Turner, Ian M., 2022, FROM ACACIA TO ZIZIPHUS: PLANT NAMES COMMEMORATING THE BOTANIST WILLIAM ROXBURGH, Edinburgh Journal of Botany 79 (1911), pp. 1-102 : 42-45

Cyperus laevigatus L., Mant. Pl. 2: 179 (1771). – Type: Anon. s.n. [ J. G. Koenig] (lectotype

LINN [LINN-HL 70.13], designated by Tucker & McVaugh in McVaugh, Fl. Novo-Galiciana 13: 308 [1993]).

Cyperus roxburghianus C.Presl, Isis (Oken) 21: 272 (1828). – Type: [unpublished illustration] Icones Roxburghianae 704 (lectotype K, designated here).

Cyperus roxburghii A.Dietr., Sp. Pl. , ed. 6, 2: 214 (1833). – Type: Anon. s.n. [J.G. Koenig] (lectotype LD [ LD1293107 ], designated here).

Karl Presl published Cyperus roxburghianus as a new name for Cyperus mucronatus Roxb. , non Rottb. Roxburgh’s drawing is here designated as lectotype. Albert Dietrich also commemorated Roxburgh in providing a name for Roxburgh’s plant, also including Retzius’s plant. A lectotype is designated here following Fischer’s designation for Cyperus mucronatus Retz. , non Rottb.

Cyperus paniceus (Rottb.) Boeckeler, Linnaea 36: 381 (1870). – Kyllinga panicea Rottb., Descr. Icon. Rar. Pl. 15, t. 4, f. 1 (1773). – Type: J.G. Koenig s.n. (lectotype C [ C10010287 ], designated here).

Mariscus paniceus var. roxburghianus C.B.Clarke in Hooker, Fl. Brit. Ind. 6(19): 621 (1893).

– Mariscus roxburghianus (C.B.Clarke) Alston , in Trimen, Handb. Fl. Ceylon 6(Suppl.):

309 (1931). – Cyperus paniceus var. roxburghianus (C.B.Clarke) Kük. in Engler, Pflanzenr. IV, 20(101): 526 (1936). – Type: Hb. Madr. s.n. [ EIC 3434 ] (lectotype K-W [ K001119367 ], designated here) .

Clarke based his var. roxburghianus on material from the Wallich Herbarium. One of the sheets in K-W is here selected as lectotype. Also, a Koenig specimen in C is designated for Kyllinga panicea Rottb.

Cyperus platyphyllus Roem. & Schult., Syst. Veg. , ed. 15 bis, 2: 876 (1817). – Papyrus latifolius Willd., Abh. Königl. Akad. Wiss. Berlin 1812 –1813: 74 (1812). – Type: J.G. Klein 979c (lectotype B-W [B - W 01417 -01 0], designated here).

Cyperus roxburghii Nees in Wight , Contr. Bot. India 84 (1834), nom. illegit., non C. roxburghii A.Dietr. (1833) . – Type: non designatus.

Nees based Cyperus roxburghii on a Wight collection and Cyperus elatus sensu Roxburgh. I have not traced any original material so leave the typification unresolved. A specimen from B-W is designated as lectotype of Papyrus latifolius Willd.

Dendrobium calceolum Roxb., Fl. Ind. 3: 488 (1832). – Aporum roxburghii Griff., Calcutta J. Nat. Hist. 4: 370 (1845), nom. illegit., superfl. – Dendrobium roxburghii Lindl., J. Proc. Linn. Soc., Bot. 3: 4 (1858), nom. illegit., superfl. – Type: [unpublished illustration] Icones Roxburghianae 1651 (lectotype K, designated here). Figure 8 .

Griffith renamed Dendrobium calceolum Roxb. as Aporum roxburghii . The change of epithet was not required, so the name is illegitimate. Roxburgh’s drawing at Kew is here selected as lectotype for Dendrobium calceolum as no herbarium material has been located.

Dicliptera chinensis (L.) Juss., Ann. Mus . Hist. Nat. 9: 268 (1807). – Justicia chinensis L., Sp. Pl. 1: 16 (1753). – Type: Anon. s.n. (lectotype LINN [LINN-HL 28.19], designated by Hara, J. Jap. Bot. 55: 324 [1980]).

Dicliptera roxburghiana Nees in Wallich, Pl. Asiat. Rar. 3: 111 (1832). – Type: India, Botanical Garden [Calcutta], 29 xi 1814, F. Buchanan-Hamilton s.n. [ EIC 2466 A] (lectotype GZU [ GZU000249877 ], designated here; isolectotype K-W [ K001116138 ]).

A lectotype is designated for Dicliptera roxburghiana Nees. A specimen from GZU that contains material from Nees’s herbarium is selected.

Digitalis roxburghii Roth , Nov. Pl. Sp. 283 (1821). – Type: India, B. Heyne s.n. (n.v.).

The identity of Roth’s Digitalis roxburghii remains uncertain ( Turner, 2021a).

Digitaria longiflora (Retz.) Pers., Syn. Pl. 1: 85 (1805). – Paspalum longiflorum Retz., Observ. Bot. 4: 15 (1786). – Type: J.G. König s.n. (lectotype LD [LD1739033], designated by Henrard, Monogr. Gen. Digitaria 410 [1950]; possible isolectotypes BM, K).

Milium filiforme Roxb., Fl. Ind. 1: 316–317 (1820), nom. illegit., non M. filiforme Lag. (1816) . – Paspalum nematodes Schult.f., Mant. 2: 171 (1824) [i–iv 1824]. – Digitaria roxburghii Spreng., Syst. Veg. 1: 270 (1824) [late 1824], nom. illegit., superfl. – Paspalum bifarium Edgew., J. Asiat. Soc. Bengal 21: 157 (1852), nom. illegit., superfl. – Type: India Orientalis, W. Roxburgh s.n (lectotype BM [BM000959638], designated by Veldkamp, Blumea 21: 67 [1973]).

Digitaria roxburghii is a name proposed by Sprengel to replace Roxburgh’s later homonym Milium filiforme . However, Schultes had already published a nomen novum, making Sprengel’s name superfluous.

Dimeria avenacea (Retz.) C.E.C.Fisch., Bull. Misc. Inform. Kew 1932: 72 (1932). – Anthoxanthum avenaceum Retz., Observ. Bot. 3: 8 (1783). – Heteropogon roxburghii Arn. ex Nees , Nov. Actorum Acad. Caes. Leop.-Carol. Nat. Cur. 19(Suppl. 1): 183 (1843), nom. illegit., superfl. – Type: J.G. Koenig s.n. (lectotype LD [LD1213217], designated by Fischer, Bull. Misc. Inform. Kew 1932: 72 [1932]).

Heteropogon roxburghii Arn. ex Nees is a superfluous renaming of Anthoxanthum avenaceum Retz.
