3.3 Kalanchoe floribunda

The taxonomy and nomenclature of K.floribunda resolve as follows:

Kalanchoe floribunda Tulasne (1857: 150) , nom. illeg. ( Turland et al. 2018: Art. 53.1).

Type:—[ COMORO ISLANDS.] Iles Comores , Angazija, 1847–1852, M. [Louis-Hyacinthe] Boivin s.n. (lectotype P P00431004 , http://coldb.mnhn.fr/catalognumber/mnhn/p/p00431004), here designated as lectotype.

Notes on the lectotype:— In the protologue of the name K. floribunda, Tulasne (1857: 150) stated: “Crescit in planitie Angazijae Comorarum maioque floret (BOVINII [Boivin] Herb.).” [English: “It grows in the plains / flat areas of Angazija [Ngazidja / Grande Comore, Comoro Islands] and is very floriferous (the Herbarium of [Louis-Hyacinthe] Boivin.”).

Herb. P holds two specimens that bear printed labels with the wording: “Herb. Mus. Paris Iles Comores () M. Boivin 1847–1852. No.” that have the name “ Calanchoe [sic, Kalanchoe ] floribunda ”, along with reference to Tulasne (1857: 150), written on them in black ink. Both specimens are available for examination online. On the specimen with the barcode P00431003 (available at http://coldb.mnhn.fr/catalognumber/mnhn/p/p00431003), the place name “ Angazija ” was added between the round brackets, but this was not done on P00431004, where “ Angazija ” was rather written in black ink on a separate, folded paper capsule. The specimen with barcode P00431003 carries the date “mai, 1850” on a separate label, but the specimen with the barcode P00431004 is undated. In the upper left corner of the printed labels “1]” (on P00431003,) and “2]” (on P00431004) were added in pencil to the two specimens, but under Turland et al. (2018: Art. 8.3) there is no indication that this is a specimen mounted as two preparations. These two specimens are therefore syntypes.

The specimen with barcode P00431004 is more complete—it has vegetative and reproductive material attached to it—and is here designated as lectotype.

Taxonomic status of K. floribunda :—The illegitimate name K. floribunda Tulasne (1857: 150) is most often included in the synonymy of K. adelae or, perhaps somewhat counterintuitively, sometimes treated as a synonym of a broadly conceived K. lanceolata ( Forsskål 1775: CXI & 89) Persoon (1805: 446).
