Smith, Gideon F., 2023, A nomenclatural and taxonomic review of the names and new combination published between 1886 and 1931 in Kalanchoe (Crassulaceae subfam. Kalanchooideae) by British botanist Nicholas Edward Brown (1849 - 1934), Phytotaxa 630 (4), pp. 266-280 : 270

2. Kalanchoe × kewensis Brown (1902a [14 June]: 387) ,

non K. × kewensis Watson (1902 [24 May]: 338–339).

Type:— GREAT BRITAIN. Royal Botanic Gardens, Kew, ex hort., June 1902, N.E. Brown s.n., (lectotype, a twopreparation specimen, K barcode K000838472 [image available at http://specimens.kew.org/herbarium/K000838472]! and K barcode K000838473 [image available at and http://specimens.kew.org/herbarium/K000838473]!), designated by Smith (2023c: 277).

Taxonomic notes:—The name K. × kewensis Brown (1902a [14 June]: 387) is an illegitimate later homonym of K. × kewensis Watson (1902 [24 May]: 338–339) ( Fig. 1C ) ( Turland et al. 2018: Art. 53.1, Rec. 50C.1). Thiselton-Dyer (1903), Smith & Shtein (2021), Heijnsdijk (2022), Smith (2022a), and Smith (2023c: 277–279) provide additional information on this nothospecies that was created in cultivation at the Royal Botanic Gardens, Kew. Kalanchoe × kewensis has been available near-globally in the horticultural trade for more than 120 years.

Nomenclatural notes:—The typification of the name K. × kewensis was dealt with comprehensively elsewhere ( Smith 2023c: 277).

FIGURE 1. A–B. Two Kew botanists appointed in the 1860s and 1870s, in sequence: A. John Gilbert Baker (1834–1920) and B. Nicholas Edward Brown (1849–1934). C–G. A selection of species described in Kalanchoe by N.E. Brown. Where necessary, the nomenclature reflects the currently accepted names of the taxa. C. Kalanchoe ×kewensis N.E.Br., non K. ×kewensis W.Watson, an illegitimate homonym (see text for a discussion). D. Kalanchoe lateritia is the accepted name of K. kirkii. E. Kalanchoe lanceolata is the accepted name of both K. diversa and K. ellacombei. F. Kalanchoe prasina is an accepted species. G. Kalanchoe sexangularis is an accepted species. H. Elise [Eliza] Keller (1869–1944), the wife of the botanist Alwin Berger (1871–1931), is commemorated in K. elizae, the currently accepted name of K. insignis. Kalanchoe elizae was the first name published in Kalanchoe to honour a woman. The name was published in January 1903 by Berger, four months before he and Keller got married. The photograph reproduced here was taken in 1935 while Elise was visiting her son, Fritz, in Pasadena, U.S.A. Photograph credits: A. Photographer unknown.
