Cytisus Striatus (Hill) Rothm. On Some Military Training Areas

Reported are two locations with Cytisus striatus at military areas, viz. the training area at the Galderse Heide and the military airbase Woensdrecht (Province of Noord-Brabant. Cytisus striatus is native to the Iberian Peninsula and has been introduced by sowing in France, Great Britain, Germany, and Belgium, where it has also established itself. As far as known, the reported populations represent the two first records of this species in the Netherlands. The origin of the plants at the Galderse Heide is uncertain, but the scrubs at the airbase Woensdrecht were planted as `autochtonous Cytisus scoparius'. The plants of the two Cytisus species show close resemblance. The most remarkable difference between the two species is found in the seed pods: the pods of C. striatus have conspicuous long grey hairs, whereas those of C. scoparius are (almost) glabrous. The vegetation in which the new species grows at the airbase Woensdrecht is shortly described based on a few vegetation releves.
