Kalanchoe

Bonsoir

J'ai eu un coup de coeur pour ce Kalanchoe

Quelqu'un aurait-il une idée quant à son nom?
Merci!

Re: Kalanchoe

Je ne trouve pas la description de x richaudii, mais la plante que j'ai pu voir chez Richaud a des feuilles plus linéaires et pas aussi franchement dentées, comme on peut le voir sur la plante de Perle.
Nous sommes bien en présence d'une des nombreuses formes ou hybrides (naturels ou pas) de K. rosei, mais je n'en sais pas plus, ni même si le nom 'Lucky Bells' a fait l'objet d'une publication.
Perle, peut-être devrais-tu demander l'avis de Philippe Richaud.

Re: Kalanchoe

J'ai la même plante et Sven Bernhard l'a identifié comme K. x richaudii.

Re: Kalanchoe

Sorry for using English here,

I agree with Tom and Lur - this plant is K. rosei var variifolia (var according to Shaw), and it is distributed under the cultivar name 'Lucky Bells' in Europe. As Tom said it differs from K. x richaudii in much bigger and pronounced teeth and less linear leaves, but also by being petiolate (mature leaves of course) while K. x richaudii is sessile. variifolia also has a very different calyx - remains green with spots between sepals in sun (not purple in sun or just green in shade like x richaudii), with calyx tube that is shorter and much widest at the base of the sepals (not longer and nearly tubular/cylindrical in x richaudii), and with more acute sepals than x richaudii. Shaw (2008) included in this name K. "rauhii" too, saying that they are the same, without justification.

K. rosei var variifolia, "rauhii" and x richaudii are all hybrids of rosei (var rosei and/or serratifolia), most likely with delagoensis (also some suggested daigremontiana as the second parent for variifolia, but without justification). So the name x richaudii is definitely more appropriate than K. rosei var variifolia, but this is not proven to be true (that variifolia is also rosei x delagoensis) - so I would not call this plant x richaudii, especially as it looks very different from the "real" x richaudii. ("rauhii", that possibly represents the same plant as variifolia, is an invalid name - so it is not a viable option either).
