What is this plant (Crassulaceae)

Factual Questions
1

I have a potted plant that looks like this

http://toptropicals.com/pics/garden/m1/succulent/Aeonium_sp826.jpg

but has both the inflorescence and the stolons borne on a long petiole (a foot and a half or 30-40 cm); the stolons, arising from the base of the leaf, bear a plantlet with roots. The succulent green leaves (4 " or 10 cm wide) are dentate, edged with reddish brown.

Some species of Aeonium apparently. Common name might be harder to track down.

I googled Aeonium but didn’t find anything with those characteristic and showy stolons.

It am 99.5% certain that your plant is Aeonium ‘Kiwi’ and 100% sure that it is an Aeonium of some sort. (The url of your link even includes the word “Aeonium”.) It is often hard to find pictures of a plant in exactly the stage of growth that you want. I own a couple of these and have never seen them in bloom.

Too late to edit: I should say, the plant in the example you posted is definitely an Aeonium. Since you didn’t post a picture of your actual plant, that is all I have to go on.

Belongs to the Saxifragales , sensu APG II. The Crassulaceae is the stonecrop family with 33 genera and about 1500 species. To track down the species name might take some time, but I can check if I can get some more info :slight_smile:
What sort of inflorescence is it? Branched cyme or solitary flowers?
Are the flowers sessile or pedicellate?
How many calyx does it have?
How many corolla?
How many stamens are there? Are they biseriate and obdiplostemonous or uniseriate and antisepalous?

Here is an amazing website: Angiosperm Phylogeny Website
Once there, look under saxifragales on the sidebar.

I’ll keep looking :slight_smile:

Sorry for the double post, but is this a close estimate?

It’s night at this time in Switzerland, so I had to get out with flashlight and magnifier to see the details. The flowers are a dichotomous cyme, pedicellate, at the tip of that long stolon. The flowers are faded now but I can see they have 4 sepals and seemingly 6 stamens (I don’t know the other technical terms you mention). The spread of the plant is almost 4 feet (120 cm).

I did check the Davarree and other sites before I posted but I couldn’t find any photos showing those amazing stolons. My plant is quite close the hybrid pictured there though the leaves are not so finely serrated.

It’s definitely an Aeonium like Monstera says, and perhaps also a hybrid. I’ll keep searching untill I find a description. I’m familiar with the APG. Truly fascinating.

I got the plant from a botanical garden in Madagascar but I don’t know if it’s native there.

Many thanks

I asked my professor, a phylogenetics guy, and basically he tossed his hands in the air, and gave me a very long rant about how the “current paradigm of phylogenetics focuses on banal details…” etc. Basically, he quits.
