Brachypodium xcugnacii A. Camus nieuw voor Nederland

Brachypodium xcugnacii, the hybrid of B. pinnatum and B. sylvaticum, has originated spontaneously in a vegetation with the parental species at the transition between calcareous grassland and scrub in the first author's ecological experimental garden in Scherpenzeel (The Netherlands) in a vegetation gradient between calcareous grassland and scrub. The hybrid has chromosome number 23, which is intermediate to that of the parental species (being 28 and 18, respectively). The features of B. xcugnacii are largely intermediate to those of the parental species. In 2006, a plant with intermediate features was also found in the southern part of the Province of Limburg, The Netherlands. Presumably, this plant also belongs to B. xcugnacii, even though this has not yet been confirmed by chromosome researc
