Rhus chinensis Mill., Gard. Dict. (ed. 8): Rhus no. 7 (1768). – Type: Anon. s.n. (lectotype BM

De Candolle reduced Rhus amela D.Don to a variety of Rhus semialata , employing ‘roxburghii’ as the name for the variety.

Rinorea heteroclita (Roxb.) Craib, Fl. Siam. Enum. 89 (1925). – Vareca heteroclita Roxb., Fl. Ind. 2: 446-447 (1824). – Pentaloba roxburghii Wall., Numer. List n. 7189 (1832), nom. illegit., superfl. – Dioryktandra roxburghii Hassk., Retzia 125 (1855), nom. illegit., superfl.

Jarawa Tribe Andaman Isl. , India 78 [2020]). Figure 14.

Wallich set off a train of superfluous renamings with his publication of Pentaloba roxburghii .

Rivea ornata (Roxb.) Choisy, Mém. Soc. Phys. Genève 6: 409 (1834). – Lettsomia ornata Roxb., Fl. Ind. 2: 86 (1824). – Rivea roxburghii Prain ex Brandis, Indian Trees 484 (1906), nom. illegit., superfl. – Ipomoea ornata (Roxb.) J.R.I.Wood & Scotland, Nat.

Rivea roxburghii Prain ex Brandis is a superflous renaming of Lettsomia ornata Roxb. As no original herbarium material has been located, Roxburgh’s drawing is selected as lectotype here.

Trattinnick’s Rosa roxburghii replaces R. microphylla Roxb. ex Lindl. , an illegitimate later homonym.

Rotala rosea (Poir.) C.D.K.Cook ex H.Hara, Enum. Fl. Pl. Nepal 2: 173 (1979). – Ammannia rosea Poir. in Lamarck, Encycl., Suppl. 1: 329 (1810). – Type: Ind. Orientale, Anon. s.n. (lectotype FI [FI004320], designated by Cook, Boissiera 29: 86 [1979]).

Rotala roxburghiana Wight is a superfluous renaming of Ammannia pentandra Roxb.

Rourea minor (Gaertn.) Merr., Interpr. Herb. Amboin. 413 (1917). – Aegiceras minus Gaertn., Fruct. Sem. Pl. 1(1): 216, t. 46 in part (1788). – Type: Anon. s.n. (lectotype L [Carp. 1163], designated by Vidal, Fl. Cambodge, Laos, Vietnam 2: 36 [1962]).

Cnestis monadelpha Roxb. ex DC., Prodr. 2: 87 (1825). – Connarus roxburghii Hook. & Arn., Bot. Beechey Voy. 179 (1833), nom. illegit., superfl. – Rourea commutata Planch., Linnaea 23: 420 (1850), nom. illegit., superfl. – Santalodes monadelphum (Roxb. ex DC.) Kuntze, Revis. Gen. Pl. 1: 155 (1891). – Type: India, Botanic Garden Calcutta, vii 1818, N. Wallich s.n. (lectotype G-DC [IDC800 LM-295/8], designated here).

Rourea millettii Planch., Linnaea 23: 420 (1850). – Santalodes roxburghii Kuntze, Revis.

Gen. Pl. 1: 155 (1891), nom. illegit., superfl. – Type: China, C. Millett s.n. (lectotype K [ K000696000 ], designated here) .

Connarus roxburghii Hook. & Arn. represents a superfluous renaming of Cnestis monadelpha Roxb. ex DC. Planchon recognised this and renamed Connarus roxburghii as Rourea millettii excluding Hooker and Arnott’s synonyms. Nevertheless, these names are all synonyms of Rourea minor , a combination made by Merrill, considerably earlier than generally cited.
