Celtis tetrandra Roxb., Fl. Ind. 2: 63 (1832). – Type: [unpublished illustration] Icones

Roxburghianae 1999 (lectotype K, designated by Akhter, Fl. Pakistan 170: 10 [1985]) .

Bosea trinervia Roxb., Fl. Ind. 2: 87 (1832). – Celtis roxburghii Voigt, Hort. Suburb. Calcutt. 294 (1845). – Celtis trinervia (Roxb.) Koord., Exkursionsfl. Java 2: 76 (1912), nom. illegit., superfl., non C. trinervia Lam. (1797) , nec C. trinervia Roxb. (1832) . – Type: [unpublished illustration] Icones Roxburghianae 134 (lectotype K, designated here).

Celtis trinervia Roxb., Fl. Ind. 2: 65 (1832), nom. illegit., non C. trinervia Lam. (1797) . – Celtis roxburghii Planch., Ann. Sci. Nat., Bot., Sér. 3, 10: 302 (1848), as ‘Roxburgii’, non C. roxburghii Voigt (1845) . – Type: [unpublished illustrations] Icones Roxburghianae 2211 (lectotype K, designated here).

Voigt recognised that Bosea trinervia Roxb. when transferred to Celtis required a new name as Celtis trinervia Lam. and C. trinervia Roxb. blocked a new combination. Therefore, he proposed Celtis roxburghii Voigt. Roxburgh’s drawing is here designated as lectotype, as no herbarium specimens have been located. Planchon also proposed Celtis roxburghii as a replacement name, this time for C. trinervia Roxb.

Cenchrus americanus (L.) Morrone, Ann. Bot. (Oxford) 106: 127 (2010). – Panicum americanum L., Sp. Pl. 1: 56 (1753). – Type: [published illustration] ‘ Panicum Americanum’, Clusius, Rar. Pl. Hist. 2: ccxv (1601) (lectotype designated by Clayton & Renvoize in Polhill, Fl. Trop. E. Africa, Gramineae 3: 672 [1982]).

Holcus spicatus L., Syst. Nat. 1305 (1759). – Panicum spicatum (L.) Roxb., Hort. Bengal. 7 (1814). – Penicillaria roxburghii A.Braun & C.D.Bouché, Index Seminum [Berlin] 26 (1855), nom. illegit., superfl. – Type: [published illustration] ‘Gr. Alopecuroid. spica max. Ind. Orient.’, Plukenet, Phytographia t. 32, f. 4 (1691) (lectotype designated by Davidse in Dassanayake et al., Rev. Handb. Fl. Ceylon 8: 363 [1994]).

Panicum spicatum Roxb. was cited as a synonym in the protologue of Penicillaria roxburghii A.Braun & C.D.Bouché , making the latter superfluous.

Centaurium brachiatum (Willd.) I. M.Turner, comb.nov. – Erythraea brachiata Willd. in Roemer & Schultes, Syst. Veg., ed. 15 bis, 4: 787 (1819). – Type: India, J. G. Klein 809 [ B. Heyne leg.] (lectotype B-W [ B - W -4518 -00 0], designated here) .

Chironia centaurioides Roxb., Fl. Ind. 2: 283–284 (1824), as ‘centaureoides’. – Erythraea roxburghii G.Don, Gen. Hist. 4: 206 (1837), nom. illegit., superfl. – Centaurium roxburghii Druce, Rep. Bot. Soc. Exch. Club Brit. Isles 4 (Suppl. 2): 614 (1917), nom. illegit., superfl. – Centaurium centaurioides (Roxb.) S.R.Rao & Hemadri, J. Bombay Nat. Hist. Soc. 67: 357 (1970). – Type: India, W. Roxburgh s.n. (lectotype BM [BM001914661], designated here).

Erythraea roxburghii G.Don and Centaurium roxburghii Druce are superfluous renamings of Chironia centaurioides Roxb. A Roxburgh specimen in BM is here designated as lectotype for Roxburgh’s name. Willdenow’s name, Erythraea brachiata , represents an earlier synonym for this species, so a new combination is proposed in Centaurium for it.

Ceriops decandra (Griff.) W.Theob. in Mason, Burmah, ed. 3, 2: 480 (1883). – Bruguiera decandra Griff., Trans. Med. Soc. Calcutta 8: 10 (1836). – Type: [unpublished illustration] Icones Roxburghianae 1140 (lectotype K, designated by Ekanayake et al., Taprobanica 8: 38 [2016]).

Ceriops roxburghiana Arn., Ann. Nat. Hist. 1(5): 364 (1838). – Type: Sundriban, 24 ix 1809, F. Buchanan-Hamilton s.n. [ EIC 4875 A] (lectotype K-W [ K001104122 ], designated here).

A lectotype for Ceriops roxburghiana Arn. is designated here. Walker-Arnott’s name was published two years after Griffith validated Bruguiera decandra . Griffith’s account noted Martaban and Mergui (now in Myanmar) as localities for the new species, probably to indicate specimens were made, but none has yet been located. Therefore, the lectotypification to Roxburgh’s drawing in K by Ekanayake et al. (2016) is accepted here.
