3.1 Kalanchoe eriophylla

Kalanchoe eriophylla Hils. & Bojer ex Tulasne (1857: 149) .

Type:—[ MADAGASCAR.] Hab. in monte Antoungoun provinc. Emerinae., s.d., M. [W.] Bojer s.n. (holotype P P00374105 , http://coldb.mnhn.fr/catalognumber/mnhn/p/ p00374105) .

Heterotypic synonym:— Cotyledon pannosa Baker (1881:269) . Type:— MADAGASCAR. Ankaratra Mountains , 1879, L. Kitching s.n. (holotype K K000232849, http://specimens.kew.org/herbarium/K000232849, not seen).

Taxonomic status of K. eriophylla :— Kalanchoe eriophylla is an accepted species.

Notes on the holotype of the name K. eriophylla :—As part of the protologue of the name K. eriophylla, Tulasne (1857: 149) cites a single gathering, “ Provenit , BOJERIO docente, in monte Antoungoun provinciae Emirnensis (Herb. mus. par.)”. Boiteau & Allorge-Boiteau (1995: 168) state that the “ Type ” of the name K. eriophylla is “ Bojer s. no, Mt Antogona, Imerina. Holo-P.” Since there is a single specimen at Herb. P, MNHN-P-P00374105, we concur that this specimen is the holotype of the name K. eriophylla , under Turland et al. (2018: Art. 9.1). At Herb. BM a specimen annotated “ Madagascar. Hilsenberg and Bojer ” with the handwritten label “ Calanchoe eriophylla nob. Hab. in monte Antoongoon prov. Emerinae ” is likely part of the same gathering and is a better quality specimen than the one deposited at Herb. P, but in the absence of a collecting number or date it cannot be considered a duplicate of the holotype (isotype).

Notes on the type of the name Cotyledon pannosa :— Baker (1881: 269) seemingly did not cite any specimens in the protologue of the name C. pannosa . However , he clearly indicated ( Baker 1881: 264) that the collector was Langley Kitching (1835–1910) and that the collection was made in Madagascar in 1879. Kitching was in Madagascar from June to November 1879 ( Dorr 1997: 240–241). In the protologue, the locality of the collection is given as “Ankaratra mountains”.

Under the name C. pannosa, Herb. K holds the specimen L. Kitching s.n. [http://specimens.kew.org/herbarium/ K000232879], of which an image is not accessible online. Hamet (1908: 30 [46]) referred to the specimen, “ L. Kitching [s.n.]”, as “échantillon authentique” for the name C. pannosa , these two words are not equivalent to “type”; they only refer to a representative specimen and, in this case, also the only material cited by Baker (1881). Boiteau & Allorge-Boiteau (1995: 168) apparently overlooked Baker’s (and Hamet’s) reference to Kitching as the collector of the material cited in the protologue and erroneously state that, for the name C. pannosa , the “Type” is “s. nom de coll., massif de l’Ankaratra (prob. Baron 1032, iso-P)”, suggesting that a specimen of Baron 1032 might be the holotype, with an isotype extant at Herb. P. It is known that Baker was provided with large volumes of often undescribed plant material that was collected in Madagascar by Reverend Richard Baron (8 September 1847, Kendal , Westmorland , United Kingdom — 12 October 1907, Morecambe , Lancashire, United Kingdom) (see for example Smith & Figueiredo 2021: 195). Over a period of several years in the 1880s, Baker described many new genera and species represented by Baron’s specimens ( Smith & Figueiredo 2021, 2022b, 2023). Nevertheless , in this case there is no doubt that the original material of C. pannosa was collected by Kitching, and not by Baron , as is clearly stated by Baker (1881: 264).
