Hello everyone! I have an Oncidium Twinkle. There is no clonal name
other than 'white' on the label. From searching this group's past
e-mails, I've learned that not all clones of this plant are fragrant,
and those that do have a fragrance vary in it's intensity.
However, I'm confused. Please let me know if I'm understanding this
correctly -
1. Onc. 'A' x Onc. 'B' = Onc. Twinkle
2. One of the seedlings was given the clonal name 'Fragrance Fantasy' ,
but every seedling of this cross is called Onc. Twinkle.
3. My plant is of the same grex as 'Fragrance Fantasy' - if it is one
of the seedlings of the original cross.
4. If it is a remake using different plants than originally used (even
though they would be the same two species), they would still carry the
grex name of Twinkle , but would be unrelated to the original grex.
Thanks!

Hi, Bob.

I think maybe you're using the term "grex" a bit more specifically than I.
If you equate the word with "cross," it's more common. Other than that,
you're on the right track.

The grex (cross) A x B or B x A will always be Twinkle, the grex name.
That applies to every breeding, no matter which plants of Oncidiums A & B
are used, and to any Twinkle x Twinkle cross or Twinkle selfing.

'Fragrance Fantasy' was a single cultivar of Twinkle, and that cultivar name
applies to divisions and clones of that original plant only.

Out of curiosity (or maybe I just read too much into your post - it IS 5:30
and I haven't had that first cup of coffee yet) what makes you think yours
is from Moir's original cross of Onc. cheirophorum and Onc. ornithorhynchum?
It was registered in 1958!

HI Ray! I don't think I have one of the original plants of that grex.
In fact my particular plant was purchased at the Philadelphia flower
show last year from Parkside. It was a very healthy 4"pot. After it
was done flowering, I divided it into five pots and now each of them is
growing and flowering!!!
The label that came with the plant is : Onc. Twinkle - white
I knew of 'Fragrance Fantasy' and originally thought all Twinkle's
were fragrant.
My questions were from trying to get a handle on how my plant was
related to the original cross. I persist in thinking of plant
relationships in human terms - parent/child, siblings, cousins, etc.
and was just curious.
Another thing I learned from your answer was that a Twinkle x Twinkle
cross would also be Twinkle - If asked, I would have guessed it would
have been given a new grex name, since only Onc cheirophorum x Onc
ornithorynchum could be called Twinkle.
