About us


We are Jean Claessens and Jacques Kleynen and are interested in orchids for many years.

Our main interests are the details of the flower structure of the orchids and their relation to the pollinators. We studied flower morphology for many years and eventually included the visiting insects to our observations. We presented our results at various meetings of orchid enthousiasts (see the list below). A list of published articles can be found under the tab "Publications".

All observations and photos resulted in the publication of our book The flower of the European orchid - Form and function.
