Pothoofdplant

Etymology
Compound of ; the Pothoofd was once a major transloading site in the port of Deventer in The Netherlands, back when Deventer was still an important port connected to the North Sea via the Zuiderzee and the river IJssel (today it is cut off from the ocean due to the damming in 1932 of the Zuiderzee, which is now a lake). The Pothoofd became a hotspot among botanists c. 1900 due to the prevalence of rare non-native plants which germinated there from seeds accidentally imported from distant lands (adventives), causing Pothoofdplanten to become, for some decades, emblematic for the phenomenon of adventive plants in the Netherlands in general.

Noun

 * 1)  An adventive, particularly one found around the Pothoofd in Deventer, The Netherlands.
