Some days before I got one seedling from a friend and it looks as yours. I told him it looks like A . angustifolia, but he told me this is quite different to his angustifolia-seedlings.
I sowed out in the 80- th many angustifolia and I think they looked like this araucana x angustifolia-seedling.

In spring I will get a angustifoilia-seedling from him and then I will compare.

I have grown several dozen of these putative A. ang. x arauc. F2. My impression has been that they are just A. angustifolia. I don't see much in the way of araucana characteristics.

Salicaceace Can you post a photo of your seedlings
yes im sure they are normal angustifolias.The seed
However is from Argentina.

Interested by some seeds, maybe someone have some fro me ?

Clément,

my friend got the seed from Tobias Spanner, München
www.palmeperpaket.de
as F2-hybrids.

Just to compare them side by side. At the forefront of the picture there are five a. araucana seedlings counting from left to right side. The rightmost seedling is an a. angustifolia.

Any smaller and there won't be any morphological features present to use as a basis for assessment and comparison at all. These plants need to be looked at when they are much farther along.

Actually there are differences, a. angustifolia seed is, at least, twice the size of the a. araucana seed. The leaves of a. angustifolia are narrow than the leaves of a. araucana, etc. I have upload two close-ups of each seedling to imageshack:

Also significant differences in the seed:
A. angustifolia - seed with A. araucana - seed with 2-4 cm apical spine
