Rumex kerneri in Belgium: towards a critical re-assessment of the R. patientia aggregate
A small but apparently well-established population of Rumex kerneri was recently discovered in the port-area of Gent (E-side of Kennedylaan, km 11.8-11.9, little N of the Texaco petrol station; IFBL C3.53.14). Several tens grow in a grassy bank between the roadside and a railway track (see photos). The species is rather reminiscent of Rumex patientia L. and might have been overlooked. Both might furthermore be confused with Rumex cristatus DC., an increasing species in neighbouring countries but apparently not yet recorded in Belgium.
