Chara papillosa Kütz. (Grijs kransblad) terug in Nederland
Gorteria Dutch Botanical Archives , Volume 42 - Issue 1 p. 19- 22
In 2015, Chara papillosa was found in a depression in a quaking bog in the Stobberibben, but this population was soon gone. The next year, however, the species was found again in a ditch in the Woldlakebos, where it occurred for three consecutive years. The areas of the Stobberibben and the Woldlakebos are adjacent to each other and belong to the Weerribben, a nature reserve in the northwest of the Province of Overijssel, the Netherlands. The only previous record of C. papillosa in the Netherlands dates from c. 1920, when material of this was species was collected in or near Huissen, Province of Gelderland, unfortunately without any further details about the precise location. In the depressions and ditches of the Stobberibben, several other charophyte species have been recorded: Chara aspera, C. contraria var. contraria, C. globularis var. globularis, C. hispida (syn. C. major), C. virgata, C. vulgaris var. vulgaris and var. papillata, Nitella flexilis, and Tolypella glomerata. In the ditch in the Woldakebos, C. papillosa was accompanied by Potamogeton alpinus, P. mucronatus, C. virgata, C. globularis, Sparganium emersum, and Myriophyllum verticillatum. This short communication describes the ecology of Chara papillosa, its distribution in Europe, as well as a few identification characters of this species.
