Nomenclatural notes — The protologue of Panicum semiundulatum mentions two syntypes, Schimper 289 and 1833. We have chosen the first, because of the large number of duplicates elsewhere, and the sheet at P, where Richard worked, as the lectotype. P holds a second sheet, with both numbers 289 and 1833 mounted on it; it seems best to regard that material as a duplicate rather than part of the lectotype material.

The protologue of Urochloa semiundulata indicates the volume is from 1993, but it was actually published in 1997.

Several varieties were described from India, but which are generally regarded as synonyms of a single variable species.
