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.
