Hi Gary
It seems cuttings go through 2 phases, first: production of roots from the piece of petiole.
That's the case of first picture. Then there is production of a little tuber, 0.5 - 1cm diam.
The first stem is producted by this little tuber. At the begining, there is just a green eye on the tuber and a few roots
start to grow at the base of this green shoot. Only after these roots develop, the stem will start to grow. So, when stems grow, there is already a tuber.
Tropicbreeze:
I don't agree with you, the first step of growth is dead easy, there is no dormancy and stems will grow one after another. (one to one and a half year)
Problems arrive with the first real dormancy, tubers dry very fast if kept to dry but also rot fast if kept to wet. In addition, tuber will awake when it wants.
On my experience, longer is the dormancy, tougher is the awakening.

Hello
After 6 months finger crossed, I had the chance to succeed in A, titanum leaf cutting.
Nothing really new, I just followed this recipe : http://forums.gardenweb.com/discussions/1686545/amorphophallus-titanum-leaf-cutting
Cut a part of the leaf the 4th April, in July I was obliged to repot the cuttings because of a substrate gnat infestation, just took the opportunity to take a pic.
5 rooted leaf portions out of 7, then I had to wait 2 more months before the first stem appeared.

Hi Fernando
You are absolutely right,
It is interesting to see the morphological differences between both clones.
It would be interesting as you said, to collect some more field data.
On my opinion, despite it doesn't form plantlets at the top of leaves,
it is more related to P. medusina regarding the shape of flower.

Hi
More simple, just mix 10 gr of sulfuric acid (37%) with 90 gr of water
You will have a 3.7% solution
Linuxman :
Just be careful you mix volume and weight :-)

Hi Stephan
Very impressive as usual

Hi
Never try another acid, because sulfuric acid works very well.
Don't think acetic acid will work, not strong enough certainly hydrochloric acid
will also work. Many seeds can germinate only after having beeing eaten by birds.
( that's why I try with sulfuric acid, it is not as smelly as hydrochloric acid).

Hi
Only sulfuric acid, this is the acid which is in car battery so it
should be possible to get some at a car mecanic.
You must know the concentration (normally around 30% for car battery)
to make the right dilution.

Hi
Definitely, the best way to get near 100% of germination, even with old seeds
is a treatment with a 4% solution of sulfuric acid.
Just soak the seeds 24h. in a 4% solution of sulfuric acid (H2SO4)
then rinse with water and sow.

Hi Tuberous D
The surface of the soil was 100% sand and completely dry.
About 5 to 10 cm under, it was a mix of sand and black "humus"
still wet.

Hi Martin
I was there mid october, a bit late for tuberous sundews, most of them were already dry
but I was just in time for Byblis.

Hi Stefan
Well done !!
Hope you can keep them alive during winter.

Hi François
I don't know exactly why the flowers had aborted.
I suspect the lack of light, plants are in a greenhouse without
any artificial light. Fortunately this year, winter was very sunny
without any stratus which is normally frequent here in Geneva.

Congrats, gorgeous video, first time I can see pamerida metamorphosis !!
I don't agree with life cycle. It depends on temperature, in winter
it is longer. Young pamerida are really little and nearly invisible.
