TABLE 4 in A review of the infrageneric classifications proposed for Kalanchoe (Crassulaceae subfam. Kalanchooideae) from the earliest times up to 2000

TABLE 4. Infrageneric classification, as unnamed “groupes”, of Kalanchoe according to Hamet (1907a: 877–879, 1908a, b, 1910a, b). The species-rank nomenclature that Hamet used in these publications is deliberately retained. For each group all the species names included by Hamet are listed. “ K.” = Kalanchoe.

1 Kalanchoe porphyrocalyx, K. schizophylla, and K. sulphurea were included in Group 1, each with a question mark, as they were treated as “Species non satis notae”; see Hamet (1907a: 877) and Hamet (1908a: 41–42).
2 Kalanchoe trichantha (Group 6) is widely regarded as a synonym of K. synsepala, in turn the only species included in Group 4 (Hamet 1912c).
3 Kalanchoe abrupta is widely regarded as a synonym of K. robusta Balfour filius (1882: 512). Kalanchoe abrupta was accepted by Hamet (1907a: 888), but he treated K. robusta as a little known species [“Species non satis notae”]. Still, under K. abrupta, Hamet (1907a: 888) stated: “Observation: Par une erreur de typographie la diagnose du K. abrupta est donnée dans le Botany of Socotra sous le nom de K. robusta, et vice-versa.” [English: “Observation: In the Botany of Socotra, through a typographical error, the diagnosis of K. abrupta is given under the name of K. robusta, and vice versa”. The paper entitled “ Botany of Socotra ” (Balfour 1888) was published six years after Balfour (1882) appeared in print.
4 Kalanchoe farinacea is endemic to Socotra only. The species endemic to Angola with which it was confused by Hamet (1907a, 1908a) is K. scapigera Welwitsch (1871d: 397) (see Figueiredo & Smith 2020: 94 and Smith & Figueiredo 2020a).
5 Kalanchoe thyrsiflora, the only other Kalanchoe species with soup plate-sized leaves and dense-flowered, somewhat club-shaped inflorescences known at the time, and a close relative of K. luciae (Smith & Figueiredo 2018c, Smith 2020d), was included in Group 13 by Raymond-Hamet. However, Berger (1930: 404, 407) transferred K. thyrsiflora to his [Berger’s] unranked group “§ 8. Transvaalenses”. Kalanchoe luciae was originally included as the only species in the numbered but unnamed “Groupe 14” of Hamet (1908b: 254, 256–257). This group was previously treated as K. subg. Fernandesiae (Smith 2020d) or, most recently, as K. sect. Raveta Smith (2022a: 210), depending on which taxonomic rank is preferred.
