Kalanchoe latisepala Brown (1908: 435)

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 : 273

9. Kalanchoe latisepala Brown (1908: 435) .

Type:—[Tropical Africa, Nyasaland] MALAWI, “raised from seed sent by Mr. J. McClounie to Kew in 1905, flowered in March, 1907”, specimen prepared on 22 March 1907, J. McClounie s.n. (holotype, K barcode K232911 [image available at http://specimens.kew.org/herbarium/K000232911]!).

Taxonomic notes:— Kalanchoe latisepala is an accepted species (see Descoings 2003: 162).

Nomenclatural notes:—When publishing the name K. latisepala, Brown (1908: 435) cited a single specimen, “ Mr J. McClounie ”—the convention followed in the paper was to place the specimen citation in italics—with information associated with this specimen being: “TROPICAL AFRICA. Nyasaland; raised from seed sent by Mr. J. McClounie to Kew in 1905, flowered in March, 1907.” The specimen itself was prepared on 22 March 1907. This is the only specimen cited by Brown (1908: 435) and there is no evidence that duplicates of it exist, or that he had additional material available when he published the name K. latisepala . It is therefore the holotype of the name K. latisepala .

Descoings (2003: 162) attempted a typification of the name K. latisepala . As “ T ” he proposed a specimen referred to as “ Malawi ( Anonymus s.n. [K])”. The convention followed in Descoings (2003) is that “ T ” refers to the “(nomenclatural) type” ( Eggli 2003: X). This, presumably, lectotypification on a specimen different from the one cited in the protologue was superfluous because the name K. latisepala has a holotype.
