Kalanchoe globulifera, , Perrier de la Bathie, 1928

Smith, Gideon F., 2023, Nomenclatural notes on Kalanchoe globulifera (Crassulaceae subfam. Kalanchooideae), the species under which the economically important K. blossfeldiana was at first recognised, at the rank of variety, as K. globulifera var. coccinea, Phytotaxa 619 (1), pp. 111-111 : 111

Typification of the name Kalanchoe globulifera

For K. globulifera, Boiteau & Allorge-Boiteau (1995: 187) stated: “TYPE: Perrier 16222 bis, jardin Tananarive, provenance rocailles vers 2000 m, Mt Tsaratanana, [Herb.] P.” This was an effective lectotypification of the name K. globulifera on [J.M.] H. [A.] Perrier de la Bâthie 16222 bis. “TYPE” is here corrected to lectotype (see below) and, because this gathering consists of three specimens, in a second-step lectotypification, the lectotypification of Boiteau & Allorge-Boiteau (1995: 187) is narrowed down to one of the Herb. P specimens.

The nomenclature and typification of the name K. globulifera resolve as follows:

Kalanchoe globulifera Perrier de la Bâthie (1928: 25) .

Type:— MADAGASCAR. Northern Madagascar. Southern slopes of Mount Tsaratanana, on more or less shaded rocks (gneiss), or on the trunks of trees or shrubs, often among the mosses, in rather dense and always very homogeneous stands, around 2400 m above sea level [translated from the original French], no date, [J.M.] H. [A.] Perrier de la Bâthie 16222 bis (here corrected to lectotype, from “TYPE”, the latter having been the interpretation of Boiteau & Allorge-Boiteau (1995: 187), P barcode P00374107 ! [Image available at http://coldb.mnhn.fr/catalognumber/mnhn/p/ p00374107]), second-step lectotype here designated ( Fig. 2 ) .

Homotypic synonyms:—None recorded.

Nomenclatural notes:— Eight years after Boiteau & Allorge-Boiteau (1995: 187) effectively (lecto-)typified the name K. globulifera, Descoings (2003: 157) stated: “ T: Madagascar (Perrier 16222 [P])” and, in so doing, referenced the other, second gathering cited by Perrier de la Bâthie (1928: 25) as the type, with the abbreviation “ T ” defined as “(nomenclatural) type ” in Eggli (2003: X). However, this attempted retypification has no status because the earlier typification of Boiteau & Allorge-Boiteau (1995: 187) was effective and must stand ( Turland et al. 2018: Art. 9.19).

The place where, if at all, Perrier de la Bâthie (1928) published the designation “ Kalanchoe globulifera var. typica ” that Boiteau & Allorge-Boiteau (1995: 187 and in the “Index des noms scientifiques”, on p. 245) cited, as “ K. globulifera var. typica Perrier , loc. cit. [i.e., Perrier de la Bâthie (1928: 25)]”, could not be traced. As far as could be determined, reference to “[ Kalanchoe globulifera ] var. typica ” was only made in sched. on Perrier de la Bâthie’s handwritten collecting labels on the Herb. P specimens with barcodes P00374108 and P00431202, and not in print. Descoings (2003: 157) ascribed “ K. globulifera var. typica ” to Boiteau & Allorge-Boiteau (1995) and noted that it was not validly published (see Turland et al. 2018: Art. 24.3 on use of the final epithet ‘ typicus ’). However, it does not seem that Boiteau & Allorge-Boiteau (1995: 187) published the designation “ K. globulifera var. typica ”. Boiteau & Allorge-Boiteau (1995: 187) rather referenced Perrier de la Bâthie as having done so, which he did not. If Boiteau & Allorge-Boiteau (1995: 187) indeed intended it as a new ‘name’, it was additionally not validly published because it lacked a Latin description ( Turland et al. 2018: Art. 39.1). Also, this ‘name’ was merely listed as a synonym and therefore additionally not validly published ( Turland et al. 2018: Art. 36.1(b )).

Descoings (2003: 157) further referenced “ Kalanchoe globulifera var. blossfeldiana Boiteau ex Allorge-Boiteau (1995) ” as having been not validly published. This designation is listed only in the “Index des noms scientifiques”, on p. 245 of Boiteau & Allorge-Boiteau (1995), but does not appear on p. 190 of Boiteau & Allorge-Boiteau (1995) as stated in the “Index des noms scientifiques”.
