- Abstract
- Morphometric and multivariate analyses on 17 populations of D. praetermissa in France, Belgium, the Netherlands and Germany show considerable inter-population variability that is here resolved as ten variants. Three of these are referable to typical D. praetermissa, one to subsp. integrata, and two trend towards the related species D. elata. The last four variants (corresponding to six of the initial populations) are remarkably homogeneous, and are probably recently established, clonal populations. They should be observed over the next few years to check whether they develop into new populations of the typical species. A few populations, resembling D. praetermissa but growing in the French Alps, far outside the normal distribution area, may have arisen through hybridizations similar to those that we regard as responsible for the origination of D. praetermissa. However, they show considerable morphological differences from D. praetermissa and are not referable to it. They are given provisional, informal names after the localities where they grow.
