Nat. Hist. II(13): Aanwyz. Plaat. [2], 315, tab. 91, fig. 4. 1782.

Lectotypus (designated here by Veldkamp): JAPAN: Thunberg s.n. (G-PREL [G00380028]!; isolecto-: UPS- THUNB n° 2503 image seen).

Notes. – The priority of the Houttuyn name has been overlooked by almost everyone, even MERRILL (1938), with the exception of a casual mention by NAKAI (1952: 136). Thunberg in MURRAY (1784: 119) described the isonym Bromus japonicus Thunb. (also cited in THUNBERG, 1784: 52, tab. 11). The type material of Houttuyn’s earlier name is in the Japan herbarium in G-PREL. PÉNZES (1936: 18) cited the type of Thunberg’s isonym at UPS-THUNB. This collection is here considered as an isolectotype.
