Turner, Ian M., 2022, FROM ACACIA TO ZIZIPHUS: PLANT NAMES COMMEMORATING THE BOTANIST WILLIAM ROXBURGH, Edinburgh Journal of Botany 79 (1911), pp. 1-102 : 55-57

Hygrophila ringens (L.) R.Br. ex Steud., Nomencl. Bot. 1: 418 (1821). – Ruellia ringens L.,

Sp. Pl. 2: 635 (1753). – Type: Anon. s.n. (lectotype LINN [ LINN-HL 804.13 ], designated by Hansen in Nicolson et al. (ed.), Interpret. Van Rheede’s Hort. Malab. 40 [1988]) .

Hygrophila phlomoides var. roxburghii C.B.Clarke, Fl. Brit. India 4(11): 408 (1884). – Type : Botanical Garden [Calcutta], 9 i 1815, F. Buchanan-Hamilton s.n. [ EIC 2375 ] (lectotype K-W [ K001115795 ], designated here).

Clarke cited the Wallich Catalogue number 2375 in the protologue of his var. roxburghii . The specimen in K-W is here designated as lectotype for this name.

Hypobathrum racemosum (Roxb.) Kurz, Prelim. Rep. Forest Pegu, App. B: 59 (1875). – Randia racemosa Roxb., Fl. Ind. 2: 144–145 (1824). – Petunga roxburghii DC., Prodr. 4: 399 (1830), nom. illegit., superfl. – Type: [unpublished illustration] Icones Roxburghianae 1207 (lectotype K, designated here). Figure 9 .

Petunga roxburghii DC. represents a superfluous renaming of Randia racemosa Roxb. De Candolle objected to Roxburgh’s epithet because the inflorescences are spicate rather than racemose. Roxburgh’s drawing, labelled Ixora polysperma , is here selected as lectotype for Roxburgh’s name.

Indigofera coerulea Roxb., Trans. Soc. London Encour. Arts 28: 294–296 (1811). – Indigofera roxburghiana J.St. -Hil., Mém. Indigof. Bengale 9 (1826), nom. illegit., superfl. – Indigofera argentea var. coerulea (Roxb.) Baker in Hooker, Fl. Brit. India 2(4): 99 (1876). – Type: W. Roxburgh s.n. (lectotype BR [BR0000005170104], designated by Turner, Willdenowia 44: 24 [2014]).

Jaume Saint-Hilaire proposed Indigofera roxburghiana as a replacement name for Indigofera coerulea Roxb. , as he believed Roxburgh’s name was a later homonym of I. coerulea L.f. However, Linnaeus filius never published this name. Possibly Jaume Saint-Hilaire confused Galega coerulea L.f. with Indigofera .

Indigofera linifolia (L.f.) Retz., Observ. Bot. 4: 29 (1786). – Hedysarum linifolium L.f., Suppl. Pl. 331 (1782). – Type: Ind. orient., Anon. s.n. (lectotype LINN [ LINN-HL 921.5 ], designated by Ali, Bot. Notiser 111: 543 [1958]) .

Indigofera roxburghii Tausch , Flora 14(2): 671 (1831). – Type [published illustration] ‘ Indigofera linifolia’, Roxburgh, Pl. Coromandel 2: t. 195 (1805) (lectotype designated here).

Tausch based Indigofera roxburghii on Indigofera linifolia sensu Roxb. Roxburgh’s plate is here selected as lectotype of Tausch’s name.
