  Re: [Aroid-l] Sauromatum x Pinellia hybrid.... and others...
From: "Tony Avent" <tony at plantdelights.com> on 2010.07.07 at 20:28:23(21163)

The petiole pattern on Saurmatum opens up yet another can of worms...or
would the term maggots be more appropriate. The difference between the
petioles of Sauromatum venosum 'Indian Giant' and typical Sauromatum venosum
is the size and amount of spots. S. 'Indian Giant' has large spots, but the
are sparse. The typical S. venuosum, therefore, has much smaller spots and
more of them. We planted the two parents side by side and gathered op seed,
of which we have now flowered nearly 1000 plants. The petioles patterns are
a total mix, with even showing no spots. If the S. 'Indian Giant' was a
tetraploid, the crosses back to the typical form should be probably sterile
triploids, which does not seem to be the case.

On our purported hybrid, the petiole spots are closer to typical S. venosum,
which is what I would anticipate with a cross of Pinellia (no spots) and
Sauromatum (spots). I would consider the multiple shoots from the same corm
and the lack of a fully developed flower as the most compelling evidence of
intergeneric hybridization. You should be able to page back and forth to
see the flower image on the gallery, but if not, go to
