Crossostylis multiflora Brongniart & Gris. At 1861
No full textCrossostylis multiflora Brongniart & Gris (1861a: 378). Haplopetalon multiflorum (Brongn. & Gris) Baillon (1862: 40) as ‘Haplopetalum multiflorum’. Lectotype (designated here):— NEW CALEDONIA, Balade, 1855–1860, Vieillard 43 (P00402853!). The name Crossostylis multiflora was validly published by Brongniart & Gris (1861a) in a footnote added in press with the citation of a specimen, Vieillard 43, and a comparison with C. biflora and C. grandiflora, which can be considered as a diagnosis. It was therefore already a valid name when Sebert & Pancher (1874) published a description of the species. Only one sheet of this number at P appears to bear Brongniart’s original handwriting and it is treated here as the lectotype (P00402853!). Another sheet of Vieillard 43 (P05574280!), has a different locality (Wagap) and cannot be considered as an isolectotype.Published as part of Pillon, Yohan, 2023, Taxonomic notes on New Caledonian Malpighiales: Acridocarpus, Crossostylis, Erythroxylum, and Xylosma, pp. 207-212 in Phytotaxa 583 (2) on page 208, DOI: 10.11646/phytotaxa.583.2.9, http://zenodo.org/record/760936
Xylosma zongoi Pillon 2023, nom. nov.
No full textXylosma zongoi Pillon nom. nov. (LSID: 77312126-1). Replaced synonym: Lasiochlamys coriacea Sleumer (1974: 126). Type:— NEW CALEDONIA, Pouébo: Mont Mandjélia (exploitation forestière Frouin), 600–700 m, 4 June 1971, MacKee 24594 (holo-: P00648821!, iso-: L0011078!, NOU005995!). Non Xylosma coriacea (Poiteau) Eichler (1871: 449). Non Xylosma coriacea Lignier & Bey (1904: 167) nomen nudum. Non Xylosma coriacea Pancher ex Guillaumin (1919: 313) nomen nudum. The combination in Xylosma in pre-empted by three earlier names. The new epithet chosen commemorates Charly Zongo (1980–2015), for his contribution to our knowledge on the seed physiology of New Caledonian plants (Bombarda et al. 2010; Zongo 2010; Zongo et al. 2016).Published as part of Pillon, Yohan, 2023, Taxonomic notes on New Caledonian Malpighiales: Acridocarpus, Crossostylis, Erythroxylum, and Xylosma, pp. 207-212 in Phytotaxa 583 (2) on page 210, DOI: 10.11646/phytotaxa.583.2.9, http://zenodo.org/record/760936
Acridocarpus
No full textACRIDOCARPUS (MALPIGHIACEAE) Acridocarpus austrocaledonicus Baillon (1874: 248) Lectotype (designated here):— NEW CALEDONIA, versant méridional du Montd’Or, 17 May 1969, Balansa 1475 (P00130332!, iso-: P00537785!, P00537786!). Remaining syntypes: Koé, 14 December 1968, Balansa 1039 (P00130334!, P00537783!, P00537784!), Bai Lebris, December 1868, Balansa 1688 (P00130335!), s.loc., s.dat., Pancher 151 (P00130333!, P05529966!, P05529968!, P05529969!). Acridocarpus alexandrinae Niedenzu (1928: 262) nomen nud. When he described Acridocarpus austrocaledonicus, Baillon (1874) cited several collections (syntypes): Balansa (1039, 1475, 1688), Vieillard (s.n.) and Pancher (s.n.). One sheet of Balansa 1475 (P00130332!), with Baillon’s handwriting, is chosen here as the lectotype. Niedenzu (1928) attributed the unpublished name Acridocarpus alexandrinae to Planchon, but this name was probably first coined by Pancher (written by hand on Vieillard 249, P05529955!, P05529958!).Published as part of Pillon, Yohan, 2023, Taxonomic notes on New Caledonian Malpighiales: Acridocarpus, Crossostylis, Erythroxylum, and Xylosma, pp. 207-212 in Phytotaxa 583 (2) on page 207, DOI: 10.11646/phytotaxa.583.2.9, http://zenodo.org/record/760936
