Kalanchoe tubiflora (Harv.) Hamet (1912: 44)

Smith, Gideon F. & Figueiredo, Estrela, 2023, Names validly published in Kalanchoe (Crassulaceae subfam. Kalanchooideae) by Louis-René ‘ Edmond’ Tulasne in 1857, with reference to names proposed in sched. by Hilsenberg and Bojer for two Malagasy species, and with notes on the type of the name K. tubiflora, Phytotaxa 584 (4), pp. 275-284 : 280-281

The nomenclature of K. tubiflora was discussed by Figueiredo & Smith (2017: 771).

Kalanchoe tubiflora (Harv.) Hamet (1912: 44) ( Fig. 2 ).

Type:—[MOZAMBIQUE or, possibly, MADAGASCAR]. s.l. s.d., s.c. / leg. ign. s.n. (holotype S S-G-10717 , https://herbarium.nrm.se/specimens/S-G-10717/image/) .

Basionym:— Bryophyllum tubiflorum Harvey (1862: 380) .

Note on the holotype:—In the protologue of the basionym of this species, Harvey (1862: 380) cited a single collection made by John Forbes in Delagoa Bay , a region today regarded as the area around Maputo in southern Mozambique. Harvey (1862) added that the collection was kept at the Sonder Herbarium. This refers to the same collection that was earlier cited by Ecklon & Zeyher (1837) as being a single and mutilated example (“exemplum unicum et mutilum”) of K. delagoensis Ecklon & Zeyher (1837: 305) collected and presented by “Cel Commodore Owen”, i.e. Capt. William Fitz William Owen. Herb. S acquired the major part of the South African, i.e., Flora capensis, herbarium of Sonder. The specimen cited by Ecklon & Zeyher (1837: 305) and by Harvey (1862: 380) is kept at Herb. S (S-G-10717), it consists of two flowers and a stem fragment and it has no label information. The plant could have originated from Madagascar where Owen’s expedition called, and could have been collected by Owen or Forbes (see Figueiredo & Smith 2022).

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

FIGURE 2. Kalanchoe tubiflora. The type specimen of the name K. tubiflora was collected in Mozambique or, possibly, in Madagascar, by either William Fitz William Owen or by John Forbes (see main text for a discussion). A. Plants in the vegetative growing phase. B. Partial inflorescences developing late in the (winter) flowering season. The species is known to have invasive tendencies and easily becomes established in places well away from its natural geographical distribution range in southern Madagascar (see Shtein et al. 2021: 250, Fig. 9).
