Helicteres isora View in CoL L., Sp. Pl. 2: 963 (1753). – Type: [published illustration] “ Helicteres arbor

Ind. Or. siliqua varicosa, & funiculi in modum contortuplicata”, Plukenet, Phytographia, t. 245, f. 2 [closed fr. only] (1692) (lectotype designated by Howard, J. Arnold Arbor . 54: 454 [1973]) .

Helicteres roxburghii G.Don, Gen. Hist View in CoL 1: 506 (1831). – Type: W. Roxburgh s.n. [ EIC 1179 D] (lectotype K-W [ K001112333 ], designated here, including material labelled ‘a’ in pencil on sheet only).

George Don based Helicteres roxburghii View in CoL , at least in part, on Helicteres isora sensu Roxburgh. A Roxburgh View in CoL specimen in K-W is therefore selected as lectotype here.

Heliotropium paniculatum Roxb., Fl. Ind. View in CoL 2: 2 (1824), nom. illegit., non H. paniculatum R.Br. (1810) View in CoL . – Heliotropium roxburghii Spreng., Syst. Veg. View in CoL (ed. 16) 4(2, Cur. Post.): 54 (1827). – Heliotropium roxburghianum Voigt, Hort. Suburb. Calcutt. 445 (1845), nom. illegit, superfl.

Roxburgh’s name was a later homonym, so Sprengel renamed Heliotopium paniculatum as H. roxburghii View in CoL . Voigt’s Heliotropium roxburghianum is superfluous. The identity of the species remains uncertain, as there is no drawing or herbarium material available.

Hellenia globosa (Blume) S.R.Dutta, Pleione View in CoL 4: 152 (2010). – Costus globosus Blume, Enum. Pl. Javae View in CoL 62 (1827), nom. cons. prop. – Type: Indonesia, Java, Bantam, Tjoeroek Dinding , xi 1820, Van Hasselt s.n. (lectotype L [L.1480413], designated by Veldkamp, Taxon 67: 443 [2018]).

Costus roxburghii Hasselt, Bull. Sci. Nat. Geol. View in CoL 3: 189 (1824), nom. rej. prop. – Type : Indonesia, Java, Bantam, Tjoeroek Dinding , xi 1820, J.C.A. Van Hasselt s.n. (lectotype L [L.1480413], designated by Veldkamp, Taxon 67: 443 [2018]).

Costus roxburghii Hasselt View in CoL is an overlooked name for a Southeast Asian species. As it threatens the long-established epithet in use, there is a proposal submitted to conserve Costus globosus Blume View in CoL against C. roxburghii Hasselt View in CoL ( Veldkamp, 2018).

Heptapleurum venulosum (Wight & Arn.) Seem., J. Bot. View in CoL 3: 80 (1865). – Paratropia venulosa Wight & Arn., Prodr. Fl. Ind. Orient. View in CoL 377 (1834). – Schefflera venulosa (Wight & Arn.) Harms, Nat. Pflanzenfam. View in CoL 3(8): 39 (1894). – Type: Peninsula Ind. orientalis, R. Wight View in CoL s.n. [Cat. 1216] (lectotype K [K001129835], designated here).

Aralia digitata Roxb., Fl. Ind. View in CoL 2: 107 (1832), nom. illegit., non A. digitata Humb. & Bonpl. ex Willd. (1820) View in CoL . – Paratropia digitata Voigt, Hort. Suburb. Calcutt. View in CoL 25 (1845), nom. illegit., superfl. – Schefflera roxburghii Gamble, Fl. Madras View in CoL 570 (1919). – Heptapleurum venulosum var. roxburghii (Gamble) Haines, Bot. Bihar Orissa Pt 3: 416 (1922). – Schefflera venulosa var. roxburghii (Gamble) K.K.Khanna, J. Econ. View in CoL Taxon. Bot. 26: 144 (2002). – Type: W. Roxburgh s.n. [EIC 4920C] (lectotype K-W [K001104223], designated here).

Roxburgh described a South Indian species as Aralia digitata View in CoL . This was a later homonym. Wight and Walker-Arnott included Aralia digitata Roxb. View in CoL as a synonym of Paratropia venulosa Wight & Arn. Later, Gamble View in CoL published Schefflera roxburghii View in CoL as a replacement name for Aralia digitata Roxb. If View in CoL Paratropia venulosa Wight & Arn. View in CoL is treated as a replacement name for Aralia digitata Roxb. View in CoL , then Schefflera roxburghii Gamble View in CoL becomes superfluous and illegitimate.

The Code ( ICN Article 6.13; Turland et al., 2018) allows a name not explicitly proposed as a substitute to be a new taxon if the requirements for such are met. None of these names seems to have been typified. Because in the past the Roxburgh and Wight elements have been recognised as separate taxa, types are designated here to maintain that nomenclatural separation, even though presently they are no longer kept apart taxonomically .

Heterophragma quadriloculare (Roxb.) K.Schum., Nat. Pflanzenfam. IV , 3b: 243 (1895). – Bignonia quadrilocularis Roxb., Pl. Coromandel View in CoL 2: 24, t. 145 (1800). – Spathodea roxburghii Spreng., Syst. Veg. View in CoL 2: 835 (1825), nom. illegit., superfl. – Heterophragma roxburghii

DC., Prodr. 9: 210 (1845), nom. illegit., superfl. – Type: [published illustration] ‘ Bignonia quadrilocularis’, Roxburgh, Pl. Coromandel 2: t. 145 (1800) (lectotype designated here).

Spathodea roxburghii Spreng. and Heterophragma roxburghii DC. are superfluous renamings of Bignonia quadrilocularis Roxb. Roxburgh’s published plate is here designated as lectotype.

Heteropogon contortus (L.) P.Beauv. ex Roem. & Schult., Syst. Veg., ed. 15 bis, 2: 836 (1817). – Andropogon contortus L., Sp. Pl. 2: 1045 (1753). – Type: [published illustration] ‘Gram. Secalinum, Indicum , spica gracili, tomentoso, aristis longioribus, ad se invicem intortis’, Plukenet, Phytogr. 4: t. 191, f. 5 (1692) (lectotype designated by Cope, Fl. Pakistan 143: 312 [1982]).

Andropogon contortus subvar. roxburghii Hack., Monogr. Phan. 6: 586 (1889). – Heteropogon contortus subvar. roxburghii (Hack.) Domin, Biblioth. Bot. View in CoL 85: 276 (1915). – Type: India, prope urbem Mangalor, 1847, Plantae Indiae or. (Terr. Canara.) Ed. R.F. Hohenacker 301 (lectotype W [W 1889-0067344], designated here).

A specimen annotated with Hackel’s subvarietal name in W is here selected as lectotype.
