Ophiorrhiza roxburghiana Wight, Icon. Pl. Ind. Orient. 3(4): 4, t. 1068 (1846). – Type: India,

Shevagherry , viii 1836, R. Wight s.n. (lectotype K [ K000031168 ], designated here) .

Robert Wight named this species to honour Roxburgh. Noltie (2005) referred to two possible types in K. The one bearing a date is designated as lectotype here. Someone has overwritten the date on the sheet and appears to have changed the final six in the year to a five.

Opuntia ficus-indica (L.) Mill., Gard. Dict. (ed. 8): Opuntia No. 2 (1768). – Cactus ficus-indica L., Sp. Pl. 1: 468 (1753). – Type: Anon. s.n. (neotype S [Herb. Linn. No. 201.7], designated by Leuenberger, Taxon 40: 624 [1991]).

Cactus chinensis Roxb., Fl. Ind. 2: 476 (1832). – Opuntia roxburghiana Voigt, Hort. Suburb. Calcutt. 62 (1845), nom. illegit., superfl. – Opuntia chinensis (Roxb.) K.Koch, Hort. Dendrol. 279, No. 6 (1854). – Type: [unpublished illustration] Icones Roxburghianae 2134 (lectotype K, designated here).

Voigt renamed Cactus chinensis Roxb. as Opuntia roxburghiana , but this is illegitimate. Roxburgh’s drawing is here designated as lectotype for Roxburgh’s name.

Oropetium roxburghianum (Schult.) S.M.Phillips, Kew Bull. 30: 469 (1975). – Rottboellia biflora Roxb., Fl. Ind. 1: 357–358 (1820), nom. illegit., non R. biflora Roth (1802) . – Rottboellia roxburghiana Schult. in Roemer & Schultes, Mant. 2: 430 (1824). – Lepturus roxburghianus (Schult.) Steud., Syn. Pl. Glumac. 1: 357 (1854). – Tripogon roxburghianus (Schult.) Bhide, J. Proc. Asiat. Soc. Bengal 7: 515 (1912) [‘1911’]. – Type: [unpublished illustration] Icones Roxburghianae 2112 (lectotype K, designated here). Figure 12 .

Schultes proposed Rottboellia roxburghiana as a new name for Roxburgh’s later homonym Rottboellia biflora . As no specimens have been located, Roxburgh’s drawing is here designated as lectotype.

Oxyceros kunstleri (King & Gamble) Tirveng., Nordic J. Bot. 3: 466 (1983). – Randia kunstleri King & Gamble, J. Asiat. Soc. Bengal, Pt 2, Nat. Hist. 72: 216 (1904). – Type: Silhet, N. Wallich s.n. [ EIC 8284 C] (lectotype K [ K000031454 ], designated here).

Randia roxburghii Ridl., J. Straits Branch Roy. Asiat. Soc. 79: 80 (1918). – Type: Singapore, ix 1822, N. Wallich 54 [ EIC 8284 D] (lectotype K-W [ K001125142 ], designated by Turner et al., Gard. Bull. Singapore 70: 373 [2018]).

Randia roxburghii Ridl. is a synonym of Oxyceros kunstleri (King & Gamble) Tirveng. Ridsdale (2007) proposed the specimen under number 8284C in K-W as the lectotype. But as ‘hic designatus’ or an equivalent was not included, this is not an effective designation. Here I select the specimen formerly in William Hooker’s herbarium now in K as the lectotype.

Pachygone laurifolia (DC.) L.Lian & Wei Wang, Molec. Phylogen. Ecol. 148(106825): 8 (2020). – Cocculus laurifolius DC., Syst. Nat. 1: 530 (1817). – Type : Inde, W. Roxburgh s.n. (lectotype G-DC [ G00201635 ] [two sheets], designated here).

Smilax roxburghiana Wall. ex A.DC., Mém. Soc. Phys. Genève 7: 314 (1836). – Type : Switzerland, Genève, Jard. de M. Saladin, vii 1834, Anon. s.n. (lectotype G [ G00413462 ], designated here).

Alphonse de Candolle described Smilax roxburghiana largely based on plants in cultivation in Geneva. More than 40 years later, he ( Candolle, 1878) noted that this species was not Smilax but the menisperm Cocculus laurifolius DC. (recently transferred to Pachygone ).

Paederia erecta Roxb., Fl. Ind. 2: 519 (1824), nom. illegit., non P. erecta Spreng. (1822) . – Paederia roxburghii Spreng., Syst. Veg. 4(2, Cur. Post.): 70 (1827). – Type: [unpublished illustration] Icones Roxburghianae 2196 (lectotype K, designated here). Figure 13 .

Sprengel’s Paederia roxburghii was published as a replacement for Roxburgh’s later homonym Paederia erecta . Roxburgh’s drawing seems to be the only extant original material for the name and is here designated as lectotype. The identity of the species remains uncertain.
