August Wulfhorst (1861-1936), a German missionary attached
to the Rheinische Missionsgesellschaft, collected material in
omupanda (Amboland, Uukuanyama), which is located in
present-day Angola. In the past, botanical collections from this
area were wrongly proposed as originating from Namibia, so
obscuring the occurrence of several taxa north of the borders
of this former German colony, in Angola.
