Thanks, and indeed Karsty, that is what the authors of the article propose. They tried out natural resources of phosphorus like moose dung and birch litter, both setups gave germination. Contrary to big seeds, small spores don't have a reserve amount of nutrients with them. It isn't too surprising that they need some help to get started.
Hi,
last year I wasn't very active and so I haven't even posted the pictures from the end of last season. Here are the pictures of my tuberous drosera from April 2017.
Starting with Drosera aff. bulbosa Caballo Blanco form
Drosera yilgarensis
Drosera whittakeri
A young Drosera lunata
Drosera zonaria from Oakford
Drosera lowriei "Gigant"
Drosera aff. palladia south coast form
Drosera stricticaulis The Lakes
Two pictures of Drosera squamosa
Drosera rosulata gigant swamp form
Drosera rosulata gigant hills form
and a Drosera rosulata without location
Drosera purpurascens
Not the most fascinating picture ever but a plant that is not so often seen in culture: Drosera prostrata.
A flowering Drosera obriculata
Will be continued.
Best regards from Berlin

Carl, I think on a specialist site like this we do need to ensure that we use correct terminology otherwise people may finish up using silly kindergarten terms like "leaf-pullings" etc.
Stephen is currently in abstentia so someone has to say it
Hi Mike,
I noticed something similar to you--I sowed some of Stephen's Cephalotus seeds in September 2011. Half of them I put outside in a growhouse and the other half I put in my [warm] terrarium. In December, the ones in the terrarium had started to germinate. I then brought in the ones from outside as it was getting quite cold (as in below freezing) and they also started to germinate.
While I note this is a small sample size, I won't bother stratifying any Cephalotus seeds in the future.
