Kalanchoe dyeri Brown (1904b: 354)

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 : 272

6. Kalanchoe dyeri Brown (1904b: 354) .

Type:— MALAWI, “ Anonymus s.n.”, as “ T ”, without further information, here corrected to lectotype, Herb. K, designated by Descoings (2003: 155).

Epitype:—[Nyasaland] MALAWI, received at the Royal Botanic Gardens, Kew, in 1902, specimen prepared on 2 May 1904, N.E. Brown s.n. (epitype, K barcode K232910 [image available at http://specimens.kew.org/herbarium/ K000232910]!), here designated.

Taxonomic notes:—At present K. dyeri is treated as an accepted species. The date of publication of the name K. dyeri is sometimes in error given as “1902” (see for example https://www.ipni.org/n/274325-1), likely because J. McClounie 35 was collected in September 1902. However, the species was only described in 1904.

Nomenclatural notes:—Herb. K holds two specimens of K. dyeri that predate description of the species on 4 June 1904. The first one, which consists of reproductive material only—intact inflorescence branches and flowers—is J. McClounie 35, dated September 1902 on the collecting label and 1903 on the herbarium label. Both these dates predate the description of K. dyeri in 1904. The material was collected in Northern Karonga, Panda [Mpanda] Peak in Malawi [“British Central Africa”] at an elevation of 6381 ft. [~ 1944 m]. The barcode of this specimen is K000285698 and it is accessible at http://specimens.kew.org/herbarium/K000285698.

The second specimen of K. dyeri held at Herb. K that predates description of this species on 4 June 1904 is N.E. Brown s.n. This specimen is dated 2 May 1904 and was therefore prepared one month before the species was described. The barcode of this material, which consists of both vegetative and reproductive material, is K232910, and it is accessible at http://specimens.kew.org/herbarium/K000232910. A month earlier, on 2 April 1904, the material was figured for inclusion in volume 60 [third series] of Curtis’s Botanical Magazine, with the painting and accompanying text eventually appearing later in the same year, as plate 7987 ( Brown 1904c: t. 7987).

Descoings (2003: 155) was the first to typify the name K. dyeri , which he did on a specimen referred to as “ T ” (see Eggli 2003: X for a definition of “ T ”) “ Malawi ( Anonymus s.n. [K])”. Since Brown (1904b: 354) did not cite any specimens in the protologue of the name and since, as discussed above, he clearly had more than one specimen at his disposal when publishing the name K. dyeri , this is interpreted as a lectotypification. The identity of this material [“ Malawi ( Anonymus s.n. [K])”] could not be determined and, in support of the lectotype, the name K. dyeri is here epitypified on the specimen N.E. Brown s.n., barcode K232910, which is accessible at http://specimens.kew.org/ herbarium/K000232910.
