Bromus commutatus Schrad., Fl. Germ.: 353 (1806)

Bromus commutatus Schrad., Fl. Germ.: 353 (1806). Type Protologue: "Inter segetes, ad vias, sepes, alibique". Type: Germany (lectotype designated by Acedo and Llamas 1999: 73): Bromus commutatus Fl. Germ. Göttingen GOET 006096!

Remarks.

The lectotype has a handwritten label by Schrader " B. commutatus / Fl. Germ. / Göttingen " and a handwritten indication as “typus-material”. Currently, there is another label on this sheet by H.Scholz 1998 marking it as Neotypus, which was published in Scholz (1999: 436). Although both publications fulfil the conditions for a formal typification of a lectotype or a neotype, the Acedo and Llamas (1999: 73) publication appeared in February and is probably the first typification (ICN, Art. 10. 5). There are two important facts to consider. First, according to Kerguélen (1975: 100), there is original material in GOET. We consulted that herbarium and found two sheets that Schrader sent to GFW Meyer, which are indeed original material. Both bear handwritten labels by Schrader. The first sheet label says " B. commutatus Fl. Germ. Göttingen” and the second sheet label " B. commutatus Fl. Germ. var. spic. paulo brevior. Göttingen”.
