Bromus benekenii (Lange) Trimen, J. Bot. 10: 333. (1872)
Schedonorus benekenii
Lange, Flora Danica 48: 5, t. 2826. (1871). Type Protologue: "In silvia hinc inde. Specimen depictum fig. 1 in insula Lolland legit cl. E.
Rostrup
, specimen fig. 2 in silva Jonstrup Vang legit cl. H. Mortensen". Type: [Denmark] Jonstrup Vang. 29TH June 1866, H. Mortensen (lectotype, designated here: C [C10021729 image!]). (Figure 3)
Type.
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.
