"From the situation mentioned above it emerges without any doubt that G. carminanthum was not described in accordance with the rules and thus the name is invalid. Precisely because of its red flower, G. carminanthum is very popular and common among collectors. To be able to continue using this name it might be necessary to establish a new formal description of the taxon carminanthum, ignoring at present its position within the plant system. A description of the taxon was already published in 1976, and reference to this description is made at this point. In this paper only a nomenclatoral type shall be defined."
