Based on Schenodorus benekenii Lange.

Remarks.

The current widely used name Bromus benenkenii is an implicit combination by Trimen (1872: 333) of the name described as Schedonorus benekenii Lange in Flora Danica. In the original publication, Lange (1871: 5) describes a perennial Bromus living in forests, with nodding panicle.

An exhaustive search to find the material Lange (1871) cites as models for the illustrations in table 2826 (figs 1, 2), finally had a result. The two syntypes are conserved in C in the Flora Danica subherbarium, that contains specimens drawn in the magnificent work "Flora Danica" (Olof Ryding pers. comm. 2018). Their labels state "insula Lolland legit cl. E. Rostrup" (C10021728)" and "Jonstrup Vang, legit cl. H. Mortensen" (C10021729). Each folder indicates in handwriting that the specimens were drawn for "Flora Danica".

We choose as lectotype the latter sheet since its spikelets conserve most of its florets. The other sheet is in a more advanced phenological state and conserves, in most of its spikelets, only the glumes. The Rostrup specimen still conserves its basal part, with leaves, that is missing in the lectotype.
