Een Orobanche als graanadventief
Gorteria Dutch Botanical Archives , Volume 2 - Issue 2 p. 22- 24
An Orobanche growing on Matricaria matricarioides (Less.) Porter was collected near a grain warehouse at Rotterdam harbour in 1935. The specimen was originally identified as O. minor Sm., but upon closer examination it appeared to be O. cernua Loefl. This is the first time that a species of this genus was found as an alien in the Netherlands.
