Nomenclatural notes — The type of Panicum dictyoneurum was already identified by Clayton & Renvoize (1982) as being a collection of Figari at FI. However, there are two sheets at FI, which have slightly different labels, and we have chosen the one with the original label from the herbarium of Figari as the lectotype. The other seems to be a duplicate that may have been located elsewhere (Florence?) before it came (back) to FI.

The protologue of Panicum albovellerum cites two syntypes, Holst 4015 from Usambara-Bonda and Hildebrandt 2663 from Kitui. Apart from a fragment at K, the second could not be located, but a fine specimen of the first is present at B and forms the obvious choice as the lectotype; there is also a fragment at K .
