Discussion
Plants of Leibnitzia lyrata with cleistogamous heads are encountered and collected much more often than those with chasmogamous heads.
The combination Leibnitzia lyrata proposed by G. L. Nesom (1995) appeared to be based on Chaptalia lyrata D. Don (an illegitimate later homonym) but was actually based on Gerbera lyrata Schultz-Bipontinus, which was cited in synonymy by Nesom.
