K as early as January 1908, with the (living) material grown at Kew and a (preserved) specimen deposited on 10 April 1908, Georges Bouvet s.n. (lectotype Herb. K barcode K 000232789), image available at https://data.kew.org/records/occurrences/search?q=lsid:urn:lsid: ipni.org:names:274508-1#tab_recordImages, designated by Smith (2024b: 68).

Heterotypic synonyms:— Kalanchoe ambrensis Perrier de la Bâthie (1928: 23 [see also p. 30]);

Bryophyllum ambrense (H.Perrier) Berger (1930: 412) .

Type of the name Kalanchoe ambrense and its homotypic synonym, Bryophyllum ambrense :— MADAGASCAR.Central-north Madagascar, Ambre massif [Montagne D’Ambre, Amber Mountains], between altitudes of 1000 and 1400 m, flowers bright purple, September 1926, [ J. M.] H.[ A.] Perrier de la Bâthie 17735 (corrected to lectotype from holotype, by Smith 2024b: 68, ‘holotype’ having been the interpretation of Boiteau & Allorge-Boiteau (1995: 81), Herb. P barcode P 00374201!), image available for examination online at http://coldb.mnhn.fr/catalognumber/mnhn/p/p00374201, second-step lectotype designated by Smith (2024b: 68).

Designations not validly published:—“ Kalanchoe uniflora var. typica ” Boiteau & Manonni (1949: 9), nom. inval. ( Turland et al. 2018: Art. 24.3).

“ Kalanchoe uniflora var. brachycalyx ” Boiteau & Manonni (1949: 9), nom. inval. ( Turland et al. 2018: Art. 39.1).

Nomenclatural notes:—The attempted typification of the name Kitchingia uniflora on the plate included in Stapf (1909: t. 8286) by Boiteau & Allorge-Boiteau (1995: 81) was not effective. This not effective typification was repeated by Descoings (2003: 178), as “ T: [icono]: Curtis’s Bot. Mag. 135: t.8286, 1909”, with “ T: ” being the “(nomenclatural) type ” ( Eggli 2003: X). The typification of the name Kitchingia uniflora , basionym of Kalanchoe uniflora , was dealt with by Smith (2024b: 68).

Taxonomic notes:— Kalanchoe uniflora is an accepted species (see Boiteau & Allorge-Boiteau 1995: 81–82, Descoings 2003: 178–179, and Smith et al. 2021c: 255–257).

Kalanchoe uniflora is included in Kalanchoe subg. Alatae .
