Turner, Ian M., 2022, FROM ACACIA TO ZIZIPHUS: PLANT NAMES COMMEMORATING THE BOTANIST WILLIAM ROXBURGH, Edinburgh Journal of Botany 79 (1911), pp. 1-102 : 51-52

Grewia rothii DC., Prodr. 1: 509 (1824). – Grewia bicolor Roth , Nov. Pl. Sp. 240 (1821),

nom. illegit., non G. bicolor Juss. (1804) . – Type: Anon. s.n. [ex Herb. Rottler] (neotype K [ K001129699 ], designated by Turner, Taxon 70: 391 [2021]) .

Grewia roxburghii G.Don, Gen. Hist. 1: 548 (1831). – Type: B. Heyne s.n. [ EIC 1091 .[1]] (lectotype K-W [ K001112022 ], designated here).

Grewia salviifolia Roxb., Fl. Ind. 2: 587 (1832), as ‘ salvifolia ’, nom. illegit., non G. salviifolia L.f. (1782), nec G. salvifolia B.Heyne ex Roth (1821) . – Type: [unpublished illustration] Icones Roxburghianae 225 (lectotype K, designated here).

George Don clearly realised that Roxburgh’s Grewia salviifolia was a later homonym (or would be when it was validated). He therefore used Grewia roxburghii for it. A Heyne specimen in K-W included by Wallich under Roxburgh’s name is here selected as lectotype of Don’s name. Roxburgh’s name is lectotypified to one of his illustrations in K.

Habenaria roxburghii Nicolson in Saldanha & Nicolson, Fl. Hassan Distr. 834 (1976). – Orchis plantaginea Roxb., Pl. Coromandel 1: 32, t. 37 (1795). – Orchis platyphyllos Willd., Sp. Pl. 4: 11 (1805), nom. illegit., superfl. – Orchis roxburghii Pers., Syn. Pl. 2(2): 503 (1807), nom. illegit., superfl. – Habenaria platyphylla Spreng., Syst. Veg. ed. 16, 3: 690 (1826), nom. illegit., superfl. – Pecteilis roxburghii (Nicolson) M.A.Clem. & D.L.Jones, Austral. Orchid Rev. 83(6): 53 (2018). – Type: [published illustration] ‘ Orchis plantaginea’, Roxburgh, Pl. Coromandel 1: t. 37 (1795) (lectotype designated here).

The transfer of Orchis plantaginea Roxb. to Habenaria is blocked by Habenaria plantaginea Lindl. , so Nicolson published Habenaria roxburghii . As no Roxburgh specimens have been located, Roxburgh’s plate is here designated as lectotype.

Hedychium roxburghii Blume, Enum. Pl. Javae 1: 57 (1827). – Gandasulium roxburghii (Blume) Kuntze, Revis. Gen. Pl. 2: 690 (1891). – Type: Java, C.L. Blume 488 (lectotype L [L0041122], designated here; isolectotype L [L0041121]).

Blume named this Indonesian ginger after Roxburgh. A Blume specimen in L is here designated as lectotype.
