Abstract

We propose a nomenclatural revision of the names associated with the current circumscription of Fritzschia (Melastomataceae, Marcetieae). Lectotypes are designated for Comolia tetraquetra, Fritzschia anisostemon, F. caespitosa (≡ Marcetia caespitosa), F. punctulata, F. sessilis (≡ Melastoma sessile), Tetrameris excoriata, and T. violacea, and a neotype is designated for Fritzschia erecta. Three heterotypic synonyms are proposed under F. sessilis. In addition, Fritzschia caespitosa is proposed as a new combination based on the misunderstood name Marcetia caespitosa. Fritzschia recubans is treated as an excluded name proposed by Glaziou in his suppressed work “Plantae Brasiliae centralis a Glaziou lectae”. However, the gathering cited by Glaziou actually corresponds to Pleroma cleistoflorum. Finally, we clarify the circumstances involving type specimens of Fritzschia formerly housed at LE that were destroyed during their return following a loan.
