Notes.

The holotype of Acalypha buchenavii should be at BREM but Rutenberg’s specimens arrived at BRNU after World War II. Originally in the Überseemuseum in Bremen (BREM), they were transferred to northern Moravia (Czechia was at that time a Protectorate of Nazi Germany) to save them from potential destruction by bombardment. After the collapse of the Nazi regime, these collections were confiscated as "German property" and sent to BRNU.
