I have this superb plant, which was given under Raoulia X Leucogenes. I don't see any Leucogenes influence in the flowers, although the leaves remind a bit of it.
Can anyone confirm this hybrid, or tell me if possible if it would be something else?

The individual rosettes are not more than 1cm wide.

There is indeed a x Leucoraoulia hybrid.
See this paper:

Tim Ingram has a photo of one in the NARGS Forum:

There's a plant called x Leucoraoulia loganii but I'm not sure if this is it.
We used to grow a plant of this type which had a different name, I think, but I cannot recall what it was. I'll need to ask Ian if he remembers! We grew it from NZ seed and used to exhibit.

You are a living encyclopedia Maggi ;)
Looks like knowing what I grow is going to be a hard work!
Thank you for your precious help, as always :-*

We grow something under the name Raoulia x Loganii but I don't think this is it, every part looks a bit too big. If that plant is eliminated, yours, Philippe could well be a hybrid between a Leucogenes and a Raoulia. I've not come across one and hadn't heard of one.
A brief PS, what do newly germinated seedlings of Hegemone lilacina look like?
-
I thought that Leuocraoulia x loganii and Raoulia x loganii were the same thing :-\
-
It could well be Maggi. I haven't seen the bigeneric ame used here but then I'm not always as attentive as I should be. At 1cm across, Philippe's rosettes are quite large even for R.x Loganii, and his plant is ENORMOUS! I've not seen one myself, wider than maybe 30cms across. Mine usually reach about 18-20cms before browning off!
-
About the Hegemone seedlings, mines are still on cotyledon stage, since may. The cotyledons begin to turn yellow/brown, and I guess no true leave will come untill next year.
From overall appearance, the seedlings really don't like special at all, it could be a thousand other buttercup' family members.
I may post a pic this evening if I don't forget again to take it, as I did yesterday :-X

Here the Hegemone seedlings.

I also have a question: Raoulia subsericea grows in the bed, but what difference does it have with R.glabra? Looking on the web, I find them to be very similar...Wouldn't be the genera Raoulia something very...nebulous...?
-
I can't help you with that Raoulia question Philippe except that under it's silver, R. subsericea has a green colour. Where are the other NZers who will certainly know more than I do about these plants?
My Hegemone seedlings do look like yours. They're not Holubec's, but came from the AGS list last January.

Philippe , I think your N.Z. plant is a Raoulia species and not the bigeneric hyb. xLeucoraoulia loganii (old name : Raoulia xloganii ).
Lesley and Maggi, I have been growing x Leucoraoulia xloganii for at least 20 years ( the late Jack Scott brought it over ) and it never spreads like Philippe's plant -but forms a bun and usually gives up the ghost after 4-6 years ,
.but is very easy from cuttings .

Thanks, Otto. I was just thinking fondly of you as I showed a coffee and piece of cake no mercy whatsoever!
-
Your experience Otto just about mirrors mine. I would be astounded if Philippe's plant is the same as the one we grow as Raoulia x Loganii.
-
Our plant of the hybrid never got to be the size of Philippe's spreading beauty, that's for sure.
It is an outstanding specimen of a silvery carpet.

Looking and looking again at pics of Raoulia X loganii on the web makes me feel my plant is really something else.
As Otto said, the growth habit isn't the same.
I have had the plant as a living specimen a few years ago, from a rock gardener, who had it probably from seed from the seed exchanges. So surely the "hybrid" plant is of garden origin, and may have hybridised a little more there, as this wasn't yet enough :P
-
Maggi and Philippe , took a picture today of one of my small plants of the true X Leucoraoulia loganii -so that should settle the issue .

Thank you Otto for the pic.
