David,
Don't lose hope on the seeds yet. Allow the seeds to dry out for 6 months (Summer) and try again in the coolest part of the year. Like I mention in the other thread nighttime lenght and temperature are signals that the seeds will look for germination. Even then it will take 6 - 12 weeks for germination. Also Gilliberic Acid (a plant hormone) is handy for kick starting the germination.

I think there is several chemicals release by the gum trees also involed, with some non CP natives, heat itself.
I have seen the SA version of the stricticularis in cultivation, once. An ACPS member from Port Lincolin brought pot in several years ago. It smaller in all parts than it WA counterpart. It found in one swamp south of the Airport. He reported it took 5 years to reach heigh of about 11cm. I have heard a rumour of Drosera ramellosa in the very tip of Eyre Peniusla.
Anyone got seeds of stricticularis ?

Greg Bourke Reports that nearly all the species require two seperate clones to produce any viable quantity of seed, You can also make Tuberous Drosera Hybrids such as Greg and I have done recently.:1thumbup:

I watched a TV program on the discovery of Ethylene in 1994, it was the only single chemical responcible for bush regeneration, Heat itself has nothing to do with Tuberous Drosera.

Time for some more photos I think.

Drosera macrantha ssp.emerae also known now as Stricticularis ssp.emerae which makes more sence to me.

Ok, ok, lucky I have not thrown that few pots away. However, i've moved it away from my terrarium and the media is dried up for about 1 month + already. Will wait for the rains in Sept-December where it is cooler to try again.

Re: Drosera and some extremely rare tuberous
 
Yes you are right about heat with Drosera it other genera like Banksia that need heat. What types of hybrids have you managed to produce? Any cross of the different subgroups?
Interesting that eremea is been classifed as subspecies of stricticularis. I have try to cross it with macrantha with no success. I would still be inclined to see it more related to macrantha but as seperate species. It is scrambling herb unlike the stricticularis I saw which had habit closer to menzesii ssp menzesii. Interesting about eremea is it does not release it pollen until after 2pm.

And finally, Drosera menziesii ssp. menziesii the first tuberous species I had luck with, I got these as two tubers way back in 2002 and from then they have multiplyed to over 50 plants, not bad eh?.

Re: Drosera and some extremely rare tuberous
 
Yes the Pink Rainbow menzesii ssp menzesii is a good one to start with. I started with about dozen in 1999 I have now around 2000 - 3000 plants. I found average of 3.5 tuber per tuber planted, per year.

Re: Drosera and some extremely rare tuberous
 
Wow, nice. Got any photos of them in flower?.

Re: Drosera and some extremely rare tuberous
 
Do either of you have D. zigzagia in your collections. I recently saw pictures of this flowering for the first time a week ago from a collector here in Mlebourne. It has stunning yellow flowers.

Khoas 5th August 2008 10:20 AM

Re: Drosera and some extremely rare tuberous
 
I wish I had zigzagia. It has yellow flowers? I thought only mooreii had yellow flowers in the tuberous sundews. I know it is very closely related to gigantea.David, Am looking for any photos of my menzesii. I will have them posted as soon I find them.
