Creeping woodsorrel, a global weed

Creeping woodsorrel (Oxalis corniculata) has spread to every country in the world from its origins in South America and Australasia. It has spread by itself and by the actions of people, either by accident or on purpose. We are researching how it has spread, its evolution and origins. We hope to better understand how this species can be successful practically everywhere.
In this expedition you explore the international collections of the Botanic Garden Meise in Belgium. These specimens come from all over the world and it is going to be tricky to geolocate them, particularly as the labels are in many languages. Nevertheless, we hope to use these data to model the habit requirements of this species and need to accurately locate them to do this.This expedition of 249 tasks is fully transcribed and validated.
