Figueiredo, E., G. F. Smith & R. Nyffeler (2013). August Wulfhorst (1861–1936) and his overlooked contributions on the flora of Angola. Candollea 68: 123–131. In English, English and French abstracts.
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.
