Turner, Ian M., 2022, FROM ACACIA TO ZIZIPHUS: PLANT NAMES COMMEMORATING THE BOTANIST WILLIAM ROXBURGH, Edinburgh Journal of Botany 79 (1911), pp. 1-102 : 72

Panicum curViflorum Hornem., Hort. Bot. Hafn., Suppl. 116 (1819). – Type: non designatus.

Panicum tenellum Roxb., Fl. Ind. 1: 309 (1820), nom. illegit., non P. tenellum Lam. (1791) .

– Panicum trypheron Schult., Mant. 2: 244 (1824) [Schult. before Spreng.]. – Panicum roxburghii Spreng., Syst. Veg. 1: 320 (1824), nom. illegit., superfl. – Type: [unpublished illustration] Icones Roxburghianae 814 (lectotype K, designated here).

Veldkamp et al. (1989) noted that Panicum curviflorum Hornem. was the oldest name available for the grass species then generally referred to as P. trypheron Schult. Veldkamp et al. (1989) were not able to locate any original material for Hornemann’s name. They therefore designated a neotype, selecting the type of Panicum tenellum Roxb. as the neotype of P. curviflorum Hornem. They referred to this as a ‘Hb. Roxburgh specimen in BM’. Veldkamp (1996) later reported this as ‘ Hb. Roxburgh 814 ’. I have failed to locate any Roxburgh collection in BM that is relevant to these names. That Veldkamp used Roxburgh’s icon number for the supposed herbarium specimen inclines me to think Veldkamp did not actually see any specimen in BM either, so the typifications do not stand. As no Roxburgh specimens of this taxon have been located by me, I select Roxburgh’s drawing in K as lectotype of Panicum tenellum Roxb.
