Typification of the infrageneric names published in Kalanchoe (Crassulaceae subfam. Kalanchooideae) by Alwin Berger
Phytotaxa, 2020Co-Authors: Gideon F. SmithAbstract:As part of the treatment of the Crassulaceae for Die natürlichen Pflanzenfamilien, Berger (1930: 402–408) published 10 named and numbered (“§ 1.” to “§ 10.”), but unranked groups in the genus Kalanchoe Adanson (1763: 248) sensu stricto. Berger (1930: 404–412) recognised Kalanchoe, Bryophyllum Salisbury (1805: t. 3), and Kitchingia Baker (1881: 268) as three separate genera. However, Berger (1930) did not subdivide Bryophyllum and Kitchingia into unranked groups. Rather, he restricted his infrageneric classification, of unranked “Gruppen”, to Kalanchoe sensu stricto, i.e., K. subg. Kalanchoe sensu Smith & Figueiredo (2018).

Kalanchoe crundallii i verd crassulaceae the chameleon Kalanchoe a little known south african endemic from the soutpansberg limpopo province with notes on its conservation status
Bradleya, 2019Co-Authors: Gideon F. Smith, Norbert HahnAbstract:The majority of the Kalanchoe species (Crassulaceae) that are indigenous to southern Africa have very wide natural geographical distribution ranges. Other Kalanchoes from the subcontinent, such as the recently described K. winteri Gideon F.Sm., N.R.Crouch & Mich.Walters that was recorded from the Wolkberg Centre of Endemism, are narrow endemics. Kalanchoe crundallii I.Verd. is one of the species with a restricted distribution range. Although it was for the first time collected in the 1930s, and described in the mid-1940s, the species remains little known. We provide an amplified description for, and discuss and illustrate, the species. Based on available evidence we propose the retention of a conservation status of Rare (see http://redlist.sanbi.org/redcat.php) for K. crundallii.

The nomenclature and correct author citation of the names Kalanchoe marnieriana H.Jacobsen ex L.Allorge and Bryophyllum marnierianum (H.Jacobsen ex L.Allorge) Govaerts (Crassulaceae), with notes on the nomenclature of some Madagascan Kalanchoe taxa
Bradleya, 2019Co-Authors: Gideon F. Smith, Estrela FigueiredoAbstract:It is shown that the correct author citation of the name Kalanchoe marnieriana (Crassulaceae) is “H.Jacobsen ex L.Allorge”, which was published in P. Boiteau & L. Allorge-Boiteau, Kalanchoe (Crassulacees) de Madagascar (1995: 102), as this replacement name for the illegitimate K. humbertiiMannoni & Boiteau (1947), non Guillaumin (1939), was only validly published by L.Allorge in 1995, and not by Jacobsen in 1954. If treated as a species of Bryophyllum Salisb., the correct author citation is B. marnierianum (H.Jacobsen ex L.Allorge) Govaerts. This often overlooked new combination in Bryophyllum was published by Govaerts in 1996. We also provide notes on the nomenclature and taxonomy of Madagascan taxa of Kalanchoe Adans. described in Boiteau & Allorge-Boiteau in 1995.

Aspects of the nomenclature of four names in Kalanchoe Adans. (Crassulaceae): Kalanchoe rosea C.B.Clarke, K. bouvieri Raym.-Hamet & H.Perrier, K. rosei Raym.-Hamet & H.Perrier, and K. rosea A.Chev.
Bradleya, 2019Co-Authors: Gideon F. Smith, Estrela FigueiredoAbstract:Aspects of the nomenclature of Kalanchoe rosea C.B.Clarke (1889), K. bouvieri Raym.- Hamet & H.Perrier (1912), K. rosei Raym.-Hamet & H.Perrier (1914), and K. rosea A.Chev. (1920) (Crassulaceae) are discussed and clarified. We argue that Kalanchoe rosea C.B.Clarke is a little known Indian species and that the name is not of unresolved application; that K. rosea A.Chev. (1920) that was published for a North African species is of unresolved application; and that the two validly published names K. bouvieri and K. rosei apply to the same Madagascan species, with the latter being a heterotypic synonym of the former. The name Kalanchoe rosea C.B.Clarke is lecto- and epitypified, and we show that the conditions for valid publication were met in the protologue of the later homonym K. rosea A.Chev.

Taxonomic and nomenclatural notes on Kalanchoe millotii Raym.-Hamet & H.Perrier and the cultivar Kalanchoe ‘Fern Leaf’ (Crassulaceae)
Bradleya, 2019Co-Authors: Gideon F. Smith, Estrela FigueiredoAbstract:The taxonomy of, and nomenclature applicable to, Kalanchoe millotii Raym.-Hamet & H.Perrier (Crassulaceae) are discussed with special reference to the typification of this name. A previous claim that the name has a holotype is incorrect. The name K. millotii is [second-step] lectotypified on a specimen, [J.M.H.A.] Perrier [de la Bâthie] 11789, barcode P P00374225, held in Herb. P. An amplified description is provided for this distinctive Madagascan species. The early history of the cultivar Kalanchoe ‘Fern Leaf’ is also discussed and clarified. This cultivar was selected from hybrid offspring raised at Hummel's Exotic Gardens of southern California; the parent stock was given as K. beharensis Drake and K. millotii.

Kalanchoe in Southern Africa
Kalanchoe (Crassulaceae) in Southern Africa, 2019Co-Authors: Gideon F. Smith, Estrela Figueiredo, Abraham E. Van WykAbstract:Abstract The history of Kalanchoe discovery including the taxonomic history of the genus in southern Africa is discussed. Important collectors and researchers on Kalanchoe and their contributions to the taxonomy of the group in, especially, southern Africa are highlighted. These researchers include William H. Harvey, Selmar Schonland, Raymond-Hamet, R. Harold Compton, Rosette Batarda Fernandes, Hellmut R. Toelken, and, more recently, Neil R. Crouch. Reference is made to botanical works of art with southern African Kalanchoe species as subject, especially plates of those that appeared in The flowering plants of South Africa and (The) (F-)flowering plants of Africa. The number of southern African species of Kalanchoe is noted. The common names recorded for, and applied to, the Kalanchoes of southern Africa are comprehensively tabulated and briefly discussed. Common names used for, or associated with, particular species are given in the taxonomic treatments of those species.

The taxonomy and type of Kalanchoe sexangularis N.E.Br. (Crassulaceae)
Bradleya, 2016Co-Authors: Estrela Figueiredo, Gideon F. Smith, Neil R. CrouchAbstract:The taxonomy of Kalanchoe sexangularis N.E.Br. (Crassulaceae), a common southern Africa species, is clarified. We interpret K. sexangularis as consisting of two varieties, K. sexangularis var. sexangularis and K. sexangularis var. intermedia (R.Fern.) R.Fern. An amplified description is provided for the species and differences between the two varieties are noted. The type specimen, Thorncroft s.n. (K, holo-), which is to be associated with Kalanchoe sexangularis var. sexangularis, is established.

Bufadienolides of Kalanchoe species: an overview of chemical structure, biological activity and prospects for pharmacological use
Phytochemistry Reviews, 2017Co-Authors: Joanna Kolodziejczyk-czepas, Anna StochmalAbstract:Toad venom is regarded as the main source of bufadienolides; however, synthesis of these substances takes also place in a variety of other animal and plant organisms, including ethnomedicinal plants of the Kalanchoe genus. Chemically, bufadienolides are a group of polyhydroxy C-24 steroids and their glycosides, containing a six-membered lactone (α-pyrone) ring at the C-17β position. From the pharmacological point of view, bufadienolides might be a promising group of steroid hormones with cardioactive properties and anticancer activity. Most of the literature concerns bufadienolides of animal origin; however, the medicinal use of these compounds remains limited by their narrow therapeutic index and the risk of development of cardiotoxic effects. On the other hand, plants such as Kalanchoe are also a source of bufadienolides. Kalanchoe pinnata (life plant, air plant, cathedral bells), Kalanchoe daigremontiana (mother of thousands) and other Kalanchoe species are valuable herbs in traditional medicine of Asia and Africa. The present review focuses on the available data on chemical structures of 31 compounds, biological properties and prospects for therapeutic use of bufadienolides from Kalanchoe species. Furthermore, it presents some new investigational trends in research on curative uses of these substances.
