Rigidulae is polyphyletic. However, the series is monophyletic if redefined to exclude C. brachyblepharis and C. ciliolata and include C. sincorana and C. botryoides (from series Microphyllae). The species in the series are all endemic to Brazil and can be divided geographically into two main lineages, one from the highlands of Goiás, and the second from the Espinhaço Range of Bahia and Minas Gerais.
