- Abstract
Geometric morphometric techniques were employed to assess the diversity of lip shapes (305 samples from 83 populations) in flowers of European RussianDactylorhiza(Orchidaceae: Orchidinae). We found significant agreement between the results from geometric morphometrics, classic morphometrics and the distribution of certain nuclear DNA markers. The lip shapes from ArcticDactylorhizasamples occupied an intermediate position betweenD. maculataandD. fuchsiisamples from Central Russia, supporting a hybrid origin of‘northern tetraploids’. Lip shapes of the taxonomically controversial allotetraploidD. balticawere found to form a distinct group, with members having definite relationships with diploidD. incarnatasamples from the same localities, indicating either their local origin or introgression withD. incarnata. In addition to demonstrating the value of geometric morphometric methods in studies of plant taxonomy and hybridization, we suggest future applications designed to explore pollinator-driven directional selection, developmental constraints and fluctuating asymmetry. © 2005 The Linnean Society of London,Biological Journal of the Linnean Society, 2005,85, 1–12.
