Orchid taxonomy can take some interesting turns. This has just happened to Caladenia haemantha. Based upon the examination of the type specimens collected for C haemantha and C formosa, authors Andrew McDougall & Timothy Hammer have just published an article reinstating C haemantha as C formosa.
Soon after C formosa was described and named in 1991 by GW Carr, David L Jones came along and described and named C haemantha; but in 1993, Mark Clements took a look and listed it as a synonymy of C formosa, where is stayed for many years until 2021 when Jones reinstated it as C haemantha.
But, through the beauty of science, along comes Andrew and Tim to have a closer look at the two type specimens. Meticulously they counted the details and duly documented their findings. Their conclusion – C haemantha is a synonym of C formosa.
