Need HELP!!!

[dodidoki]

I look for plant photo of paph. wentworthianum!(especially leaf pattern!!!)
If anyone has, please post it or PM me!!!Thanks!

Did you try googling?

Did you try googling?

Yes, but found nothing, only flower photos.

Here's a plant photo of our Paph. wentworthianum `824' clone, currently in bud, to show the leaf tessellations. Hope this helps!

Thanks, Tom, it is similar as mine!

Nice plant Tom!! Aren't they hard to grow?

 

[tomkalina]

They are certainly not among the easiest Paph. species to grow. Because the original population was so small and the gene pool limited, they are also very difficult to propagate - which pretty much explains why you never see seedlings available.

Two previous attempts at selfing the '824' clone resulted in a dramatic reduction in plant vigor, to the extent we did not allow the seed capsule to reach maturity before sacrificing it to reduce plant stress. We also tried sibling crosses with our clone '825', but the pollination was never successful. Couple this with the tendency to have only two growths at any given time (One new growth and old, dying one) preventing division, you end up with one very expensive plant.

Anyone fortunate enough to own one of these should do everything possible to conserve it. Our two clones originated with Birchwood Orchids, and were aquired when we purchased the collection from the Clement's estate.

Thanks,

Wow! somebody should put it in a seed bank for preservation.

 

[dodidoki]

So this is mine. Could it be????

Istvan,

It's possible, although the tessellations appear to be more distinct on your plant's leaves than ours. I can't be sure, because I've only seen four clones of this species in 40 years and I'm not sure how variable the leaves could be from clone to clone. The leaves on both our Paph. wentworthianum clones are also rather thick - like Paph. mastersianum. The tessellations are also similar to those on Paph. mastersianum - rather muted.

Thanks,

Tom

Eric,

I agree w the seed bank idea; the only problem is getting the seed to begin with. We were successful (finally) in propagating Paph. randsii after many years of trying, but wentworthianum appears to be a lot more difficult than randsii.

Thanks,

clones?

 

[tomkalina]

Eric,

I use the word "clone" not in the sense of DNA replication, but to differentiate one individual from another in a population of species. i.e. Paph. wentworthianum `824' is a different clone than Paph. wentworthianum `'825'. Also, Paph. venustum `Foxcatcher' FCC/AOS is a different clone than Paph. venustum `Fox Valley', although they are the same species. The names or numbers within the single quotes are called clonal names to differentiate one individual from another. :wink:

 

[dodidoki]

Thanks, Tom. I 'd like to ask you to send a photo onto forum if yours will be in bloom (if you have previous photo, please send it, too!). If mine will be in bloom we will see the truth...(I hope, because mine bougainvilleanums and zieckianums have similar leaves and they are the closest relatives to wenth.)

No, I meant can they be tissue or meristem cultured?

I found a nice in situ photo(a little dark...).

Istvan,

I had dinner with Jack Fowlie prior to a Paph Guild meeting many years ago before he passed away and asked him why the backgrounds on many of his 'in-situ' habitat photos was so dark while the flowers actually looked high-lighted. He told me it was because the habitat was so shady, the only way to get a photo at all was to use a flash. This resulted in very dark backgrounds.

Eric,

As far as I know, clonal replication has been all but impossible with Paphs. Maybe drorchid or Olaf could give us the scientific background on this?

Thanks,

i thought the thing with Paphs/Phrags was that they could only be 'cloned' in flask while they are germinating. something about making the protocorms split, i think.

 

[NYEric]

I think the problem is that no-one has yet identified the tissue cells in paphs yet that can replicate a whole plant.

fine. you say tomato, i say small, roundish, red thing that people put in salads....or maybe not.
