Polygala apiculata is studied on living plants from the locus classicus. 2n = 24 chromosomes were counted, indicating a possibly triploid genomic constitution. The species is unique in the genus for the crown-like arranged caruncle lobes of its seeds. Its occurrence is confirmed for Calabria only and the IUCN conservation status “Critically Endangered” is proposed. A lectotype of the name P. apiculata is designated.
