Macaranga involucrata (Roxb.) Baill. ex Müll.Arg. View in CoL in Candolle, Prodr. 15(2): 1011 (1866).

Urtica involucrata Roxb., Fl. Ind. View in CoL 3: 592 (1832), nom. cons. prop. [non U. involucrata

Sims (1824)] – Urtica involuta Steud., Nomencl. Bot. , ed. 2, 2: 735 (1841). – Macaranga View in CoL williamroxburghii Chakrab., Ann. Pl. Sci. 8: 3645 (2019), nom. illegit., superfl. – Type: W. Roxburgh s.n. (BM [BM000645881]).

Macaranga williamroxburghii Chakrab. is a superfluous renaming of Urtica involucrata Roxb. , as Steudel’s earlier replacement name, Urtica involuta , could legitimately be transferred to Macaranga . A proposal to conserve Urtica involucrata Roxb. , and hence maintain Macaranga involucrata as the correct name, has been published ( Turner, 2021b).

Macaranga peltata (Roxb.) Müll.Arg., Prodr. 15(2.2): 1010 (1866). – Osyris peltata Roxb., Fl. Ind. 3: 755–756 (1832). – Macaranga roxburghii Wall., J. Agric. Soc. View in CoL India 1: 14 (1842), nom. illegit., superfl. – Tanarius peltatus (Roxb.) Kuntze, Revis. Gen. Pl. View in CoL 2: 620 (1891).

Tanarius roxburghii Kuntze, Revis. Gen. Pl. View in CoL 2: 620 (1891), nom. illegit., superfl. – Type: India, W. Roxburgh 125 (lectotype BR [BR0000008494009], designated at the first step by Whitmore, Genus Macaranga View in CoL 203 [2008], and at the second step by Chakrabarty,

Ann. Pl. Sci. 8(10): 3635 [2019]; possible isolectotypes BR [ BR0000008493989 , BR0000008493996 , BR0000008494016 ] ).

Macaranga roxburghii Wall. is a superfluous renaming of Osyris peltata Roxb.

Magnolia pterocarpa Roxb., Pl. Coromandel View in CoL 3: 62–63, t. 266 (1820). – Liriodendron indicum Spreng., Syst. Veg. View in CoL , ed. 16, 2: 642 (1825), nom. illegit., superfl. – Type: W. Roxburgh s.n. (lectotype BM [000574745(BM)], designated here).

Talauma roxburghii G.Don, Gen. Hist. View in CoL 1: 85 (1831). – Type : India, Hortus Botanicus Calcuttensis, N. Wallich s.n. [ EIC 975.2 ] (lectotype K [ K000681437 ], designated here).

Liriodendron grandiflorum Roxb., Fl. Ind. View in CoL 2: 653 (1832). – Lirianthe grandiflora (Roxb.) Spach, Hist. Nat. Vég View in CoL 7: 485 (1838). – Magnolia sphenocarpa Wall. ex Steud., Nomencl. Bot. View in CoL , ed. 2, 2: 55, 90 (1841). – Type: W. Roxburgh s.n. (lectotype BM [000574745(BM)], designated here).

As the descriptions are almost identical, it is clear that Magnolia pterocarpa Roxb. View in CoL and Liriodendron grandiflorum Roxb. View in CoL apply to the same species. Presumably Robert Brown changed Roxburgh’s name in the process of editing the Plants of the Coast of Coromandel.

A Roxburgh specimen in BM is here designated lectotype of both names. George Don’s Talauma roxburghii clearly refers to the same species as well. There is a specimen in K labelled with Don’s name, although I think not in his hand. But Don may have seen it, and as there are no other specimens obviously representing original material, it is here designated as lectotype of Don’s name.
