hybrid L weddellianum x L insigne hybrid possible?

[Pal Meir]

I'm trying to grow a hybrid between L weddellianum and L insigne. The 4th flower from N°1304 served as the mother tree and the pollen came from N°1401. At the beginning of January 2024 I pollinated around 30 pistillate flowers several times, but to date only three flowers have survived, after one (#2) came off the palm the day before yesterday because it was hollow.

Half a month later: 

And on 1st February:

 

Eight flowers seemed to be pollinated:

But only four grew bigger:

But then fruit #2 fell off. It was completely hollow.

As of today, only three fruits remain. Whether they are also hollow cannot currently be determined. 

I hope they develop into viable fruits; #4 looks a bit weaker though ...

Sending good vibes your way that you are successful. If not I hope you continue to try.

Now there are only two left:

And now it's just one. — And Henderson (1995) had claimed that L weddellianum and L insigne should only be one and the same species. ☹️

I don‘t think that I would have more success in the future. Maybe @Alberto could try it …

My thoughts are that both species must be easily crosseble... In the past I crossed L. weddelianum x L. hoehnei very easily. Maybe other factors interfered with your attempt, like temperature, pollen viability or other....

I have several mature L. weddelianum x L.hoehnei

The only surviver not germinating so far … The pollen from N°1401 were quite old.
