Calandrinia pygmaea accepted name should be Rumicastrum nanum (Nees), ined
Calandrinia pygmaea F. Muell. (1859) is illegitimate under Art. 11.4, 52.1, because it is a homotypic synonym of Talinum nanum Nees (1845). Thus, the legitimate combination would have been "Calandrinia nana." However, the name "Calandrinia nana" subsequently was legitimately "usurped" by Philippi, Calandrinia nana Phil. (1894). So it no longer was available. In Calandrinia, the correct name is C. neesiana, which is the replacement name for the illegitimate Calandrinia pygmaea. The correct name should be Rumicastrum nanum (Nees), ined. Unfortunately, I erred and did not provide this combination in Phytologia 102(3): 116-123.
