Dionea x drosera?

Clint

Stay chooned in for more!
if any of you have been to the uk forum, in the general discussion section theres a post about a D. Regia x dionea. i say its perposterous. they say adrian slack did it.

what do you think?

by the way, i was watching the osbournes and ozzy had trouble getting off of his couch. he said it was like a venus flytrap . :)
 
it is not possible to cross two different genus of any living thing on this planet, but you can cross two different species

Sorry to disagree: this cross has been attempted between D. regia and Dionaea. I can't recall all the particulars, but I do know the genetic material was exchanged between them. I believe the seed produced was either defective, ot that the seedlings aborted right after germination. I think this was a listserve dicussion sometime in the past, and a search of the archives will reveal more details. Please give us an update if you learn anything further on this subject.
 
Actually there are thousands and thousands of hybrids between different genera in just the Orchid family alone.

Wow, that would be wild.

I have tried but I can't even imagine what that would look like.
I can't wait to see if it's true.
 
Miltinopsis is an intergeneral (is that a word) orchid hybrid...

Or so Khai told me *looks over at Khai*...

Intergeneric, I think, or is it intrageneric....one of them anyways :)
 
Inter- is the correct prefix

It is easiest to remember by analogy, think interstate (between states)

I believe it has been done with success with fruits.

ok i've been away lately.

i think its really cool!! is there anyway you could "make" the seeds germinate?

speaking of orchids, i think its a shame that orchids are so much more popular than cp's. cp's look great all the time and orchids are only beautiful when in flower.

Hi all, Ivan here,
This is a subject I find especially interesting. In the 1985 CPN December
issue I wrote the article 'Evolution of the Venus' Flytrap'. In the
article I detailed the evolutionary steps from sundew to VFT. At the
time, Drosera falconeri had recently been discovered. When I submitted
the article, Joseph Mazrimas wrote me that he felt that D. falconeri
might be an ancestor of VFT. After studying the plant myself, I do not
believe this is true. Still, the similarity in my hypothetical drawing in
the article, as Mr. Mazrimas suguested, is astonishing. This is why I say
that D. falconeri is representative of a missing link, though not
actually the genuine article.

After much study I feel that D. regia is the most closely related sundew
to VFT. In addition to the shared characteristics mentioned by Sean and
Jan here are the pollen. D. regia pollen is unlike any other sundew and
most like that of VFT. The chromosome counts are especially telling (if
correct). In biology there is a general rule in respect to archaic
species which have developed into more moderns and differing by one pair
of chromosomes, such as this case, VFT = 32, D. regia = 34. The older
species will actually have the higher count. This is because it is more
simple to lose a pair rather than gain one. This rule holds true with the
aboriginal horse having one pair of chromosomes more than the
domesticated horse. Also consider the chimpanzee has one pair more than
we Humans. Incedently, the wild horse ancestor and domestic horse may
interbreed and often produce fertile offspring, despite the chromosome
difference.

I have tried cross pollinations of many different sundews with VFT. All
will be surprised to hear that some did cross, though the hybrids did not
survive long. I have not had flowering of D. regia and VFT simultaneously
yet. I feel that maybe these two might be most compatible.

wow, truly amazing. William, I agree on Pyros avatar, it kinda resembles one of my hobbies...

, i am a pyro myself i thank you,

Here's something else to throw in the mix...

I read that recently a very close relationship (genetically) between aldrovanda and the VFT had been established....as if they were common children of one ancestor. Now THAT would be an interesting cross....
 
  • #16
they once bred a heliamphora with a darlingtonia but the seedlings were very weak and they died so i think that dionaea with drosera regia is possible .
 
  • #17
Justlikeapill,

Yes, that is the discussion I remembered!

Schloaty,

I agree, this cross seems (at least on the face of it) to be very possible. Phil Sheriden at Meadowview Biological Station has abundant Aldrovanda in a naturalized setting. I believe I will write to him and ask if his plants ever flower. If they do, perhaps I can interest him in the experiment!

I wonder if it were successful if the plants would be aquatic or terresterial?
 
  • #18
That would be awesome. An aldrovanda with huge traps... or an aquatic VFT! Seems a bit too good to be true, doesn't it?

Goldtrap, do you have a reference for that cross? I think it sounds very unlikely, but i'd like to be proven wrong!
 
  • #19
i have no physical proof but i plead not guilty , lol

, j/k . there was a post about it along time ago here .
