Turner, Ian M., 2022, FROM ACACIA TO ZIZIPHUS: PLANT NAMES COMMEMORATING THE BOTANIST WILLIAM ROXBURGH, Edinburgh Journal of Botany 79 (1911), pp. 1-102 : 77-79

Potamogeton nodosus Poir. in Lamarck, Encycl., Suppl. 4: 535 (1816), as ‘nodosum’. – Type:

Canary Isl. , Broussonet s.n. (lectotype P [ P00083340 ], designated by Kaplan & Symoens, Bot. J. Linn. Soc. 148: 333 [2005]) .

Potamogeton indicus Roxb., Fl. Ind. 1: 471–472 (1820), as ‘indicum’, nom. illegit., non P. indicus Roth (1818) . – Potamogeton roxburghianus Schult.f., Mant. 3: 367 (1827). – Type: W. Roxburgh s.n. (lectotype BM [BM000522406], designated here).

Potamogeton roxburghianus Schult.f. is a replacement name for Roxburgh’s later homonym Potamogeton indicus . A Roxburgh specimen in BM is here designated as lectotype.

Pothos roxburghii de Vriese in Miquel, Pl. Jungh. 1: 103 (1851). – Pothos neoroxburghii P.C.Boyce, Thai Forest Bull., Bot. 37: 21 (2009), nom. illegit., superfl. – Type: Silhet, F. da Silva s.n. [ EIC 4435 D] (lectotype L [L.1417830], designated by Boyce & Hay, Telopea 9: 462 [2001]; isolectotypes K-W [ K001038992 ], LE [ LE00010595 ], U [U.1097725]).

De Vriese based Pothos roxburghiana partly on Roxburgh’s description of Pothos scandens .

Primula rotundifolia Wall. in Roxburgh, Fl. Ind. 2: 18 (1824). – Primula roxburghii N.P.Balakr., J. Bombay Nat. Hist. Soc. 67: 63 (1970), nom. illegit., superfl. – Type: Nepal, Gossain Than, 1818, E. Gardner s.n. (lectotype BM [000521881(BM)], designated by Gould, Enum. Fl. Pl. Nepal 3: 74 [1982]).

Balakrishnan proposed Primula roxburghii as a replacement name for Primula rotundifolia Wall. , but the supposed senior homonym was not validly published, making Balakrishnan’s name superfluous.

Priva cordifolia (L.f.) Druce, Rep. Bot. Soc. Exch. Club Brit. Isles 1916: 641 (1917). – Buchnera cordifolia L.f., Suppl. Pl. 287 (1781). – Type: 1770, J. G. Koenig s.n. (lectotype LINN [ LINN-HL 790.2 ], designated by Moldenke & Moldenke, Rev. Handb. Fl. Ceylon 4: 268 [1983]) .

Streptium asperum Roxb., Pl. Coromandel 2: 25, t. 146 (1800). – Priva roxburghii Endl., Cat. Horti Vindob. 2: 47 (1842). – Type: [published illustration] ‘ Streptium asperum’, Roxburgh, Pl. Coromandel 2: t. 146 (1800) (lectotype designated here).

Endlicher’s Priva roxburghii is not superfluous as Priva aspera Kunth blocked a simple transfer of Roxburgh’s name. Roxburgh’s plate is here designated as lectotype of Streptium asperum . There are Roxburgh specimens in BR, but it is not clear whether these were collected before 1800.

Pseudopogonatherum trispicatum (Schult.) Ohwi, Bull. Tokyo Sci. Mus . 18: 3 (1947). – Andropogon tristachyos Roxb., Fl. Ind. 1: 261 (1820), nom. illegit., non A. tristachyus Kunth (1816) . – Andropogon trispicatus Schult., Mant. 2: 452 (1824). – Erianthus roxburghii F.Muell., Fragm. 9: 279 (1873), nom. illegit., superfl. – Eulalia trispicata (Schult.) Henrard, Blumea 3: 453 (1940). – Type: [unpublished illustration] Icones Roxburghianae 1938 (lectotype K, designated by Cope in Nasir & Ali, Fl. Pakistan 143: 276 [1982]).

Erianthus roxburghii F.Muell. is a superfluous renaming of Andropogon trispicatus Schult.

Psychotria roxburghii DC., Prodr. 4: 519 (1830). – Psychotria asiatica Roxb., Fl. Ind. 2: 160 (1824), non P. asiatic a L. (1759). – Uragoga roxburghii (DC.) Kuntze, Revis. Gen. Pl. 2: 962 (1891). – Type: W. Roxburgh 2630 (lectotype BR [BR0000005745487], designated here). De Candolle based Psychotria roxburghii on Roxburgh’s description of Psychotria asiatica from the Moluccas and Wallich’s accompanying notes on a plant from Silhet (probably Psychotria calocarpa Kurz ). To maintain the application of the name to the Moluccan plant as currently used, a Roxburgh specimen in BR is here selected as lectotype.

Pterocarpus roxburghii G.Don, Gen. Hist. 2: 377 (1832). – Type: non designatus.

The identity of George Don’s species remains uncertain.
