and morphological (trichomes and raphides) analyses . However, the most popular are E. angustifolium L., E. parviflorum Schreb.…”

A Synopsis of Cytology and Cytogeography of Tribe Epilobieae Endl. (Onagraceae)

“…However, there is ambiguity in distinction between Epilobium and Chamerion. Epilobium is taxonomically a difficult group due to its passably invariable outer appearance and frequent intraspecific hybridization (Krajsek et al 2006). The current paper follows the classification given by Wagner et al (2007).…”
